我不是 SQL 程序员,但我在项目中遇到了障碍,必须构造一个触发器,该触发器将在插入命令后触发。问题如下:
我有 3 张桌子:
dbo. Build
id (PK, int, not null)
date (smalldatetime, not null)
dbo.TestCase
id (PK, int, not null)
Name (nvarchar(200), not null)
dbo.TestCaseExecution
id (PK, int, not null)
build_id (FK, int, not null)
testcase_id (FK, int, not null)
passed (int, null) //1 or 0
executed (int, null) //1 or 0
duration (real, null)
fail_percentage (real, null) //null
现在,我从 .xml 文件中读取数据,并通过用 C# 编写的项目将数据添加到数据库中。每次构建后,我必须根据“通过”和“执行”值更新数据库并计算每个测试的 fail_percentage。
fail_percentage = (100)*(1 - (PassNumber/ExecutionNumber))
所以我需要一个触发器,它将: 1. 在插入命令后触发 2. 根据早期值计算 fail_percentage,例如
after reading from file:
id build_id testcase_id passed executed duration fail_percentage
1 1 001 1 1 12:09 null
after trigger:
id build_id testcase_id passed executed duration fail_percentage
1 1 001 1 1 12:09 0
after reading from file:
id build_id testcase_id passed executed duration fail_percentage
1 1 001 1 1 12:09 0
2 2 001 0 1 12:32 null
after trigger:
id build_id testcase_id passed executed duration fail_percentage
1 1 001 1 1 12:09 0
2 2 001 0 1 12:32 50
谁能帮帮我?
在此先感谢,阿图尔
