Hi, I'm using a Cassandra table to store some data. I created the table like this: CREATE TABLE IF NOT EXISTS table_name (s BLOB, p BLOB, o BLOB, c BLOB, PRIMARY KEY (s, p, o, c));
I need the at least the p column to be sorted, so that I can use it in a WHERE clause. So as far as I understand, the s column is now the row key, and (p, o, c) is the column name. I tried to delete single entries with a prepared statement like this: DELETE p, o, c FROM table_name WHERE s = ? AND p = ? AND o = ? AND c = ?; That didn't work, because p is a primary key part. It failed during preparation. I also tried to use variables like this: DELETE ?, ?, ? FROM table_name WHERE s = ?; This also failed during preparation, because ? is an unknown identifier. Since I have multiple different p, o, c combinations per s, deleting the whole row identified by s is no option. So how can I delete a s, p, o, c tuple, without deleting other s, p, o, c tuples with the same s? I know that this worked with Thrift/Hector before. Regards, Sebastian
