Annotation Type Require

@Target(value={METHOD,CONSTRUCTOR,TYPE,PACKAGE})
 @Retention(value=RUNTIME)
 @Documented
 @Inherited
public @interface Require

Require a set of SQLDialect to be supported by any jOOQ statement in the scope of this annotation.

This annotation can be used at the use-site of jOOQ API at any given scope ElementType.PACKAGE, ElementType.TYPE, ElementType.METHOD in order to specify that the given scope requires ALL of the supplied SQLDialect to be supported by all usage of jOOQ API within the scope. For example:

 // Allow only MYSQL or ORACLE dialect support to be used within the class scope
 @Allow(MYSQL, ORACLE)
 public class MySQLAndOracleDAO {

     // Allow rule from class applies to this method
     public void mysqlAndOracleMethod() {
         DSL.using(configuration)
            .insertInto(TABLE, TABLE.COLUMN)
            .values(1)
            // This type checks as it works on both MySQL and Oracle
            .onDuplicateKeyUpdate()
            .set(TABLE.COLUMN, 2)
            .execute();
     }

     // Refine class Allow rule with additional requirement
     @Require(ORACLE)
     public void oracleOnlyMethod() {
         DSL.using(configuration)
            .mergeInto(TABLE)
            .using(selectOne())
            .on(TABLE.COLUMN.eq(1))
            .whenMatchedThenUpdate()
            .set(TABLE.COLUMN, 2)
            .whenNotMatchedThenInsert(TABLE.COLUMN)
            .values(1)
            .execute();
     }
 }
 

Type checking for these annotations can be supplied by org.jooq.checker.SQLDialectChecker from the jOOQ-checker module.

Type checking for these annotations can be supplied by org.jooq.checker.SQLDialectChecker from the jOOQ-checker module.

Rules:

• In the absence of any Allow annotation, no jOOQ API usage is allowed.
• The combination of all Allow annotations and of the inner-most Require annotation is applied for any given scope.
• Nested packages are not creating nested scopes.
• If a versioned SQLDialect is required (rather than a SQLDialect.family()), then the required version, any of its SQLDialect.predecessor(), or its SQLDialect.family() are required.
