This feature will be removed in a future version of Microsoft SQL Server. Avoid using this feature in new development work, and plan to modify applications that currently use this feature.
The InsertColumn method adds a column to the Columns collection of a Table object at the position indicated.
Use the InsertColumn method when the ordinal position of a column must be maintained.
Columns in existing Microsoft SQL Server tables have fixed ordinal location. You cannot use the InsertColumn method when the Table object references an existing SQL Server table. Use InsertColumn only when the Table object is used to create a SQL Server table.
