JDBC Escape Syntax

JDBC provides a way of smoothing out some of the differences in the way different DBMS vendors implement SQL. This is called escape syntax. Escape syntax signals that the JDBC driver, which is provided by a particular vendor, scans for any escape syntax and converts it into the code that the particular database understands. This makes escape syntax DBMS-independent.

A JDBC escape clause begins and ends with curly braces. A keyword always follows the opening curly brace:

{keyword }
Note: GemFire XD returns the SQL unchanged in the Connection.nativeSQL call, since the escape syntax is native to SQL. In addition, it is unnecessary to call Statement.setEscapeProcessing for this reason.

GemFire XD supports only the following JDBC escape keywords, which are case-insensitive.
