Interface ExecuteListener

All Superinterfaces:

EventListener, Serializable

All Known Implementing Classes:

CallbackExecuteListener, DefaultExecuteListener, LoggerListener, StopWatchListener

public interface ExecuteListener
extends EventListener, Serializable

An event listener for Query, Routine, or ResultSet render, prepare, bind, execute, fetch steps.

ExecuteListener is a base type for loggers, debuggers, profilers, data collectors that can be hooked into a jOOQ DSLContext using the Configuration.executeListenerProviders() property, passing Settings to DSL.using(java.sql.Connection, SQLDialect, Settings). jOOQ will use that configuration at the beginning of a query execution event to instantiate all the provided listeners. In other words, listeners have the same lifetime as a single query execution, and can thus be used to store state between the moment when a query execution starts, and the moment when a query execution finishes. Advanced ExecuteListeners can also provide custom implementations of Connection, PreparedStatement, ResultSet, SQLException or RuntimeException to jOOQ in appropriate methods.

For convenience, consider extending DefaultExecuteListener instead of implementing this interface. This will prevent compilation errors in future versions of jOOQ, when this interface might get new methods.

The following table explains how every type of statement / operation invokes callback methods in the correct order for all registered ExecuteListeners. Find a legend below the table for the various use cases.

Method Details

prepareStart

  A custom PreparedStatement needs to take into account Settings.getStatementType(), and avoid bind variable markers for StatementType.STATIC_STATEMENT.

  Flags such as Query.queryTimeout(int), Query.poolable(boolean), ResultQuery.maxRows(int), which correspond to mutable flags on a PreparedStatement, are set by jOOQ even if a listener provides the statement.

  Flags such as ResultQuery.resultSetConcurrency(int), ResultQuery.resultSetHoldability(int), ResultQuery.resultSetType(int), which correspond to immutable flags that are set on the statement at statement creation are not set on a statement provided by a listener.

• ExecuteContext.record(): The last Record that was fetched or null if no records were fetched.
• ExecuteContext.result(): The last set of records that were fetched or null if no records were fetched.
• ExecuteContext.sqlWarning(): The SQLWarning that was emitted by the database or null if no warning was emitted.

exception

void exception(ExecuteContext ctx)

Called in the event of an exception at any moment of the execution lifecycle.

Available attributes from ExecuteContext:

• ExecuteContext.connection(): The connection used for execution
• Scope.configuration(): The execution configuration
• ExecuteContext.query(): The Query object, if a jOOQ query is being executed or null otherwise
• ExecuteContext.routine(): The Routine object, if a jOOQ routine is being executed or null otherwise
• ExecuteContext.sql(): The rendered SQL statement that is about to be executed, or null if the SQL statement is unknown..
• ExecuteContext.statement(): The PreparedStatement that is about to be executed, or null if no statement is known to jOOQ. This can be any of the following:
  
  
  • A java.sql.PreparedStatement from your JDBC driver when a jOOQ Query is being executed as StatementType.PREPARED_STATEMENT
  • A java.sql.Statement from your JDBC driver wrapped in a java.sql.PreparedStatement when your jOOQ Query is being executed as StatementType.STATIC_STATEMENT
  • A java.sql.CallableStatement when you are executing a jOOQ Routine
  Note that the Statement may be closed!
• ExecuteContext.resultSet(): The ResultSet that was fetched or null, if no result set was fetched. Note that the ResultSet may already be closed!
• ExecuteContext.rows(): The number of affected rows if applicable.
• ExecuteContext.serverOutput(): The server output if available. This may be fetched when Settings.getFetchServerOutputSize() > 0
• ExecuteContext.record(): The last Record that was fetched or null if no records were fetched.
• ExecuteContext.result(): The last set of records that were fetched or null if no records were fetched.
• ExecuteContext.exception(): The RuntimeException that is about to be thrown
• ExecuteContext.sqlException(): The SQLException that was thrown by the database

warning

void warning(ExecuteContext ctx)

Called in the event of a warning at any moment of the execution lifecycle.

Available attributes from ExecuteContext:

• ExecuteContext.connection(): The connection used for execution
• Scope.configuration(): The execution configuration
• ExecuteContext.query(): The Query object, if a jOOQ query is being executed or null otherwise
• ExecuteContext.routine(): The Routine object, if a jOOQ routine is being executed or null otherwise
• ExecuteContext.sql(): The rendered SQL statement that is about to be executed, or null if the SQL statement is unknown..
• ExecuteContext.statement(): The PreparedStatement that is about to be executed, or null if no statement is known to jOOQ. This can be any of the following:
  
  
  • A java.sql.PreparedStatement from your JDBC driver when a jOOQ Query is being executed as StatementType.PREPARED_STATEMENT
  • A java.sql.Statement from your JDBC driver wrapped in a java.sql.PreparedStatement when your jOOQ Query is being executed as StatementType.STATIC_STATEMENT
  • A java.sql.CallableStatement when you are executing a jOOQ Routine
  Note that the Statement may be closed!
• ExecuteContext.resultSet(): The ResultSet that was fetched or null, if no result set was fetched. Note that the ResultSet may already be closed!
• ExecuteContext.rows(): The number of affected rows if applicable.
• ExecuteContext.serverOutput(): The server output if available. This may be fetched when Settings.getFetchServerOutputSize() > 0
• ExecuteContext.record(): The last Record that was fetched or null if no records were fetched.

• ExecuteContext.exception(): The RuntimeException that is about to be thrown or null, if no exception is being thrown.
• ExecuteContext.sqlException(): The SQLException that was thrown by the database or null, if no exception is being thrown.

This method is only invoked if a warning appears. Note that fetching of warnings can be disabled using Settings.isFetchWarnings()
