限制MySQL REPEAT

Question

我在MySQL中运行以下查询

  REPEAT
    INSERT IGNORE INTO tableB
      SELECT a.column_name, a.level+1
      FROM tableA AS a
  UNTIL Row_Count() = 0 END REPEAT;

但我想对它设置一个限制，以便在a.level超过10（或者是Row_Count（）= 0）时停止重复。我该怎么做？

Answer 1

  REPEAT
    INSERT IGNORE INTO tableB
      SELECT a.column_name, a.level+1
      FROM tableA AS a
      WHERE a.level <= 10
  UNTIL Row_Count() = 0 END REPEAT;

或者我没理解。
