Subject [jira] [Created] (DERBY-5825) Catch type mismatch of DEFAULT values at DDL time
Date Thu, 21 Jun 2012 16:33:42 GMT
Dag H. Wanvik created DERBY-5825:
------------------------------------

             Summary: Catch type mismatch of DEFAULT values at DDL time
                 Key: DERBY-5825
                 URL: https://issues.apache.org/jira/browse/DERBY-5825
             Project: Derby
          Issue Type: Bug
          Components: SQL
            Reporter: Dag H. Wanvik


Derby postpones checking values in DEFAULT clauses to DML time, cf this example:

  create table t(c varchar(2) default 'foo')
  insert into t values default

According to the standard [1], an error should result at create table
time. Derby throws an error only at insert time above. Similarly for
other types. Cf also discussion in DERBY-118. 

We should implement correct type checking of the DEFAULT values given
at DDL time.
