I'm trying to get the field default value from RDB$RELATIION_FIELDS.RDB$DEFAULT_VALUE which is stored as a BLOB type 2 -BLR.
Say I have a String or an Integer set as a default value, I don't know how to read the BLOB BLR to get this value. I know it is possible since Database Workbench displays the value. How can I get the field default value?
