【中文标题】将存储过程数据插入临时表不起作用【英文标题】：Insert stored procedure data into temp table not working 【发布时间】：2016-03-15 11:35:46 【问题描述】：我创建了一个带有 3 个参数的存储过程。见下文
ALTER PROCEDURE [dbo].[Leave_Allocation_Mar_2016]
@Type nvarchar(10),
@Month int,
@Year int
AS
BEGIN
declare @emp_card_no numeric(9)
declare @emp_name varchar(20)
declare @dt_of_join datetime
declare @Total_days numeric(5,2)
declare @Days_worked numeric(5,2)
declare @Final_PaidDayLop numeric(5,2)
declare @TotalRecord int
declare @actualMonth int
declare @actualYear int
declare @actuallastdate varchar(20)
IF(@Type = 'C')
BEGIN
Print 'Yes I am in the Current process';
DECLARE daily_Allocate CURSOR FOR
Select distinct c.emp_card_no, c.emp_name, c.Dt_Of_Join from emp_mst c
join emp_mon_day d
on c.emp_card_no=d.emp_mkey
WHERE Dt_Of_Join = CAST(FLOOR(CAST( DATEADD(month, -6, GETDATE()) AS FLOAT ))AS DATETIME)
OPEN daily_Allocate
FETCH NEXT FROM daily_Allocate INTO
@emp_card_no, @emp_name, @Dt_Of_Join
WHILE @@FETCH_STATUS = 0
BEGIN
select @Total_days = Sum(total_day),@Days_worked = Sum(days_worked)
from emp_mon_day a
where a.emp_mkey = 2519
group by emp_mkey
PRINT 'Employee Card no = ' + cast(@emp_card_no as char)
PRINT 'Total days = ' + cast(@Total_days as char)
PRINT 'Days Worked = ' + cast(@Days_worked as char)
set @Final_PaidDayLop = 0;
set @TotalRecord = 0;
Select @Final_PaidDayLop =
isnull(sum(days),0)
from P_Emp_Del_App_Hdr c join P_Emp_Del_App_trl d on c.mkey=d.mkey
where c.delete_flag='N' and app_flag='Y' and c.year = @actualYear
and c.emp_mkey = @emp_card_no
Select @TotalRecord = ((1.75 * 6) / @Total_days) * (@Days_worked + @Final_PaidDayLop)
from emp_mon_day a where a.emp_mkey = @emp_card_no group by a.emp_mkey
PRINT 'Final Paid LOP ' + cast(coalesce(@Final_PaidDayLop,0) as char)
PRINT 'Total Record ' + cast(coalesce(@TotalRecord,0) as char)
FETCH NEXT FROM daily_Allocate INTO
@emp_card_no, @emp_name, @Dt_Of_Join
END
CLOSE daily_Allocate
DEALLOCATE daily_Allocate
END END
这给了我如下输出
现在我想要的是，我想将上面的数据插入到临时表中。
我尝试如下
CREATE TABLE #tmp1111
(
Sr_no int identity(1,1),
Current_Status nvarchar(255),
Emp_card_no int,
Total_days int,
days_worked int,
final_lop_paid int,
total_record int
)
首先我创建了一个临时表并尝试插入如下数据
INSERT INTO #tmp1111 exec Leave_Allocation_Mar_2016 'C', '2', '2016'
它执行成功，但是当我运行 select 语句时，临时表中没有记录。
我正在使用 SQL server 2005
【问题讨论】：
存储过程没有直接输出，只有变量的打印。您需要返回正在打印的这些项目，可能作为 SELECT @VarName。但是不清楚您在寻找什么，因为光标内可能有多个这些？ @Paddy：我只想将记录插入到临时表中，这是通过在存储过程中打印得到的。如果除了打印之外我将值插入到表中然后让我知道..希望你现在清楚 为什么要从外部执行存储过程？如果只需要这些参数，则传递到存储过程 【参考方案1】：代替@Result 表变量使用如下：
CREATE TABLE #Results
(
Emp_card_no NUMERIC(9),
Total_days NUMERIC(5,2),
Days_worked NUMERIC(5,2),
Final_PaidDayLop NUMERIC(5,2),
TotalRecord INT
)
INSERT INTO #Results
(
Emp_card_no,
Total_days,
Days_worked,
Final_PaidDayLop
)
VALUES
(
@emp_card_no , -- Emp_card_no - numeric
@Total_days , -- Total_days - numeric
@Days_worked , -- Days_worked - numeric
@Final_PaidDayLop -- Final_PaidDayLop - numeric
)
在 DEALLOCATE daily_Allocate 之后插入语句
SELECT * FROM #Results
DROP TABLE #Results
此select语句返回执行游标时在#Results临时表中插入记录的所有行
进行这些更改，希望这对您有所帮助
更新：
ALTER PROCEDURE [dbo].[Leave_Allocation_Mar_2016]
@Type NVARCHAR(10),
@Month INT,
@Year INT
AS
BEGIN
SET NOCOUNT ON;
CREATE TABLE #Results

