The builder create method. Given the function name and list or arguments, this method creates an Item that represents the function call. In case or errors, a NULL item is returned, and an error is reported. Note that the thd object may be modified by the builder. In particular, the following members/methods can be set/called, depending on the function called and the function possible side effects.

  • thd->lex->binlog_row_based_if_mixed
  • thd->lex->current_context()
  • thd->lex->safe_to_cache_query
  • thd->lex->uncacheable(UNCACHEABLE_SIDEEFFECT)
