Набор параметров Где Динамически на хранимой процедуре

Question

У меня есть хранимая процедура поиска данных из базы данных с параметром, как это:

CREATE PROCEDURE [dbo].[Rintis_SearchPayment] 
    -- Add the parameters for the stored procedure here 
    @payIDin as int, 
    @PayAccountin as varchar(10), 
    @PayCustNamein as varchar(30), 
    @PayAmountin as int, 
    @PayAmountPaidin as int, 
    @PayResponsein as char (2), 
    @PayRefNoin as varchar (120), 
    @PayScreenTextin as varchar (100), 
    @PayReceiptTextin as varchar (350), 
    @PayDatetimein as datetime, 
    @PayBankCodein as varchar (6), 

    @payIDou as int, 
    @PayAccountou as varchar(10), 
    @PayCustNameou as varchar(30), 
    @PayAmountou as int, 
    @PayAmountPaidou as int, 
    @PayResponseou as char (2), 
    @PayRefNoou as varchar (120), 
    @PayScreenTextou as varchar (100), 
    @PayReceiptTextou as varchar (350), 
    @PayDatetimeou as datetime, 
    @PayBankCodeouin as varchar (6) 
AS 
BEGIN 
    -- SET NOCOUNT ON added to prevent extra result sets from 
    -- interfering with SELECT statements. 
    select @payIDou = PayId , 
      @PayAccountou = PayAccount, 
      @PayCustNameou = PayCustName, 
      @PayAmountou = PayAmount, 
      @PayAmountPaidou = PayAmountPaid, 
      @PayResponseou= PayResponse, 
      @PayRefNoou= PayRefNo, 
      @PayScreenTextou= PayScreenText, 
      @PayReceiptTextou= PayReceiptText, 
      @PayDatetimeou= PayDatetime, 
      @PayBankCodeouin= PayBankCode 
    from Payment 
    where PayId is not null AND 
      PayAccount like '%'+ISNULL((@PayAccountin),'')+'%' AND 
      PayCustName LIKE '%'+ISNULL((@PayAccountin),'')+'%' AND 
      PayAmount LIKE '%'+ISNULL((@PayAccountin),'')+'%' AND 
      PayAmountPaid LIKE '%'+ISNULL((@PayAccountin),'')+'%' AND 
      PayResponse LIKE '%'+ISNULL((@PayAccountin),'')+'%' AND 
      PayRefNo LIKE '%'+ISNULL((@PayAccountin),'')+'%' AND 
      cast(PayDatetime as date) = (select convert(date , ''+ISNULL((@PayAccountin),'')+'', 103)) order by PayDatetime DESC 

    select @payIDou 
    -- Insert statements for procedure here 
END 

но когда я исполняю его я не придавал значения, потому что я знаю, что некоторые, как неверно, поэтому он никогда не даст возвращаемого значения.

Сначала я сделать запрос, как это на моем VB .NET:

Public Function SearchPayment(ByVal PayAccount As String, ByVal PayCustName As String, ByVal PayAmount As String, ByVal PayAmountPaid As String, ByVal PayResponse As String, ByVal PayRefNo As String, ByVal PayDatetime As String) As Boolean 
     Dim strsql As String = " select top 100 * from Payment where PayId is not null " 
     If PayAccount <> "" Then 
      strsql &= "and PayAccount like '%" & PayAccount & "%'" 
     End If 
     If PayCustName <> "" Then 
      strsql &= "and PayCustName like '%" & PayCustName & "%'" 
     End If 
     If PayAmount <> "" Then 
      strsql &= "and PayAmount like '%" & PayAmount & "%'" 
     End If 
     '' add PayAmountPaid 
     If PayAmountPaid <> "" Then 
      strsql &= "and PayAmountPaid like '%" & PayAmountPaid & "%'" 
     End If 
     If PayResponse <> "" Then 
      strsql &= "and PayResponse like '%" & PayResponse & "%'" 
     End If 
     '' add PayRefNo 
     If PayRefNo <> "" Then 
      strsql &= "and PayRefNo like '%" & PayRefNo & "%'" 
     End If 
     If PayDatetime <> "" Then 
      ''select * from Inquiry where InquiryId is not null and cast(InquiryDate as date) = (select convert(date ,'7/05/2013' , 103)) 
      strsql &= "and cast(PayDatetime as date) = (select convert(date , '" & PayDatetime & "', 103)) " 
     End If 
     strsql &= "order by PayDatetime DESC" 
     Return runQuery(strsql) 

    End Function 

Можно ли добавить Where параметр путем проверки значения входного первого, как я сделал на моем vb.net?

