SQL Server : TSQL中拆分字符串的一个自定义函数

今天写到的一个函数
create function [dbo].[split]
(
@SourceSql varchar(8000),
@StrSeprate varchar(10)
)
returns @temp table(F1 varchar(100))
as
begin
    declare @i int
    set @SourceSql = rtrim(ltrim(@SourceSql))
    set @i = charindex(@StrSeprate,@SourceSql)
    while @i >= 1
    begin
        if len(left(@SourceSql,@i-1))>0
        begin
            insert @temp values(left(@SourceSql,@i-1))
        end
        set @SourceSql=substring(@SourceSql,@i+1,len(@SourceSql)-@i)
        set @i=charindex(@StrSeprate,@SourceSql)
    end
    if @SourceSql <> ''
        insert @temp values(@SourceSql)
    return
end

使用实例

ALTER PROC [dbo].[GetTaskData](
@userorgroup NVARCHAR(50))
AS
SELECT 
WorkflowNameUrl,
FormId,
WorkflowType,
CreateBy,
CreateTime,
LasttimeInquisitor,
LasttimeProcessTime,
State,
NextInquisitor From Table_Task 
WHERE EXISTS(SELECT F1 FROM split(NextInquisitorEn,';') WHERE F1=@userorgroup)
