如何检查SQL Server 2005中是否存在非聚簇索引

Question

我有以下内容:

CREATE NONCLUSTERED INDEX [MyTableIndex]
ON [dbo].[tablename] ([tablename_ID],[tablename_Field1])
INCLUDE ([Tablename_Field2],[Tablename_Field3])

我想创建一个if语句来检查它是否存在.我该怎么做呢？

Answer 1

IF NOT EXISTS(SELECT * FROM sys.indexes WHERE name = 'MyTableIndex' AND object_id = OBJECT_ID('tablename'))
    BEGIN
        -- Index with this name, on this table does NOT exist
    END

Answer 2

试试这个:

IF NOT EXISTS(SELECT * FROM sys.indexes WHERE Name = 'MyTableIndex')
   -- put your CREATE INDEX statement here
