common_sql_sqlite

SQLite driver for common_sql, implemented with sqlight.

For usage documentation, examples, and the full API reference, see the common_sql README.

This package exposes a single driver() function. Add it alongside common_sql:

gleam add common_sql common_sql_sqlite

import common_sql as sql
import common_sql_sqlite

pub fn main() {
  let driver = common_sql_sqlite.driver()
  use conn <- sql.with_connection(driver, "file:mydb.sqlite3")
  // see common_sql README for full examples
}

SQL placeholders

Use sql.Sql("… WHERE id = ?") for SQLite-native syntax. Use sql.Portable("… WHERE id = $1") to write queries in PostgreSQL style — the driver converts $1, $2, … to ? automatically, so the same string works across both SQLite and PostgreSQL drivers.

Limitations of sql.Portable()

$N inside SQL string literals is not distinguished from a real placeholder.

SQLite connection strings

See the SQLite URI documentation. Common examples:

"file:mydb.sqlite3"             // file-based database
":memory:"                      // in-memory (useful for tests)
"file:memdb1?mode=memory&cache=shared"  // named shared-memory
"file:data.db?mode=ro"          // read-only

Booleans: SQLite has no native boolean type. PBool(True) is stored as 1, PBool(False) as 0. Read boolean columns back with sqlight.decode_bool() or decode.int.

Development

Requires a C compiler for the esqlite NIF.

gleam test   # run the integration tests
gleam build  # compile the package
