Have an eye on this about irev <=> postgreSQL production state design skills :

> && "WHERE module_name = '" & tparam1 & "'" into sqlStatement
> put revQueryDatabase(myDatabaseID,sqlStatement) into
> dbCursorID
> if dbCursorID is not a number
> then return the result
> else

> put

> if nModuleState is in "NY" then
>
> if nModuleState is "Y"
> then put "N" into nModuleState
> else if nModuleState is "N"
> then put "Y" into nModuleState
> put "UPDATE" && CustModules && "SET
> activation = '" & nModuleState & "' WHERE module_name = '" & tparam1 & "'"
> into sqlStatement2
> revExecuteSQL myDatabaseID,sqlStatement2
> if the result is not a number

each "then return the result" will expose the original postgreSQL error message
