Jaybird 2.1 JDBC driver Java Programmer's Manual - Firebird

{fn (argument list)}
For example {fn concat('Firebird', 'Java')} concatenates these two words
into 'FirebirdJava' literal. “Ошибка: источник перекрестной ссылки не
найден” provides a list of supported scalar functions.
Date and Time Literals
It is allowed to include date and time literals in SQL statements. In order to
guarantee that each database will interpret the literal identically, the JDBC
specification provides following syntax to specify them:
Date literal escaped syntax:
{d 'yyyy-mm-dd'}
Time literal escaped syntax:
{t 'hh:mm:ss'}
Timestamp literal syntax (fractional seconds part '.f...' can be omitted):
{ts 'yyyy-mm-dd hh:mm:ss.f...'}
Outer Joins
Due to the various approaches to specify outer joins (for instance, the Oracle “(+)”
syntax), the JDBC specification provides the following syntax:
{oj }
where the outer join is specified as
::=
{LEFT|RIGHT|FULL} OUTER JOIN
{ | } ON
An example SQL statement would look like this:
SELECT * FROM {oj tableA a
LEFT OUTER JOIN tableB b ON a.id = b.id}
Stored Procedures
The escaped syntax for stored procedures is described in details in the XXX
where CallableStatetent is covered.
LIKE Escaped Characters
The percent sign (%) and underscore (_) characters are wild cards in LIKE clause
of the SQL statement. In order to interpret them literally they must be preceded by
the backslash character (\) that is called the escape character. The escaped syntax
for this case identifies which character is used as an escape character:
{escape ''}
