Hello,
I want to change the datatype of a field from Varchar to integer in T-SQL.
I tried something like Modify like you use in Oracle.
ALTER TABLE tablename
MODIFY COLUMNNAME Datatype.
But its not working in SQL server..
Any thoughts.

G'd evening!
In case you still need to change the table's column type from T-SQL , the sintax for MS SQL is:
ALTER TABLE table ALTER COLUMN column_name new_data_type
Ex.
ALTER TABLE MyTable ALTER COLUMN MyColumn NVARCHAR(20)
For more about the Alter Table sintax, read the books on line (BOL), here is the last update for SQL 2k SQL Server Books Online January 2004 Update
Good luck
Estuardo
