1. Open the axf in ArcPad Studio.
2. In the tree under "Feature Layers" right-click on the feature class.
3. Select "Show Data"
You will be able to see the AXF_STATUS field on the right-hand side of the list of fields.
4. To modify the current value, remove the SQL statement that's in the top box already and replace it with the following:
UPDATE TABLENAME
SET AXF_STATUS='1'
WHERE AXF_OBJECTID >= 2
The "TABLENAME" is the name of your feature class, but in all upper-case letters.
The WHERE clause can be utilized to only change a portion of your data. If you wanted to change the value for every row in the feature class, just utilize the first two lines.
3. After you have the modified SQL statement, click the red exclamation mark button on the main toolbar to run the statement.
The following messages should be returned if you have written a valid SQL statement:
Command completed with # rows affected.
Command completed successfully.
After this you should be able to close the command window, right-click the feature class again, and select "Show data". You will now see that the value has changed for the records you specified. You can then check this data back into ArcMap.
Hope this helps.
