SAP Sybase ASE

  • 4 min to read

Invoke the Data Source Wizard to create a data source, connect to the database and select the data. Another option is the API that allows you to perform the same tasks in code.

Important

The appropriate data provider must be installed on the client machine. For information on data providers, refer to the Supported Data Sources article.

Create a Data Source in the Data Source Wizard

To connect to the SAP Sybase ASE database in the Dashboard Designer, perform the following steps.

  1. Click the New Data Source button in the Data Source ribbon tab.

    DataBinding_NewDataSource

  2. On the first page of the invoked Data Source Wizard dialog, select Database and click Next.

    DataSourceWizard_Database

  3. On the next page, select the SAP Sybase ASE data provider and specify the connection parameters.

    DataSourceWizard_SAPSybaseASE

    • Server name

      Specifies the name of the SAP Sybase ASE database server to which the connection should be established.

    • User name

      Specifies the user name used to authenticate to the SAP Sybase ASE database server.

    • Password

      Specifies the password used to authenticate to the SAP Sybase ASE database server.

    • Database

      Specifies the name of the database that contains the required data.

      Tip

      To specify the port number or other additional parameters, change Provider to Custom connection string and type in the connection string that contains the parameters.

  4. Click Next and specify how to select data from the database.

    DataSourceWizard_Query

    You can choose from the following options:

    • Select the Query option and click Run Query Builder... to invoke the Query Builder. The Query Builder allows you to choose the required tables/columns visually and passes the resulting SQL query to the SQL String editor. Subsequently, the text of the generated query returns to the Data Source wizard.

      DataSourceWizard_GeneratedQuery

      Click Finish to create the data source.

      Note

      If you apply filtering or use query parameters, click Next to specify the parameter settings.

    • Select the Stored Procedure option to select one of the stored procedures from the database.

      DataSourceWizard_SelectStoredProcedure

      Then click Next to specify the parameter settings.

  5. On the final page, you can optionally add query parameters and preview data.

    DataSourceWizard_AddQueryParameters

    Click Finish to create the data source.

Create a Data Source in Code

To create a data source that uses a connection to the SAP Sybase ASE database, create the instance of the DashboardSqlDataSource class and perform the following steps.

  1. Specify connection parameters to the SAP Sybase ASE database. Create the AseConnectionParameters class instance and specify the following properties:

    • ServerName property to specify the name of the server to which the connection should be established.
    • DatabaseName property to specify the name of the database to which the connection should be established.
    • UserName and Password properties to specify user credentials.

    Assign the resulting AseConnectionParameters object to the DashboardSqlDataSource.ConnectionParameters property.

    Note

    As an alternative, you can add a connection string with required parameters to the application configuration file. Then, assign the connection string name to the SqlDataSource.ConnectionName property.

  2. Create one of the following query objects to retrieve data:

    • The SelectQuery object allows you to specify a set of tables/columns, which form a SELECT statement when executing a query.
    • The CustomSqlQuery object allows you to specify an SQL query manually.
    • The StoredProcQuery object allows you to perform a stored procedure call to supply the dashboard with data.

    Add the created query to the DashboardSqlDataSource.Queries collection.

  3. Add the created DashboardSqlDataSource object to the Dashboard.DataSources collection.

The following code snippet shows how to supply the dashboard with data from the SAP Sybase ASE database.

using DevExpress.DashboardCommon;
using DevExpress.DataAccess.ConnectionParameters;
using DevExpress.DataAccess.Sql;
// ...
            AseConnectionParameters aseParams = new AseConnectionParameters();
            aseParams.ServerName = "localhost";
            aseParams.DatabaseName = "Northwind";
            aseParams.UserName = "Admin";
            aseParams.Password = "password";            

            DashboardSqlDataSource sqlDataSource = new DashboardSqlDataSource("Data Source 1", aseParams);
            SelectQuery selectQuery = SelectQueryFluentBuilder
                .AddTable("SalesPerson")
                .SelectColumns("CategoryName", "Extended Price")
                .Build("Query 1");
            sqlDataSource.Queries.Add(selectQuery);
            sqlDataSource.Fill();
            dashboard.DataSources.Add(sqlDataSource);
