Package org.hibernate.dialect.function

Class DB2FormatEmulation

java.lang.Object

org.hibernate.query.sqm.function.AbstractSqmFunctionDescriptor

org.hibernate.dialect.function.FormatFunction

org.hibernate.dialect.function.DB2FormatEmulation

All Implemented Interfaces:

FunctionRenderer, FunctionRenderingSupport, SqmFunctionDescriptor

public class DB2FormatEmulation
extends FormatFunction

DB2's varchar_format() can't handle quoted literal strings in the format pattern. So just split the pattern into bits, call varcharformat() on the odd-numbered bits, and concatenate all the nonempty bits at the end.
