我想要總計45列中的43列。在表中它們被定義爲一個整數。選定列的總計數
Dim connStr, cmdStr As String
connStr = ConfigurationManager.ConnectionStrings("astsql").ConnectionString
cmdStr = "SELECT (SUM([index]),SUM([01]),SUM([02]),SUM([03]),SUM([04]),SUM([05]),SUM([06]),SUM([07]),SUM([08]),SUM([09]),SUM([10]),SUM([11]),SUM([12]),SUM([13]),SUM([14]),SUM([15]),SUM([16]),SUM([17]),SUM([18]),SUM([19]),SUM([20]),SUM([aa]),SUM([ab]),SUM([ac]),SUM([ad]),SUM([ae]),SUM([af]),SUM([ag]),SUM([ah]),SUM([ai]),SUM([aj]),SUM([ak]),SUM([al]),SUM([am]),SUM([an]),SUM([ao]),SUM([ap]),SUM([aq]),SUM([ar]),SUM([as]),SUM([at]),SUM([grsc]),SUM([grkr]),SUM([grkn])) FROM [count];"
Dim totalcount As Integer = 0
Dim n As Integer = 0
Try
Using conn As New SqlConnection(connStr)
Using cmd As New SqlCommand(cmdStr, conn)
conn.Open()
cmd.ExecuteNonQuery()
Using myreader = cmd.ExecuteReader()
While myreader.Read()
totalcount = totalcount + Convert.ToInt32(myreader(n))
n = n + 1
End While
End Using
conn.Close()
cmd.Dispose()
conn.Dispose()
End Using
End Using
Catch ex As Exception
Label5.Text = ex.ToString()
End Try
這裏是我的錯誤代碼:
System.Data.SqlClient.SqlException(0x80131904):附近有語法錯誤 ''。
