ESQL nor ISQL flavours are described here unless mentioned explicitly. 2.1.2. SQL Dialects SQL dialect is a term that defines the specific features of the SQL language that are available when Chapter Three dialects are available: • Dialect 1 is intended solely to allow backward comptibility with legacy databases from very old InterBase versions, v.5 and below. Dialect 1 databases retain certain language language features that differ from Dialect 3, the default for Firebird databases. ◦ Date and time information are stored in a DATE data type. A TIMESTAMP data type is also available, that is identical

two SQL “dialects”: dialect 1 and dialect 3. New databases should always be created with dialect 3, which is more powerful in a number of respects. Dialect 1 is a compatibility dialect, to be used only Generator Basics 4 under InterBase 5.6 or earlier. One of the differences between the two is that dialect 1 has no native 64-bit integer type available. NUMERIC(18) columns for instance are stored internally biggest integer type in dialect 1 is the 32-bit INTEGER. In dialect 1 as in dialect 3, generators are 64-bit. But if you assign the generated values to an INTEGER column in a dialect 1 database, they are
