sqltransaction

Need help in JDBC transaction control mechanism in JAVA. Issue: There are certain stored procedures in our Sybase DB that needs to be run on Unchained mode. Since we are updating our data on two different databases (unfortunately, both Sybase) we need to be able to rollback all our previous transactions, if there is any failure. But running with Unchained Mode (Auto commit - on) is not helping us with the rollbacks as some of the SPs have already committed the transactions. Connection connection = getConnection(); PreparedStatement ps = null; try{ String sql = getQuery(); // SQL Chained Mode

How Can I check if a dotnet transaction is closed or not ? using(TransactionScope scope = new TransactionScope(TransactionScopeOption.RequiresNew)){ try{ //Do something; scope.Complete(); //denotes the transaction completed successful. } catch(TransactionAbortedException ex) { //scope.Complete(); is never called, the transaction rolls back automatically. } catch(ApplicationException ex) { } } Your title asks one thing and your question asks another. so, I am going with your title. If you want to know if the transaction is rolled back or set to rollback only, you can check transaction

I have a scenario in which I have to process multiple .sQL files, every file contains 3-4 insert or Update queries, now when any query in a file fails I do rollback whole transaction means whole file we be rolled back , and all other files executed before that file will get committed, I want an option where user can rollback entire transaction means all queries in a file executed and all files executed before that particular file containing error, and if user wants to skip that particular file with error we will just rollback single file which contains error all other files will get committed,

I have a loop where I call stored procedure with different parameter value. Next call cmd.ExecuteNonQuery(); I use transaction to save all or rollback, and checkBox2 - save always. I found one problem and I can't find solution. After first problem when catch block is fired transaction object loses its connection. t.connection is null! Everything is good but transaction object is without connection at start it has! try { while (!sr.EndOfStream) { strLine.Remove(0, strLine.Length); //c = sr.ReadLine(); while (c != "-") { c = sr.ReadLine(); strLine.Append(c ); if (sr.EndOfStream) break; } /

Do I need to call dispose in the finally block for SqlTransaction? Pretend the developer didnt use USING anywhere, and just try/catch. SqlTransaction sqlTrans = con.BeginTransaction(); try { //Do Work sqlTrans.Commit() } catch (Exception ex) { sqlTrans.Rollback(); } finally { sqlTrans.Dispose(); con.Dispose(); } Tim Schmelter Do I need to use try-finally or the using -statement to dispose the SqlTransaction ? It does not hurt to have it. This is true for every class implementing IDisposable , otherwise it would not implement this interface. But normally the garbage collector would deal with it
