ObjName ) as String

Parts

object

Expression that evaluates to an object in the Applies To list

Row

Long integer that identifies a row by ordinal position

Column

Long integer that identifies a column by ordinal position

Prototype (C/C++)

HRESULT GetColumnSQLVARIANTDataType(
long lRow,
long lColumn,
SQLDMO_LPCSTR ObjName,
SQLDMO_LPBSTR pRetVal);

Note  SQL-DMO strings are returned as OLE BSTR objects. A C/C++ application obtains a reference to the string. The application must release the reference using SysFreeString.

Remarks

An application written in C++ can use the information returned by the GetColumnSQLVARIANTDataType and GetColumnSQLVARIANTLength methods to allocate an appropriate amount of buffer space in which to manipulate the data retrieved from a sql_variant column.

The application can then call GetColumnSQLVARIANT to return the contents of a sql_variant column as an array. The application can then cast the contents of the array into the required data type.

Note  If an application calls GetColumnSQLVARIANTDataType on an instance of SQL Server version 7.0, the constant, SQLDMO_E_SQL80ONLY, and the message "This property or method requires Microsoft SQL Server 2000" are returned.
