i hope can me these 2 queries query: select count(distinct id), sum(amount) sales year(saledate) = '2015' , saletype ='cash' group customer having sum(amount) >=500; select count(distinct id), sum(amount) sales year(saledate) = '2015' , saletype ='creditcard' group customer having sum(amount) >=1000; what best way combine them one? aim select cases customer paid more 500 in cash or more 1000 via creditcard. thanks lot help. in case can use example: select count(distinct id), sum(amount) sales year(saledate) = '2015' , saletype ='cash' group customer having sum(amount) >=500; union select count(distinct id), sum(amount) sales year(saledate) = '2015' , saletype ='creditcard' group customer having sum(amount) >=1000; or union if want records without distinct . select count(distinct id), sum(amount) sales year(saledat

what's cost/overhead of thread context switch? far know, there direct costs: saving , restoring context(generally,it includes general purpose registers , program counter) costs of thread scheduling(deciding thread next run) and there maybe indirect costs, such as: if thread switched out arranged run in cpu later, might re-load variables main memory(or other cpu via coherence protocol), cache read miss might occur. is there other indirect costs?

i'm trying rows column of type text[] contains value similar user input. what i've thought , done far use 'any' , 'like ' operator this: select * sometable '%someinput%' any(somecolum); but doesn't work. query returns same values query: select * sometable 'someinput' = any(somecolum); i've got result using unnest() function in subquery need query in clause if possible. why doesn't like operator work any operator , don't errors? thought 1 reason should any operator in right-hand of query, ... is there solution without using unnest() , if possible in where clause? it's important understand any not operator sql construct can used right of operator. more: how use instead of in in clause rails? the like operator - or more precisely: expression , rewritten ~~ operator in postgres internally - expects value left , pattern right. there no commutator operator (like there simple equali

i created simple report has 5 columns (companyname, bought, sold, returned, total) looks like. companyname bought sold returned total with exception of company name, every value number. created simple queries bought, sold , returned. total used arithmetic in main query (basically sum of bought, sold, returned (returned negative)). problem came across companies, of columns (bought,sold,returned) null since ex: don't have returned when run report, doesn't show me value total. unless have values in three(bought sold , returned) - nothing gets displayed in total. don't want display zeros in report because clustered, there way me convert null 0 when calculation , hide report?

anybody knows whether unitils project still alive. on there pages last version 3.3 in maven repository 3.4.2.(actually there google cached version of pages version said 3.4.2) anyway there replacement project. kind of lack vivid community around , don't want bound dying project. unitils seems abandoned nowadays. project available on github here , can @ history , activity. anyways 2 cents... unitils has serious drawbacks: integrates many third-party libs (easymock, dbunit, spring, dbmaintainer, xmlunit, slf4j etc) , forces versions - serious drawback due being dependent on many 3rd party libraries, impossible keep date without company behind. unitils 4.0 developed since 06.2011 , planned release @ 01.2012, (01.2016) after 4 years still not released. dbunit for database-driven apps may seem interesting way go plain dbunit + spring-test or alternatively 3rd party tools: excilys/spring-dbunit comes handy @dataset annotation , actively developed on

the minizinc ide has parallel solver option ("number of threads") in config section. when compiling commandline, however, mzn2fzn binary doesn't seem support parallel option. possible solve in parallel commandline-compiled file? you can either use minizinc via integrated development environment ( ide ) or via commandline call. using ide 2.0.8 in ide , use configuration tab specify number of threads used searching/solving. depending on selected backend, may end error message, multi-threading not supported respective backend. via commandline, can either call compiler , backend separately, or can use minizinc.exe act umbrella tool call them sequentially. tools have commandline option --help explain parameters. minizinc.exe accepts -p or --parallel run backend in multi-threading mode, provided supported.

i planning store query data in sqlite3 database. i have these fields in sqlite3 unix_epoch, cumulative_query_rate 1452128581, 150 1452128582, 190 1452128583, 220 1452128584, 270 i want queries-per-second column below: qps 0 40 30 50 how do in sqlite3. you have subtract value of previous second: select unix_epoch, (select t1.cumulative_query_rate - t2.cumulative_query_rate supersecrettablename t2 t1.unix_epoch - 1 = t2.unix_epoch ) qps supersecrettablename t1;

i have xslt key defined. need access key within for-each loop, loop processing node-set outside scope of key defined. snippet, i've marked 2 lines, 1 works , 1 not: <xsl:value-of select="key('name', 'use')"/> <!-- works --> <xsl:for-each select="$outofscopenodeset"> <xsl:value-of select="key('name', 'use')"/> <!-- not work --> </xsl:for-each> is there way access key within for-each loop? xslt 1.0, msxsl engine. (i not think of reasonable way provide full working example this. i'm not sure of correct terminology, such "scope" - perhaps if knew correct terminology i'd able find answer already. if question not clear enough please let me know , i'll try edit better shape.) in xslt 1.0, keys not work across documents. seems $outofscopenodeset contains node-set root node different root node of xml document being processed (probably created ex

i writing program have 2 listboxes same data 1 listbox items update student name , total score , other student name , each individual judge score next student name. going far stuck... have 2 methods save() , saveas() save() automatically writes data "formdata.bin" , saveas() lets user enter own file name. is possible re-write save() method when click save saves current data file open in ms word when typing in document , click save add new typed data current file. here save() method wrote. public void saveentry() { int itemscount = math.min(lstbxstudents.items.count, lstbxstudentscore.items.count); savefiledialog1.initialdirectory = application.startuppath; savefiledialog1.filename = "formdata.bin"; { try { using (filestream fs = new filestream(savefiledialog1.filename, filemode.create)) using (binarywriter save = new binarywriter(fs)) {

i looking create 26 separate sql databases, each same structure. (i.e. 1 each letter of alphabet), ideally can access dictionary or similar [i.e. access database corresponding letter a database["a"] ]. i have following code, generates 1 sql database (in case letter a) using peewee. from peewee import * database_location_a = "c:\\database\\a.db" data_sql_a= sqlitedatabase(database_location_a, threadlocals=true, pragmas=(("synchronous", "off"),)) class basemodel(model): class meta: database = data_sql_a class main_table(basemodel): file_name = charfield(primary_key = true) year = charfield() data_sql_a.connect() data_sql_a.create_tables([main_table]) there parts of code can loop on (e.g. can create dictionary of file locations). however, stuck given location coded class basemodel , how loop on [i.e. need 26 separate classes, , if so, can create without needing copy/paste class 26 times]? , similarly
