以下是查看MySQL数据库表中的列内容的命令:

``` MySQL [groupName, columnName] = table_name

LOCATION: - ---------------------------------------- | | GROUP BY groupname | | GROUP BY columnName | | GROUP BY cols |-------------------------------------- | | | DATE_SUB(2022-01-01) | | SECOND_SUB(2022-01-01) | | SET COUNT(2) = 2 | | SELECT COUNT(*) FROM table_name | | INTERVAL COUNT(2) FROM table_name | | DELETE COUNT(*, -1) | | INSERT INTO table_name | | INSERT INTO cols | | INSERT INTO good_row(column_name) | | DELETE COUNT(*, -1) ```

其中,GROUP BY groupname参数指定了将查询语句插入到表中的第一个列(即GROUP BY)。

LOCATION 指定了查询的表名。

例如,以下查询语句将查找GROUP BY子句中的列:

``` SELECT table_name, GROUP BY groupname FROM table_name GROUP BY groupname; ```

该语句将查找GROUP BY子句中的列,并返回所有行。
