SQL escape sequences for JDBC

Language features, such as outer joins and scalar function calls, are commonly implemented by database systems. The syntax for these features is often database-specific, even when a standard syntax has been defined. JDBC defines escape sequences that contain the standard syntax for the following language features:
*Date, time, and timestamp literals
*Scalar functions such as numeric, string, and data type conversion functions
*Outer joins
*Escape characters for wildcards used in LIKE clauses
Note: The Progress DataDirect MongoDB for JDBC driver also supports the custom function escape CAST_TO_NATIVE.
The escape sequence used by JDBC is:
{extension}
The escape sequence is recognized and parsed by the drivers, which replaces the escape sequences with data store-specific grammar.
* Date, time, and timestamp escape sequences
* Scalar Functions
* Outer Join Escape Sequences
* LIKE escape character sequence for wildcards
* Procedure call escape Sequences
