Database Variables

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.

[1] - The user note is comprised of two sections, the note section and the log section (see notes dialog) These two sections are separated by the literal string "$~ ". If you wish to split the user notes into these two discrete sections then the macro code would go something like:
$NoteSection = Extract($d_UserNote,"$~",1) 
$LogSection = Extract($d_UserNote,"$~",2)

For a more complete explanation of some of these fields please this topic

$d_Status (Cache Status):

A = Available

Variable Type Description
$d_kCode String  Parent waypoint code
$d_kBeforeLat String  Latitude before correction (from load of last GPX file)
$d_kBeforeLon String  Longitude before correction (from load of last GPX file)
$d_kBeforeState String State before correction (from load of last GPX file)

kType - possible values, api - when a corrected coordinate is added/changed via the api. gui - when a corrected coordinate is added/change via the GSAK GUI. macro - when using the macro command "Addnew" .

Note: GSAK automatically keeps the fields $d_kBeforeLat and $d_kBeforeLon in sync with the caches table $d_LatOriginal and $d_LonOriginal. Consider these corresponding fields ans "synonymous" if you will.

Variable Type Description
$d_lParent  String  Parent waypoint code
$d_lType  String  Log type
$d_lText String  Full log text
$d_lBy  String  Logged by name
$d_lDate Date Date of log

Variable Type Description
$d_cParent  String  Parent waypoint code
$d_cCode  String  Child waypoint code
$d_cPrefix String  Child prefix (same as first 2 characters of code)
$d_cName String  Child waypoint name
$d_cType String  Child waypoint type (see notes)
$d_cLat String  Child waypoint latitude (decimal degrees - string)
$d_cLon  String  Child waypoint longitude (decimal degrees - string)
$d_cUrl  String  Child waypoint URL
$d_cComment  String  Child comment
$d_cByUser  Boolean  Child waypoint created by user (not
$d_cDate  Date  CDate the child waypoint was created
$d_cFlag Boolean  Child user flag

User created ($d_cByUser = True) child waypoints are effectively locked from updates by 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
Reference Point
Physical Stage
Virtual Stage

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:

Attributes (use view "attname" to also include $d_aName) 
Variable Type Description
$d_aCode  String  Cache waypoint code
$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.
