Constructor Detail

MQLRelationalDataComponent

public MQLRelationalDataComponent()

Method Detail

getMqlQuery

public MQLQuery getMqlQuery()

getLogger

public Log getLogger()

Overrides:

getLogger in class SQLLookupRule

validateAction

public boolean validateAction()

Description copied from class: SQLBaseComponent

validates the action. checks to verify inputs are available to execute - verify query is available - verify connection is available, via jndi, connection string, or prepared component - verify output is specified

Overrides:

validateAction in class SQLBaseComponent

getQuery

public String getQuery()

makes the necessary calls to generate the SQL query based on the MQL XML provided.

Overrides:

getQuery in class SQLBaseComponent

Returns:

sql

executeAction

public boolean executeAction()

Description copied from class: SQLBaseComponent

determines state of component, and executes accordingly. various inputs that impact the state include: live - returns a live result set vs. an in memory copy transform - transform a result set based on additional inputs prepared_component - if available, use existing connection from prepared component max_rows - sets the number of rows that should be returned in result sets The specified output also impacts the state of the execution. If prepared_component is defined as an output, setup the query but delay execution.
