Question

我有这个存储过程，我将@CourseID作为

传递给我

|CRS0001095|CRS0001223|CRS0001224|CRS0001225|CRS0001229|CRS0001238|CRS000124

来自Web应用程序。但我想将此字符串替换为

'CRS0001095', 'CRS0001223', 'CRS0001224', 'CRS0001225', 'CRS0001229', 'CRS0001238', 'CRS000124'

这样我就可以将此字符串传递给我的查询。

我尝试了Replace，但这会导致错误。我该如何更改该字符串？

ALTER PROCEDURE [dbo].[LSS_e_test_sp]
    @TRANTYPE VARCHAR(30)='',
    @PARAM1 VARCHAR(30)='',
    @PARAM2 VARCHAR(30)='',
    @PARAM3 VARCHAR(30)='',
    @PARAM4 VARCHAR(30)='',
    @PARAM5 VARCHAR(3000)=''
AS
    DECLARE 
        @WORKORDERNO VARCHAR(20),
        @EVENTPOINT VARCHAR(30),
        @LASTEDITBY VARCHAR(30),
        @ERRMSG VARCHAR(500),
        @ProductionLine VARCHAR(100),
        @CourseID VARCHAR(3000),
        @OperatorsTraLevel VARCHAR(30),
        @reqOperatorLevel VARCHAR(30)

    IF @TRANTYPE = 'getOperatorLavel'
    BEGIN
        SET @WORKORDERNO = @PARAM1
        SET @EVENTPOINT = @PARAM2
        SET @LASTEDITBY = @PARAM3
        SET @CourseID = @PARAM5

        Print @WORKORDERNO
        Print @EVENTPOINT
        Print @LASTEDITBY
        Print @CourseID

        select @OperatorsTraLevel = MAX(convert(real, TraingLavel)) 
        from ftx_tm_courselevelMapping 
        where coursenumber in (@CourseID)

        print @OperatorsTraLevel

        RETURN 0
END

Answer 1

尝试另一条路线：

imports

甚至不要拆分WHERE CHARINDEX(coursenumber,@CourseID)>0并选择@CourseID字符串中coursenumber所在的数据。

Answer 2

我假设你在IN Clause中使用@CourseID，所以你可以做类似的事情


declare @str nvarchar(max) = '|CRS0001095|CRS0001223|CRS0001224|CRS0001225|CRS0001229|CRS0001238|CRS000124';
declare @ret_list as table ( cr_id nvarchar(max) );
declare @pos int;
declare @cr_id nvarchar(max)

while CHARINDEX('|', @str) > 0
begin
    select @pos = CHARINDEX('|', @str);
    select @cr_id = substring(@str, 1, @pos-1);
    insert into @ret_list (cr_id) values (@cr_id);
    select @str = SUBSTRING(@str, @pos+1, LEN(@str) - @pos)

end
select * from @ret_list where cr_id not like ''

之后，请替换以下内容：

 select @OperatorsTraLevel = MAX(convert (real, TraingLavel)) from ftx_tm_courselevelMapping where coursenumber in (@CourseID)

带

 select @OperatorsTraLevel = MAX(convert (real, TraingLavel)) from ftx_tm_courselevelMapping where coursenumber in (select cr_id from @ret_list where cr_id not like '')

你应该是金色的！

Answer 3

如果您的MS SQL Server是2016，那么您可以享受string_split功能。

...where si in (select value from string_split(@CourseID,'|'))

否则，如果MS SQL Server是2008或更新版本，则可以在查询中拆分字符串。

;with dat(x) as (
select cast( '<s>'+replace(@CourseID,'|','</s><s>')+'</s>' as xml)
)
select @OperatorsTraLevel = MAX(convert (real, TraingLavel)) 
from ftx_tm_courselevelMapping cross join dat
where coursenumber in (select t.v.value('.[1]','varchar(20)') from x.nodes('s') t(v))
