GetColumnID method

Returns the column ID of the named column.

Visual Basic
Public Function GetColumnID( _
   ByVal name As String _
) As Short
public short GetColumnID(
   string  name
  • name   The name of the column.

Return value

The column ID of the named column.


Column IDs range from 0 to ColumnCount-1, inclusive.

Note that in result sets, not all columns have names and not all column names are unique. If you are not using aliases, the name of a non-computed column is prefixed with the name of the table the column is from. For example, MyTable.ID is the name of the only column in the result set for the query "SELECT ID FROM MyTable".

Column IDs and counts might change during a schema upgrade. To correctly identify a column, access it by name or refresh the cached IDs and counts after a schema upgrade.
