限制MySQL的REPEAT

Question

我运行下面的查询在MySQL

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

，但我想提出一个限制它，使它停止重复，如果a.level得到上述10（或ROW_COUNT（）= 0 ）。我将如何做到这一点？

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; 

或者我不明白。
