How it works

Selected columns, sources, joins, predicates, grouping, ordering, limits, and parameters are serialized in SQL clause order. Values can remain placeholders instead of being interpolated into the statement.

  • Parameters reduce injection risk.
  • Clause order mirrors the relational query model.

Worked example

Build SELECT with Filter
Build a SELECT query with WHERE clause and ORDER BY
Input
											Table: users
Operation: select
Columns: name, email
Where: active = true
Order by: name
Limit: 20
Output
												SELECT name, email
FROM users
WHERE active = true
ORDER BY name
LIMIT 20;

When to use this

API endpoints, reports, and database consoles build SELECT statements.

Edge cases

  • NULL needs IS NULL rather than = NULL.
  • A right-table predicate in WHERE can turn a left join into an inner join.
  • Identifier interpolation has different safety rules from value parameters.
