Database.Persist.Sql

This module is the primary entry point if you're working with persistent on a SQL database.

Getting Started

First, you'll want to define your database entities. You can do that with "Database.Persist.Quasi."

Then, you'll use the operations

RawSql and PersistFieldSql

class RawSql a where

Class for data types that may be retrived from a rawSql query.

Methods

rawSqlCols :: (Text -> Text) -> a -> (Int, [Text])

Number of columns that this data type needs and the list of substitutions for SELECT placeholders ??.

rawSqlColCountReason :: a -> String

A string telling the user why the column count is what it is.

rawSqlProcessRow :: [PersistValue] -> Either Text a

Transform a row of the result into the data type.

class PersistField a => PersistFieldSql a where

Tells Persistent what database column type should be used to store a Haskell type.

Examples

Simple Boolean Alternative

data Switch = On | Off
  deriving (Show, Eq)

instance PersistField Switch where
  toPersistValue s = case s of
    On -> PersistBool True
    Off -> PersistBool False
  fromPersistValue (PersistBool b) = if b then Right On else Right Off
  fromPersistValue x = Left $ "File.hs: When trying to deserialize a Switch: expected PersistBool, received: " <> T.pack (show x)

instance PersistFieldSql Switch where
  sqlType _ = SqlBool

Non-Standard Database Types

If your database supports non-standard types, such as Postgres' uuid, you can use SqlOther to use them:

import qualified Data.UUID as UUID
instance PersistField UUID where
  toPersistValue = PersistLiteralEncoded . toASCIIBytes
  fromPersistValue (PersistLiteralEncoded uuid) =
    case fromASCIIBytes uuid of
      Nothing -> Left $ "Model/CustomTypes.hs: Failed to deserialize a UUID; received: " <> T.pack (show uuid)
      Just uuid' -> Right uuid'
  fromPersistValue x = Left $ "File.hs: When trying to deserialize a UUID: expected PersistLiteralEncoded, received: "-- >  <> T.pack (show x)

instance PersistFieldSql UUID where
  sqlType _ = SqlOther "uuid"

User Created Database Types

Similarly, some databases support creating custom types, e.g. Postgres' DOMAIN and ENUM features. You can use SqlOther to specify a custom type:

CREATE DOMAIN ssn AS text
      CHECK ( value ~ '^[0-9]{9}$');

instance PersistFieldSQL SSN where
  sqlType _ = SqlOther "ssn"

CREATE TYPE rainbow_color AS ENUM ('red', 'orange', 'yellow', 'green', 'blue', 'indigo', 'violet');

instance PersistFieldSQL RainbowColor where
  sqlType _ = SqlOther "rainbow_color"

newtype EntityWithPrefix (prefix :: Symbol) record

This newtype wrapper is useful when selecting an entity out of the database and you want to provide a prefix to the table being selected.

Consider this raw SQL query:

SELECT ??
FROM my_long_table_name AS mltn
INNER JOIN other_table AS ot
   ON mltn.some_col = ot.other_col
WHERE ...

We don't want to refer to my_long_table_name every time, so we create an alias. If we want to select it, we have to tell the raw SQL quasi-quoter that we expect the entity to be prefixed with some other name.

We can give the above query a type with this, like:

getStuff :: SqlPersistM [EntityWithPrefix "mltn" MyLongTableName]
getStuff = rawSql queryText []

The EntityWithPrefix bit is a boilerplate newtype wrapper, so you can remove it with unPrefix, like this:

getStuff :: SqlPersistM [Entity MyLongTableName]
getStuff = unPrefix @"mltn" <$> rawSql queryText []

The symbol is a "type application" and requires the TypeApplications@ language extension.

