InterSystems FAQ rubric

Use the ErrorList query of the SYS.ApplicationError class.

• Note 1: Runs in the %SYS namespace.
• Note 2: This is a non-stored utility, so we use the %ResultSet class rather than %SQL.Statement.

An example of command execution is as follows.

USER>set $namespace="%SYS"   //equal to zn "%SYS"

%SYS>set rset=##class(%ResultSet).%New()

%SYS>set rset.ClassName="SYS.ApplicationError"

%SYS>set rset.QueryName="ErrorList"

// The first argument of the query is the namespace name, the second argument is the date (in MM/DD/YYYY format).
%SYS>do rset.Execute("USER","08/17/2020")

// To display the results on the screen, execute the %Display() method.
%SYS>do rset.%Display()
Error # Error message   Time    Process DisplayPID      Username        Code line

1 Rows(s) Affected

%SYS>do rset.Close()

The following shows how to get column values ​​of a SELECT while navigating through rows.

To move to a row, use the Next() method (which returns 1 if the row exists).

To get a column, use Get("column name"). For details on column names, please refer to the description of the ErrorList query in the class documentation.

About column names of ErrorList queries.

%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
