+# 3 测试结论概述
+
+## 3.1 测试整体结论
+
+openGauss兼容MySQL日期处理函数共计执行用例1244条,主要覆盖了特性功能测试。特性功能测试覆盖有效及无效的入参情形、sql_mode严格模式和非严格模式下的执行、插表情形与MySQL执行结果进行比对。累计发现问题3个,已经过Sig专家确认。
+
+1. 日期底层值运算问题(已经过Sig专家确认)
+
+ openGauss日期大于'0000-2-28'时,日期底层值中会包含'0000-2-29',从而如'0000-3-1' - ’0000-2-28‘的日期减法结果比MySQL多一天。
+
+2. 日期小于'0001-01-01 00:00:00'时OpenGauss小数秒正常进位。(已经过Sig专家确认)
+
+3. 函数不支持含零日期(月份或者天数为零)作为入参。(已经过Sig专家确认)
+
+| 测试活动 | 活动评价 |
+| -------- | ------------------------------------------------------------ |
+| 功能测试 | 编译库、编译插件,执行结果符合预期,通过 |
+| 功能测试 | 有效及无效入参测试,通过 |
+| 功能测试 | 特异值输出结果测试,通过 |
+| 功能测试 | 日期类型输入多样性输出结果测试,通过 |
+| 功能测试 | 在常用sql语句、插表测试的输出结果测试,通过 |
+| 功能测试 | 严格模式与非严格模式下对sql语句输出结果测试,通过 |
+
+
+## 3.2 约束说明
+
+1. MySQL使用5.7版本
+
+2. openGauss需使用兼容B库且有dolphin插件
+
+3. openGauss需要用GUC参数dolphin.b_db_timestamp = 0,来控制使用
+ CURDATE(),
+ CURRENT_TIME,
+ CURRENT_TIME(n),
+ CURTIME(),
+ CURRENT_TIMESTAMP,
+ CURRENT_TIMESTAMP(n),
+ CURRENT_TIMESTAMP(),
+ LOCALTIME,
+ LOCALTIME(),
+ LOCALTIME(n),
+ LOCALTIMESTAMP,
+ LOCALTIMESTAMP(),
+ LOCALTIMESTAMP(n),
+ NOW(n)共14个函数。
+
+ 在MySQL侧对应参数名为timestamp。
+
+4. dayname函数和monthname函数受GUC参数dolphin.lc_time_names影响,控制其返回内容所在的语言集。
+
+5. openGauss需要用GUC参数set dolphin.b_compatibility_mode = true,来控制使用last_day(),timestampdiff(),extract()共3个函数。
+
+6. week函数受GUC参数dolphin.default_week_format的影响,改变其mode默认的参数。
+
+7. 在openGauss中设置严格或非严格模式对其输出结果会有所不同

2. 以第一阶段函数用例作为输入测试函数执行结果 | 执行105条用例,输出结果均符合预期。 |
+### 4.1.2 第二阶段函数用例测试
+| 测试步骤 | 测试结果 |
+| ------------------------------------------------------------ | ------------------------------------------------------------ |
+| 1. 在兼容B库并安装dolphin插件的环境
2. 以第二阶段函数用例作为输入测试函数执行结果并插表与MySQL进行对比 | 执行437条用例,发现2个问题
现已进行处理,
1.有42条是小数秒进位在openGauss中是正常进位导致。(已经过Sig专家确认)
2.有18条是因为openGauss中不支持日期中含零导致的。(已经过Sig专家确认)
3.其余函数均符合预期 |
+### 4.1.3 第三阶段函数用例测试
+| 测试步骤 | 测试结果 |
+| ------------------------------------------------------------ | ------------------------------------------------------------ |
+| 1. 在兼容B库并安装dolphin插件的环境
2. 以第三阶段函数用例作为输入测试函数执行结果并插表与MySQL进行对比 | 执行372条用例,发现3个问题
1.addtime中有一条是openGauss自身省略时间末尾0导致,另一条是openGauss中time类型非严格模式时,限定范围为’838:59:59’。在函数参数中,对99991231解析时openGauss非严格模式将其认为是超范围时间,将其限定到’838:59:59’,而后参与运算,mysql则将其视为不合法时间。(已经过Sig专家确认)。
2.convert_tz中有18条是因为openGauss中时区比mysql中要多。(已经过Sig专家确认)
3.timestampdiff中有8条是因为,0年在openGauss中是闰年,在mysql中是平年,导致了运算日期差一天。(已经过Sig专家确认)
4.其余函数均符合预期。 |
