Interface JdbcSelect

All Superinterfaces:
CacheableJdbcOperation, JdbcOperation, PrimaryOperation
@Incubating(since="6.0", group="sql-execution") @SPI({USE,SUPPLY}) public interface JdbcSelect extends PrimaryOperation, CacheableJdbcOperation

Primary selection operation performed through JDBC.

Create this operation with JdbcOperations.select(SqlAstTranslationRequest.Select) when implementing a custom SQL AST translator. Do not implement this interface directly.

      JdbcLockingApplication getLockingApplication()

      Which stage owns pessimistic locking for this execution plan.

      Consumers must honor this disposition instead of inferring locking from the SQL string.

    • performPreActions

      void performPreActions(StatementAccess jdbcStatementAccess, Connection jdbcConnection, ExecutionContext executionContext)
      Perform any pre-actions.

      Generally the pre-actions should use the passed jdbcStatementAccess to interact with the database, although the jdbcConnection can be used to create specialized statements, access the database metadata, etc.

      Parameters:
      jdbcStatementAccess - Access to a JDBC Statement object which may be used to perform the action.
      jdbcConnection - The JDBC Connection.
      executionContext - Access to contextual information useful while executing.

    • performPostActions

      void performPostActions(boolean succeeded, StatementAccess jdbcStatementAccess, Connection jdbcConnection, ExecutionContext executionContext, LoadedValuesCollector loadedValuesCollector)
      Perform any post-actions.

      Generally the post-actions should use the passed jdbcStatementAccess to interact with the database, although the jdbcConnection can be used to create specialized statements, access the database metadata, etc.

      Parameters:
      succeeded - Whether the primary operation succeeded.
      jdbcStatementAccess - Access to a JDBC Statement object which may be used to perform the action.
      jdbcConnection - The JDBC Connection.
      executionContext - Access to contextual information useful while executing.
      loadedValuesCollector - Access to the collector of values loaded as part of the primary operation. This is useful for post-actions that need to know what was loaded in order to perform their work.
