当我通过应用程序执行存储过程时,SQL Server会引发超时,但在Management Studio中执行存储过程时不会引发超时
我有这样一个存储过程:当我通过应用程序执行存储过程时,SQL Server会引发超时,但在Management Studio中执行存储过程时不会引发超时,sql,sql-server,node.js,Sql,Sql Server,Node.js,我有这样一个存储过程: PROCEDURE [dbo].[myStoredProcedure] @period varchar(7), @pgSize int, @pg int, @sort varchar(50) AS BEGIN DECLARE @exec nvarchar(1000) DECLARE @order varchar(100) DECLARE @where varchar(100) CREATE TABLE #temp (
PROCEDURE [dbo].[myStoredProcedure]
@period varchar(7),
@pgSize int,
@pg int,
@sort varchar(50)
AS
BEGIN
DECLARE @exec nvarchar(1000)
DECLARE @order varchar(100)
DECLARE @where varchar(100)
CREATE TABLE #temp (
fieldOne varchar(7),
fieldTwo varchar(7),
fieldThree int,
fieldFour varchar(7)
)
If exists(select 1 from tableA Where date = @period)
Begin
INSERT INTO #temp
SELECT DISTINCT a.fieldOne, b.fieldTwo, td.fieldThree, b.fieldFour
FROM tableA a
LEFT JOIN docType td ON td.code = a.docType
INNER JOIN tableB b ON a.code = b.code
AND b.state= 'A'
AND a.date = convert(int, @period);
END
ELSE
BEGIN
INSERT INTO #temp
SELECT DISTINCT a.fieldOne, b.fieldTwo, td.fieldThree, b.fieldFour
FROM tableAHistoric a
LEFT JOIN docType td ON td.code = a.docType
INNER JOIN tableBHistoric b ON a.code = b.code
AND b.state= 'A'
AND a.date = convert(int, @period);
END
-- Eliminate registers such that there is another register with the same fieldOne but different fieldTwo, and keep the one that has smaller fieldThree or,
-- in case they are equal, keep the one with smallest fieldFour
DELETE t1
FROM #temp t1
INNER JOIN #temp t2 ON t1.fieldOne = t2.fieldOne AND t1.fieldTwo <> t2.fieldTwo
WHERE t1.fieldThree > t2.fieldThree OR (t1.fieldThree = t2.fieldThree AND t1.fieldFour > t2.fieldFour)
SET @order = ' order by ' + CASE LEFT(@sort, 1) WHEN '-' THEN SUBSTRING(@sort, 2, LEN(@sort) - 1) + ' desc' ELSE @sort END
IF @pg = 1
BEGIN
SET @exec = CONCAT(
'select * from #temp ',
@order,
' offset (@pg-1) * @pgSize rows fetch next @pgSize rows only '
)
EXEC sp_executesql @exec, N'@pg int, @pgSize int', @pg = @pg, @pgSize = @pgSize
SELECT rows = COUNT(*) FROM #temp
END
ELSE
BEGIN
SET @exec = CONCAT(
'select * from #temp ',
@order,
' offset (@pg-1) * @pgSize rows fetch next @pgSize rows only '
)
EXECUTE sp_executesql @exec, N'@pg int, @pgSize int', @pg = @pg, @pgSize = @pgSize
END
它在一秒钟内返回
如果我在变量@period中硬编码“201603”,并从Node.js应用程序执行存储过程,它也会在一秒钟内返回
但是,如果在通过Node.js应用程序执行存储过程时传递该参数,则会得到一个超时。我已经注册,存储过程要么永远无法执行INSERT,要么永远无法在超时之前完成。超时设置为15秒,我将其设置为2分钟进行测试,但结果是一样的:超时。有趣的是,它只发生在值“201603”的情况下。结果应返回889个寄存器。我已经用其他返回200个结果的值进行了测试,它们没有问题
作为参考,字段日期为整数。但即使我在WHERE子句中转换参数@period,也不会有任何变化
有什么问题吗?我应该调查什么
谢谢。可能是缓存的执行计划
尝试在SP的底部添加选项“重新编译”进程中没有@period用作VARCHAR,那么为什么要将其声明为VARCHAR呢?如果你只把它作为一个INT,你应该把它声明为INT。@Siyual:虽然这是一个很好的观点,但我发现把@period作为INT传递给这个问题没有任何区别。
EXEC myStoredProcedure '201603', 10, 1, 'fieldOne'
