Cesar,
You need to build the index also, try BUILD.INDEX FILNAME ALL
In Unidata that is.

I think we will need more information to help you.
1. are you running the SQL query at TCL or through ODBC or OleDB?
César: I running the SQL query at TCL
2. Can you give the command you are running please.
Cesar: SELECT PEDIDO,REFART,DESART,CANTIDAD,CANTMODALB FROM GCMLIAL WHERE
EMPALBA = '1*05236' ORDER BY EMP, ALBA, NUMLIN;
Cesar: SELECT PEDIDO, SUREF FROM GCMLIAL WHERE EMPALBA = '1*05236' GROUP
BY PEDIDO, SUREF;
3. Are there any indexes on the files? (LIST.INDEX filename ALL)
Cesar: There aren't indexes on the files, I create index but the result
is the same.
Regards,
Brian Leach

Subject: [UV] Very slow SQL query
Hello,
I have two files one has 300.000 records and another has 200.000
records, I wante to make SQL Query whit the two files and this takes bettewn
30 seconds and 1 minute to return the result.
However, I have a program with BASIC to obtime the same result and it
takes less than one second, I have heard that other DB Systems like SQL
Server, Oracle, etc... are very fast with the SQL Query.
Is this posible or do have I made a mistake?
Thanks
César
