我有一行代码在 MS Access 中创建了一个产生错误的 CrossTab 查询。
这是代码:
Dim cmd4 As OleDbCommand = New OleDbCommand("TRANSFORM First(y.Daily_Growth) AS FirstOfDaily_Growth Select y.Ticker FROM Daily_Growth_Rates AS y GROUP BY y.Ticker ORDER BY y.[Date] DESC PIVOT y.[Date]", Nordeen_Investing_3.con)
这是错误:
Additional information: Too many crosstab column headers (7326).
我究竟做错了什么?
