There is the Firebird Wire protocol documentation, but it doesn't contain all details and is mostly based on reverse engineering the protocol on a message level, not so much the content of the messages. You'll have more luck looking at the Firebird implementation, or other drivers like Jaybird. In any case, you need to encode a boolean as a single byte byte-array with the value 0 for false or 1 for true. See also: https://github.com/FirebirdSQL/jaybird/blob/master/src/main/org/firebirdsql/gds/ng/DefaultDatatypeCoder.java#L358 For reading and writing you also need information on the blr calculations: https://github.com/FirebirdSQL/jaybird/blob/master/src/main/org/firebirdsql/gds/ng/wire/DefaultBlrCalculator.java And reading: https://github.com/FirebirdSQL/jaybird/blob/master/src/main/org/firebirdsql/gds/ng/wire/version10/V10Statement.java#L516 And writing: https://github.com/FirebirdSQL/jaybird/blob/master/src/main/org/firebirdsql/gds/ng/wire/version10/V10Statement.java#L564 I'd also suggest to take a look at the commit for Jaybird I linked in ticket, as that includes all the changes you need to get it working. > And also I have doubts about an implementation of reading boolean fields. See above.
