---|
SQL Distributed Management Objects (SQL-DMO) strings are always returned as OLE BSTR objects. A C/C++ application obtains a reference to the string. The application must release the reference using SysFreeString. |
Returns
A String representation of the value of a QueryResults result set member.
備註
When converting a value of any data type to string, conversion rules are those applied for the locale of the client workstation.
The Row and Column Parameters are 1-based in Visual Basic applications, and are zero-based in C++ applications.
