由于您无法使用表参数（不适用于 SQL Server 2008），因此请尝试传入 CSV 字符串并让存储过程将其拆分为行。
SQL Server 中有多种分割字符串的方法。本文涵盖了几乎每种方法的优点和缺点：
“当表值参数无法满足 SQL Server 2005 及更高版本中的数组和列表时”作者：Erland Sommarskog
您需要创建一个拆分函数。这是 split 函数的使用方式：
SELECT
*
FROM YourTable y
INNER JOIN dbo.yourSplitFunction(@Parameter) s ON y.ID=s.Value
我更喜欢在 SQL 中使用数字表方法来分割字符串但是 SQL Server 中有多种分割字符串的方法，请参阅前面的链接，其中解释了每种方法的优点和缺点。
为了使数字表方法发挥作用，您需要执行一次时间表设置，这将创建一个表Numbers包含从 1 到 10,000 的行：
SELECT TOP 10000 IDENTITY(int,1,1) AS Number
INTO Numbers
FROM sys.objects s1
CROSS JOIN sys.objects s2
ALTER TABLE Numbers ADD CONSTRAINT PK_Numbers PRIMARY KEY CLUSTERED (Number)
设置 Numbers 表后，创建此拆分函数：
CREATE FUNCTION [dbo].[FN_ListToTable]
(
@SplitOn char(1) --REQUIRED, the character to split the @List string on
,@List varchar(8000)--REQUIRED, the list to split apart
)
RETURNS TABLE
AS
RETURN
( ----------------
--SINGLE QUERY-- --this will not return empty rows
----------------
SELECT
ListValue
FROM (SELECT
LTRIM(RTRIM(SUBSTRING(List2, number+1, CHARINDEX(@SplitOn, List2, number+1)-number - 1))) AS ListValue
FROM (
SELECT @SplitOn + @List + @SplitOn AS List2
) AS dt
INNER JOIN Numbers n ON n.Number < LEN(dt.List2)
WHERE SUBSTRING(List2, number, 1) = @SplitOn
) dt2
WHERE ListValue IS NOT NULL AND ListValue!=''
);
GO
您现在可以轻松地将空格分隔的字符串拆分到表中并加入它或根据需要使用它此代码基于 OP 的最新问题编辑：
CREATE TABLE YourTable (PK int, col1 varchar(20), col2 varchar(20), col3 varchar(20))
--data from question
INSERT INTO YourTable VALUES (1,'hello xyz','abc is my last name','and i''m a developer')
INSERT INTO YourTable VALUES (2,'hello xyz',null,'and i''m a developer')
CREATE PROCEDURE YourProcedure
(
@keywords varchar(1000)
)
AS
SELECT
@keywords AS KeyWords,y.*
FROM (SELECT
t.PK
FROM dbo.FN_ListToTable(' ',@keywords) dt
INNER JOIN YourTable t ON t.col1 LIKE '%'+dt.ListValue+'%' OR t.col2 LIKE '%'+dt.ListValue+'%' OR t.col3 LIKE '%'+dt.ListValue+'%'
GROUP BY t.PK
HAVING COUNT(t.PK)=(SELECT COUNT(*) AS CountOf FROM dbo.FN_ListToTable(' ',@keywords))
) dt
INNER JOIN YourTable y ON dt.PK=y.PK
GO
--from question
EXEC YourProcedure 'xyz developer'-- returns 2 rows
EXEC YourProcedure 'xyz abc'-- returns 1 row
EXEC YourProcedure 'abc developer'-- returns 1 row
EXEC YourProcedure 'hello'-- returns 2 rows
EXEC YourProcedure 'hello developer'-- returns 2 rows
EXEC YourProcedure 'xyz'-- returns 2 rows
OUTPUT:
KeyWords PK col1 col2 col3
-------------- ----- ---------- -------------------- --------------------
