EmitByteString :: ByteString -> f -> PgSyntaxF f | |
EmitBuilder :: Builder -> f -> PgSyntaxF f | |
EscapeString :: ByteString -> f -> PgSyntaxF f | |
EscapeBytea :: ByteString -> f -> PgSyntaxF f | |
EscapeIdentifier :: ByteString -> f -> PgSyntaxF f |
A piece of Postgres SQL syntax, which may contain embedded escaped byte and
text sequences. PgSyntax
composes monoidally, and may be created with
emit
, emitBuilder
, escapeString
, escapBytea
, and escapeIdentifier
.

data PgCommandSyntax Source #
Representation of an arbitrary Postgres command. This is the combination of
the command syntax (repesented by PgSyntax
), as well as the type of command
(represented by PgCommandType
). The command type is necessary for us to
know how to retrieve results from the database.
