Once the download is complete, just unzip the file and run the setup.exe file. This Oracle JDBC example requires Oracle Database XE (Express edition) which can be downloaded from the following link.Īccept the license agreement and download the version for the required platform. With Type 4 drivers, the user needs a different driver for each database.
#Oracle jdbc thin client hangs bastian server drivers
Type 4 JDBC drivers don’t have to translate database requests to ODBC or a native connectivity interface or to pass the request on to the another server. The number of translation layers is very less i.e.Further, these drivers can be downloaded dynamically. No special software is required either on the client or the server side.The major benefit of using a Type 4 JDBC driver is that they are completely written in Java to achieve platform independence and eliminate deployment administration issues.Since ODBC drivers are entirely written in C language, therefore, they are platform dependent and cause the portability issues. ODBC API uses ODBC Drivers to interact with the databases. String name = resObj.getString("test_name ") įloat salary = resObj.getFloat("test_salary ") īefore JDBC, ODBC API was used to communicate with the databases. ResultSet resObj = stmtObj.executeQuery("SELECT test_id, test_name, test_salary FROM testTable") Statement stmtObj = connObj.createStatement() The following simple code fragment gives an example of these three steps,Įxample.java Connection connObj = DriverManager.getConnection("jdbc:myDriver:testDb", "myLoginId", "myPassword") Retrieving and processing the results received from the database in answer to the SQL query.Sending queries and update statements to the database.JDBC lets a developer manage the below three important programming activities, i.e.: 1: Java Database Connectivity (JDBC) Architecture
