IT32989: UNQUALIFIED COLUMN REFERENCE WITH USING CLAUSE ON VIEW RETURNS SQLCODE=-206

Db2 Version 11.1 Mod 4 Fix Pack 7 for Linux, UNIX, and Windows

APAR status

• Closed as program error.

Error description

• A query as follows can fail with an SQL0206N error:
  
  SELECT TABSCHEMA , TABNAME , COLNAME FROM SYSCAT.TABLES JOIN
  SYSCAT.COLUMNS USING (TABSCHEMA, TABNAME) WHERE (TABSCHEMA,
  TABNAME) IN (SELECT TABSCHEMA, TABNAME FROM SYSCAT.INDEXES)
  
  SQL0206N "TABSCHEMA" is not valid in the context where it is
  used.
  SQLSTATE=42703
  

Local fix

• Explicitly qualify the columns in the VIEW.
  
  For example:
  SELECT t.TABSCHEMA, t.TABNAME, c.COLNAME FROM SYSCAT.TABLES t
  JOIN SYSCAT.COLUMNS c USING (TABSCHEMA, TABNAME) WHERE
  (t.TABSCHEMA, t.TABNAME) IN (SELECT TABSCHEMA, TABNAME FROM
  SYSCAT.INDEXES)
