bulkInsert

public int[] bulkInsert(List<Map<String,Object>> bulkInputParameters,
                        BulkQueryDefinition query,
                        AbstractDbConnector connector,
                        DbConnection connection,
                        org.mule.runtime.extension.api.runtime.streaming.StreamingHelper streamingHelper)
                 throws SQLException

Allows executing one insert statement various times using different parameter bindings. This happens using one single Database statement, which has performance advantages compared to executing one single update operation various times.

Parameters:

query - a BulkQueryDefinition as a parameter group

bulkInputParameters - A List of Maps in which every list item represents a row to be inserted, and the map contains the parameter names as keys and the value the parameter is bound to.

connector - the acting connector

connection - the acting connection

Returns:

an array of update counts containing one element for each executed command. The elements of the array are ordered according to the order in which commands were added to the batch.

Throws:

SQLException - if an error is produced

bulkUpdate

public int[] bulkUpdate(List<Map<String,Object>> bulkInputParameters,
                        BulkQueryDefinition query,
                        AbstractDbConnector connector,
                        DbConnection connection,
                        org.mule.runtime.extension.api.runtime.streaming.StreamingHelper streamingHelper)
                 throws SQLException

Allows executing one update statement various times using different parameter bindings. This happens using one single Database statement, which has performance advantages compared to executing one single update operation various times.

Parameters:

query - a BulkQueryDefinition as a parameter group

bulkInputParameters - A List of Maps in which every list item represents a row to be inserted, and the map contains the parameter names as keys and the value the parameter is bound to.

connector - the acting connector

connection - the acting connection

Returns:

an array of update counts containing one element for each executed command. The elements of the array are ordered according to the order in which commands were added to the batch.

Throws:

SQLException - if an error is produced

bulkDelete

public int[] bulkDelete(List<Map<String,Object>> bulkInputParameters,
                        BulkQueryDefinition query,
                        AbstractDbConnector connector,
                        DbConnection connection,
                        org.mule.runtime.extension.api.runtime.streaming.StreamingHelper streamingHelper)
                 throws SQLException

Allows executing one delete statement various times using different parameter bindings. This happens using one single Database statement, which has performance advantages compared to executing one single delete operation various times.

Parameters:

query - a BulkQueryDefinition as a parameter group

bulkInputParameters - A List of Maps in which every list item represents a row to be inserted, and the map contains the parameter names as keys and the value the parameter is bound to.

connector - the acting connector

connection - the acting connection

Returns:

an array of update counts containing one element for each executed command. The elements of the array are ordered according to the order in which commands were added to the batch.

Throws:

SQLException - if an error is produced

executeScript

public int[] executeScript(BulkScript script,
                           QuerySettings settings,
                           DbConnection connection)
                    throws SQLException

Parameters:

script - a BulkScript as a parameter group

settings - a QuerySettings as a parameter group

connection - the acting connection

Returns:

an array of update counts containing one element for each executed command. The elements of the array are ordered according to the order in which commands were added to the batch.

Throws:

SQLException - if an error is produced

resolveQuery

protected Query resolveQuery(BulkQueryDefinition query,
                             AbstractDbConnector connector,
                             DbConnection connection,