BEGIN

DECLARE daily_Allocate CURSOR
LOCAL SCROLL STATIC
FOR
SELECT DISTINCT c.emp_card_no, c.emp_name, c.Dt_Of_Join FROM emp_mst c
JOIN emp_mon_day d ON c.emp_card_no=d.emp_mkey

OPEN daily_Allocate
FETCH NEXT FROM daily_Allocate INTO @emp_card_no, @emp_name, @Dt_Of_Join
WHILE @@FETCH_STATUS = 0
BEGIN
SELECT @Total_days = SUM(total_day), @Days_worked = SUM(days_worked)
FROM emp_mon_day a
WHERE a.emp_mkey = 2519
GROUP BY emp_mkey
PRINT 'Employee Card no = ' + cast(@emp_card_no AS CHAR)
PRINT 'Total days = ' + cast(@Total_days AS CHAR)
PRINT 'Days Worked = ' + cast(@Days_worked AS CHAR)
SET @Final_PaidDayLop = 0;
SET @TotalRecord = 0;
SELECT @Final_PaidDayLop = ISNULL(SUM(days), 0)
FROM P_Emp_Del_App_Hdr c JOIN P_Emp_Del_App_trl d ON c.mkey=d.mkey
WHERE c.delete_flag='N' AND app_flag='Y' AND c.year = @actualYear
AND c.emp_mkey = @emp_card_no
SELECT
@TotalRecord = ((1.75 * 6) / @Total_days) * (@Days_worked + @Final_PaidDayLop)

GROUP BY a.emp_mkey
PRINT 'Final Paid LOP ' + CAST(COALESCE(@Final_PaidDayLop, 0) AS CHAR)
PRINT 'Total Record ' + CAST(COALESCE(@TotalRecord, 0) AS CHAR)
INSERT INTO #Results
(
Emp_card_no,
Total_days,
Days_worked,
Final_PaidDayLop
)
VALUES
(
@emp_card_no , -- Emp_card_no - numeric
@Total_days , -- Total_days - numeric
@Days_worked , -- Days_worked - numeric
@Final_PaidDayLop -- Final_PaidDayLop - numeric
)
FETCH NEXT FROM daily_Allocate INTO @emp_card_no, @emp_name, @Dt_Of_Join
END
CLOSE daily_Allocate
DEALLOCATE daily_Allocate
SELECT * FROM #Results
DROP TABLE #Results
END
END
然后EXEC Leave_Allocation_Mar_2016 'C', '2', '2016'你将在表格输出中得到结果
【讨论】：
是的，您可以根据需要添加更多参数 在执行存储过程时，您肯定会得到所有插入到#Result 表中的记录。 让我们continue this discussion in chat。【参考方案2】：存储过程没有直接输出，只有变量打印。您需要返回所需的值，例如在表格内：
请注意，该表是必需的，而不仅仅是返回变量，因为您的光标内可能有多个循环

我还建议整理变量命名的格式和一致性，以便更容易手动解析。一些错误处理以确保您的光标也始终关闭会很有用。
还建议将光标声明为 FAST_FORWARD、READ_ONLY：
What is the advantage of using FAST_FORWARD for defining a cursor?
【讨论】：
从表名中选择 *？ 我像这样跑Select * from Results，但给出错误Invalid object name 'Results'.
@coder 希望此链接有助于声明表变量值范围dba.stackexchange.com/questions/69217/…
@KrunalMevada：你能更新一下，让我知道我的情况吗，因为我也对那个链接感到困惑
没有表'Results' - 它被称为@Results，它位于sproc 的范围内，而不是在它之外。如果您只是执行存储过程，您应该会看到结果，或者像以前一样将它们插入 #Temp 并从中选择。【参考方案3】：
不是打印值，而是将其存储在局部变量中（或插入表变量中）并从存储过程中返回，然后它将起作用
例如：-
BEGIN
....
DECLARE @v_str AS NVARCHAR(500)
SET @v_str = ''
...
SELECT @v_str = @v_str+'Yes I am in the Current process'
...
SELECT @v_str = @v_str+'Total Records'
.
.
SELECT @v_str AS result
END
【讨论】：
【参考方案4】：试试这个而不是光标：
declare @dt_of_join date
set @dt_of_join = DATEADD(month, -6, GETDATE())
Select
c.emp_card_no, c.emp_name,
(1.75 * 6) / NullIf(d.Total_days, 0)) * (IsNull(d.Days_worked, 0) + IsNull(p.Final_PaidDayLop, 0)) as TotalRecord
from dbo.emp_mst c
outer apply
(
select
sum(d.total_day) as total_days
sum(d.days_worker) as days_worker
from dbo.emp_mon_day d
WHERE d.emp_mkey = c.emp_card_no
GROUP BY d.emp_mkey
) d
outer apply
(
select sum(cc.days) as Final_PaidDayLop
from P_Emp_Del_App_Hdr cc
inner join P_Emp_Del_App_trl dd on cc.mkey=d.mkey
where cc.delete_flag='N' and dd.app_flag='Y'
and cc.year = c.Dt_Of_Join
and cc.emp_mkey = c.emp_card_no
) p
where c.Dt_Of_Join = @dt_of_join
不确定是否猜对了所有内容（包括别名）。
如果您愿意，可以使用insert exec 或任何其他插入临时表的方式。