Since: 2.10.5

Constructors

EntityWithPrefix

Fields

• unEntityWithPrefix :: Entity record

Instances

(PersistEntity record, KnownSymbol prefix, PersistEntityBackend record ~ backend, IsPersistBackend backend) => RawSql (EntityWithPrefix prefix record)

Defined in Database.Persist.Sql.Class

Methods

rawSqlCols :: (Text -> Text) -> EntityWithPrefix prefix record -> (Int, [Text])

rawSqlColCountReason :: EntityWithPrefix prefix record -> String

rawSqlProcessRow :: [PersistValue] -> Either Text (EntityWithPrefix prefix record)

unPrefix :: forall prefix record. EntityWithPrefix prefix record -> Entity record

A helper function to tell GHC what the EntityWithPrefix prefix should be. This allows you to use a type application to specify the prefix, instead of specifying the etype on the result.

As an example, here's code that uses this:

myQuery :: SqlPersistM [Entity Person]
myQuery = fmap (unPrefix @"p") $ rawSql query []
  where
    query = "SELECT ?? FROM person AS p"

Since: 2.10.5

Running actions

Run actions in a transaction with runSqlPool.

runSqlPool :: forall backend m a. (MonadUnliftIO m, BackendCompatible SqlBackend backend) => ReaderT backend m a -> Pool backend -> m a

Get a connection from the pool, run the given action, and then return the connection to the pool.

This function performs the given action in a transaction. If an exception occurs during the action, then the transaction is rolled back.

Note: This function previously timed out after 2 seconds, but this behavior was buggy and caused more problems than it solved. Since version 2.1.2, it performs no timeout checks.

runSqlPoolWithIsolation :: forall backend m a. (MonadUnliftIO m, BackendCompatible SqlBackend backend) => ReaderT backend m a -> Pool backend -> IsolationLevel -> m a

Like runSqlPool, but supports specifying an isolation level.

Since: 2.9.0

runSqlPoolNoTransaction :: forall backend m a. (MonadUnliftIO m, BackendCompatible SqlBackend backend) => ReaderT backend m a -> Pool backend -> Maybe IsolationLevel -> m a

Like runSqlPool, but does not surround the action in a transaction. This action might leave your database in a weird state.

Since: 2.12.0.0

runSqlPoolWithHooks

Arguments

:: forall backend m a before after onException. (MonadUnliftIO m, BackendCompatible SqlBackend backend)

=> ReaderT backend m a

-> Pool backend

-> Maybe IsolationLevel

-> (backend -> m before)

Run this action immediately before the action is performed.

-> (backend -> m after)

Run this action immediately after the action is completed.

-> (backend -> SomeException -> m onException)

This action is performed when an exception is received. The exception is provided as a convenience - it is rethrown once this cleanup function is complete.

-> m a

This function is how runSqlPool and runSqlPoolNoTransaction are defined. In addition to the action to be performed and the Pool of conections to use, we give you the opportunity to provide three actions - initialize, afterwards, and onException.

Since: 2.12.0.0

acquireSqlConn :: (MonadReader backend m, BackendCompatible SqlBackend backend) => m (Acquire backend)

Starts a new transaction on the connection. When the acquired connection is released the transaction is committed and the connection returned to the pool.

Upon an exception the transaction is rolled back and the connection destroyed.

This is equivalent to 'runSqlConn but does not incur the MonadUnliftIO constraint, meaning it can be used within, for example, a Conduit pipeline.

Since: 2.10.5

acquireSqlConnWithIsolation :: (MonadReader backend m, BackendCompatible SqlBackend backend) => IsolationLevel -> m (Acquire backend)

Like acquireSqlConn, but lets you specify an explicit isolation level.

Since: 2.10.5

runSqlConn :: forall backend m a. (MonadUnliftIO m, BackendCompatible SqlBackend backend) => ReaderT backend m a -> backend -> m a

runSqlConnWithIsolation :: forall backend m a. (MonadUnliftIO m, BackendCompatible SqlBackend backend) => ReaderT backend m a -> backend -> IsolationLevel -> m a

Like runSqlConn, but supports specifying an isolation level.

