In many JDBC applications, you'll probably want to do something else with the results, such as displaying them in a table or grid in a GUI applet or application. Notice that in this example all we're doing is printing our results. In the case of our sample database, the printed results look like this:īecause these are the last names of the two customer records where Snum equals 2001. This loop reads the last name returned in each record, and prints it to the screen using the normal () method. After the previous two lines, you might add a loop like this to read the results: In many cases, you can just use the next() method of the ResultSet object. Reading the JDBC SELECT query results (i.e., a Java JDBC ResultSet)Īfter you execute the SQL query, how do you read the results? Well, JDBC makes this pretty easy also. The ResultSet object rs now contains the results from the database query. That's really just an intermediate step that lets us do what we want to do in the next step: Execute our query, and get a ResultSet object. In the first step, I create a Java Statement objection from the Connection object. ResultSet rs = stmt.executeQuery("SELECT Lname FROM Customers WHERE Snum = 2001") Here's the JDBC code necessary to create and execute this query: Now that we know the information we want to retrieve, how do we put this SQL statement into a Java program? It's actually very simple. In plain English, you might say "give me the last name of every customer where the salesperson id-number is 2001". This statement returns each Lname (last name) record from the Customers database, where Snum (salesperson id-number) equals 2001. To demontrate this I’ll write this simple SQL SELECT query: The hardest part of the process is defining the query you want to run, and then writing the code to read and manipulate the results of your SELECT query. Execute the SQL SELECT query you want to run.Querying a SQL database with JDBC is typically a three-step process: MySQL with Java in Eclipse fig -6 Now right click on the project and create a new Java class ( New>Class ). MySQL with Java in Eclipse fig -5 Now give a name to your project ( DbConnect in this example) and click on Finish. (I populated that data in my JDBC SQL INSERT tutorial.) How to perform a JDBC SELECT query against a database Open Eclipse IDE and click on the Java Project under the new section of File Menu (File>New>Java Project). jar using the -cp argument in the Java command line you use to start your Java command line.As you can see, the Customers table contains these four sample records. Specify the directory containing the JDBC.jar file to the CLASSPATH environment variable (see Modifying the Java CLASSPATH). Also, these courses are the most popular courses in their respective categories. These courses have received rave 5 star reviews and over 60,000 students have taken the courses. Java Database Connection (JDBC) JavaServer Faces (JSF) for Beginners. Add the directory containing the JDBC. My first three courses on Udemy were: Eclipse IDE for Beginners.You know, in order for Java applications working with a database engine via Java Database Connectivity (JDBC), an appropriate JDBC driver library is required to be available in the application’s classpath.

jar file you downloaded to either the system-wide Java Extensions folder ( /Library/Java/Extensions) or your user Java Extensions folder ( /Users/ username /Library/Java/Extensions). This post lists resources to download JDBC drivers for common databases, for your reference in database programming with Java. Choose one of these methods to tell the Java interpreter where to look for the library: In order for your Java client application to use the Vertica JDBC driver, the Java interpreter needs to be able to find its library file.
