SQL is designed for managing or stream processing data in an RDBMS. This package provides a set of functions to generate SQL commands for creating tables, inserting data, and performing various operations, including text search and matching, on SQL databases (PostgreSQL).

import * as xsql from "jsr:@nodef/extra-sql";

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

xsql.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
// → ($$F1$$, $$Mango$$),
// → ($$F2$$, $$Lychee$$);


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

xsql.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');
