Linux distributions put it in /etc/firebird/n.n where n.n is the version of the Firebird database server. There is more information on connecting to databases, using full paths or aliases, below. Chapter -x extract metadata -z show program and server version Not all of these switches appear in every release of Firebird. Some will be seen in more Command Line Switches 7 When the server provides line and column information, users can see the exact line of the DML in the script that caused the problem. When the server only indicates failure, users

Some keywords are reserved, meaning their usage as identifiers for database objects, parameter names or variables is prohibited in some or all contexts. Non-reserved keywords can be reserved words and keywords in the chapter Reserved Words and Keywords. 2.3. Identifiers All database objects have names, often called identifiers.

Документация по переходу с СУБД MS SQL Server, прежде всего, предназначена для помощи пользова- телям СУБД оценить, следует ли вообще осуществлять перехода, которые были наработаны различными пользователями при переходе на СУБД Firebird с СУБД MS SQL Server. Есть две вещи, на которые следует обратить внимание при переходе. Во-первых, проблемность переноса
