Hello,
I have test it now. stmtxt = 'select 1 from rdb$database where exists(SELECT * FROM RDB$RELATION_FIELDS WHERE RDB$RELATION_NAME = T_DT and RDB$FIELD_NAME = ''''' || fname || ''''''; execute statement stmtxt into :idexists; The stmtxt is '..._Name = '''COLUMNAME'''' and I get an SQL-Error. The statement-text should be '..._Name = 'COLUMNNAME''. I will test a little bit tomorrow. Thanks for helping. Regards. Olaf [Non-text portions of this message have been removed]
