navicat使用sql语句

1. 创建表格：

CREATE TABLE table_name (
column1 datatype,
column2 datatype,
column3 datatype,
....
);

2. 插入数据：

INSERT INTO table_name (column1, column2, column3, ...)
VALUES (value1, value2, value3, ...);

3. 修改数据：

UPDATE table_name
SET column1 = value1, column2 = value2, ...
WHERE condition;

4. 删除数据：

DELETE FROM table_name
WHERE condition;

5. 查询数据：

SELECT column1, column2, ...
FROM table_name
WHERE condition;

6. 排序数据：

SELECT column1, column2, ...
FROM table_name
ORDER BY column1 DESC, column2 ASC;

7. 分组数据：

SELECT column1, COUNT(column2)
FROM table_name
GROUP BY column1;

8. 连接数据：

SELECT column1, column2, ...
FROM table_name1
INNER JOIN table_name2 ON condition;

9. 子查询：

SELECT column1, column2, ...
FROM table_name
WHERE column1 IN (SELECT column1 FROM table_name WHERE condition);
