BUG# 15615 (6.50) (sqlserver)

SYMPTOMS

INSERTing to a table from a UNION of two or more SELECTs may result in a handled access violation if one of the SELECTs statements generates error 512.

On the client side, the application will receive the following error:

   Msg 512, Level 16, State 1
   Subquery returned more than 1 value.  The is illegal when the subquery
   follows =, !=, <. <=, >, >=, or when the subquery is used as an
   expression.

   DB-Library Process Dead - Connection Broken.

WORKAROUND

Correct the subquery so that it will only return only one value.

STATUS
