the title may misleading, i'm unsure of way of phrasing it. query below works intended if little slow. however, when try wrapping insert into around query, locks database. table1 contains less 1,000 records , table2 less 1,500 records. the objective of query match records based on date/time groups contained in columns tables 1 , 2. crux of problem getting result set unique table can exported. this query variation of find here , may clarify intentions: https://social.msdn.microsoft.com/forums/office/en-us/1305b3a9-94c9-4e7c-a5fe-7b64a79600ca/select-closest-earlier-date . change rather looking closest date after, i'm retrieving closest day prior. select table1.*, ( select table2.column1 table2 table2.column1 = ( select max(t.column1) table2 t t.column1 <= table1.column1)) tempcol table1 are there alternatives can attempt break sql or option let run until it's complete? example of output: table1.id table1.column1 t.column1 1 ...

let's suppose have array (myarray) data this: 0: myarray content: 'something' date: '15.5.2015' name: 'abc' 1: myarray content: 'text' date: '15.5.2015' name: 'bla' 2: etc ... now rewriting values (into e.g. empty string) of 1 object properties in array (for example: 'content') use loop this: for(var = 0; < myarray.length; i++){ myarray[i].content = ''; } so result of be: 0: myarray content: '' date: '15.5.2015' name: 'abc' 1: myarray content: '' date: '15.5.2015' name: 'bla' 2: etc ... my question is: possible same result without using loop in javascript? this: myarray[all].content.rewriteinto(''); tnx ideas. anything end looping in fashion. however, you don't have loop... because have functional array methods! you're looking map or reduce , perhaps both, since want transform (map)...

i wondering there other way to check our slow queries without logging slow query. suppose, have highily busy server can't afford log save memory , i/os. then, there other way available check if have slow query? know, can profiling of query still not sure identify query 1 taking of time , memory. just started mysql administration , not sure how handle this. guidance highly appreciated. i find slow best source of bogging down server. suggest start moderately high value of long_query_time. minimize i/o , disk space. fix queries finds, if can. when have exhausted that, lower setting find more. use pt-query-digest find "worst" queries. keep in mind high value finds long queries, if rare. lower value find fast queries run frequently, , these may real villains. another approach turn on slowlog briefly or during relatively idle time. find may still useful. anecdote: in 1 system there query where misformulated such running 100% cpu. one-line fix d...
