Annotation Type LibraryOperator

@Retention(value=RUNTIME)
 @Target(value=FIELD)
public @interface LibraryOperator

An annotation that is read by SqlLibraryOperatorTableFactory to add functions and operators to a library.

Typically, such collections are associated with a particular dialect or database. For example, SqlLibrary.ORACLE is a collection of functions that are in the Oracle database but not the SQL standard.

In SqlLibraryOperatorTableFactory this annotation is applied to function definitions to include them in a particular library. It allows an operator to belong to more than one library.
