This might be a weird query but its related to deleting specific details in database.
Bascially I had built a database using a set of files
and after building the database i realized that i didn't need the whole data. i am required to not only delete content of database related to seq2 to seq4 but also delete content related to last 200 bytes in seq1
Basically i am required to retain only first 100 mb of data in seq1.
without going through the whole procedure of rebuilding the db could i delete contents of database corresponding to these requirements.
i know its a little unusal but could some one give a direction.

Creating a SQLite database
GRASS is automatically creating the SQLite database if it is not yet existing when the first table is created in the SQLite database. It is
sufficient to define the connection (see next step).
Connecting GRASS to SQLite
The database name 'sqlite.db' is at user's choice. Also the file storage location can be freely chosen. If the database does not exist, it
will be automatically created when database content is created:
# example for storing DB in mapset directory (keep single quotes):
db.connect driver=sqlite database='$GISDBASE/$LOCATION_NAME/$MAPSET/sqlite.db'
db.connect -p
Supported SQL commands
All SQL commands supported by SQLite (for limitations, see SQLite help page: SQL As Understood By SQLite and Unsupported SQL).
Operators available in conditions
All SQL operators supported by SQLite.
Browsing table data in DB
A convenient SQLite front-end is sqlitebrowser. To open a DB file stored within the current mapset, the following way is suggested (corre-
sponds to above database connection):
eval `g.gisenv`
# use double quotes:
sqlitebrowser "$GISDBASE/$LOCATION_NAME/$MAPSET"/sqlite.db
