GenerateCreationSQL Method
后续版本的 Microsoft SQL Server 将删除该功能。 请避免在新的开发工作中使用该功能,并着手修改当前还在使用该功能的应用程序。
The GenerateCreationSQL method returns a string that contains a Transact-SQL command batch used to create the Microsoft SQL Server index defined by the properties of the Index object used.
语法
object.GenerateCreationSQL(Table)asString
Parts
object
Expression that evaluates to an object in the Applies To list.Table
Expression that evaluates to a SQL Distributed Management Objects (SQL-DMO) Table object.
Prototype (C/C++)
HRESULT GenerateCreationSQL(
LPSQLDMOTABLE TargetTable,
SQLDMO_LPBSTR Messages);
![]() |
---|
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 Transact-SQL command batch as a string.
注释
The Index object exposes the GenerateSQL and GenerateCreationSQL methods. Both methods generate a command batch that creates an index. However, the Transact-SQL command batch returned by the GenerateCreationSQL method prefixes an index creation statement with a statement conditionally dropping the index.
For more information about using the GenerateSQL and GenerateCreationSQL methods, see GenerateSQL Method (Index).
