SQL区分大小写.我使用过的MySQL和SQL Server似乎都是敏感的.总是这样吗?标准是否定义了区分大小写?
我是Postgresql的新手,我正在尝试从MySQL迁移我的应用程序.
我有一个具有以下结构的表:
Table "public.tbl_point"
Column | Type | Modifiers | Storage | Description
------------------------+-----------------------+-----------+----------+-------------
Tag_Id | integer | not null | plain |
Tag_Name | character varying(30) | not null | extended |
Quality | integer | not null | plain |
Execute | integer | not null | plain |
Output_Index | integer | not null | plain |
Last_Update | abstime | | plain |
Indexes:
"tbl_point_pkey" PRIMARY KEY, btree ("Tag_Id")
Triggers:
add_current_date_to_tbl_point BEFORE UPDATE ON tbl_point FOR …Run Code Online (Sandbox Code Playgroud)
