Hi,

I have a stored procedure e.g

Create StoredProcedure ABC
@ID INT,
@myDate DATE
AS
Begin
Select FirstName,LastName,(Select SUM(Salary) from t2 where t2.paymentDate=@myDate And t2.ID=@ID) from t1 Where t1.ID=@ID
END
============================

Now my question is how to set stored procedure as crystal report data source and then how to pass parameter array to crystal report or stored procedure?

Thanks,

The SP as is wont work with array or string of values as it expects parameter of a specific type (in your case int and date).

In the SP you need to accept a string where you expect to pass an array. Normally the string would be "," saperated.

Create a #Temptable and write a code to put every single vale in that table.

later join that #TempTable to the query.

to setup your report with SP please see this

See an example SQL below:

in that code, it parses the "," saperated string and put the values in the #TempTable within the SP. But you can also write a UDF to parse the string and return a table. It will be just another way.
CREATE PROC dbo.GetOrderList2
(
	@OrderList varchar(500)
)
AS
BEGIN
	SET NOCOUNT ON

	CREATE TABLE #TempList
	(
		OrderID int
	)

	DECLARE @OrderID varchar(10), @Pos int

	SET @OrderList = LTRIM(RTRIM(@OrderList))+ ','
	SET @Pos = CHARINDEX(',', @OrderList, 1)

	IF REPLACE(@OrderList, ',', '') <> ''
	BEGIN
		WHILE @Pos > 0
		BEGIN
			SET @OrderID = LTRIM(RTRIM(LEFT(@OrderList, @Pos - 1)))
			IF @OrderID <> ''
			BEGIN
				INSERT INTO #TempList (OrderID) VALUES (CAST(@OrderID AS int)) --Use Appropriate conversion
			END
			SET @OrderList = RIGHT(@OrderList, LEN(@OrderList) - @Pos)
			SET @Pos = CHARINDEX(',', @OrderList, 1)

		END
	END	

	SELECT o.OrderID, CustomerID, EmployeeID, OrderDate
	FROM 	dbo.Orders AS o
		JOIN 
		#TempList t
		ON o.OrderID = t.OrderID
		
END

Normally the Reporting Tools (Crystal, SSRS etc) pass the multiple value parameters as a "," saperated string. you need is to setup your report to call that SP passing the multiple value parameters to it.

Here is the little exract from the link I posted before to setup your report with SP:
When creating a Crystal Report, make it like any other report, except for the following.
1. When specifying a data source, instead of selecting Tables or Views, select Procedures, and then select the newly created procedure.
2. Crystal will immediately prompt you to enter values for the procedure’s input parameters. Do NOT do so; rather, check “Set as Null” and click OK so Crystal will know to prompt for these as input parameters each time the report is run.
3. If you are using SQLServer, click on the Field Explorer and rename the fields to remove the “@” prefix that Crystal automatically adds to conform to SQLServer parameter/variable naming conventions

To call it in SQL Server, go:
execute GetOrderList2("1, 3, 8 , 9, 30, 22, 89 ")
assuming we wnated results for order ids 1, 3, 8 , 9, 30, 22 and 89

Hope it will help
