Last already commited transaction CN. SNAPSHOT_CN - what it is? As i do not understand description from README.context_variables2 It was renamed to SNAPSHOT_NUMBER, btw. Documentation say: SNAPSHOT_NUMBER | Value of Snapshot Number of currently database snapshot: either | transaction level (for SNAPSHOT or CONSISTENCY transaction), | or request level (for READ COMMITTED READ CONSISTENCY | transaction). NULL, if snapshot is not exist. What is not clear here ? 2. Is there a way to read transaction CN by transaction number? See RDB$GET_TRANSACTION_CN, described at doc/sql.extensions/README.builtin_functions.txt i need some function which can be used in sql query e.g.: select * from MY_TABLE T WHERE transactionCN(T.RDB$RECORD_VERSION)>:XXX Regards, Vlad Firebird-Devel mailing list, web interface at https://lists.sourceforge.net/lists/listinfo/firebird-devel

Combine embeddedd files into one dll Key: CORE-6200 URL: http://tracker.firebirdsql.org/browse/CORE-6200 Project: Firebird Core Issue Type: New Feature Reporter: Clyde Eisenbeis It would be good if the necessary files for embedded were combined into one dll.
