如何使用 OpenEdge 调试器比较查询文本和缓冲区列表？

Question

I'm working with appBuilder, procedure editor from OpenEdge Progress release 11.6.

Recently I've also started working with the OpenEdge Debugger, also version 11.6.

I have some troubles with the following lines of source code:

txt_Query = "FOR EACH Table1, ...".
...
handle_Query:SET-BUFFERS ("Table1", "Table2", ...).
...
handle_Query:QUERY-PREPARE(txt_Query).

The troubles are expressed by error message 7326, mentioning that the order of the buffers is wrong.

This means that the order of the tables, mentioned in txt_Query and handle_Query:SET-BUFFERS() is different.

I'd like to check the current order, using the debugger, but this is quite a burden, as, when viewing handle_Query in the dataview, I don't see the names of the buffers, but I see something like:

MemberBuffer(1) 1063
MemberBuffer(2) 1064
MemberBuffer(3) 1065
MemberBuffer(4) 1066
MemberBuffer(5) 1067

Does anybody know how to (easily) view this?

Thanks in advance

Answer 1

When you have the query-handle value, right-click an chose Dataview.

Then select MemberBuffer(1) and click on the View button.

Then navigate to the Name property

Answer 2

You should really consider moving to Developer Studio. That would make your life easier.

Right-click the object, select Dataview

Click each MemberBuffer. Click "View"

Select Name and click "Add watch"

Now you have the names in order in view

Demo program for this purpose:

DISPLAY "running".

DEFINE TEMP-TABLE tt NO-UNDO 
FIELD a AS INTEGER .

DEFINE TEMP-TABLE tt2 NO-UNDO 
FIELD a AS INTEGER.

DEFINE VARIABLE hQuery AS HANDLE NO-UNDO.

CREATE QUERY hQuery.

hQuery:SET-BUFFERS(BUFFER tt:HANDLE , BUFFER tt2:HANDLE).

READKEY.

// Error here...
hQuery:QUERY-PREPARE("for each tt2, each tt") .
