如果列存在于表中，则重命名该列

Question

我正在尝试重命名列（如果存在）

GO

IF EXISTS(SELECT 1 FROM sys.columns WHERE [name] = N'MinDuration'
           AND [object_id] = OBJECT_ID(N'Category'))
BEGIN
    sp_RENAME 'Category.MinDuration', 'SingleDuration' , 'COLUMN'
END

GO

但是收到错误Incorrect syntax near sp_RENAME. Expecting CONVERSATION, DIALOG, DISTRIBUTED or TRANSACTION

如果我的列存在于表中，如何重命名列？

Answer 1

首先尝试exec：

IF EXISTS(SELECT 1 FROM sys.columns WHERE [name] = N'MinDuration'
           AND [object_id] = OBJECT_ID(N'Category'))
BEGIN
    EXEC sp_RENAME 'Category.MinDuration', 'SingleDuration' , 'COLUMN'
END;
