mysql游标只取到第一个值的解决方案

DECLARE shopItemsCursor CURSOR FOR SELECT id, minItemId, maxItemId, price, amount FROM t_config_mine_shop WHERE appearType = 0; ......FETCH shopItemsCursor INTO configId, minItemId, maxItemId, price, amount;

mysql版本是5.6.21，除了configId之外，其他字段都是null，但是数据库有值，查了下，发现需要给表加别名，并且字段前面带上表的别名，如下

DECLARE shopItemsCursor CURSOR FOR SELECT s.id, s.minItemId, s.maxItemId, s.price, s.amount FROM t_config_mine_shop s WHERE s.appearType = 0; ......FETCH shopItemsCursor INTO configId, minItemId, maxItemId, price, amount;
