- org.hibernate.query.sqm.function.AbstractSqmFunctionDescriptor
-
- org.hibernate.query.sqm.function.JdbcEscapeFunctionDescriptor
-
- All Implemented Interfaces:
SqmFunctionDescriptor
public class JdbcEscapeFunctionDescriptor extends AbstractSqmFunctionDescriptor
Acts as a wrapper to anotherSqmFunctionDescriptor
, rendering the standard JDBC escape sequence{fn f(x, y)}
around the invocation syntax generated by its delegate.
