I have:
ALTER TABLE [tblName]
Modify [clmName] to [clmName] format 999.9;
Something is wrong.... I'm kind of new to this. Could any help me
with the correct syntax?
thanks,
ori

I would suggest checking out ALTER TABLE in Books Online, however something
like this may be what you need:
ALTER TABLE <TblName> ALTER COLUMN <ClmName> VARCHAR(5) NOT NULL
CONSTRAINT <ConName> CHECK <ClmName> LIKE '[0-9][0-9][0-9].[0-9]'
I am assuming you want three digits, then a decimal point, then another
digit. If not then change the LIKE clause to suit your needs. The syntax
might not be spot on so I suggest you read up in BOL.

1. multiple ALTER COLUMNs in one ALTER TABLE statement?
Hello,
I am afraid the answer is no but is there a way to do something like this:
ALTER TABLE mytable
ALTER COLUMN col1 int,
col2 float
I am taking a database that has been created by an upsizing wizard from
Visual FoxPro and all the numerics are set to float in SQL Server and I want
to use varchar on longer text fields (I'll ask about that in another post).
since many of the tables have 10 or more fields that need changing I just
used Enterprise Manager to Generate SQL for the database and used my text
editor to change the column values and change from CREATE to ALTER.
What I have now is a script with a lot of ALTER TABLEs that look like the
above but Query Analyzer is not liking it.
Thanks, Tom
