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:
