SQlite3数据库相关相关命令
SQLite3是一个开源的嵌入式数据库引擎,实现了多数的SQL92标准。以下是一些常用的SQLite3数据库命令:
- 创建数据库:
sqlite3 database_name.db
- 创建表:
CREATE TABLE table_name (column1 datatype, column2 datatype, ...);
- 插入数据:
INSERT INTO table_name (column1, column2, ...) VALUES (value1, value2, ...);
- 查询数据:
SELECT column1, column2, ... FROM table_name WHERE condition;
- 更新数据:
UPDATE table_name SET column1 = value1, column2 = value2, ... WHERE condition;
- 删除数据:
DELETE FROM table_name WHERE condition;
- 创建索引:
CREATE INDEX index_name ON table_name (column1, column2, ...);
- 创建视图:
CREATE VIEW view_name AS SELECT column1, column2, ... FROM table_name WHERE condition;
- 创建触发器:
CREATE TRIGGER trigger_name
BEFORE | AFTER | INSTEAD OF
INSERT | DELETE | UPDATE
ON table_name FOR EACH ROW
BEGIN
-- Trigger logic here
END;
- 创建存储过程:
CREATE PROCEDURE procedure_name (parameter1 datatype, parameter2 datatype, ...)
BEGIN
-- Procedure logic here
END;
请注意,这些命令可以在SQLite3的命令行接口或者在编程语言中(如Python、C#等)使用相应的数据库API执行。