Since: 2.9.0

withSqlPoolWithConfig

Arguments

:: forall backend m a. (MonadLoggerIO m, MonadUnliftIO m, BackendCompatible SqlBackend backend)

=> (LogFunc -> IO backend)

Function to create a new connection

-> ConnectionPoolConfig

-> (Pool backend -> m a)

-> m a

Creates a pool of connections to a SQL database which can be used by the Pool backend -> m a function. After the function completes, the connections are destroyed.

Since: 2.11.0.0

createSqlPool :: forall backend m. (MonadLoggerIO m, MonadUnliftIO m, BackendCompatible SqlBackend backend) => (LogFunc -> IO backend) -> Int -> m (Pool backend)

createSqlPoolWithConfig

Arguments

:: forall m backend. (MonadLoggerIO m, MonadUnliftIO m, BackendCompatible SqlBackend backend)

=> (LogFunc -> IO backend)

Function to create a new connection

-> ConnectionPoolConfig

-> m (Pool backend)

Creates a pool of connections to a SQL database.

Since: 2.11.0.0

withSqlConn :: forall backend m a. (MonadUnliftIO m, MonadLoggerIO m, BackendCompatible SqlBackend backend) => (LogFunc -> IO backend) -> (backend -> m a) -> m a

Create a connection and run sql queries within it. This function automatically closes the connection on it's completion.

getFieldName :: forall record typ m backend. (PersistEntity record, PersistEntityBackend record ~ SqlBackend, BackendCompatible SqlBackend backend, Monad m) => EntityField record typ -> ReaderT backend m Text

persistent offers a set of functions that are useful for operating directly on the underlying SQL database. This can allow you to use whatever SQL features you want.

Consider going to <https://hackage.haskell.org/package/esqueleto esqueleto> for a more powerful SQL query library built on persistent.

rawQuery :: (MonadResource m, MonadReader env m, BackendCompatible SqlBackend env) => Text -> [PersistValue] -> ConduitM () [PersistValue] m ()

rawQueryRes :: (MonadIO m1, MonadIO m2, BackendCompatible SqlBackend env) => Text -> [PersistValue] -> ReaderT env m1 (Acquire (ConduitM () [PersistValue] m2 ()))

rawExecute

Arguments

:: (MonadIO m, BackendCompatible SqlBackend backend)

=> Text

SQL statement, possibly with placeholders.

-> [PersistValue]

Values to fill the placeholders.

-> ReaderT backend m ()

Execute a raw SQL statement

rawExecuteCount

Arguments

:: (MonadIO m, BackendCompatible SqlBackend backend)

=> Text

SQL statement, possibly with placeholders.

-> [PersistValue]

Values to fill the placeholders.

-> ReaderT backend m Int64

Execute a raw SQL statement and return the number of rows it has modified.

rawSql

Arguments

:: (RawSql a, MonadIO m, BackendCompatible SqlBackend backend)

=> Text

SQL statement, possibly with placeholders.

-> [PersistValue]

Values to fill the placeholders.

-> ReaderT backend m [a]

Execute a raw SQL statement and return its results as a list. If you do not expect a return value, use of rawExecute is recommended.

If you're using Entitys (which is quite likely), then you must use entity selection placeholders (double question mark, ??). These ?? placeholders are then replaced for the names of the columns that we need for your entities. You'll receive an error if you don't use the placeholders. Please see the Entitys documentation for more details.

You may put value placeholders (question marks, ?) in your SQL query. These placeholders are then replaced by the values you pass on the second parameter, already correctly escaped. You may want to use toPersistValue to help you constructing the placeholder values.

Since you're giving a raw SQL statement, you don't get any guarantees regarding safety. If rawSql is not able to parse the results of your query back, then an exception is raised. However, most common problems are mitigated by using the entity selection placeholder ??, and you shouldn't see any error at all if you're not using Single.

