sql - DB2 の from 節に update または create ステートメントを入れることはできますか?

Question

DB2 の from 句で DML を使用できますか? ありがとうございました

Answer 1

The DB2 V9 SQL Reference states that the FROM clause can only contain a table-reference:

     .-,---------------.   
     V                 |   
>>-FROM----table-reference-+-----------------------------------><

The description of "table-reference" is directly below that, so it will tell you exactly what is allowed and what is not allowed. A table-reference can include "Data change table references," one of which is "NEW TABLE." Maybe that's what you're after, but as other people have already said, without knowing what you're trying to do, it's hard to answer the question.

どうしてそうするか？SQLステートメントでそれを見たことはないと思います...
