Introduction

When working with SQL Server Reporting Services (SSRS) 2008, handling multiple result sets from a stored procedure can be a challenging task. In this article, we will discuss the best practices for handling multiple result sets from a stored procedure in SSRS 2008.

Understanding Multiple Result Sets

A stored procedure can return multiple result sets, which are essentially multiple tables of data. Each result set can have a different structure and can be used to display different types of data. In SSRS 2008, you can use the stored procedure as a data source and then use the result sets to create multiple tables or matrices in your report.

Benefits of Handling Multiple Result Sets

Handling multiple result sets from a stored procedure in SSRS 2008 offers several benefits, including:

Improved data organization: By using multiple result sets, you can organize your data in a more logical and structured way, making it easier to analyze and understand.
Increased flexibility: Multiple result sets allow you to display different types of data in the same report, making it more flexible and adaptable to changing business needs.
Reduced complexity: By using a single stored procedure to return multiple result sets, you can reduce the complexity of your report and make it easier to maintain.

Best Practices for Handling Multiple Result Sets

When handling multiple result sets from a stored procedure in SSRS 2008, follow these best practices:

1. Use a Single Stored Procedure

Use a single stored procedure to return multiple result sets. This approach simplifies the report design and reduces the complexity of the report.

2. Use a Common Data Source

Use a common data source for all result sets. This approach ensures that all result sets are based on the same data and makes it easier to manage the report.

3. Use a Data Set for Each Result Set

Use a data set for each result set. This approach allows you to handle each result set separately and makes it easier to manage the report.

4. Use a Matrix or Table for Each Result Set

Use a matrix or table for each result set. This approach allows you to display each result set in a separate table or matrix, making it easier to analyze and understand the data.

5. Use Parameters to Filter Data

Use parameters to filter data in each result set. This approach allows you to filter the data based on user input and makes it easier to manage the report.

6. Use a Common Layout for All Result Sets

Use a common layout for all result sets. This approach ensures that all result sets have a consistent layout and makes it easier to manage the report.

7. Use a Data Region for Each Result Set

Use a data region for each result set. This approach allows you to display each result set in a separate data region, making it easier to analyze and understand the data.

8. Use a Common Header and Footer for All Result Sets

Use a common header and footer for all result sets. This approach ensures that all result sets have a consistent header and footer and makes it easier to manage the report.

Example of Handling Multiple Result Sets

Suppose you have a stored procedure that returns four result sets of related data. Each result set has a different structure and can be used to display different types of data. To handle multiple result sets in SSRS 2008, follow these steps:

Create a new report: Create a new report in SSRS 2008 and add a data source to the report.
Use a stored procedure as a data source: Use the stored procedure as a data source for the report.
Use a data set for each result set: Use a data set for each result set. This approach allows you to handle each result set separately and makes it easier to manage the report.
Use a matrix or table for each result set: Use a matrix or table for each result set. This approach allows you to display each result set in a separate table or matrix, making it easier to analyze and understand the data.
Use parameters to filter data: Use parameters to filter data in each result set. This approach allows you to filter the data based on user input and makes it easier to manage the report.
Use a common layout for all result sets: Use a common layout for all result sets. This approach ensures that all result sets have a consistent layout and makes it easier to manage the report.
Use a data region for each result set: Use a data region for each result set. This approach allows you to display each result set in a separate data region, making it easier to analyze and understand the data.
Use a common header and footer for all result sets: Use a common header and footer for all result sets. This approach ensures that all result sets have a consistent header and footer and makes it easier to manage the report.

Conclusion

Handling multiple result sets from a stored procedure in SSRS 2008 offers several benefits, including improved data organization, increased flexibility, and reduced complexity. By following the best practices outlined in this article, you can create a report that effectively handles multiple result sets and provides valuable insights to users.

Best Practices for Testing and Deployment

When testing and deploying a report that handles multiple result sets, follow these best practices:

1. Test the report thoroughly

Test the report thoroughly to ensure that it handles multiple result sets correctly.

2. Use a test environment

Use a test environment to test the report before deploying it to production.

3. Use a deployment plan

Use a deployment plan to ensure that the report is deployed correctly and that all dependencies are met.

4. Use a rollback plan

Use a rollback plan to ensure that the report can be rolled back to a previous version if necessary.

5. Use a change management process

Use a change management process to ensure that all changes to the report are properly documented and approved.

By following these best practices, you can ensure that your report is properly tested and deployed, and that it provides valuable insights to users.

Common Issues and Solutions

When handling multiple result sets from a stored procedure in SSRS 2008, you may encounter the following common issues and solutions:

1. Error: "Multiple result sets are not supported"

Error: "Multiple result sets are not supported"

Solution: Use a data set for each result set and use a matrix or table for each result set.

2. Error: "Data set is not defined"

Error: "Data set is not defined"

Solution: Define a data set for each result set and use a data region for each result set.

3. Error: "Parameter is not defined"

Error: "Parameter is not defined"

Solution: Define a parameter for each result set and use it to filter data.
