type Rep SqlBuilder

type Rep SqlBuilder = D1 * (MetaData "SqlBuilder" "Database.PostgreSQL.Query.SqlBuilder.Builder" "postgresql-query-3.4.0-1WzfIqDMZGFGRTXBI6k643" True) (C1 * (MetaCons "SqlBuilder" PrefixI True) (S1 * (MetaSel (Just Symbol "sqlBuild") NoSourceUnpackedness NoSourceStrictness DecidedLazy) (Rec0 * (Connection -> LogMasker -> IO SqlBuilderResult))))

Running

runSqlBuilder :: Connection -> LogMasker -> SqlBuilder -> IO (Query, ByteString)

Returns query string with log bytestring

Building

emptyB :: SqlBuilder

Typed synonym of mempty

mkValue :: ToField a => a -> SqlBuilder

Shorthand function to convert single field value to builder

mkMaskedValue :: ToField a => a -> SqlBuilder

Shorthand function to convert single masked field value (which should not be shown in log)

sqlBuilderFromField :: ToField a => FieldOption -> a -> SqlBuilder

Unsafe

sqlBuilderPure :: Builder -> SqlBuilder

Lift pure bytestring builder to SqlBuilder. This is unsafe to use directly in your code.

sqlBuilderFromByteString :: ByteString -> SqlBuilder

Unsafe function to make SqlBuilder from arbitrary ByteString. Does not perform any checks. Dont use it directly in your code unless you know what you are doing.
