sql - Creating a foreign key constraint with non-matching data -


greetings!

i have inserted data sql insert files ms sql database. apperantly data not complete. discovered when trying make erd , create key constraints between tables. when try connect article_review order1 order1 has primary key , article review has foreign key.

i have query selects records non-matching key values: see image: http://imgur.com/vdbcug8

so want now: insert new rows article_review missing id values. values of other columns not matter, can null or random generated.

a simple join won't cut because of other columns non-identical.

ps. above needed because ms sql 2016 wont let me create key constraint between 2 tables 1 of them contains value not in other 1 , throws error:

'order1' table saved 'article_review' table saved 'review' table - unable create relationship 'fk_review_order1'.   alter table statement conflicted foreign key constraint "fk_review_order1". conflict occurred in database "superdatabase", table "dbo.order1", column 'id'.

do want add foreign key documentation only?

you add fk this:

alter table dbo.order1 nocheck  add constraint fk_review_order1 foreign key (id) references dbo.article_review (id)

note with nocheck

this way foreign key created, not trusted , disabled, can seen query:

select schema_name(fk.schema_id) sch, t.name,         fk.name, is_disabled, is_not_trusted, fk.is_not_for_replication    sys.foreign_keys fk (nolock)         inner join sys.tables t (nolock) on t.object_id = fk.parent_object_id   fk.is_not_trusted = 1         , fk.is_disabled = 0 order schema_name(fk.schema_id), t.name, fk.name;

java - pagination of xlsx file to XSSFworkbook using apache POI -

right in code, reading xlsx file, xssfworkbook, , writing database. but, when size of xlsx file increases, causes outofmemory error. can not increase server size, or divide xlsx file pieces. tried loading workbook using file (instead of inputstream), didn't either. i looking way read 10k rows @ time (instead of entire file @ once) , iteratively write workbook , database. is there way apache poi? poi contains called "eventmodel" designed purpose. it's mentioned in faq : the ss eventmodel package api reading excel files without loading whole spreadsheet memory. require more knowledge on part of user, reduces memory consumption more tenfold. based on awt event model in combination sax. if need read-only access, best way it. however, may want double check first if issue somewhere else. check out this item : i think poi using memory! can do? 1 comes quite lot, reason isn't might think. so, first thing check - what's source of prob...

Unlimited choices in BASH case statement -

consider simple bash snippet: case $option in 1) image=${options[0]%.tar} ;; 2) image=${options[1]%.tar} ;; 3) image=${options[2]%.tar} ;; 4) image=${options[3]%.tar} ;; *) echo "invalid option" exit 1 esac in real script numbers goes 30. makes pretty long. can somehow specify cases variable? something this: case $option in $i) image=${options[$(($i-1))]%.tar} any pointer appreciated. you can match against multiple patterns in single clause: case $option in 1|2|3: echo "$option one, 2 or three" ;; esac if still typing you, can use simple pattern matching: case $option in # following matches # - single-digit numbers 0-9 # - two-digit numbers starting either 1 or 2 # - number 30 [0-9]|[12][0-9]|30) image=${options[$(($option-1))]%.tar} ;; *) echo "invalid option" 1>&2 exit 1 esac

apache - How do I stop my index.php being run twice for every user -

we've got webapp initial html served using apache , php. i noticed index.php being run twice every request. seems caused / effected rewrite rules in our .htaccess - rewritecond %{http_host} ^(www\.|hotels\.)ourdomain\.com$ [nc,or] rewritecond %{server_name} ^(www\.|hotels\.)ourdomain\.com$ [nc] rewriterule (.*) http://ourdomain.com/$1 [r=301] rewriterule ^hotels/([^/]+)/?\??(.*)$ ?d=$1&$2 [qsa] the final rule moving parameter url path query string. i.e. http://ourdomain.com/hotels/vegas?someparam=1 becomes http://ourdomain.com?d=vegas&someparam=1 if go directly query string version index.php run once. if use url redirected, index.php run twice (i'm checking adding error_log('end of index.php') file). so example going http://ourdomain.com/hotels/paris hits file twice http://ourdomain.com?d=paris hits once. i've seen this question , had @ blog mentioned , , can't find empty string url's (i've tried using yslow process). ...
