創建非集羣列存儲索引的存儲過程

Question

我需要一個存儲過程，它將接受表名作爲參數，然後在每列上創建非集羣列存儲索引。

有人可以幫助我嗎？

CREATE NONCLUSTERED COLUMNSTORE INDEX XCSI_MY_TBL 
ON dbo.MY_TBL 
( 
    COL1, 
    COL2, 
    COL3, 
    COL4 
) WITH (DROP_EXISTING = OFF) ON [PRIMARY] 

Answer 1

我想我設法找到了解決方案。

CREATE PROC [dbo].[CRE_NCCS_IDX] @TBL_NM VARCHAR(100) AS 
BEGIN 

--DECLARING VARIABLES FOR DYNAMIC SQL 
DECLARE @TBL TABLE(ID INT, TBL_NM VARCHAR(100), CLMN_NM VARCHAR(100)) 
DECLARE @COL_VAL NVARCHAR(4000) 
DECLARE @SEL_SQL NVARCHAR(4000) 
DECLARE @DROP_SQL VARCHAR(1000) 

--INSERTING INTO TEMP TABLE 
INSERT INTO @TBL 
SELECT ROW_NUMBER() OVER(PARTITION BY COLUMN_NAME ORDER BY COLUMN_NAME) AS ID, 
    TABLE_NAME, 
    COLUMN_NAME 
FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = @TBL_NM 

--GETTING COLUMN VALUES AS COMMA SEPERATED STRING 
SET @COL_VAL = (
SELECT STUFF((SELECT ', ' + CAST(CLMN_NM AS VARCHAR(1000)) [text()] 
     FROM @TBL 
     WHERE ID = t.ID 
     FOR XML PATH(''), TYPE) 
     .value('.','NVARCHAR(MAX)'),1,2,' ') List_Output 
FROM @TBL t 
GROUP BY ID 
) 

--DROPPING INDEX IF EXISTS 
SET @DROP_SQL = CONCAT('IF EXISTS(SELECT * FROM SYS.INDEXES WHERE OBJECT_ID = OBJECT_ID(''', @TBL_NM, ''') AND NAME =''XCSI_', @TBL_NM, 
          ''') DROP INDEX XCSI_', @TBL_NM, ' ON dbo.', @TBL_NM) 

EXEC (@DROP_SQL) 

--EXECUTING DYNAMIC SQL FOR CREATING INDEX 
SET @SEL_SQL = CONCAT('CREATE NONCLUSTERED COLUMNSTORE INDEX XCSI_', @TBL_NM, ' ON dbo.', @TBL_NM, ' (',@COL_VAL, ') WITH (DROP_EXISTING = OFF) ON [PRIMARY]') 
--SELECT @SEL_SQL 
EXEC (@SEL_SQL) 

END
