ALTER INDEX IF EXISTS

Applies to ✅ Open Source Edition   ✅ Express Edition   ✅ Professional Edition   ✅ Enterprise Edition

A popular subclause of DDL statements that jOOQ can usually emulate, is the IF EXISTS clause:

// Renaming the index
create.alterIndexIfExists("old_index").renameTo("new_index").execute();

Dialect support

This example using jOOQ:

alterIndexIfExists("i").renameTo("j")

Translates to the following dialect specific expressions:
