Question

我得到的錯誤「指定的參數太多」，但無法找到問題

任何幫助，將不勝感激

3個參數在開始的程序

的規定

DECLARE 
@WhereStatment nvarchar(500), 
@ParamList nvarchar(500) = N'@p1 int, @p2 varchar(256), @p3 int' 

SET @WhereStatment = '' 

-- Check for Status Filter 
IF @StatusFilter <> 'All' 
SET @WhereStatment = @WhereStatment + ' EntryStatus = @StatusFilter' 
ELSE 
BEGIN 
SET @StatusFilter = 'Invoiced (Complete)' 
SET @WhereStatment = @WhereStatment + ' EntryStatus <> @StatusFilter' 
END 

-- Check for User Filter 
IF @UserFilter > 0 
SET @WhereStatment = @WhereStatment + ' AND EobID = @UserFilter' 

-- Check for Warehouse Filter 
IF @WarehouseFilter > 0 
SET @WhereStatment = @WhereStatment + ' AND WarehouseNumber = @WarehouseFilter' 

-- Add WhereStatement 
Set @WhereStatment = ' 
SELECT 
tblWCS_SQE_Entries.RowID, SaleNum, tblWCS_Company_UserAccounts.Fullname, Ets 

FROM tblWCS_SQE_Entries 

INNER JOIN tblWCS_Company_UserAccounts 
ON tblWCS_SQE_Entries.EobID = tblWCS_Company_UserAccounts.RowID 

WHERE 
' 
+ @WhereStatment; 

EXEC sp_sqlexec @WhereStatment, @ParamList, 
       @p1 = @UserFilter, 
       @p2 = @StatusFilter, 
       @p3 = @WarehouseFilter 

Answer 1

sp_sqlexec存儲過程確實只有一個參數。相反，您可能需要sp_executesql。

Answer 2

DECLARE @SQL NVARCHAR(MAX) 

SET @SQL = ' 
SELECT tblWCS_SQE_Entries.RowID, SaleNum, tblWCS_Company_UserAccounts.Fullname, Ets 
FROM dbo.tblWCS_SQE_Entries 
JOIN dbo.tblWCS_Company_UserAccounts ON tblWCS_SQE_Entries.EobID = tblWCS_Company_UserAccounts.RowID 
WHERE ' 
+ CASE WHEN @StatusFilter = 'All' 
    THEN ' EntryStatus <> ''Invoiced (Complete)''' 
    ELSE ' EntryStatus = @StatusFilter' 
    END 
+ CASE WHEN @WarehouseFilter > 0 THEN ' AND WarehouseNumber = @WarehouseFilter' ELSE '' END 
+ CASE WHEN @UserFilter > 0 THEN ' AND EobID = @UserFilter' ELSE '' END 

EXEC sys.sp_executesql @SQL 
        , N'@p1 int, @p2 varchar(256), @p3 int' 
        , @p1 = @UserFilter 
        , @p2 = @StatusFilter 
        , @p3 = @WarehouseFilter
