JDBC connection to Microsoft Access in Windows 7
Introduction - In this article we make a connection using JDBC to a Microsoft Access database. This connection is made with the help of a JdbcOdbc driver. You need to use the following steps for making the connection to the data base.
Creating a Database
Step 1 : Open Microsoft Access and select Blank data base option and give the data base name as File name option
Step 2 : Create a table and insert your data into the table
Step 3 : Save the table with the desired name; in this article we save the following records with the table name student.
Now Creating DSN of your data base
Step 4 : Open your Control Panel and than select Administrative Tools.
Step 5 : Click on Data Source(ODBC)-->System DSN.
Step 6 : Now click on add option for making a new DSN.select Microsoft Access Driver (*.mdb. *.accdb) and than click on Finish
Step 7 : Make your desired Data Source Name and then click on the Select option, for example in this article article we us the name mydsn
Step 8 : Now you select your data source file for storing it and then click ok and then click on Create and Finish
Step 9 : Java program code
import java.sql.*;
public class MsAcessODBC
{
public static void main(String[] args)
{
try
{
// loading thejdbc odbc driver
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
// creating connection toth data base
Connection con = DriverManager.getConnection("jdbc:odbc:mydsn","","");
Statement st = con.createStatement();
// create an execute sql command on database
ResultSet rs = st.executeQuery("Select * from student order by rollno asc");
ResultSetMetaData rsmd = rs.getMetaData();
// this getColumnCount reurn the number of column in the selected table
int numberOfColumns = rsmd.getColumnCount();
// while loop and with while loop code use for print the data
while (rs.next())
{
for (int i = 1; i <= numberOfColumns; i++)
{
if (i > 1)
System.out.print(", ");
String columnValue = rs.getString(i);
System.out.print(columnValue);
}
System.out.println("");
}
st.close();
con.close();
} catch (Exception ex)
{
System.err.print("Exception: ");
System.err.println(ex.getMessage());
}
}
}
