suppose, i have 1000 transactions say inserts, updates, deletes to be executed. I have to execute these in order. that is i can not break the order. I have to perform these tansactions on the database using executeBatch and using PreparedStatement. I am able to execute these transactions using Statement objects but i need to make use of bind variables. Is there some way i can do this. please help.
You could wite SQL which defines an anonomous predure I suppose, but it would be awkward. Also you could write a Stored Procedure which does this, and execute that via a CallableStatement. But again, I'd have to ask why you would want to do this in the first place?
i have a very large(>10000) number of transactions to execute. hence i want to use batchExecute(). my large number of transactions are a collection of insert,update and delete transactions. I have to follow the order of transaction and hence i cannot use three seperate batches. I have to use preparedStatement for the reason that i can use bind variables and hence it is very efficient. So I would like to know a work around for the above situation.
Your explanation makes more sense now ramu av. I asked why because your example has you creating, updateing then deleting the same record, which seemed like an odd thing to do.
Statements addBatch method adds another distinct SQL statement to a batch of SQL statements. If you use PreparedStatements, you only have three distinct pieces of SQL which are compiled and reused, so you don't need to create a batch. You shouldn't however be trying to do this in one PreparedStatement. All you need do is loop through your 10000+ collection of objects to create,update and delete and bind their parameters accordingly.
