error:

 [ibm][cli driver][db2/aix64] sql0811n  result of scalar fullselect, select    statement, or values statement more 1 row.  sqlstate=21000

the error message pretty self-explanatory. 1 of sub-selects returning more 1 row back, , database doesn't know how handle that. i'm guessing database db2 on linux/unix/windows, based on error message, here's info center article on error.
