SQL Server Bulk Insert Update from CSV? -

-

i'm importing csv file sql server. problem need update if rows found, haven't found insert update equivalent or similar it.

this current code:

bulk insert actuals_financials_temp '\\strmv3302\temp\actuals_financials_temp.csv'   (fieldterminator = ',', rowterminator = '\n', firstrow = 2)

is there way update rows matching keys? or @ least ignore them rest uploaded , bulk update?

not directly, no. need bulk insert staging table , update existing records , insert missing records. try local temp table (i.e. #tablename) first.

technically speaking, either of following (both of use openrowset):

  • skip staging table , use openrowset(bulk...) update , insert queries. have tested, though, see if cost of reading file twice worth savings of not having read temp table (which writes disk). possible using staging table might still better since first query, update, might auto-create statistics benefit second query, insert, since query need either left join or where not exists.
  • merge along openrowset(bulk...), merge has "issues" wouldn't try this.

when getting data populate data grid, have pulled data, made list , mapped model, this: public list<person> getpeople() { var data = _db.person.tolist(); list<person> people = new list<person>(); foreach (var item in data) { person person = new person() { personid = item.personid, firstname = item.firstname, lastname = item.lastname }; people.add(person); } return people; } this works fine, in interest of writing less code discovered .select method , (what think is) anonymous type. have: public list<person> getpeople() { return _db.person.select(d => new person { personid = item.personid, firstname = item.firstname, lastname = item.lastname }).tolist(); } though not easy read, works fine too. there preference either way? ...

Listeners to visualise results of load test in JMeter -

i want run load test in non-gui mode , save results in .csv file. (i have not modified .properties files, standard information saved) i plan load file , visualise results jmeter’s listeners. which listeners suited purpose? should avoid @ cost, might cause me misinterpret information? (e.g. in view results tree response data empty have - - not saved this. however, there has in fact been response. if saw listener might think there hasn’t been one. since want avoid this, listeners have gain information needed .csv file.) i’d know both jmeter listeners plugins. if running test in non-ui mode ideally should disable listeners in script. use '-l' option store test results .jtl extension. can later open jtl file jmeter. aggregate report or summary report should summarize test results , response time , throughput. if want plot graphs see trends on test duration can use http://jmeter-plugins.org/#/ standard , lib set. i suggest following listeners: response ...
