Azure SQL Connection Type (SSRS)
Microsoft Azure SQL Database is a cloud-based, hosted relational database built on SQL Server technologies. To include data from SQL Database in your report, you must have a dataset that is based on a report data source of type SQL Database. This built-in data source type is based on the SQL Database data extension. Use this data source type to connect to and retrieve data from SQL Database.
This data extension supports multivalued parameters, server aggregates, and credentials managed separately from the connection string.
SQL Database is similar to an instance of SQL Server on your premises and getting data from SQL Database is, with a few exceptions, identical to getting data from SQL Server.
When opening a connection to a SQL Database, set the connection timeout to 30 seconds.
For more information, see Microsoft Azure SQL Database.
Use the information in this topic to build a data source. For step-by-step instructions, see Add and Verify a Data Connection (Report Builder and SSRS).
When you connect to SQL Database, you're connecting to a database object in the cloud. Just like onsite databases, the hosted database might have multiple schemas that have multiple tables, views, and stored procedures. You specify the database object to use in the query designer. If you don't specify a database in the connection string, you connect to the default database that the administrator assigned to you.
Contact your database administrator for connection information and for the credentials to use to connect to the data source. The following connection string example specifies a hosted sample database named AdventureWorks.
Data Source=<host>;Initial Catalog=AdventureWorks; Encrypt=True;
Also, you use the Data Sources Properties dialog box to provide credentials such as user name and password. The
User Id and
Password options are automatically appended to the connection string; you don't need to type them as part of the connection string.
For more information and connection string examples, see Create data connection strings - Report Builder & SSRS.
Windows Authentication (integrated security) isn't supported. If you attempt to connect to SQL Database using Windows Authentication an error occurs. SQL Database supports only SQL Server Authentication (user name and password) and users must provide credentials (login and password) every time they connect to SQL Database.
Credentials must be sufficient to access the database. Depending on your query, you might need other permissions, such as sufficient permissions to run stored procedures and access tables and views. The owner of the external data source must configure credentials that are sufficient to provide read-only access to the database objects that you need.
From a report authoring client, the following options are available to specify credentials:
Use a stored user name and password. To negotiate the double hop that occurs when the database that contains the report data is different than the report server, select options to use credentials as Windows credentials. You can also choose to impersonate the authenticated user after connecting to the data source.
No credentials are required. To use this option, you must have the unattended execution account configured on the report server. For more information, see Configure the Unattended Execution Account (Report Server Configuration Manager).
For more information, see Create data connection strings - Report Builder & SSRS or Specify Credential and Connection Information for Report Data Sources.
A query specifies which data to retrieve for a report dataset. The columns in the result set for a query populate the field collection for a dataset. If the query returns multiple result sets, the report processes only the first result set that the query retrieves. Although there are some differences between SQL Server and SQL Databases such as the sizes of databases supported, writing queries against SQL Databases is similar to writing queries against SQL Server databases. Some Transact-SQL statements such as BACKUP aren't supported in SQL Database, but they aren't ones that you use in report queries. For more information, see SQL Server Connection Type (SSRS).
By default, if you create a new query or open an existing query that can be represented in the graphical query designer, the relational query designer is available. You can specify a query in the following ways:
Build a query interactively. Use the relational query designer that displays a hierarchical view of tables, views, stored procedures, and other database items, organized by the database schema. Select columns from tables or views, or specify stored procedures or table-valued functions. Limit the number of rows of data to retrieve by specifying filter criteria. Customize the filter when the report runs by setting the parameter option.
Type or paste a query. Use the text-based query designer to enter Transact-SQL text directly, to paste query text from another source, to enter complex queries that cannot be built by using the relational query designer or to enter query-based expressions.
Import an existing query from a file or report. Use the Import query button from either query designer to browse to a .sql file or .rdl file and import a query.
The text-based query designer supports the following two modes:
Text Type Transact-SQL commands that select data from the data source.
