B: True. Multiple table insert statements, specifically the conditional INSERT ALL, can transform a single row from the source table into multiple rows in one or more target tables depending on the conditions specified in the WHEN clauses.
E: True. The unconditional INSERT ALL statement will insert rows into multiple target tables without any conditions. However, it does not require the same number of columns in both the source and target tables. The INSERT ALL syntax allows you to specify different columns for each target table into which rows will be inserted.
Multiple table insert operations allow for complex insert scenarios, where based on the data, one can insert into different tables or multiple times into the same table based on different conditions.
References:Oracle SQL reference details the use of INSERT ALL and INSERT FIRST clauses for inserting into multiple tables based on conditions specified.
