What SQL Query Builder does, with a checked example
SQL Query Builder composes a SELECT statement from choices instead of keystrokes: you pick the base table, tick the columns you want, add joins by naming the matching key columns on each side, then stack up WHERE conditions, GROUP BY, and ORDER BY. The finished statement appears as text you can copy into your own database client or application. The surprise is that the tool has no view of your data: table and column names are just text you type, so a misspelled column still builds a query that looks finished and only fails when you run it.
Worked example
A concrete input and expected output from the current implementation.
Input
In the builder: base table 'customers', select columns customer_id, name, country; add an INNER JOIN to 'orders' on customers.customer_id = orders.customer_id; add a WHERE condition country = 'US'; order results by name ascending.
->
Expected output
SELECT customers.customer_id, customers.name, customers.country
FROM customers
INNER JOIN orders ON customers.customer_id = orders.customer_id
WHERE customers.country = 'US'
ORDER BY customers.name ASC;
The statement is the direct composition of the four clauses you set, in the order SQL requires: SELECT, FROM, JOIN, WHERE, ORDER BY. The value 'US' is emitted as a quoted string literal because it is text, and columns are qualified with their table name so the join cannot create ambiguous references.
