generatedAlwaysAs

public final DataType<T> generatedAlwaysAs(Generator<?,?,T> g)

Beschreibung aus Schnittstelle kopiert: DataType

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

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

If DataType.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 DataType.readonly() to true.

This feature is implemented in commercial distributions only.

Angegeben von:

generatedAlwaysAs in Schnittstelle DataType<T>

generationOption

public final DataType<T> generationOption(QOM.GenerationOption g)

Beschreibung aus Schnittstelle kopiert: DataType

Specifies whether the DataType.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 DataType.generationOption() is QOM.GenerationOption.STORED, or in Select in case the DataType.generationOption() is QOM.GenerationOption.VIRTUAL.

Gibt zurück:

The new data type

default_

public final DataType<T> default_(Field<T> d)

Angegeben von:

notNull in Schnittstelle DataType<T>

readonlyInternal

public final boolean readonlyInternal()

Beschreibung aus Schnittstelle kopiert: DataType

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

A column may be marked as DataType.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 feature is implemented in commercial distributions only.

toString

public String toString()

Beschreibung aus Schnittstelle kopiert: QueryPart

Render a SQL string representation of this QueryPart.

For improved debugging, this renders a SQL string of this QueryPart with inlined bind variables. If this QueryPart is Attachable, then the attached Configuration may be used for rendering the SQL string, including SQLDialect and Settings. Do note that most QueryPart instances are not attached to a Configuration, and thus there is no guarantee that the SQL string will make sense in the context of a specific database.

Angegeben von:

toString in Schnittstelle QueryPart

Gibt zurück:

A SQL string representation of this QueryPart

hashCode

public int hashCode()

Beschreibung aus Schnittstelle kopiert: QueryPart

Generate a hash code from this QueryPart.

In general, QueryPart hash codes are the same as the hash codes generated from QueryPart.toString(). This guarantees consistent behaviour with QueryPart.equals(Object)

Some QueryPart implementations may choose to override this behaviour for improved performance, as QueryPart.toString() is an expensive operation, if called many times.

Angegeben von:

hashCode in Schnittstelle QueryPart

Gibt zurück:

The QueryPart hash code

equals

public boolean equals(Object obj)

Beschreibung aus Schnittstelle kopiert: QueryPart

Check whether this QueryPart can be considered equal to another QueryPart.

In general, QueryPart equality is defined in terms of QueryPart.toString() equality. In other words, two query parts are considered equal if their rendered SQL (with inlined bind variables) is equal. This means that the two query parts do not necessarily have to be of the same type.

Some QueryPart implementations may choose to override this behaviour for improved performance, as QueryPart.toString() is an expensive operation, if called many times.

Angegeben von:

equals in Schnittstelle QueryPart

Parameter:

obj - The other QueryPart

Gibt zurück:

Whether the two query parts are equal
