ALTER TABLE .. DROP COLUMN RESTRICT

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

An optional RESTRICT clause can be added to a DROP COLUMN clause to hint at the operation failing when there are objects depending on the column.

// Add a RESTRICT clause when dropping columns
create.alterTable("table").drop("column").restrict().execute();

In most RDBMS, RESTRICT semantics is the default when dropping columns, although implementations do not agree on what dependent objects are included in the RESTRICT check.
