SAP Sybase SQL Anywhere
- 5 minutes to read
The Dashboard Designer allows you to connect to different types of SQL databases in the Data Source Wizard. You can also use data access API to connect to the database and select data in code.
This tutorial describes how to establish a connection to an SAP SQL Anywhere database and select data.
Important
The appropriate data provider must be installed on the client machine. For information on data providers, refer to the Data Sources article.
Create a Data Source in the Data Source Wizard
To connect to an SAP Sybase SQL Anywhere database in the Dashboard Designer, follow the steps below:
Click the New Data Source button in the Data Source ribbon tab.
On the first page of the invoked Data Source Wizard dialog, select SAP Sybase SQL Anywhere and click Next.
On the next page, choose the Server type. If you selected Server, the Data Source wizard displays the following connection settings:
|Hostname
Specifies the hostname of the SAP SQL Anywhere server to which the connection should be established.
Server name
Specifies the name of the SAP SQL Anywhere server to which the connection should be established.
User name
Specifies the user name used to authenticate to the SAP SQL Anywhere server.
Password
Specifies the password used to authenticate to the SAP SQL Anywhere server.
Database
Specifies the name of the database that contains data.
If you selected the Embedded Server type, the Data Source wizard displays the following connection settings:
Database
Specifies the path to the database that contains data. To locate the database, click the ellipsis button next to the Database field.
User name
Specifies the user name used to connect to the SAP SQL Anywhere database.
Password
Specifies the password used to connect to the SAP SQL Anywhere database.
Click Next and specify how to select data from the database.
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 tables/columns and passes the resulting SQL query to the SQL String editor. Subsequently, the text of the generated query returns to the Data Source wizard.
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.
Then click Next to specify the parameter settings.
On the final page, you can optionally add query parameters and preview data.
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 SQL Anywhere database, create an instance of the DashboardSqlDataSource class and follow the steps below:
Specify connection parameters for the SAP SQL Anywhere database. Create the AsaConnectionParameters class object and specify the following properties:
- Use the AsaConnectionParameters.Hostname property to specify the name of the server to which the connection should be established.
- Use the AsaConnectionParameters.ServerName property to specify the name of the server to which the connection should be established.
- Use the AsaConnectionParameters.DatabaseName property to specify the name of the database to which the connection should be established.
- Use the AsaConnectionParameters.UserName and AsaConnectionParameters.Password properties to specify user credentials.
Assign the resulting AsaConnectionParameters object to the SqlDataSource.ConnectionParameters property.
Note
Alternatively, you can add a connection string with parameters to the application configuration file. Then, assign the connection string name to the SqlDataSource.ConnectionName property.
Create one of the following objects to specify the query:
- Create a SelectQuery object to specify a set of tables/columns that form a SELECT statement when you execute a query.
- Create a CustomSqlQuery object to specify an SQL query. Use the CustomSqlQuery.Sql property to specify a custom query string.
- Create a StoredProcQuery object to execute a stored procedure call and supply the dashboard with data.
Add the created query to the SqlDataSource.Queries collection exposed by the DashboardSqlDataSource object.
- Add the created DashboardSqlDataSource object to the Dashboard.DataSources collection.
The following code snippet shows how to supply the dashboard with data from the Northwind database deployed on the SAP SQL Anywhere database server:
using DevExpress.DashboardCommon;
using DevExpress.DataAccess.ConnectionParameters;
using DevExpress.DataAccess.Sql;
// ...
AsaConnectionParameters asaParams = new AsaConnectionParameters();
asaParams.Hostname = "localhost";
asaParams.ServerName = "testserver";
asaParams.DatabaseName = "Northwind";
asaParams.UserName = "Admin";
asaParams.Password = "password";
DashboardSqlDataSource sqlDataSource = new DashboardSqlDataSource("Data Source 1", asaParams);
SelectQuery selectQuery = SelectQueryFluentBuilder
.AddTable("SalesPerson")
.SelectColumns("CategoryName", "Extended Price")
.Build("Query 1");
sqlDataSource.Queries.Add(selectQuery);
sqlDataSource.Fill();
dashboard.DataSources.Add(sqlDataSource);
