LDC-Q0002 — The query is missing a clause the language requires

What it means

A query is built from clauses in a fixed order: one or more sources first, an optional filter, then the list of values to return. When the text stops where the next clause should begin — a source with no variable, a filter with no condition, no return list at all — the engine reports the exact spot where it got stuck. Nothing is searched; the shape is wrong before any data is read.

Read the reported line and column: the token there is the first one the grammar cannot place. Add the missing clause and keep the rest as written.

Example

LawQL

select r

Fix

LawQL

from r in rules select r

Engine message

The engine reports this in its own wording:

Output

LDC-Q0002: the query requires at least one from clause (line 1, column 1).
