Member Function Documentation

◆ eligible_secondary_storage_engine()

const MYSQL_LEX_CSTRING * Sql_cmd_insert_select::eligible_secondary_storage_engine ( ) const

overridevirtual

Is this statement of a type and on a form that makes it eligible for execution in a secondary storage engine?

Returns: the name of the secondary storage engine, or nullptr if the statement is not eligible for execution in a secondary storage engine

Reimplemented from Sql_cmd.

◆ sql_command_code()

enum_sql_command Sql_cmd_insert_select::sql_command_code ( ) const

inlineoverridevirtual

Return the command code for this statement.

Implements Sql_cmd.
