ALTER TABLE that renames columns and CHECK constraints

    XMLWordPrintable

    Details

      Description

      If a column is renamed, CHECK constraint isn't changed to use the new column name. But UNIQUE constraint is.

      create table t1 (a int, b int, check(a>b));
      alter table t1 change column a b int, change column b a int;
      show create table t1;
      

      Compare with

      create table t1 (a int, b int, unique(a,b));
      alter table t1 change column a b int, change column b a int;
      show create table t1;
