Question

我正在尝试我的第一个动态sql存储过程。我需要将完全相同的记录追加到具有相同列名的多个表中。我编译的内容，但是当它运行时，我得到'无效的列名'TradeDate。驱动程序sproc首先在下面，然后是包含动态语句的sproc。如果有人可以提供帮助，那就太好了..

ALTER PROCEDURE dbo.StoredProcedure2

AS

DECLARE @tableName varchar(120)
SET @tableName = 'tblDailyATR'
EXEC sprocAddDatesAndSymbolsToAggregatedStudy @tableName

RETURN

ALTER PROCEDURE dbo.sprocAddDatesAndSymbolsToAggregatedStudy
    @table varchar(120)

AS

DECLARE @tableName varchar(120)
SET @tableName = @table

EXEC(
'INSERT INTO ' + @tableName + '(Symbol, TradeDate)
SELECT Symbol, TradingDate
FROM (SELECT tblSymbolsMain.Symbol, tblTradingDays.TradingDate
      FROM tblSymbolsMain CROSS JOIN tblTradingDays
      WHERE (tblTradingDays.TradingDate <= dbo.NextAvailableDataDownloadDate())) AS T1
      WHERE (NOT EXISTS (SELECT TradeDate, Symbol
      FROM' + @tableName +
      ' WHERE (TradeDate = T1.TradingDate) AND (Symbol = T1.Symbol)))')

RETURN

Answer 1

你在这一行的“FROM”后遗漏了一个空格：

FROM' + @tableName +

应该是

FROM ' + @tableName +

否则它将尝试运行SELECT FROMTABLE。

动态sql插入返回'无效列名'
