Problem Note 32085: Incorrect SQL optimization may produce incorrect results
 |  |  |  |  |
In rare cases, an incorrect optimization of an SQL query may produce incorrect results. This problem occurs only when one or more variables are keys in an index created with the UNIQUE option.
To circumvent this problem, set the SPDSTCNT= macro variable or the THREADNUM= data set option to 1.
