检测昨天负载和今天负载之间差异但填充错误的查询

Question

我们正在转换旧的旧程序并将其集成到 SSIS 中。旧程序向需要通知帐户更改的最终用户输出一个显示帐户差异的文件。这是我试图执行此操作的查询，但我收到错误“varchar 值'02393224650'的转换溢出了一个 int 列。”在你说“可能重复”之前。其他帖子都没有正确回答这个问题，也没有涉及以这种方式实现逻辑的查询。

      SELECT
      a.run_id,
      a.AccountNumber,
      a.AccountBranch,
      a.AccountName,
      a.AccountType,
      a.CostCenter,
      b.TransactionLimit,
      b.ClientName,
      b.DailyCumulativeLimit
    FROM 
      AEI_GFXAccounts a
      LEFT JOIN AEI_GFXAccountSTP as b
      ON 
        a.feed_id = b.feed_id and 
        a.run_id = b.run_id and a.GFXAccountsID = b.GFXAccountSTPID), 
yest AS (
  SELECT * FROM data WHERE run_id = (SELECT MAX(run_id)-1 FROM AEI_GFXAccounts)
),
toda AS (
  SELECT * FROM data WHERE run_id = (SELECT MAX(run_id) FROM AEI_GFXAccounts)
)

SELECT

  toda LEFT JOIN yest ON toda.accountNumber = yest.AccountNumber

WHERE

      SELECT
      a.run_id,
      a.AccountNumber,
      a.AccountBranch,
      a.AccountName,

      ON 
        a.feed_id = b.feed_id and 
        a.run_id = b.run_id and a.GFXAccountsID = b.GFXAccountSTPID

我希望它返回一个仅显示所有已更改帐户的视图/查询结果。使用不依赖于填充 n/a 数据的字段。但我却得到了错误：

消息 248，第 16 级，状态 1，第 5 行

varchar 值 '02393224650' 的转换溢出了一个 int 列。

这对我来说没有意义，因为该表已经支持已存储在该表中的该卷的 int 数。

Answer 1

我找到了答案。问题是该表的设计数据类型实际上是一个 VarChar。 COALESCE 正在尝试输入一个 int。当它最终是一个varchar时。
