                                                                                                               org.mule.runtime.extension.api.runtime.operation.FlowListener flowListener)
                                                                                                        throws SQLException

Selects data from a database. Streaming is automatically applied to avoid preemptive consumption of such results, which may lead to performance and memory issues.

Parameters:

query - a QueryDefinition as a parameter group

connector - the acting connector

Returns:

depending on the value of streaming, it can be a List or Iterator of maps

Throws:

SQLException - if an error is produced

querySingle

public Map<String,Object> querySingle(QueryDefinition query,
                                      AbstractDbConnector connector,
                                      DbConnection connection,
                                      org.mule.runtime.extension.api.runtime.streaming.StreamingHelper streamingHelper)
                               throws SQLException

Selects single result from a database. If the indicated SQL query returns more than one record, only the first one is returned. Streaming is not used for this operation, which means that you must be careful because all selected fields will be loaded to memory.

Parameters:

query - a QueryDefinition as a parameter group

connector - the acting connector

connection - the acting connection

Returns:

a map with a single entry containing the operation's output

Throws:

SQLException - if an error is produced

Since:

1.9.0

                              DbConnection connection,
                              org.mule.runtime.extension.api.runtime.streaming.StreamingHelper streamingHelper)
                       throws SQLException

Updates data in a database.

Parameters:

           throws SQLException

Deletes data in a database.

Parameters:

query - QueryDefinition as a parameter group

connector - the acting connector

connection - the acting connection

Returns:

storedProcedure

public Map<String,Object> storedProcedure(StoredProcedureCall call,
                                          AutoGenerateKeysAttributes autoGenerateKeysAttributes,
                                          AbstractDbConnector connector,
                                          DbConnection connection,

                                   throws SQLException

Invokes a Stored Procedure on the database.

When the stored procedure returns one or more ResultSet instances, streaming is automatically applied to avoid preemptive consumption of such results, which may lead to performance and memory issues.

connection - the acting connection

Returns:

A Map with the procedure's output

Throws:

SQLException - if an error is produced
