The unknown symbol '' $01
Posted: Mon 24 Jul 2006 20:58
Hello,
i use Delphi4 (Upd3) with SDAC-Components for MS-SQL.
By using the Query-Component i have this Error:
This is the Source
The Variable BS_ID is String and RZ.zeitraum_id is Integer with valid values.
The Problem ist, that the Error comes some times, but the most times the SQL-Script works fine.
Greetings

ps: sorry about my english. My 2nd language is Pascal
