SQL is designed for managing or stream processing data in an RDBMS. Includes SQL command generation functions, with a few for text matching (PostgreSQL).

const sql = require('extra-sql');

sql.tableExists('food');
// SELECT EXISTS (SELECT 1 FROM information_schema.tables WHERE table_name='food');

sql.setupTable('food', {code: 'TEXT', name: 'TEXT'},
  [{code: 'F1', name: 'Mango'}, {code: 'F2', name: 'Lychee'}]);
// CREATE TABLE IF NOT EXISTS "food" ("code" TEXT, "name" TEXT);
// INSERT INTO "food" ("code", "name") VALUES
// ('F1', 'Mango'),
// ('F2', 'Lychee');

sql.selectTsquery('columns', 'total fat');
// SELECT * FROM "columns" WHERE "tsvector" @@ plainto_tsquery('total fat');

sql.matchTsquery('columns', ['total', 'fat']);
// SELECT *, '2'::INT AS "matchTsquery" FROM "columns" WHERE "tsvector" @@ plainto_tsquery('total fat') UNION ALL
// SELECT *, '1'::INT AS "matchTsquery" FROM "columns" WHERE "tsvector" @@ plainto_tsquery('total');
