[英]Confused Procedure or Function Has Too Many Arguments
好的,首先讓我為問一個看似多余的問題而道歉。 我正在嘗試優化存儲過程以及使用它的代碼。 我已經從代碼和存儲過程中獲取了所有參數,並將它們並排放置在 Excel 中,以計算每個參數中有多少。 兩者都有 23 個。 我認為有 1 個單個輸出參數可能會導致問題。 如果是這樣,我不確定如何處理它。
當我運行代碼時出現錯誤
System.Data.SqlClient.SqlException: 過程或函數 spr_SelectClaims 指定的參數過多。
存儲過程參數:
@BID int = NULL,
@IndID int = NULL,
@RecDateStart datetime = NULL,
@RecDateEnd datetime = NULL,
@ServiceTypeID int = NULL,
@Billed bit = NULL,
@Paid bit = NULL,
@Approved bit = NULL,
@Void bit = 0,
@LocationID int = NULL,
@BillingAgingDate datetime = NULL,
@PaymentAgingDate datetime = NULL,
@ClaimID int = NULL,
@Eligible bit = NULL,
@BillingTypeID int = NULL,
@ClaimDetailID int = NULL,
@SortExpression varchar(25) = NULL,
@ProvidedBy int = NULL,
@Billable varchar(10) = NULL,
@ExpenseOnly varchar(10) = NULL,
@PageIndex INT = NULL,
@PageSize INT = NULL,
@RecordCount INT OUTPUT
VB.NET 代碼
Dim helper As New DataBaseHelper(StoredProcedureName)
Dim _param As SqlParameter() = {
New SqlParameter("@RecordCount",SqlDbType.Int),
New SqlParameter("@BID", IIf(Me.BID Is Nothing, DBNull.Value, Me.BID)),
New SqlParameter("@IndID", IIf(Me.IndID Is Nothing, DBNull.Value, Me.IndID)),
New SqlParameter("@RecDateStart", IIf(Me.RecDate Is Nothing, DBNull.Value, Me.RecDate)),
New SqlParameter("@RecDateEnd", IIf(Me.RecDateEnd Is Nothing, DBNull.Value, Me.RecDateEnd)),
New SqlParameter("@ServiceTypeID", IIf(Me.ServiceTypeID Is Nothing, DBNull.Value, Me.ServiceTypeID)),
New SqlParameter("@Billed", IIf(Me.Billed Is Nothing, DBNull.Value, Me.Billed)),
New SqlParameter("@Paid", IIf(Me.Paid Is Nothing, DBNull.Value, Me.Paid)),
New SqlParameter("@Approved", IIf(Me.Approved Is Nothing, DBNull.Value, Me.Approved)),
New SqlParameter("@Void", IIf(Me.Void Is Nothing, DBNull.Value, Me.Void)),
New SqlParameter("@LocationID", IIf(Me.LocationID Is Nothing, DBNull.Value, Me.LocationID)),
New SqlParameter("@BillingAgingDate", IIf(Me.BillingAgingDate Is Nothing, DBNull.Value, Me.BillingAgingDate)),
New SqlParameter("@PaymentAgingDate", IIf(Me.PaymentAgingDate Is Nothing, DBNull.Value, Me.PaymentAgingDate)),
New SqlParameter("@Eligible", IIf(Me.Eligible Is Nothing, DBNull.Value, Me.Eligible)),
New SqlParameter("@BillingTypeID", IIf(Me.BillingTypeID Is Nothing, DBNull.Value, Me.BillingTypeID)),
New SqlParameter("@ClaimID", IIf(Me.ClaimID Is Nothing, DBNull.Value, Me.ClaimID)),
New SqlParameter("@ClaimDetailID", IIf(Me.ClaimDetailID Is Nothing, DBNull.Value, Me.ClaimDetailID)),
New SqlParameter("@SortExpression", IIf(sortExpresion Is Nothing, DBNull.Value, sortExpresion)),
New SqlParameter("@ProvidedBy", IIf(Me.ProvidedBy Is Nothing, DBNull.Value, Me.ProvidedBy)),
New SqlParameter("@Billable", IIf(billableonly Is Nothing, DBNull.Value, billableonly)),
New SqlParameter("@ExpenseOnly", IIf(expenseonly Is Nothing, DBNull.Value, expenseonly)),
New SqlParameter("@PageIndex", Me.PageIndex),
New SqlParameter("@PageSize", Me.PageSize)}
_param(0).Direction =ParameterDirection.Output
Dim dr As IDataReader = helper.RunDataReader(_param)
執行代碼
Public Function RunDataReader(ByVal parameters As SqlParameter()) As IDataReader
Dim dr As IDataReader
Dim sqlCommand As String = MyBase.StoredProcedureName
Dim dbCommand As DbCommand = db.GetStoredProcCommand(sqlCommand)
dbCommand.CommandTimeout = 160
If Not (parameters Is Nothing) Then
For Each param As SqlParameter In parameters
db.AddInParameter(dbCommand, param.ParameterName, param.DbType, param.Value)
Next param
End If
'HttpContext.Current.Response.Write(parameters.Length)
dr = db.ExecuteReader(dbCommand)
Return dr
End Function
好的,在進行了一些額外的挖掘之后,我發現由於某種原因,這 23 個參數最終變成了 92 個參數。 因此,解決此問題的方法可能是弄清楚為什么要嘗試將參數輸入 6 次。 有一個循環發生了 6 次,我知道那個循環是什么多虧 jmcilhinney 建議在 ExecuteReader 上放置一個斷點。 我能夠看到一個存儲過程被調用了 6 次。
