Hi All,
I have a Table called Table1, in that I have a column called Status which is of type Varchar and contains values link '1', '2', '3' etc, i.e. all integer values only but in Varchar type.
I need to change this column's datatype to Integer for some reason, any idea how do we do it ?
I am trying like:
ALTER TABLE Table1 ALTER STATUS TYPE Integer;
But I am getting an error like, "Cannot change datatype......."
Thanks In Advance.
With Best Regards.
