Methods

showsPrec :: Int -> Config -> ShowS

show :: Config -> String

showList :: [Config] -> ShowS

data IdentifierQuotation

Configuration for quotation of identifiers of SQL.

Constructors

Quotation Char

Instances

Show IdentifierQuotation

Defined in Database.Relational.Internal.Config

Methods

showsPrec :: Int -> IdentifierQuotation -> ShowS

show :: IdentifierQuotation -> String

showList :: [IdentifierQuotation] -> ShowS

data SchemaNameMode

Schema name qualify mode in SQL string.

Constructors

SchemaQualified

Schema qualified table name in SQL string

SchemaNotQualified

Not qualified table name in SQL string

Instances

Eq SchemaNameMode

Defined in Database.Relational.Internal.Config

Methods

(==) :: SchemaNameMode -> SchemaNameMode -> Bool

(/=) :: SchemaNameMode -> SchemaNameMode -> Bool

Show SchemaNameMode

Defined in Database.Relational.Internal.Config

Methods

showsPrec :: Int -> SchemaNameMode -> ShowS

show :: SchemaNameMode -> String

showList :: [SchemaNameMode] -> ShowS

data ProductUnitSupport

Unit of product is supported or not.

Constructors

PUSupported

PUNotSupported

Instances

Show ProductUnitSupport

Defined in Database.Relational.Internal.Config

Methods

showsPrec :: Int -> ProductUnitSupport -> ShowS

show :: ProductUnitSupport -> String

showList :: [ProductUnitSupport] -> ShowS

data NameConfig

NameConfig type to customize names of expanded templates.

Constructors

NameConfig

Fields

• recordConfig :: NameConfig

  Configurations related to the names of generated record types and their field labels.

• relationVarName :: String -> String -> VarName

  Function to build the name of Relation representing the table. The first argument is the scheme name, and second argument is the table name.

Instances

Show NameConfig

Defined in Database.Relational.Internal.Config

Methods

showsPrec :: Int -> NameConfig -> ShowS

show :: NameConfig -> String

showList :: [NameConfig] -> ShowS

defaultNameConfig :: NameConfig

Default implementation of NameConfig type.

defaultConfig :: Config

Default configuration of Config. To change some behaviour of relational-query, use record update syntax:

  defaultConfig
    { productUnitSupport            =  PUSupported
    , chunksInsertSize              =  256
    , schemaNameMode                =  SchemaQualified
    , normalizedTableName           =  True
    , verboseAsCompilerWarning      =  False
    , disableOverloadedProjection   =  False
    , disableSpecializedProjection  =  False
    , identifierQuotation           =  NoQuotation
    , nameConfig                    =
       defaultNameConfig
       { recordConfig     =  defaultNameConfig
       , relationVarName  =  \schema table -> varCamelcaseName $ table ++ "_" ++ scheme
       -- ^ append the table name after the schema name. e.g. "schemaTable"
       }
    }
