sqlc support for query with conditional/optional join

[Chakra513]

Hello All,
Quick question. Not sure if this is exactly sqlc thing or something beyond. Migrating a go code from using sql boiler ( where query is constructed on the fly that does a join optionally based on argument not being null ) to sqlc.

Basically a query where the join is conditional upon an argument passed being not-null.

I have a dumb down sample query to test out conditional join in sqlc, but it errors out. What to know if this is supported.

Thank you for your help.

Query:

-- name: TestJoin :many
SELECT * FROM authors
CASE
 WHEN 1=1 THEN INNER JOIN addr ON name = addr.name
END
;

sqlc error:

sqlc generate failed.
# package 
query.sql:3:2: syntax error at or near "CASE"
