This is contrary to the SQL standard — double quotes are reserved for a distinct syntactic purpose both in standard SQL and in Dialect 3. Double-quoting strings is therefore

The translated text would be edited and converted to the Project’s standard DocBook format for addition to the open document library of the Firebird Project. From there, the source text would be available available for translation into other languages for addition to the library. The fund-raising campaign happened at the end of 2014 and was successful. In June, 2015, professional translator Dmitry Borodin English, editing of the raw, translated text and conversion of the whole into the Firebird Project’s standard DocBook 4 documentation source format.

Changes to Note in V.2.1 Metadata Need to be Upgraded If your databases contain text BLOBs storing non-ASCII connectivity layers (drivers, components). Details are in Chapter 3 of the V.2.1.2 Release Notes, in Changes to the Firebird API and ODS. The FIREBIRD Variable FIREBIRD is an optional environment variable

Mint Linux — based on Ubuntu — have renamed Firebird’s isql to be isql-fb. There may be similar changes in other distributions. In addition, not all distributions install Firebird to the same location file -i(nput) input file (set input) -m(erge) merge standard error -m2 merge diagnostic -n(oautocommit) no autocommit file. The resultant information can be used to view all the changes made to the database since its creation. Before making any more changes, create a new database with identical schema definitions or

through the entire set. 5.3.2. SINGULAR SINGULAR is an InterBase/Firebird extension to the SQL standard. It is often described as returning true if exactly one row in the subquery meets the search condition defined in separate modules. Firebird ships with two UDF libraries: ib_udf (a widely used “InterBase library”) and fbudf. You can add more libraries, e.g. by buying or downloading them, or by writing them (UDFs) 38 “by descriptor”. Descriptors allow NULL signalling no matter the type of data. The fbudf library makes ample use of this technique. Unfortunately, using descriptors is rather cumbersome; it’s

Standard Database Page Header Every page in a database has a 16-byte standard page header. Various page types have an additional header that follows on from the standard one. The C code code representation of the standard header is: struct pag { SCHAR pag_type; UCHAR pag_flags; USHORT pag_checksum; ULONG pag_generation; ULONG pag_scn; ULONG reserved; }; pag_type

the second file name supplied on the command line.  You may, if you wish, send the output to standard output rather than a backup file. In this case, you must specify stdout as the dump file name. (across two different databases) that failed because a server died before the commit, but after the changes were made, you have a limbo transaction. This switch forces the backup to ignore data from such second file name on the command line.  You may, if you wish, read the dump data directly from standard input rather than a backup file. In this case, you must specify stdin as the dump file name. You
