Interface DataType<T>

Type Parameters:

T - The Java type associated with this SQL data type

All Superinterfaces:

Named, QueryPart, Serializable

All Known Implementing Classes:

BuiltInDataType, DefaultDataType

public interface DataType<T>
extends Named

A common interface to all dialect-specific data types.

jOOQ provides built in data types through SQLDataType. Users can define their own data types programmatically by calling asConvertedDataType(Converter) or asConvertedDataType(Binding), for example. Custom data types can also be defined on generated code using the <forcedType/> configuration, see the manual for more details

getArrayType

@NotNull

@NotNull
@NotNull DataType<T[]> getArrayDataType()
                                 throws DataTypeException

Retrieve the data type for an ARRAY of this data type.

Built-in data types, as well as custom data types that have a custom getConverter() can be translated to array data types using Converter.forArrays(). Data types with custom getBinding() cannot be translated to an array data type. Use this idiom, instead:

 // Doesn't work
 DataTypeinvalid input: '<'UserType[]> t1 =
   SQLDataType.INTEGER.asConvertedDataType(binding).getArrayDataType();

 // Works
 DataTypeinvalid input: '<'UserType[]> t2 =
   SQLDataType.INTEGER.getArrayDataType().asConvertedDataType(arrayBinding);
 

Throws:

DataTypeException - When this data type has a custom getBinding(), which cannot be automatically translated to an array Binding.

asConvertedDataTypeFrom

@NotNull
default <U> @NotNull DataType<U> asConvertedDataTypeFrom(Function<? super T,? extends U> from)

Convenience method for converting this type to a read-only type using Converter.from(Class, Class, Function).

Unlike asConvertedDataTypeFrom(Class, Function), this method attempts to work without an explicit Class reference for the underlying Converter.toType(). There may be some edge cases where this doesn't work (e.g. when arrays are involved), in case of which, an explicit class literal should be passed.

asConvertedDataTypeTo

@NotNull
default <U> @NotNull DataType<U> asConvertedDataTypeTo(Class<U> toType,

getCastTypeName

@NotNull
@NotNull String getCastTypeName(Configuration configuration)

Retrieve the dialect-specific type name associated with this data type used for casting.

This is useful for some dialects that have specialised type names for cast expressions. Other dialects require type-length binding when casting, (e.g. VARCHAR(32767))

getDialect

@Nullable
@Nullable SQLDialect getDialect()

Retrieve the underlying SQLDialect.

convert

@Deprecated(forRemoval=true)
T convert(Object object)

Deprecated, for removal: This API element is subject to removal in a future version.

- 3.20.0 - [#16810] - Static data type conversion has been a controversial historic feature of jOOQ. While occasionally useful for internal data types (such as String to Integer conversion, etc.) it doesn't work well with user defined types. 1) This method does not go through Configuration.converterProvider(), 2) nor does it provide an appropriate ConverterContext to a ContextConverter, leading to subtle bugs. 3) It also doesn't make any guarantees related to what user defined types can be passed to it. This is why this method is deprecated and will be removed in a future jOOQ version. Use getConverter() on this type, instead, and use that for data type conversions.

readonly

boolean readonly()

Get the readonly attribute of this data type.

This feature is implemented in commercial distributions only.

readonlyInternal

boolean readonlyInternal()

Get the readonly attribute of this data type, combined with other flags that influence readonly behaviour.

A column may be marked as readonly() for various reasons, including:

• When it is marked as readonly explicitly by the code generator.
• When it is marked as readonly implicitly because it's a computed column with QOM.GenerationLocation.SERVER or with QOM.GenerationLocation.CLIENT and QOM.GenerationOption.VIRTUAL.

Some columns are readonly for users, meaning users of the jOOQ API cannot write to them, but jOOQ, internally, may still write to those columns. Such columns may include:

• Columns that are computed with QOM.GenerationLocation.CLIENT and QOM.GenerationOption.STORED
• Columns used for optimistic locking

This method returns the static information for this data type. The information may be overridden by a Settings value, e.g. Settings.isEmulateComputedColumns(), in case of which readonlyInternal(Configuration) should be called.

