IF OBJECT_ID('tempdb..#iftry') IS NOT NULL
DROP TABLE #iftry
IF OBJECT_ID('BIC_Analytics.dbo.AdjudicateAllDCCharteredClaims') IS NULL
begin
select 'this is start of first block'
SELECT 'this is first block' as blockid
INTO #iftry
select 'this is end of first block'
end
ELSE
begin
select 'this is start of 2nd block'
SELECT 'this is 2nd block' as blockid
INTO #iftry
select 'this is end of 2nd block'
end
select ':)'
select * from #iftry
一直给我错误:
Msg 2714, Level 16, State 1, Line 18
There is already an object named '#iftry' in the database.
现在可以了
IF OBJECT_ID('tempdb..#iftry') IS NOT NULL
DROP TABLE #iftry
create table #iftry (blockid varchar(20))
IF OBJECT_ID('BIC_Analytics.dbo.AdjudicateAllDCCharteredClaims') IS NOT NULL
begin
--select 'this is start of first block'
insert into #iftry (blockid)
select 'this is first block'
--select 'this is end of first block'
end
ELSE
begin
--select 'this is start of 2nd block'
insert into #iftry (blockid)
select 'this is 2nd block'
--select 'this is end of 2nd block'
end
select ':)'
select * from #iftry
最佳答案
这是解析问题,不是运行时问题。 SQL Server 看不到有两个代码路径无法访问。
要解决它,请先创建一次#temp 表:
SELECT 'bogus' INTO #iftry
WHERE 1 = 0; -- creates empty table
IF ...
INSERT #iftry ...
ELSE ...
INSERT #iftry ...
没有办法告诉 SQL Server 不要以这种方式工作,除非你将两个 #table 声明放在不同的批处理中(你不能真正这样做),或者构建动态 SQL 并在该范围内使用 #temp 表(不好玩)。
