Nul-terminated. ** ** Followed by one or more entries associated with the table. ** ** 1 byte: Either SQLITE_INSERT (0x12), DELETE (0x09). ** 1 byte: Flag. 0x01 for REPLACE, 0x00 for OMIT. ** record: (in the record format defined above). ** ** In a rebase blob, the first field is set to SQLITE_INSERT if the change ** that caused the conflict was an INSERT or UPDATE, or to SQLITE_DELETE if ** it was a DELETE. The second field is set to 0x01 if the conflict ** resolution strategy was REPLACE, or 0x00 if it was OMIT. ** ** If the change that caused the conflict was a DELETE, then the single ** record is a copy of the old.* record from the original changeset. If it ** was an INSERT, then the single record is a copy of the new.* record. If ** the conflicting change was an UPDATE, then the single record is a copy ** of the new.* record with the PK fields filled in based on the original ** old.* record. */ /* ** For each row modified during a session, there exists a single instance of ** this structure stored in a SessionTable.aChange[] hash table. */ struct SessionChange { |
