Neither. I was talking about manipualating objects (i.e., CREATE TABLE), not creating recordsets or manipulating data.

If you are selecting or updating data, then DAO and ADO are comparable to DML. Which is your discussion about? Charles Wortz Software Development Division Texas Education Agency 1701 N.

When access an MDB via code, DAO is always faster, but ADO is more suitable if you will also be tapping into other data stores such as SQL Server or Oracle. In reguards to database bloat, an MDB will bloat because of the required database space to store a temporary file be it sql or code. IF you mean SQL as in SQL Server, then the advantages are many, but one that comes to mind is the tempdb which is very useful because it holds all the data temorarily when using groupby's or order by's in your SQL code, of course you can't access this via DAO unless of course you have the table linked to a MDB. -Francisco http://rcm.netfirms.com On Monday, March 31, 2003 9:26 AM [GMT-8], Susan Harkins <harkins at iglou.com> wrote: : Charlotte and I are having a brief discussion off list of how SQL can : solve some bloat problems.
