[jira] [Created] (DERBY-6476) Allow derived column lists in MERGE
statements.
Rick Hillegas created DERBY-6476:
------------------------------------
Summary: Allow derived column lists in MERGE statements.
Key: DERBY-6476
URL: https://issues.apache.org/jira/browse/DERBY-6476
Project: Derby
Issue Type: Improvement
Components: SQL
Affects Versions: 10.11.0.0
Reporter: Rick Hillegas
Priority: Minor
Derby does not allow derived column lists aliased to the source or target tables in MERGE statement. So, the following statements are not allowed:
{noformat}
merge into t1_036 r( x )
using t2_036 on r.x = t2_036.a
when matched then delete;
merge into t1_036
using t2_036 r( x ) on t1_036.a = r.x
when matched then delete;
{noformat}
Problems with these derived column lists were noted by Knut in a 2014-02-07 comment on DERBY-3155.
