Problembeschreibung: | |
Dropping a column using the ALTER TABLE command fails with SQL0478N if the database configuration parameter AUTO_REVAL is set to DEFERRED. Reproduction scenario: $ db2 "create table t1 (c1 int ,c2 int)" DB20000I The SQL command completed successfully. $ db2 "create index ixt1 on t1(c1,c2)" DB20000I The SQL command completed successfully. $ db2 "alter table t1 drop column c2" DB21034E The command was processed as an SQL statement because it was not a valid Command Line Processor command. During SQL processing it returned: SQL0478N DROP, ALTER, TRANSFER OWNERSHIP or REVOKE on object type "COLUMN" cannot be processed because there is an object "IXT1", of type "INDEX", which depends on it. SQLSTATE=42893 | |
