Update Query In Java Netbeans
Table of Contents.Java JDBC FAQ: Can you share an example of a SQL SELECT query using the standard JDBC syntax?In I showed how to connect your Java applications to standard SQL databases like MySQL, SQL Server, Oracle, SQLite, and others using. In those examples I showed how to connect to two different databases so you could see how little the code changes when you switch from one database to another.In this SELECT query tutorial I'll take JDBC to the next step, showing how to create and execute a SQL SELECT statement in your Java code. JDBC SELECT query: A sample databaseBefore looking at the SQL queries, let's take a quick look at our sample database.In all of these examples I’ll access a database named 'Demo', and in these SELECT query examples I’ll access a database table named 'Customers' that's contained in the Demo database.Here's what the Customers table looks like. Download our example JDBC select programIf you're interested, you can. You can test this JDBC example code on your own system, but note that you'll need to change the lines where we create our url and conn objects to reflect your own database configuration.

ConclusionQuerying an SQL database with JDBC is a simple three step process, once you know how to do it. Just (1) create a ResultSet object, (2) execute the query, and then (3) read the results.

Hi Alvin,as from your code snippet.ResultSet rs = conn.createStatement;st.executeQuery('select Lname from Customers where Snum = 2001');dont u think this code is never going to execute.it wont compile first of allbecause conn.createStatement returs a Statement and not a ResultSet.you will get a ResultSet only at line no 2 when you do st.executeQuery(String sql).let me know your thoughts!RegardsRakesh.Submitted by on February 12, 2010 - 11:01amIn reply to by Rakesh (not verified).
