This is what I want to do:
1. Delete all tables in database with table names that ends with a
number.
2. Leave all other tables in tact.
3. Table names are unknown.
4. Numbers attached to table names are unknown.
5. Unknown number of tables in database.
For example:
(Tables in database)
Account
Account1
Account2
Binder
Binder1
Binder2
Binder3
.......
I want to delete all the tables in the database with the exception
of Account and Binder.
I know that there are no wildcards in the "Drop Table tablename"
syntax. Does anyone have any suggestions on how to write this sql
statement?
Note: I am executing this statement in MS Access with the
"DoCmd.RunS QL sql_statement" command.
Thanks for any help! 2 8672

The simplest way is to say:
SELECT 'DROP TABLE ' + name FROM sysobjects WHERE name LIKE '%[0-9]'
and then cut and paste and run the result. You would do this from
Query Analyzer.
If you would like to do it programmaticall y, because you are doing
it routinely, you could set up a cursor over sysobjects, and then
use dynamic SQL to drop the tables:
DECLARE @tbl sysname
DECLARE drop_tbl_cur INSENSITIVE CURSOR FOR
SELECT name FROM sysobjects WHERE name like '%[0-9]'
OPEN CURSOR drop_tbl_cur
WHILE 1 = 1
BEGIN
FETCH drop_tbl_cur INTO @tbl
IF @@fetch_status <> 0
BREAK
EXEC ('DROP TABLE ' + @tbl)
END
DEALLOCATE drop_tbl_cur

I would also add ' AND xtype = 'U' ' in the where statement so that it
includes only user tables. This way it would include any object in the
statement and you would get errors when trying to execute.
it would look something like this:
SELECT 'DROP TABLE ' + name FROM sysobjects WHERE name LIKE '%[0-9] and
xtype = 'U'

Hi,
* Question background :
My DB is in ArchiveLog mode.
I have TS in ReadOnly mode.
As i know,
- Oracle allows to DROP table resides in ReadOnly TS (& other objects
also) even though that TS is in ReadOnly mode.
- Oracle will not recover ReadOnly TS during Oracle startup.

Hi. Thru a sproc, I drop & re-create some temp tables.
When I call that sproc from the client, though, I cannot drop the

I need to allow the user, say "Alex", to drop/create tables (actually,
that would be DDL). Which role should "Alex" assume ? How do I do that
?
I run the following sproc named, say, "CREATE_TABLE" (SNIP):

Hi,
I am using Q Replication, I need to set to logging to capture changes on a
table but the table has more than 18 characters for the name, I looked at
the docs, it mentioned that table names with more than 18 characters are
allowed in DB2 V8 but when you turn on logging, it will not turn on logging.
Is there a work around to this?
Thanks

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
