Question

我有一个存储过程，我想每天运行。我在存储过程中有一个约束，如果当前日期等于表中的最大日期，它就不能将数据插入表中，如下所示：

-- MAKE SURE IT WAS NOT RUN FOR THE DAY ALREADY
AND CAST(GETDATE() AS date) != (SELECT MAX(RUNDATE) FROM smsdss.c_ins_bal_amt)

在测试期间，我截断了表格。当我执行sp exec smsdss.c_ins_bal_amt_sp;然后检查结果表中的数据时，它是空白的。所以我运行了INSERT查询，如果已经创建了表，并确定没有结果，我发现它肯定是因为前面提到的行。

我该如何纠正？如果由于某种原因我将来截断表格（这真的不应该发生......但是）

如果需要，以下是sp的全部内容：

/*
Check to see if the table even exists. If not create and populate, else insert
new records only if the run date is not already in the table.
*/
IF NOT EXISTS (
    SELECT TOP 1 * FROM sysobjects WHERE name='c_ins_bal_amt' AND xtype='U'
)

Answer 1

如果我理解你的权利而不是截断后检查(SELECT MAX(RUNDATE) FROM smsdss.c_ins_bal_amt)将返回null

这意味着你实际上是这样做的：

AND CAST(GETDATE() AS date) != NULL

你无法使用！=
来比较NULL 所以像这样调整你的支票

AND CONVERT(date, GETDATE()) <> convert(date, isnull((SELECT MAX(RUNDATE) FROM smsdss.c_ins_bal_amt), getdate() - 1))

通过这种方式，您可以随时查看有效日期，即使您的桌子已经剔除

Answer 2

AND CAST(GETDATE() AS date) != (SELECT isnull(MAX(RUNDATE), '19000101') FROM smsdss.c_ins_bal_amt)

Answer 3

如果我理解你的问题，你只需检查该表中是否有任何记录：

ISNULL({@DateRejected})
OR
{@DateRejected} < Minimum({?Date Received}) 
OR
{@DateRejected} > Maximum({?Date Received})

AND ( CAST(GETDATE() AS date) != (SELECT MAX(RUNDATE) FROM smsdss.c_ins_bal_amt) OR NOT EXISTS (SELECT * FROM smsdss.c_ins_bal_amt) )已定义为RUNDATE，因此只需查看表中记录的存在就足够了。

Answer 4

尝试使用虚拟日期在日期检查周围放置一个ISNULL：

    AND CAST(GETDATE() AS date) != isnull((SELECT MAX(RUNDATE)
    FROM smsdss.c_ins_bal_amt) , '7/4/1776')

Answer 5

如果你以后以某种方式截断表，你不会说你想要存储过程做什么。如果你只想让SP停止，那么只需在开头的

中添加一个检查

 If Not Exists (Select * from smsdss.c_ins_bal_amt) return 0

另一方面，如果您希望它忽略日期约束，请将相同的条件放入日期约束逻辑中：

WHERE VST.tot_bal_amt > 0
   AND VST.vst_end_date IS NOT NULL
   AND VST.fc not in ('1','2','3','4','5','6','7','8','9')
  -- MAKE SURE IT WAS NOT RUN FOR THE DAY ALREADY
   AND (Not exists(Select * from smsdss.c_ins_bal_amt)Or
         CAST(GETDATE() AS date) != 
           (SELECT MAX(RUNDATE) 
            FROM smsdss.c_ins_bal_amt))

或者，或者：

WHERE VST.tot_bal_amt > 0
   AND VST.vst_end_date IS NOT NULL
   AND VST.fc not in ('1','2','3','4','5','6','7','8','9')
  -- MAKE SURE IT WAS NOT RUN FOR THE DAY ALREADY
   AND CAST(GETDATE() AS date) != 
           CAST(coalesce(
              (SELECT MAX(RUNDATE FROM smsdss.c_ins_bal_amt), 
               getdate()) as date)

SQL 2014存储过程插入到表检查为空的表中
