Обсуждение: Protocol & Transmitted Field Data
Hi everyone, I have a question regarding field format used to transmit data (when data is transmitted over the protocol): Is there a way to change field format used by database to transmit data from text to binary? Whats happening: I have 2 columns in a table, both integers, when they transmitted over to client, their values transmitted as a collection of characters e.g. number 1234567 represented as '1' '2' '3' '4' '5' '6' '7' instead of using 4 bytes for int4 Thanks! |

You can also request the results in either binary or text: http://www.postgresql.org/docs/9.0/static/libpq-exec.html Cheers, Ken
