This article introduces the relevant knowledge of "what is the method of ibatis dealing with batch update". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

Recently, we have encountered the problem of requiring bulk update data. At first, we used a for loop to update, which is very inefficient when the amount of data is large. The reason is that every time a for loop update a statement, it is a join process. When there are a large number of data updates, the efficiency can be imagined.

The code is as follows:

Final List tempList = list

Try {

If (List tempList! = null) {

Template.execute (

New SqlMapClientCallback () {

Public Object doInSqlMapClient (SqlMapExecutor executor) throws

SQLException {

Executor.startBatch ()

For (int I = 0, n = tempList.size (); I < n; iTunes +) {

Executor.update ("test.batchupdate", (Map) tempList.get (I))

}

Executor.executeBatch ()

Return null

}

}

);

}

}
