Constructor Detail

BatchInserter

public BatchInserter(PreparedStatement ps,
                     Class<?>[] classes,
                     int[] targetSqlTypes)
              throws SQLException

Creates an instance of BatchInserter. The connection which was used to create ps is set to autoCommit=false. This should not be changed while you want to do batch inserts. Calling commitTail resets the autoCommit value.

Parameters:

ps - the PreparedStatement formulating the insertion

classes - an array of classes reflecting the arguments which will be passed to ps; is used for consistency checks

Throws:

SQLException

Method Detail

addData

public void addData(Object... obs)
             throws SQLException

Adds the given data to the batch.

The given objects must correspond to the classes array given in the constructor in length and class types. An IllegalArgumentException will be risen otherwise.

commitTail

public void commitTail()
                throws SQLException

Commits to the database what has been added to the batch but not yet been committed.

Sets the autoCommit value of the connection of the passed PreparedStatement back to what it was when creating the BatchInserter. Thus, the BatchInserter should no longer be used.

Throws:

SQLException
