dbsql [OPTIONS] FILENAME SQL
dbsql is a command line tool that provides access to the Berkeley DB
SQL interface.
To build this tool, run the configure script with the
--enable-sql option when you are building the
Berkeley DB SQL interface. For more information on building this tool,
see
"Building for UNIX/POSIX".
FILENAME is the name of a Berkeley DB database file created with the SQL interface. A new database is created if the file does not exist. The options are as follows:
-init filename
Reads/processes named file.
-echo
Prints commands before execution.
-[no]header
Turns headers on or off.
-bail
Stops after hitting an error.
-interactive
Forces interactive I/O.
-batch
Forces batch I/O.
-column
Sets output mode to column.
-csv
Sets output mode to csv.
-html
Sets output mode to HTML.
-line
Sets output mode to line.
-list
Sets output mode to list.
-separator 'x'
Sets output field separator (|).
-nullvalue 'text'
Sets text string for NULL values.
-version
Shows SQLite version.
The dbsql executable provides the same interface as the sqlite3
executable that is part of SQLite. For more information on how
to use dbsql see the
SQLite Documentation page.
This section describes pre-defined query statements that can be
executed from the dbsql command line. These queries take the form
of:
.stat ITEM
where ITEM is an optional parameter that indicates
what statistics to print. If ITEM is not
specified, then this command prints statistics for the Berkeley DB
environment, followed by statistics for all tables and indexes
within the database.
If ITEM is the name of a table or index, then this
command prints statistics for the table or index using the
DB->stat_print()
method.
Otherwise, ITEM can be one of several keywords.
They are:
:env:
dbsql> .stat :env:
Causes this command to print statistics for the Berkeley DB environment using the DB_ENV->stat_print(). method.
:rep:
dbsql> .stat :rep:
Causes this command to print a summary of replication statistics.
