Question

I’m trying my first dynamic sql stored procedure. I need to append the exact same records into multiple tables with the same column names. What I have compiles, but when it runs I get ‘invalid column name ‘TradeDate. The driver sproc is first below, then the sproc containing the dynamic statement. If anyone could help, that’d be great..

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

You’re missing a space after the “FROM” in this line:

FROM' + @tableName +

Should be

FROM ' + @tableName +

Otherwise it’s going to try running SELECT FROMTABLE.