This feature is implemented in commercial distributions only.

Whether this column is computed on the client.

This is true only if all of these hold true:

• computed()
• generationLocation() == QOM.GenerationLocation.CLIENT

computedOnClientStoredOn

boolean computedOnClientStoredOn(GeneratorStatementType statementType)

@NotNull DataType<T> generatedAlwaysAs(T generatedAlwaysAsValue)

Set the computed column expression of this data type to a constant value.

This implicitly sets readonly() to true.

This feature is implemented in commercial distributions only.

generatedAlwaysAs

@NotNull
@Support({AURORA_POSTGRES,CLICKHOUSE,COCKROACHDB,DB2,DERBY,DUCKDB,FIREBIRD,H2,HANA,HSQLDB,MARIADB,MYSQL_5_7,ORACLE12C,POSTGRES_12,SQLSERVER})
@NotNull DataType<T> generatedAlwaysAs(Field<T> generatedAlwaysAsValue)

Set the computed column expression of this data type to a constant expression.

This implicitly sets readonly() to true.

This feature is implemented in commercial distributions only.

generatedAlwaysAs

@NotNull
@NotNull DataType<T> generatedAlwaysAs(Generator<?,?,T> generatedAlwaysAsValue)

Set the computed column expression of this data type to a dynamic expression.

Unlike generatedAlwaysAs(Object) and generatedAlwaysAs(Field), which produce a constant value or expression, this allows for generating a dynamic expression if used along with generationLocation() and QOM.GenerationLocation.CLIENT, in order to implement client side computed columns.

If generationLocation() is QOM.GenerationLocation.SERVER, then this does not affect generated DML statements, and will be evaluated only in DDL statements, when creating the table.

This implicitly sets readonly() to true.

This feature is implemented in commercial distributions only.

generatedAlwaysAs

@Nullable
@Nullable Field<T> generatedAlwaysAs()

Get the computed column expression of this data type, if any.

This eagerly evaluates the generatedAlwaysAsGenerator() generator, which may not produce the same expression upon execution of a query, in case generationLocation() is QOM.GenerationLocation.CLIENT. The behaviour of QOM.GenerationLocation.SERVER is not affected. The method has been left unmodified for backwards compatibility with jOOQ 3.16.

This feature is implemented in commercial distributions only.

@NotNull DataType<T> generationOption(QOM.GenerationOption generationOption)

Set the generationOption() of the computed column expression.

If not supported by the dialect, this will be ignored.

This feature is implemented in commercial distributions only.

generationOption

@NotNull
@Support

This feature is implemented in commercial distributions only.

generationLocation

@NotNull
@Support
@NotNull DataType<T> generationLocation(QOM.GenerationLocation generationOption)

Set the generationLocation() of the computed column expression.

Specifies whether the generatedAlwaysAs() expression is computed on the QOM.GenerationLocation.SERVER (by default) or in the QOM.GenerationLocation.CLIENT. The latter is supported in all dialects, the former only in relevant dialects.

The computation happens in Insert, Update, or Merge statements in case generationOption() is QOM.GenerationOption.STORED, or in Select in case the generationOption() is QOM.GenerationOption.VIRTUAL.

This feature is implemented in commercial distributions only.

Get the QOM.GenerationLocation of the computed column expression of this data type, if any.

Specifies whether the generatedAlwaysAs() expression is computed on the QOM.GenerationLocation.SERVER (by default) or in the QOM.GenerationLocation.CLIENT. The latter is supported in all dialects, the former only in relevant dialects.

The type may still be usable with the jOOQ API, but jOOQ's behaviour may not be well defined. Please note that any future minor release may add support for a vendor specific type, meaning the type loses its "otherness."
