Annotation Type Support

@Target(value={METHOD,FIELD})
 @Retention(value=RUNTIME)
 @Documented
 @Inherited
public @interface Support

A formal declaration of whether any API element is supported by a given SQLDialect

The annotation is mainly used in three modes:

• The annotation is absent on a method. This means that the applied SQLDialect is irrelevant for that method. This is mostly the case for jOOQ's general API (creating factories, rendering SQL, binding variables, etc.) as well as utility methods.
• The annotation is present but "empty" on a method, i.e. it specifies no SQLDialect. This means that all of jOOQ's dialects are supported by this API method. This is typically the case with jOOQ's SQL construction API for very common clauses, such as the creation of SELECT, UPDATE, INSERT, DELETE.
• The annotation is present and specifies one or more dialects. A method annotated in such a way should be used only along with any of the dialects specified by the annotation. This is typically the case with jOOQ's SQL construction API for less common clauses, such as the creation of MERGE, etc.

  There listed dialects can be either a:

  • A dialect family, in case of which all versions of the family support the feature. E.g. when SQLDialect.POSTGRES is referenced, then SQLDialect.POSTGRES_9_3, SQLDialect.POSTGRES_9_4, etc. support the feature as well
  • A dialect version, in case of which all versions larger or equal than the referenced version support the feature. E.g. when SQLDialect.POSTGRES_9_4 is referenced, then SQLDialect.POSTGRES_9_5 would support the feature as well, but not SQLDialect.POSTGRES_9_3

Future versions of jOOQ may use these annotations for throwing SQLDialectNotSupportedException where appropriate, or preprocessing jOOQ source code in order to mark unsupported API as Deprecated
