SqlFormat() generates some trash characters with Date and Time arguments.
As a result, you can not use dates and times in your SQL queries.
Here is the testcase:

#include <Core/Core.h>
#include <Sql/Sql.h>

using namespace Upp;


CONSOLE_APP_MAIN
{
	Date sysdate = GetSysDate();	
	String s = SqlFormat(sysdate);
	Cout() << "Todays date is: " << s;
	while(1)
		Sleep(1000);
}

As a fast hack, I use this code in SqlCase.cpp

String SqlFormat(Date x)
{
	return FormatDate(x, "'YYYY-MM-DD'");
	//return MakeSqlValue(SQLC_DATE, x);
}

String SqlFormat(Time x)
{
	return FormatTime(x, "'YYYY-MM-DD hh:mm:ss'");
	//return MakeSqlValue(SQLC_TIME, x);
}

But I think, this should depend on current database handler.

Sorry, I should have perhaps renamed (or hide) SqlFormat.

It works OK. Just it creates the text that is to be compiled for target RDBMS (those odd characters...).

Use SqlCompile to get the final text.
