ORA-06550

[2006-01-10 11:58:28:702] [DoRequest] [PUASOWI] [service-j2ee-2] [java.sql.SQLException: ORA-06550: line 1, column 188:PLS-00103: Encountered the symbol "S" when expecting one of the following:

. ( ) , * @ % & = - + < / > at in is mod not range rem =>
.. <> or != or ~= >= <= <> and or like between

This thing has been bugging me, since late last year.
If ever you encounter such error, check if the values you'd like to insert are properly quoted. ( ", ' )
Irritating, pero now I know! hehehe..
