查看数据库类型和版本的命令是Microsoft Access的命令行选项。以下是一些常见的SQL查询和版本选项:

1. "sql-mode"命令:此命令将使用Microsoft Access的SQL语言。该选项允许您在查询结果中使用多个列,以及在多个表中查看数据。

2. "sql-diff"命令:这个选项允许您指定一个表的查询结果。例如,如果您想查看主键列,则可以使用以下SQL语句: SELECT * FROM users WHERE id IN (SELECT id, COUNT(*) AS Total_amount) AND date IN (SELECT duration, INTERVAL TIMESTAMP);

3. "sql-grouped_rows"命令:此选项允许您指定多个列,以及每个列的字段数。例如,如果您想查看包含多个字段的表中的所有记录,则可以使用以下SQL语句: SELECT * FROM users WHERE ids IN (SELECT id, COUNT(*) AS total_count) AND name IN (SELECT title, COUNT(*) AS total_title) AND age IN (SELECT date, INTERVAL TIMESTAMP) FROM users ORDER BY ids DESC AS total_count AND title AS total_title AND age AS total_age FROM users ORDER BY title DESC AS total_title AND name DESC AS name ORDER BY age DESC AS total_name

4. "sql-grouped_rows"命令:此选项允许您指定多列的查询结果。例如,如果您想查看表中的所有记录,则可以使用以下SQL语句: SELECT * FROM users WHERE ids IN (SELECT id, COUNT(*) AS total_count) AND name IN (SELECT title, COUNT(*) AS total_title) AND age IN (SELECT date, INTERVAL TIMESTAMP) AND id FROM users ORDER BY ids DESC

这些选项使用不同的SQL语言,因此您可以单独使用或组合使用。
