ALTER TABLE .. ADD CHECK

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

All constraint types can be added with the ALTER TABLE statement. This includes CHECK constraints:

// Adding an unnamed constraint to a table
create.alterTable("table").add(check(length(field(name("c"), INTEGER)).gt(0))).execute();

// Adding a named constraint to a table
create.alterTable("table").add(constraint("ck").check(length(field(name("c"), INTEGER)).gt(0))).execute();
It is recommended to always provide a name with a constraint to simplify schema management. See also this section of the manual