Some example of rawSql based on this schema:

share [mkPersist sqlSettings, mkMigrate "migrateAll"] [persistLowerCase|
Person
    name String
    age Int Maybe
    deriving Show
BlogPost
    title String
    authorId PersonId
    deriving Show
|]

Examples based on the above schema:

getPerson :: MonadIO m => ReaderT SqlBackend m [Entity Person]
getPerson = rawSql "select ?? from person where name=?" [PersistText "john"]

getAge :: MonadIO m => ReaderT SqlBackend m [Single Int]
getAge = rawSql "select person.age from person where name=?" [PersistText "john"]

getAgeName :: MonadIO m => ReaderT SqlBackend m [(Single Int, Single Text)]
getAgeName = rawSql "select person.age, person.name from person where name=?" [PersistText "john"]

getPersonBlog :: MonadIO m => ReaderT SqlBackend m [(Entity Person, Entity BlogPost)]
getPersonBlog = rawSql "select ??,?? from person,blog_post where person.id = blog_post.author_id" []

SQL helpers

deleteWhereCount :: (PersistEntity val, MonadIO m, PersistEntityBackend val ~ SqlBackend, BackendCompatible SqlBackend backend) => [Filter val] -> ReaderT backend m Int64

Same as deleteWhere, but returns the number of rows affected.

Since: 1.1.5

updateWhereCount :: (PersistEntity val, MonadIO m, SqlBackend ~ PersistEntityBackend val, BackendCompatible SqlBackend backend) => [Filter val] -> [Update val] -> ReaderT backend m Int64

Same as updateWhere, but returns the number of rows affected.

Since: 1.1.5

filterClause

Arguments

:: PersistEntity val

=> Maybe FilterTablePrefix

include table name or EXCLUDED

-> SqlBackend

-> [Filter val]

-> Text

Render a [Filter record] into a Text value suitable for inclusion into a SQL query.

Since: 2.12.1.0

filterClauseWithVals

Arguments

:: PersistEntity val

=> Maybe FilterTablePrefix

include table name or EXCLUDED

-> SqlBackend

-> [Filter val]

-> (Text, [PersistValue])

Render a [Filter record] into a Text value suitable for inclusion into a SQL query, as well as the [PersistValue] to properly fill in the ? place holders.

Since: 2.12.1.0

orderClause

Arguments

:: PersistEntity val

=> Maybe FilterTablePrefix

include table name or EXCLUDED

-> SqlBackend

-> [SelectOpt val]

-> Text

Render a [SelectOpt record] made up *only* of Asc and Desc constructors into a Text value suitable for inclusion into a SQL query.

Since: 2.13.2.0

data FilterTablePrefix

Used when determining how to prefix a column name in a WHERE clause.

Since: 2.12.1.0

Constructors

PrefixTableName

Prefix the column with the table name. This is useful if the column name might be ambiguous.

Since: 2.12.1.0

PrefixExcluded

Prefix the column name with the EXCLUDED keyword. This is used with the Postgresql backend when doing ON CONFLICT DO UPDATE clauses - see the documentation on upsertWhere and upsertManyWhere.

Since: 2.12.1.0

Transactions

transactionSave :: MonadIO m => ReaderT SqlBackend m ()

Commit the current transaction and begin a new one. This is used when a transaction commit is required within the context of runSqlConn (which brackets its provided action with a transaction begin/commit pair).

Since: 1.2.0

transactionSaveWithIsolation :: MonadIO m => IsolationLevel -> ReaderT SqlBackend m ()

Commit the current transaction and begin a new one with the specified isolation level.

Since: 2.9.0

transactionUndo :: MonadIO m => ReaderT SqlBackend m ()

Roll back the current transaction and begin a new one. This rolls back to the state of the last call to transactionSave or the enclosing runSqlConn call.

Since: 1.2.0

transactionUndoWithIsolation :: MonadIO m => IsolationLevel -> ReaderT SqlBackend m ()

Roll back the current transaction and begin a new one with the specified isolation level.

