Try running SQLite from a command line and tell it to import the file itself instead of going through SQLite Browser. Many SQLite tools have shown issues mangling text into our out of SQLite, including command line shells. If you're using anything other than the C-level API's, then you should never care about encoding-the API's used by the tool you're using will dictate what encoding should be used. Even if SQLite is using a different encoding depending, the only end result is that it will cause some extra computation as SQLite converts from stored encoding to API-requested encoding constantly. However, if you have a problem with garbled text it's pretty much always a problem with one of the tools being used, not SQLite itself. If you have a database and need a different encoding, then you need to create a new database with the new encoding, and then recreate the schema and import all the data. To create a new database with a specific encoding, open a SQLite connection to a blank file, run this pragma: PRAGMA encoding = 'UTF-8' You cannot change the encoding for an existing database.

This manual page was originally written by Andreas Rottmann, for the Debian GNU/Linux system (but may be used by others).You can test the encoding with this pragma: PRAGMA encoding O All other command line options are processed. O If the -init option is present, the specified file is processed. can be found in the user's home directory, it is read and processed. > 'o If the file ~/.sqliterc exists, it is processed first. O The default configuration is established as follows:Ĭontinue prompt = '. The sequence of initialization is as follows: Throughout initialization, any previously specified Sqlite3 reads an initialization file to set the configuration of the interactive environment. nullvalue string Set string used to represent NULL values. separator separator Set output field separator. Query results will be displayed with the separator (|, by default) character between each field value. Designed to be easily parsed by scripts or other programs Query results will be displayed with one value per line, rows separated by a blank line.

Query results will be output as simple HTML tables. column Query results will be displayed in a table like form, using whitespace characters to separate the columns and align the output. init file Read and execute commands from file, which can contain a mix of SQL statements and meta-commands. timeout MS Try opening locked tables for MS milliseconds tables ?PATTERN?

What is SQLite Provide you with a brief overview of the SQLite and its important features such as serverless, self-contained, zero-configuration, and transactional. databases List names and files of attached databases Meta-commands are always prefixed with a dot (.).Ī list of available meta-commands can be viewed at any time by issuing the '.help' command. Perform administrative operations upon the attached databases (such as rebuilding indices). SQLITE META-COMMANDS The interactive interpreter offers a set of meta-commands that can be used to control the output format, examine the currently attached database files, or

$ sqlite3 -line mydata.db 'select * from memos where priority > 20 ' Multiple statements should be separated by semi-colons. Optionally, a SQL statement or set of SQL statements can be supplied as a single argument. This is useful for migrating data between databases, possibly changing the schema along the way. Multiple databases within the same interactive session. If no database name is supplied, the ATTACH sql command can be used to attach to existing or create new database files. Sqlite> insert into memos values('lunch with Christine', 100) Sqlite> insert into memos values('deliver project description', 10) Sqlite> create table memos(text, priority INTEGER) If the database file does exist, it will be opened.įor example, to create a new database file named 'mydata.db', create a table named 'memos' and insert a couple of records into that table: If the database fileĭoes not exist, it will be created. To start a sqlite3 interactive session, invoke the sqlite3 command and optionally provide the name of a database file.
