All Database variables begin with $d_ and each variable has a given type. Caches database variables are displayed as columns and more information can be found here. ("string" database variables have a physical limit of 2gb)
Most database variables can be updated simply by using the statement $d_SomeVariable = $SomeValue, where $d_SomeVariable is a valid database variable and $SomeValue is any valid variable or literal (but it must match the data type of the database variable). This actually updates your database, but as some variables are calculated from other items in the database there are exceptions. These are: $d_Bearing, $d_Changed, $d_Degrees, $d_Distance, $d_FoundCount, $d_HasCorrected, $d_HasUserNote, $d_HastravelBug, $d_LastFoundDate, $d_LastGPXDate, $d_LastLog, $d_LastUserDate, $d_LatOriginal, $d_LonOriginal, $d_NumberOfLogs, $d_UserNoteDate, $d_cByUser, $d_cParent, $d_cPrefix, $d_kBeforeCounty, $d_kBeforeState, $d_kCode, $d_kBeforeLat, $d_kBeforeLon, $d_lIsowner, $d_lParent, $d_aName
$d_ Database variables are separated into 5 GSAK tables - caches, corrected, logs, waypoints, and attributes You can navigate through each of these tables using the Table and Goto commands. Note: The tables CacheImages, LogImages and Custom are not supported in this manner - use Sqlite to read these tables.

Notes:
User created ($d_cByUser = True) child waypoints are effectively locked from updates by Geocaching.com additional waypoints that have the same code
$d_cPrefix is provided for version 6 compatibility and is read only because it is set via $d_cCode. That is, $d_cPrefix is always equal to the first 2 characters of $d_cCode
The current possible values for $d_cType are set by GroundSpeak and they include:
Final Location
Parking Area
Question to Answer
Stages of a Multicache
Trailhead
Reference Point
You can also add your own types (more information)
By setting the $d_cFlag in a macro you can control which child waypoints will be selected for export. Most export dialogs have the following option:

| $d_aId | Numeric | Attribute ID number |
| $d_aName | String | Attribute name/description |
| $d_aInc | Boolean | 1=Include, 0 = exclude |
Note: currently the attributes table is read only. It is provided here for consistency with other tables, but it is recommend that you use sqlite() in macros to read and interrogate attribute data.
