如何检查 SQL Server 2005 中是否存在非聚集索引

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？

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
