Обсуждение: Autocommit Problem
hello
i am developing an application using tomcat 5.5.6 and postgrsql7.3 (pg73jdbc3.jar) deployed in RedHat linux. Three days earlier updated a column of particular row in a table . When i retrieved the same row from the JSP page it was showing OK.Even when i run the select statement for the row in postgresql console it was showing updated value. But today that means after 3 days when i try to view the row it is showing the old value of row. When i run the select statement for the row in postgresql console it is showing the old value. How can it happen?Can you please help me out. My java code for the updation is shown below.....
String sql = "UPDATE ........";
Connectioncon =DBConnection.getConnection(); // DBConnectio is aclass forgetting theconnection
Statement stmt = con.createStatement();
// Update a row
try {
con.setAutoCommit(false);
int rowsUpdated = stmt.executeUpdate(sql);
if (rowsUpdated != 1) {
System.out.println("Success");
}
con.commit();
}
finally {
stmt.close();
}
with regards

Mridu,
this row doesn't make sense:
if (rowsUpdated != 1) {
I'm sure this should be
if (rowsUpdated == 1) {
Kind regards
