How your data is typed in SQLite3
Generated from the converter's own SQLite3 type mapping — this is what it actually emits, not an example.
| Your data | SQLite3 type |
|---|---|
| Whole number | BIGINT |
| Decimal (money) | NUMERIC(10,2) |
| Floating point | REAL |
| True / false | BOOLEAN |
| Date | DATE |
| Date and time | TIMESTAMP |
| Short text | TEXT |
| Long text | TEXT |
| Binary data | BLOB |
Working from a SQL dump file
A dump is a schema and its data written out by a database's own export tool, in that tool's own flavour of SQL. Which flavour it is has to be established before a single line of it can be parsed correctly.
- →The dialect is decided by scanning the first 5,000 characters for tell-tale syntax: AUTO_INCREMENT or ENGINE= means MySQL, SERIAL means PostgreSQL, IDENTITY( or NVARCHAR means SQL Server.
- →If your dump opens with thousands of characters of comments and SET statements before the first CREATE TABLE, that scan has nothing to go on and falls back to MySQL. Trimming the preamble fixes it.
- →Dump tools often gzip their output. A .sql.gz is not a recognised extension, so decompress it before uploading.
The .sqlite3 name and what carries over
The 3 in sqlite3 is the file format version and the name of the command-line tool, not a property of your conversion. One database file arrives, and the two things worth knowing about it are what it is called and what it leaves behind.
- →The file inside the zip is always database.sqlite, whichever spelling brought you to this page. Rename it to database.sqlite3, or to whatever a framework expects, once you have it - the header is what identifies it, never the extension.
- →An auto-increment column arrives holding all of its values and nothing that assigns new ones. No AUTOINCREMENT keyword is written, and the column is declared BIGINT rather than exactly INTEGER, so it is not an alias for the rowid either: rows you insert later have to supply their own key.
- →Only the rows are transactional. The very first CREATE TABLE runs in autocommit, and everything after it - that table's rows, and every later table - sits in one transaction that commits after the last row. A conversion that fails partway therefore leaves a file holding an empty shell of the first table and nothing else. You never receive that file: the zip is only assembled once the writer has returned.
Reading SQL dump file
- →Parsed with a real SQL parser, not regular expressions, so a value containing a closing parenthesis or a semicolon cannot split a row in half.
- →CREATE TABLE types, primary keys, NOT NULL and AUTO_INCREMENT are all read from the dump.
- →The source dialect is detected from the dump itself — MySQL, PostgreSQL and SQL Server dumps all parse.
Writing SQLite3
- →Columns get real declared types rather than everything being TEXT.
- →Primary keys and NOT NULL constraints are preserved.
- →A money column is declared NUMERIC(10,2), but that declaration does not stop SQLite’s own numeric affinity from converting the inserted value into a float once it lands, so 19.99 can come back with a rounding tail. Pick the DuckDB target instead when the exact decimal has to survive.
What you get
A ZIP containing database.sqlite. If anything about your data needed a judgement call, a _warnings.txt explains it.
Questions
- Is converting SQL dump file to SQLite3 free?
- Yes. Files up to 10MB convert free with no account. There is a limit of five conversions per day per IP address.
- Will my SQL dump file data keep its types in SQLite3?
- Yes — that is the point. Whole numbers, decimals, dates and booleans are mapped to real SQLite3 types rather than everything becoming text. The mapping table above shows exactly what you get.
- Do you store my file?
- No. The file is written to a temporary directory, converted, and the directory is deleted as soon as your download has been sent.
