在navicat中使用mysql的一些命令

1. 创建数据库：CREATE DATABASE db_name;
2. 删除数据库：DROP DATABASE db_name;
3. 创建表：CREATE TABLE table_name (column1 datatype, column2 datatype, column3 datatype, ...);
4. 删除表：DROP TABLE table_name;
5. 插入数据：INSERT INTO table_name (column1, column2, column3, ...) VALUES (value1, value2, value3, ...);
6. 更新数据：UPDATE table_name SET column1 = value1, column2 = value2, ... WHERE condition;
7. 删除数据：DELETE FROM table_name WHERE condition;
8. 查询数据：SELECT column1, column2, ... FROM table_name WHERE condition;
9. 修改表结构：ALTER TABLE table_name ADD COLUMN column_name datatype;
10. 修改表名：RENAME TABLE old_table_name TO new_table_name;
11. 添加索引：CREATE INDEX index_name ON table_name (column_name);
12. 删除索引：DROP INDEX index_name ON table_name.
