InterSystems 常见问题系列
使用 ErrorList 查询 SYS.ApplicationError 类.
- 注 1: 在 %SYS 命名空间中运行.
- 注 2: 这是个非存储的utility, 所以我们用 %ResultSet 类而不用 %SQL.Statement.
执行命令的例子如下.
USER>set $namespace="%SYS"
%SYS>set rset=##class(%ResultSet).%New()
%SYS>set rset.ClassName="SYS.ApplicationError"
%SYS>set rset.QueryName="ErrorList"
%SYS>do rset.Execute("USER","08/17/2020")
%SYS>do rset.%Display()
Error # Error message Time Process DisplayPID Username Code line
1 <DIVIDE> 02:43:10 2536 2536 irisowner
1 Rows(s) Affected
%SYS>do rset.Close()
以下显示如何获得在浏览行时获取SELECT的列值The following shows how to get column values of a SELECT while navigating through rows.
使用Next()方法来移动到一行（如果行存在的话返回1）
获取一列的话使用 Get("column name"). 具体列名，请参考类文档里面的ErrorList 查询描述。
关于ErrorList 查询的列名.
%SYS>do rset.Execute("USER","08/17/2020")
%SYS>while rset.Next() { write rset.Get("Error #"),"-",rset.Get("Error message"),"-",rset.Get("Time"),"-",rset.Get("Code line"),!}

For terminal viewing, you can also use the ^%ER routine.
Execute the following while in the namespace you want to reference (the example is executed in the USER namespace).
The green bold underlined text indicates the input area.
USER>do ^%ER
