Question

当我插入Emp时，任何人都可以修改它。命名它去第一次搜索，它不会检查其他参数你可以根据参数修改此sp进行精确搜索。

--select * from Training_TRNS
--USP_SearchEmployee '','2008-04-18 00:00:00.000','','','','',''
alter Procedure USP_SearchEmployee 
@EmpName varchar(100)=null,
@DateFrom varchar(100)=null,
@DateTo varchar(100)=null,
@CourseName varchar(100)=null,
@JobFunction varchar(100)=null,
@Region varchar(100)=null,
@Status varchar(100)=null
AS

BEGIN
if (@EmpName!='' and @EmpName is not null)
    BEGIN
        select EmpName,convert(varchar,DueDate,101) as  DueDate,SpeCourse_ID as CourseName,
        EmpJobFunction as JOBFunction,EmpRegion as Region,Status
        from Training_TRNS where EmpName like '%'+@EmpName+'%'
    END
ELSE IF  (@CourseName!='' and @CourseName is not null)
    BEGIN
        select EmpName,convert(varchar,DueDate,101) as  DueDate,SpeCourse_ID as CourseName,
        EmpJobFunction as JOBFunction,EmpRegion as Region,Status
        from Training_TRNS where SpeCourse_ID like '%'+@CourseName+'%'
    END

ELSE IF  (@JobFunction!='' and @JobFunction is not null)
    BEGIN
        select EmpName,convert(varchar,DueDate,101) as  DueDate,SpeCourse_ID as CourseName,
        EmpJobFunction as JOBFunction,EmpRegion as Region,Status
        from Training_TRNS where EmpJobFunction like '%'+@JobFunction+'%'
    END

ELSE IF  (@Region!='' and @Region is not null)
    BEGIN
        select EmpName,convert(varchar,DueDate,101) as  DueDate,SpeCourse_ID as CourseName,
        EmpJobFunction as JOBFunction,EmpRegion as Region,Status
        from Training_TRNS where EmpRegion like '%'+@Region+'%'
    END

ELSE IF  (@Status!='' and @Status is not null)
    BEGIN
        select EmpName,convert(varchar,DueDate,101) as  DueDate,SpeCourse_ID as CourseName,
        EmpJobFunction as JOBFunction,EmpRegion as Region,Status
        from Training_TRNS where Status like '%'+@Status+'%'
    END

ELSE IF  (@DateFrom!='' and @DateFrom is not null)
    BEGIN
        select EmpName,convert(varchar,DueDate,101) as  DueDate,SpeCourse_ID as CourseName,
        EmpJobFunction as JOBFunction,EmpRegion as Region,Status
        from Training_TRNS where convert(varchar,DueDate,101) like '%'+convert(varchar,@DateFrom,101)+'%'
    END


Else
    BEGIN
        select EmpName,convert(varchar,DueDate,101) as  DueDate,SpeCourse_ID as CourseName,
        EmpJobFunction as JOBFunction,EmpRegion as Region,Status
        from Training_TRNS
    END

END

Answer 1

试试这个。

alter Procedure USP_SearchEmployee 
@EmpName varchar(100)=null,
@DateFrom varchar(100)=null,
@DateTo varchar(100)=null,
@CourseName varchar(100)=null,
@JobFunction varchar(100)=null,
@Region varchar(100)=null,
@Status varchar(100)=null
AS

BEGIN
        select EmpName,convert(varchar,DueDate,101) as  DueDate,SpeCourse_ID as CourseName,
        EmpJobFunction as JOBFunction,EmpRegion as Region,Status
        from Training_TRNS 
        where 
                EmpName = isnull(ltrim(rtrim(@EmpName)), EmpName) or EmpName like '%'+@EmpName+'%'
        and     SpeCourse_ID = isnull(ltrim(rtrim(@CourseName)), SpeCourse_ID) or SpeCourse_ID like '%'+@CourseName+'%'
        and     EmpJobFunction = isnull(ltrim(rtrim(@JobFunction)), EmpJobFunction) or EmpJobFunction like '%'+@JobFunction+'%'
        and     EmpRegion = isnull(ltrim(rtrim(@Region)), EmpRegion) or EmpRegion like '%'+@Region+'%'
        and     status = isnull(ltrim(rtrim(@status)), status) or status like '%'+@status+'%'
        and     DueDate = isnull(@DateFrom, DueDate) or convert(varchar,DueDate,101) like '%'+convert(varchar,@DateFrom,101)+'%'

END

尝试这样的事情：

DECLARE @sql nvarchar(MAX) -- this would work only is this is SQL2005/2008, else nvarchar(4000) 

SET @sql='select EmpName,convert(varchar,DueDate,101) as  DueDate,SpeCourse_ID as CourseName,
        EmpJobFunction as JOBFunction,EmpRegion as Region,Status
        from Training_TRNS where 1=1 '

IF (@EmpName!='' and @EmpName is not null)
    SET @sql=@sql + ' AND EmpName like ''%'+ @EmpName+ '%'''

IF  (@CourseName!='' and @CourseName is not null)
    SET @sql=@sql + ' AND CourseName like ''%'+ @CourseName+ '%'''

IF (@JobFunction!='' and @JobFunction is not null)
        SET @sql=@sql + ' AND EmpJobFunction like ''%'+ @JobFunction + '%'''

IF  (@Region!='' and @Region is not null)
     SET @sql=@sql + ' AND EmpRegion like ''%'+ @Region+ '%'''

IF  (@Status!='' and @Status is not null)
     SET @sql=@sql + ' AND Status like ''%'+ @Status+ '%'''

IF (@DateFrom!='' and @DateFrom is not null)
     SET @sql=@sql + ' AND convert(varchar,DueDate,101) like ''%'+convert(varchar,@DateFrom,101)+ '%'''

EXEC sp_executesql @sql

基于多个参数的搜索字段