Since: 2.9.0

Other utilities

getStmtConn :: SqlBackend -> Text -> IO Statement

mkColumns :: [EntityDef] -> EntityDef -> BackendSpecificOverrides -> ([Column], [UniqueDef], [ForeignDef])

Create the list of columns for the given entity.

data BackendSpecificOverrides

Record of functions to override the default behavior in mkColumns. It is recommended you initialize this with emptyBackendSpecificOverrides and override the default values, so that as new fields are added, your code still compiles.

For added safety, use the getBackendSpecific* and setBackendSpecific* functions, as a breaking change to the record field labels won't be reflected in a major version bump of the library.

Since: 2.11

emptyBackendSpecificOverrides :: BackendSpecificOverrides

Creates an empty BackendSpecificOverrides (i.e. use the default behavior; no overrides)

Since: 2.11

getBackendSpecificForeignKeyName :: BackendSpecificOverrides -> Maybe (EntityNameDB -> FieldNameDB -> ConstraintNameDB)

If the override is defined, then this returns a function that accepts an entity name and field name and provides the ConstraintNameDB for the foreign key constraint.

An abstract accessor for the BackendSpecificOverrides

Since: 2.13.0.0

setBackendSpecificForeignKeyName :: (EntityNameDB -> FieldNameDB -> ConstraintNameDB) -> BackendSpecificOverrides -> BackendSpecificOverrides

Set the backend's foreign key generation function to this value.

Since: 2.13.0.0

data SqlBackend

A SqlBackend represents a handle or connection to a database. It contains functions and values that allow databases to have more optimized implementations, as well as references that benefit performance and sharing.

Instead of using the SqlBackend constructor directly, use the mkSqlBackend function.

A SqlBackend is *not* thread-safe. You should not assume that a SqlBackend can be shared among threads and run concurrent queries. This *will* result in problems. Instead, you should create a Pool SqlBackend, known as a ConnectionPool, and pass that around in multi-threaded applications.

To run actions in the persistent library, you should use the runSqlConn function. If you're using a multithreaded application, use the runSqlPool function.

readToUnknown :: Monad m => ReaderT SqlReadBackend m a -> ReaderT SqlBackend m a

Useful for running a read query against a backend with unknown capabilities.

readToWrite :: Monad m => ReaderT SqlReadBackend m a -> ReaderT SqlWriteBackend m a

Useful for running a read query against a backend with read and write capabilities.

writeToUnknown :: Monad m => ReaderT SqlWriteBackend m a -> ReaderT SqlBackend m a

Useful for running a write query against an untagged backend with unknown capabilities.

type SqlBackendCanRead backend = (BackendCompatible SqlBackend backend, PersistQueryRead backend, PersistStoreRead backend, PersistUniqueRead backend)

A constraint synonym which witnesses that a backend is SQL and can run read queries.

type SqlBackendCanWrite backend = (SqlBackendCanRead backend, PersistQueryWrite backend, PersistStoreWrite backend, PersistUniqueWrite backend)

A constraint synonym which witnesses that a backend is SQL and can run read and write queries.

type SqlReadT m a = forall backend. SqlBackendCanRead backend => ReaderT backend m a

Like SqlPersistT but compatible with any SQL backend which can handle read queries.

type SqlWriteT m a = forall backend. SqlBackendCanWrite backend => ReaderT backend m a

Like SqlPersistT but compatible with any SQL backend which can handle read and write queries.

type IsSqlBackend backend = (IsPersistBackend backend, BaseBackend backend ~ SqlBackend)

A backend which is a wrapper around SqlBackend.

newtype OverflowNatural

Prior to persistent-2.11.0, we provided an instance of PersistField for the Natural type. This was in error, because Natural represents an infinite value, and databases don't have reasonable types for this.

The instance for Natural used the Int64 underlying type, which will cause underflow and overflow errors. This type has the exact same code in the instances, and will work seamlessly.

A more appropriate type for this is the Word series of types from Data.Word. These have a bounded size, are guaranteed to be non-negative, and are quite efficient for the database to store.

Since: 2.11.0
