r - ROracle: dbGetQuery works but dbListTables and other functions do not -


i installed roracle (following directions in package) , connected our oracle database.

i can run queries, using dbgetquery, , results fine, e.g.:

> dbgetquery(con, "select count(*) table_name")   count(*) 1     6111

however, of other dbi/roracle helper functions give no results:

> dblisttables(con) character(0)  > dbreadtable(con, "table_name") error in .oci.getquery(con, qry) :    ora-00942: table or view not exist

any ideas may cause?

in both cases, work me if specify schema argument, i.e.

dblisttables(con, schema = "my_schema") dbreadtable(con,"table_name",schema = "my_schema")

additionally, appears reading ?dblisttables has all , full arguments control whether in schemas, , whether return full schema name or table name.
