![]() ![]() VB.NET Code for SAP HANA Database Connection using ODBC in Visual Studio ![]() When I execute above code within my sample Visual Studio C# project, I got following outcome as result of the application. So I just wanted to show the two ways a column value can be read (either using column index or column name) Within the loop, first column value is fetched as well as TABLE_NAME column. Reads returning data set within in WHILE loop. TextBox1.Text = textBox1.Text rowData Ībove C-Sharp code connects to SAP HANA database. Using (OdbcDataReader reader = cmd.ExecuteReader()) "select top 3 * from \"PUBLIC\".\"M_TABLES\" where schema_name = ? ", "MYHDBUSER") Please do not confuse database name with catalog name ![]() If you don't know the database name, you can query M_DATABASES system view to find out the name of your HANA database. ServerNode details, the HANA Database server and port number was already used in the definition of the ODBC connection createad in SYSTEM DSN tab. ![]() Then define a string variable for connection string as follows: Within sample project code, first import namespace " " I have already described how to download SAP HANA Database Client and install for HDBODBC driver.Īfter SAP HANA Database Client is installed and a SYSTEM DSN is created via ODBC Data Sources, C-Sharp or VB.NET developers can continue with sample program code below. The related ODBC connection should be created using the HDBODBC driver which is provided by SAP. For using a shared memory connection it is required to set lpc: in front of the Server string.First of all, to connect to a SAP HANA Database developers should create a SYSTEM DSN entry.Īs I documented in tutorial Connect SAP HANA Database from SQL Server using Linked Server, programmers can define an ODBC connection with Data Sources (ODBC) from Administrative Tools. Your server has an ODBC interface and is enabled to (this depends on your ODBC driver installations)Īll connections only require the DatabaseName to be set by calling QSqlDatabase::setDatabaseName Open Connection using shared memory accessįor this option to work you will need to have access to memory of the machine and must have permissions to access shared memory.When trying to open a Database Connection with QODBC please ensure Opening MS SQL Server Database Connection using QODBC Therefor the client and the server itself will have to implement an interface to the ODBC layer. ODBC stands for Open Database Connectivity and provides an open API for DBMS access, where the ODBC layer acts as an transition layer. 3 Opening SAP HANA Database Connection using QODBC.2.1 Open Connection using shared memory access.2 Opening MS SQL Server Database Connection using QODBC. ![]()
