Description

Version

1.29.0

What happened?

Writing a query that uses the form:

SELECT 
 col1,
 col2,
 ...
WHERE NOT EXISTS (
 SELECT 1 FROM "table" WHERE "table"."id" = sqlc.arg('tableId')
);

Will copy over the expr after the WHERE as is, and neither replace the sqlc.arg with a placeholder nor extract that arg as a param for the query.

Relevant log output

N/A

Database schema

CREATE TABLE IF NOT EXISTS "rels" (
 "id" text PRIMARY KEY NOT NULL,
 "type" integer NOT NULL,
 "left" text NOT NULL,
 "right" text NOT NULL,
 "metadata" blob,
 "created" integer NOT NULL
) STRICT;

SQL queries

-- name: InsertPostReact :exec
INSERT INTO "rels" (
 id,
 type,

 sqlc.arg('left'),
 sqlc.arg('right'),
 sqlc.arg('metadata'),
 sqlc.arg('created')
WHERE NOT EXISTS (
