Changing table properties

Hi,
I have got approximately 100 tables. Their all attributes are same. But, I w
ant to change their one attribute.
Such as my table;
NAME nvarchar(50)
SNAME nvarchar(50)
SALARY float
I want to change SALARY's property from float to money. It is possible to th
is operation manually. But I need to this operation automaticallay via progr
amming language or via query analizer.
How can I do?Why would you want 100 identical tables? How about combining them into one.
If you have no choice but to support the current design then use a query out
of INFORMATION_SCHEMA.TABLES to generate the script.
SELECT 'ALTER TABLE '+
QUOTENAME(table_schema)+'.'+
QUOTENAME(table_name)+' ALTER COLUMN salary DECIMAL(10,2)'
FROM information_schema.tables
WHERE table_name LIKE ?
Now just cut and paste the results into Query Analyzer.
I recommend you avoid using MONEY for the salary column because MONEY has
some problems with precision in arithmetic operations. Use DECIMAL/NUMERIC
instead.

--|||Hi
I would do it slightly differently!!!
SELECT 'ALTER TABLE '+
QUOTENAME(table_schema)+'.'+
QUOTENAME(table_name)+' ALTER COLUMN ' + QUOTENAME(COLUMN_NAME) + '
DECIMAL(10,2)'
FROM information_schema.columns
WHERE COLUMN_NAME = 'Salary'