Answer 1

Вы можете сделать это:

(@PayAccountin IS NULL OR 
PayAccount like '%'+ISNULL((@PayAccountin),'')+'%') AND 

Если параметр является недействительным, это будет верно и будет игнорировать состояние

Answer 2

Если вы можете изменить хранимую процедуру, самым простым решением было бы добавить проверку IS NULL в предложение WHERE. Somethin like:

select @payIDou = PayId , 
     @PayAccountou = PayAccount, 
     @PayCustNameou = PayCustName, 
     @PayAmountou = PayAmount, 
     @PayAmountPaidou = PayAmountPaid, 
     @PayResponseou= PayResponse, 
     @PayRefNoou= PayRefNo, 
     @PayScreenTextou= PayScreenText, 
     @PayReceiptTextou= PayReceiptText, 
     @PayDatetimeou= PayDatetime, 
     @PayBankCodeouin= PayBankCode 
from Payment 
where PayId is not null AND 
     ((PayAccount like '%'+ @PayAccountin+'%') OR @PayAccountin IS NULL) AND 
     ((PayCustName LIKE '%'+ @PayAccountin+'%') OR @PayAccountin IS NULL) AND... //the rest of your WHERE clause 

Это эффективно игнорирует аргументы, которые передаются как NULL. Надеюсь, я правильно понял ваш вопрос.

Возможного это будет полезно для вас -

CREATE PROCEDURE [dbo].[Rintis_SearchPayment] 

@payIDin AS INT, 
... 

AS 
BEGIN 

    SET NOCOUNT ON; 

    SELECT @payIDou = PayId , 
      @PayAccountou = PayAccount, 
      @PayCustNameou = PayCustName, 
      @PayAmountou = PayAmount, 
      @PayAmountPaidou = PayAmountPaid, 
      @PayResponseou= PayResponse, 
      @PayRefNoou= PayRefNo, 
      @PayScreenTextou= PayScreenText, 
      @PayReceiptTextou= PayReceiptText, 
      @PayDatetimeou= PayDatetime, 
      @PayBankCodeouin= PayBankCode 
    FROM dbo.Payment 
    WHERE PayId IS NOT NULL 
     AND (
      @PayAccountin IS NULL 
      OR 
       (
         PayAccount LIKE '%' + @PayAccountin + '%' 
        AND PayCustName LIKE '%' + @PayAccountin + '%' 
        AND PayAmount LIKE '%'+ @PayAccountin +'%' 
        AND PayAmountPaid LIKE '%' + @PayAccountin +'%' 
        AND PayResponse LIKE '%'+ @PayAccountin + '%' 
        AND PayRefNo LIKE '%'+ @PayAccountin + '%' 
       ) 
     ) 
     AND (
       @PayAccountin IS NULL 
      OR 
       CAST(PayDatetime AS DATE) = CONVERT(DATE , @PayAccountin, 103) 
     ) 
    ORDER BY PayDatetime DESC 

    SELECT @payIDou 

END 

Answer 4

Thank You Для вашего Respon, но я нашел другое решение, используя sp_Executesql и более эффективно:

Create Procedure SearchPaymentDev 



    @PayAccountin as varchar(10), 
    @PayCustNamein as varchar(30), 
    @PayAmountin as int, 
    @PayAmountPaidin as int, 
    @PayResponsein as char (2), 
    @PayRefNoin as varchar (120), 
    @PayScreenTextin as varchar (100), 
    @PayReceiptTextin as varchar (350), 
    @PayDatetimein as datetime, 
    @PayBankCodein as varchar (6), 


AS 
    Set NoCount ON 
    /* Variable Declaration */ 
    Declare @SQLQuery AS NVarchar(4000) 
    Declare @ParamDefinition AS NVarchar(2000) 
    /* Build the Transact-SQL String with the input parameters */ 
    Set @SQLQuery = 'Select * From payment where PayId is not null ' 
    /* check for the condition and build the WHERE clause accordingly */ 
    If @PayAccountin Is Not Null 
     Set @SQLQuery = @SQLQuery + ' And (PayAccount = @PayAccountin)' 

    If @PayCustNamein Is Not Null 
     Set @SQLQuery = @SQLQuery + ' And (PayCustName = @PayCustNamein)' 

    If @PayAmountin Is Not Null 
     Set @SQLQuery = @SQLQuery + ' And (PayAmount = @PayAmountin)' 

    If @PayAmountPaidin Is Not Null 
     Set @SQLQuery = @SQLQuery + ' And (PayAmountPaid = @PayAmountPaidin)' 

    --If (@StartDate Is Not Null) AND (@EndDate Is Not Null) 
    --  Set @SQLQuery = @SQLQuery + ' And (JoiningDate 
    --  BETWEEN @StartDate AND @EndDate)' 
    /* Specify Parameter Format for all input parameters included 
    in the stmt */ 
    Set @ParamDefinition =  '@PayAccountin as varchar(10), 
       @PayCustNamein as varchar(30), 
       @PayAmountin as int, 
       @PayAmountPaidin as int' 
    /* Execute the Transact-SQL String with all parameter value's 
     Using sp_executesql Command */ 
    Execute sp_Executesql  @SQLQuery, 
       @ParamDefinition, 
       @PayAccountin, 
       @PayCustNamein, 
       @PayAmountin, 
       @PayAmountPaidin 

    If @@ERROR <> 0 GoTo ErrorHandler 
    Set NoCount OFF 
    Return(0) 

ErrorHandler: 
    Return(@@ERROR) 
GO
