JDBC Driver for Oracle Service Cloud

Build 23.0.8839

Batch Processing

The CData JDBC Driver for Oracle Service Cloud enables you to take advantage of the bulk load support in Oracle Service Cloud through the JDBC batch API. You can use the batch API to execute related SQL data manipulation statements simultaneously.

Using the JDBC Batch API

The following examples show how to execute bulk operations with the PreparedStatement class.

Bulk Delete

To perform a bulk delete with a PreparedStatement, call addBatch for each set of parameters you want to execute as part of the bulk delete. After adding all the sets of parameters to the batch, call executeBatch.

The executeBatch method returns the update counts for each statement in an array. For example:

String query = "DELETE FROM Accounts WHERE Id = ?";
PreparedStatement pstmt = conn.prepareStatement(query);



int[] r = pstmt.executeBatch();
for(int i: r)

Setting the Batch Size

Setting the maximum batch size can be necessary when the server has limitations on the size of the request that can be submitted. Set the BatchSize property to split the entire batch into batches of the specified value. Each batch is submitted to the server individually.

Or, set BatchSize to 0 to submit the entire batch.
