Stored Procedures as Data Sets

In SSRS, stored procedures can be used as a data source for reports. When a stored procedure is used as a data source, data sets are created from the result set returned by the stored procedure.

Syntax

The syntax for using a stored procedure as a data set in SSRS is as follows:

1. First, create a data source for the stored procedure.
2. Create a data set, using the stored procedure as the data source.
3. In the Query Designer, specify any input parameters for the stored procedure.

Example

Consider the following stored procedure, which returns a list of all orders:

CREATE PROCEDURE GetOrders
AS
BEGIN
    SELECT OrderID, CustomerID, OrderDate, ShipCountry
    FROM Orders
END

To use this stored procedure as a data set in SSRS, follow these steps:

1. Create a data source for the stored procedure in SSRS.
2. Create a new data set, using the stored procedure as the data source.
3. In the Query Designer, specify any input parameters for the stored procedure.
4. Save the data set.
5. Use the data set as the source for a report table.

Output

The output of the data set created from the stored procedure would be a table with the result set returned by the stored procedure, with the specified columns and rows.

Explanation

When a stored procedure is used as a data source in SSRS, a data set is created to hold the result set of the stored procedure. This is done by executing the stored procedure and returning the result set into the data set. Any input parameters that are required by the stored procedure can be specified in the Query Designer.

Use

Stored procedures can be useful as data sources in SSRS when there is complex processing or query logic that needs to be done on the database side. This can lead to faster performance and easier maintenance as the query logic can be changed in the stored procedure without having to modify the report itself.

Important Points

• Stored procedures used as data sources in SSRS must return a result set.
• Input parameters for the stored procedure can be specified in the Query Designer.
• Complex processing or query logic can be done on the database side using stored procedures as data sources.

Summary

Using stored procedures as data sources in SSRS can be a useful technique for creating reports. This allows complex processing or query logic to be performed on the database side and can lead to faster performance and easier maintenance. Stored procedures can be used as data sources in SSRS by creating a data source for the stored procedure and then creating a data set using the stored procedure as the data source. Input parameters for the stored procedure can be specified in the Query Designer.
