Question

我想在sproc中使用插入查询中的IF-Else。我尝试过这段代码，并收到错误。怎么了？

    create procedure sp_m_ii_2_kaydet
@mtu int,
@mod int,
@moid int,
@uid int
as
insert into m_ii2_alisfatura 
(muhtur, mturid, muhodm, modmid, uid) values 
(@mtu, 
IF (@mtu = 3) SELECT MAX(id) FROM m_ii1_vsf_personel
ELSE IF (@mtu = 2) SELECT MAX(id) FROM m_ii1_vsf_firma
ELSE IF (@mtu = 4) SELECT MAX(id) FROM m_ii1_vsf_taseron, 
@mod, @moid, @uid)

Answer 1

这不是一个有效的语法试试这个

您需要使用三种不同的插入语句

      var dataTest = data.replace(/[^-0-9]/gi, '');

或通过过滤where子句

中的数据来使用

CREATE PROCEDURE Sp_m_ii_2_kaydet @mtu  INT,
                                  @mod  INT,
                                  @moid INT,
                                  @uid  INT
AS
    IF ( @mtu = 3 )
      INSERT INTO m_ii2_alisfatura
                  (muhtur,mturid,muhodm,modmid,uid)
      SELECT @mtu,Max(id),@mod,@moid,@uid
      FROM   m_ii1_vsf_personel
    ELSE IF ( @mtu = 2 )
      INSERT INTO m_ii2_alisfatura
                  (muhtur,mturid,muhodm,modmid,uid)
      SELECT @mtu,Max(id),@mod,@moid,@uid
      FROM   m_ii1_vsf_firma
    ELSE IF ( @mtu = 4 )
      INSERT INTO m_ii2_alisfatura
                  (muhtur,mturid,muhodm,modmid,uid)
      SELECT @mtu,Max(id),@mod,@moid,@uid
      FROM   m_ii1_vsf_taseron

union all

甚至CREATE PROCEDURE Sp_m_ii_2_kaydet @mtu INT, @mod INT, @moid INT, @uid INT AS INSERT INTO m_ii2_alisfatura (muhtur,mturid,muhodm,modmid,uid) SELECT @mtu,Max(id),@mod,@moid,@uid FROM m_ii1_vsf_personel WHERE @mtu = 3 UNION ALL SELECT @mtu,Max(id),@mod,@moid,@uid FROM m_ii1_vsf_firma WHERE @mtu = 2 UNION ALL SELECT @mtu,Max(id),@mod,@moid,@uid FROM m_ii1_vsf_taseron WHERE @mtu = 4声明

case

注意：如果至少有一个条件不匹配，前两个查询将不会插入任何记录。但case语句将插入数据将为null值，即使没有条件匹配

Answer 2

如果您使用的是SQL Server 2012或更高版本，

infact 您可以使用类似的语法。

<强>例如

create table #tt(Id int)

create table #tu(tid int)
insert into #tu values(1),(2)

declare @test int = 1
insert into #tt
values (iif(@test=1,(select min(tid) from #tu),(select max(tid) from #tu)))

select * from #tt

您的查询已修改

  create procedure sp_m_ii_2_kaydet
@mtu int,
@mod int,
@moid int,
@uid int
as
insert into m_ii2_alisfatura 
(muhtur, mturid, muhodm, modmid, uid) values 
(@mtu, 
IIF (@mtu = 3, (SELECT MAX(id) FROM m_ii1_vsf_personel),IIF(@mtu = 2,(SELECT MAX(id) FROM m_ii1_vsf_firma),
IIF(@mtu = 4,( SELECT MAX(id) FROM m_ii1_vsf_taseron),0))),
@mod, @moid, @uid)

Answer 3

我使用这个组合代码得到了错误的MAX（ID）值;

    ...procedure [dbo].[sp_m_ii_2_kaydet]
@mtu int,
@mod int,
@uid int
as
declare @mtuid int
declare @modid int
if (@mtu = 3 and @mod = 1) 
set @mtuid = (select MAX(id) from m_ii1_vsf_personel)
    set @modid = (select MAX(id) from m_kasa_personel);
if (@mtu = 3 and @mod = 2)
set @mtuid = (select MAX(id) from m_ii1_vsf_personel)
    set @modid = (select MAX(id) from m_hesap_personel);
if (@mtu = 3 and @mod = 3)
set @mtuid = (select MAX(id) from m_ii1_vsf_personel)
    set @modid = (select MAX(id) from m_senet_personel);
if (@mtu = 3 and @mod = 4)
set @mtuid = (select MAX(id) from m_ii1_vsf_personel)
    set @modid = (select MAX(id) from m_cekcikis_personel);
if (@mtu = 2 and @mod = 1) 
set @mtuid = (select MAX(id) from m_ii1_vsf_firma)
    set @modid = (select MAX(id) from m_kasa_firma);
if (@mtu = 2 and @mod = 2)
set @mtuid = (select MAX(id) from m_ii1_vsf_firma)
    set @modid = (select MAX(id) from m_hesap_firma);
if (@mtu = 2 and @mod = 3)
set @mtuid = (select MAX(id) from m_ii1_vsf_firma)
    set @modid = (select MAX(id) from m_senet_firma);
if (@mtu = 2 and @mod = 4)
set @mtuid = (select MAX(id) from m_ii1_vsf_firma)
    set @modid = (select MAX(id) from m_cekcikis_firma);
if (@mtu = 4 and @mod = 1) 
set @mtuid = (select MAX(id) from m_ii1_vsf_taseron)
    set @modid = (select MAX(id) from m_kasa_taseron);
if (@mtu = 4 and @mod = 2)
set @mtuid = (select MAX(id) from m_ii1_vsf_taseron)
    set @modid = (select MAX(id) from m_hesap_taseron);
if (@mtu = 4 and @mod = 3)
set @mtuid = (select MAX(id) from m_ii1_vsf_taseron)
    set @modid = (select MAX(id) from m_senet_taseron);
if (@mtu = 4 and @mod = 4)
set @mtuid = (select MAX(id) from m_ii1_vsf_taseron) 
    set @modid = (select MAX(id) from m_cekcikis_taseron);
insert into m_ii2_alisfatura (muhtur, mturid, muhodm, modmid, uid) values
(@mtu, @mtuid, @mod, @modid, @uid)

在SQL Server插入查询中使用IF-ELSE
