我有以下存储过程,该存储过程接受使用两个定界符的字符串。该过程提取数据并将其插入DB。这就像如果我有一个键值对 (示例输入字符串) 说“ 10:1,11:2,12:3”,我也需要在 “ Id” 列中寻找值“ 10”并在其中插入值1在 “值” 列等。该过程的代码如下:
ALTER PROCEDURE [SQL_Delimiter_TestProcedure] @inputStr VARCHAR(MAX) AS BEGIN DECLARE @t table (val varchar(500)) INSERT INTO @t (val)values (@inputStr) ;WITH CTE AS ( SELECT Split.a.value('.', 'VARCHAR(500)') AS String FROM (SELECT CAST ('<M>' + REPLACE([val], ',', '</M><M>') + '</M>' AS XML) AS String FROM @t) AS A CROSS APPLY String.nodes ('/M') AS Split(a)) INSERT INTO SQL_Delimiter_Test select SUBSTRING(String,0,CHARINDEX(':',String)),REVERSE(SUBSTRING(reverse(String),0,CHARINDEX(':',reverse(String)))) from cte END
这是简短的版本:
首先,创建一个用户定义的表类型:
CREATE TYPE KeyValuePair As Table ( Key int PRIMARY KEY, Value int )
然后将其用作存储过程中的表值参数:
ALTER PROCEDURE [SQL_Delimiter_TestProcedure] ( @KeyValuePair as KeyValuePair readonly ) AS BEGIN INSERT INTO SQL_Delimiter_Test (Id, Value) SELECT Key, Value FROM @KeyValuePair END