Stored Procedure Choose from a list of stored procedures.
For more information, see Relational Query Designer User Interface (Report Builder) and Text-based Query Designer User Interface (Report Builder).
The graphical query designer that SQL Database uses provides built-in support for grouping and aggregates to help you write queries that retrieve only summary data. The Transact-SQL language features are: the GROUP BY clause, DISTINCT keyword, and aggregates such as SUM and COUNT. The text-based query designer provides full support for the Transact-SQL language, including grouping and aggregates. For more information about Transact-SQL, see Transact-SQL Reference (Database Engine).
Using Query Type Text
In the text-based query designer, you type Transact-SQL commands to define the data in a dataset. For example, the following Transact-SQL query selects the names of all employees who are marketing assistants:
SELECT HumanResources.Employee.BusinessEntityID ,HumanResources.Employee.JobTitle ,Person.Person.FirstName ,Person.Person.LastName FROM Person.Person INNER JOIN HumanResources.Employee ON Person.Person.BusinessEntityID = HumanResources.Employee.BusinessEntityID WHERE HumanResources.Employee.JobTitle = 'Marketing Assistant'
Click the Run button (!) on the toolbar to run the query and display a result set.
To parameterize this query, add a query parameter. For example, change the WHERE clause to the following:
WHERE HumanResources.Employee.JobTitle = (@JobTitle)
When you run the query, report parameters that correspond to query parameters are automatically created. For more information, see Query Parameters later in this topic.
Using Query Type StoredProcedure
You can specify a stored procedure for a dataset query in one of the following ways:
In the Dataset Properties dialog box, set the Stored Procedure option. Choose from the drop-down list of stored procedures and table-valued functions.
In the relational query designer, in the Database view pane, select a stored procedure or table-valued function.
In the text-based query designer, select StoredProcedure from the toolbar.
After you select a stored procedure or table-valued function, you can run the query. You then are prompted for input parameter values. When you run the query, report parameters that correspond to input parameters are automatically created. For more information, see Query Parameters later in this topic.
Only the first result set that is retrieved for a stored procedure is supported. If a stored procedure returns multiple result sets, only the first one is used.
If a stored procedure has a parameter that has a default value, you can access that value by using the DEFAULT keyword as a value for the parameter. If the query parameter is linked to a report parameter, the user can type or select the word DEFAULT in the input box for the report parameter.
For more information about stored procedures, see Stored Procedures (Database Engine).
When query text contains query variables or stored procedures that have input parameters, the corresponding query parameters for the dataset and report parameters for the report are automatically generated. The query text must not include the DECLARE statement for each query variable.
For example, the following SQL query creates a report parameter named EmpID:
SELECT FirstName, LastName FROM HumanResources.Employee E INNER JOIN Person.Contact C ON E.ContactID=C.ContactID WHERE EmployeeID = (@EmpID)
By default, each report parameter has data type Text and an automatically created dataset to provide a drop-down list of available values. After the report parameters are created, you might have to change default values. For more information, see Report Parameters (Report Builder and Report Designer).
Alternate Data Extensions
You can also retrieve data from a SQL Server database by using an ODBC data source type. Connecting to SQL Database by using OLE DB isn't supported.
For more information, see ODBC Connection Type (SSRS).
Platform and Version Information
For more information about platform and version support, see Data Sources Supported by Reporting Services (SSRS).
Azure SQL Database and AAD
You can use the Azure SQL database with Azure Active Directory (AAD).
This scenario is supported when you set up the following items properly:
- Active Directory Authentication Library for SQL Server (ADALSQL) is installed on the report server.
- Active Directory Federation Services (ADFS) is configured to federate across on-premises Active Directory (AD) and AAD.
- Kerberos Constrained Delegation (KCD) is configured from the report server to the ADFS server.
- Configure the report/data source to authenticate to Azure SQL Database as the user viewing the report.
