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
