is there way handle reserved table & column names in app can work through kinds of databases oracle, mysql, sql server, postgresql etc. currently, have following : oracle - use double quotes. mysql - use backtick or double quotes (depends if ansi_quotes mode enabled) sql server - use brackets postgresql - use double quotes. i aware ansi standard states use double quotes unfortunately not dbms seem support them. use double quotes. that's standard says, , surprisingly, works on platforms. require mysql have ansi_quotes enabled, or set @ session level : set session sql_mode = 'ansi' (i used ansi not ansi_quotes here because makes mysql bit saner). postgresql doesn't require special settings identifiers (though old versions need standard_conforming_strings = on handle literals sensibly). neither oracle. modern ms-sql shouldn't require special settings support double quoted identifiers : when set quoted_identifier on (default)...

my query select distinct on large database, , in pgadmin sql tool query lasts 12 sec. select distinct on (city, airport, zip, country, name) city, airport, price, id mytable; the spring-batch reader definition: jpapagingitemreader<myentity> reader; reader.setpagesize(page_size); if define page_size large database columns, performance equal 12 sec. if set size lower value (eg pagesize = 100.000 on 1.000.000 datarows db), performance bad (~ 10x long). spring-batch applies specific pagination on queries in background. does: query.setfirstresult(); query.setmaxresult(); if page size 10, den queries executed follows: firstresult, maxresult 0, 10 10, 10 20, 10 30, 10... this again translates limit , offset in sql. question: select distinct on not combinable pagination limit/offset? me seems if full select distinct query executed again on each "pagination" run, , lasts long. so, if database must anyhow make full distinct select be...

if define union traversing data structure squentially ( start , end offset) or via pointer tree structure depending on number of data elements on 64 bit system these unions aligned cache lines, there possibility of both adding 1 bit flag @ 1 of 64 bits in order know traversal must used , still allowing reconstruct right pointer? union { uint32_t offsets[2]; tree<nodedata> * tree; }; it's system dependent, don't think 64-bit system uses full pointer-length yet. also, if know data 2 n -aligned, chances n bits sitting idle there (on old systems not exist. don't think of 64-bit systems, , anyway no longer of interest). as example, x86_64 uses 48bits, upper 16 must same bit47. (sign-extended) example, arm64 uses 49bits (2 mappings of 48bit @ same time), there have 15 bits left. just remember corect pilfered bits. (you might want use uintptr_t instead of pointer, , convert after correction.) using mis-aligned or impossible pointer causes be...
