MySQL database driver in GRASS enables GRASS to store vector attributes in MySQL server. Because vector attribute tables are created automaticaly when a new vector is written and the name of the table is the same as the name of the vector it is good practice to create a new database for each GRASS mapset….
MySQL database driver in GRASS enables GRASS to store vector attributes in MySQL embedded database without necessity to run MySQL server. Driver and database name GRASS modules require 2 parameters to connect to a database. Those parameters are ‘driver’ and ‘database’. For MySQL embedded driver the parameter ‘driver’ should be set to value ‘mesql’. The…
Defining the DBF driver The DBF driver is the default driver, in theory no user interaction is required. However, if the settings should be set back from a different to the DBF driver, the following step is required: # keep single quotes: db.connect driver=dbf database=’$GISDBASE/$LOCATION_NAME/$MAPSET/dbf/’ db.connect -p The dbf/ subdirectory in the mapset must exist…
