可用于帮助开发人员比较两个数据库之间的差异(表,列,约束,事件,函数,存储过程,触发器,视图),并生成更新语句。 Can be used to synchronize database structures, compare differences(table,column,constraints,events,functions,procedures,triggers,views) between databases and generating queries.
- Handle Create Tables
- Handle Alter Tables
- Handle Drop table Queries
- Handle constraints (PK,FK,index, ... etc)
- Handle events
- Handle functions
- Handle procedures
- Handle triggers
- Handle views
to install this library using composer:
composer require 9raxdev/mysql-struct-sync
1.无法识别rename字段,更改数据库字段名称在代码中的体现为:先删除命名前的字段,再增加命名后的字段。The rename field is not recognized. Changing the database field name in the code is as follows: first delete the field before the name, and then add the named field.
2.advanceDiff()必须基于baseDiff()前提下,因为储存过程,触发器,函数等特性都依赖数据表。advanceDiff() must be based on baseDiff(), because procedures, triggers, functions, etc. depend on the tables.
