I am using FR v2.1.6. I tried to use clause like `%{sql: SELECT ...}`. But length of SQL-query is so large for using as field of SQL-table. And I thought that I can create variable like myquery = "SELECT ..." as entry of configuration file, and to use this as `%{sql:${myquery}}`. But it didn't work. I looked into log: [sql] expand: ${myquery} -> {myquery} rlm_sql_postgresql: Status: PGRES_FATAL_ERROR What's wrong?
