sqlite

Allows to perform queries on data stored in a SQLite database.

Syntax

sqlite('db_path', 'table_name')

Arguments

• db_path — Path to a file with an SQLite database. String.
• table_name — Name of a table in the SQLite database, or a query passed to SQLite as is (see Passing a query instead of a table name). String.

Returned value

• A table object with the same columns as in the original SQLite table.

Passing a query instead of a table name

Instead of a table name, the second argument can be a SELECT query that is passed to SQLite as is. The structure of the resulting table is inferred from the query result. The query can be written either as a subquery, or wrapped into the query function:

SELECT * FROM sqlite('sqlite.db', (SELECT col1, col2 FROM table1 WHERE col2 > 1));
SELECT * FROM sqlite('sqlite.db', query('SELECT col1, col2 FROM table1 WHERE col2 > 1'));

Such a table is read-only: INSERT into it is not allowed. The same syntax is supported by the SQLite table engine.

Example

SELECT * FROM sqlite('sqlite.db', 'table1') ORDER BY col2;

┌─col1──┬─col2─┐
│ line1 │    1 │
│ line2 │    2 │
│ line3 │    3 │
└───────┴──────┘
