in application users can create custom tables 3 column types. text, numeric , date can have 20 columns. create sql table based on schema using nvarchar(430) text, decimal(38,6) numeric , datetime. along identity id column. there potential many of these tables created different users , data might updated users uploading new csv files. best performance during upload of user data truncate table rid of existing data batches of bulk insert. the user can make selection based on filter build can include number of columns. issue tables lot of rows have poor performance during selection. combat thought adding indexes don't know columns included in condition have index every column. for example on local sql server 1 table on million rows , condition on 6 of columns take around 8 seconds first time runs under 1 second subsequent runs. indexes on every column run in under 1 second first time query ran. performance issue amplified when test on sql azure database same query take on min...

i have mongoose.schema this: const pixelschema = mongoose.schema({ x: string, y: string, color: string, }); also have array of objects this: let pixels = [ {x: 0, 1: 0, color: 'blue'}, {x: 0, y: 1, color: 'blue'}, {x: 0, y: 2, color: 'blue'}, ] how can check 1 of elements exist in database? solution looks this, think it's inefficient. pixels.map(pixel => { pixel.find(pixel, (err, pixels) => { if (pixels) { console.log('find!'); } }); }); use array part of $or query document. $or operator lets perform logical or operation on array of 2 or more expressions , selects documents satisfy @ least 1 of expressions. so query in end should be: let pixels = [ {x: 0, y: 0, color: 'blue'}, {x: 0, y: 1, color: 'blue'}, {x: 0, y: 2, color: 'blue'}, ]; let query = { "$or": pixels }; pixel.find(query, (err, pixels) => { if (pixels) { console.log(...

i've searched around here haven't found satisfying answer i've decided ask. need search collection of strings find expressions like: ab 12345 ac 12345 i've tried regex [a][bc][ ]\d{5} but unfortunately in strings there also #xxab 1234567890123 ggab 12345678901 ab 123456 sab 123456789 and above expression gets these valid. i've found , tried [a][bc][ ]\d{5}$ but not match anything. so question is, there expression find strings 5 numbers followed except more numbers? from answers think not clear in exposition, strings in middle of larger string set possible string must match: my description data xxxab 12345bcd and also my second description data ref. ab 12345 and also my third description data refab 12345 and also ab 12345with description following ab 12345 space , description following the strings uppercase in database. use ?! lookahead. a[bc] \d{5}(?!\d) see demo. https://regex101.com/r/or7zj6/2

i googled store pin in key store . got confused of solution. here question :- i have encrypted pin (string). how store in keystore , retrieve it. know shared preference , local storage. heard key store more secure. so question how store string in keystore , retrieve it. the android keystore system lets store cryptographic keys in container make more difficult extract device. once keys in keystore, can used cryptographic operations key material remaining non-exportable. moreover, offers facilities restrict when , how keys can used, such requiring user authentication key use or restricting keys used in cryptographic modes. see security features section more information. the keystore system used keychain api android keystore provider feature introduced in android 4.3 (api level 18). document goes on when , how use android keystore provider. here have data need how right! click here hope it's :)
