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. |
Comentários
The Datatype property may not completely define the data type of a column. Columns requiring width specification, such as varchar, or specification of scale and precision, such as decimal, are defined using the Datatype property in concert with Length, NumericPrecision, and NumericScale properties.
Use the AlterDataType method to change the data type of an existing column.
