我試圖從Grails應用程序查詢存儲與postgres ltree類型的物化路徑。不幸的是，我的查詢使用「？」這是由GORM捕獲作爲參數逃跑？ （問號）在休眠/ gorm sql限制
sqlRestriction("materialized_path ? (SELECT ARRAY(SELECT CAST(CAST(subpath(?,0,generate_series) AS text) ||'.*{1}' AS lquery) FROM generate_series(1,nlevel(CAST(? AS lquery)))))"
,[vertex.materializedPath,vertex.materializedPath])
如果是第一個問號應該逃脫，被拋出的錯誤操作是
org.postgresql.util.PSQLException: No value specified for parameter 4.
