ALTER SEQUENCE 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 schema
create.alterSequenceIfExists("old_sequence").renameTo("new_sequence").execute();

This example using jOOQ:
alterSequenceIfExists("s").renameTo("t")
Translates to the following dialect specific expressions:

ALTER TABLE s RENAME TO t
