In Configuration Manager 2007, the ColumnName (SqlQueryDiscoveryType) element is the name of the column whose values will be retrieved from the result set that is returned in the Query. This can be case sensitive depending upon the case sensitivity of the instance of SQL Server that is being connected to.
The ColumnName element is defined by the SqlQueryDiscoveryType complex type.
<xs:element name="ColumnName" type="NonEmptyStringType" />
