sql server - Compare calling data from Stored Procedures and .NET 'Entity' objects -

-

i know what's best (fastest) way gain in performance (memory usage, cpu, ...) between these:

  1. you create .dbml or .edmx file call list of entities follows

    myentitiesdatacontext db = new myentitiesdatacontext(); var models = db.labels.tolist();

  2. you create stored procedure, drag/drop on .dbml / .edmx file call follows 

    myentitiesdatacontext db = new myentitiesdatacontext(); var models = db.listlabelprocedure();

this second way of coding further work because need develop stored procedures yourself.

ps: working big data. smallest table can register 10g. rows

can tell me best approach?

all depend on need datas... if need them .net server side think both approaches similar. if can process them sql server side stored procedure, retrieve result, stored procedure approach idea.

moreover think should carefull linq .tolist() because "load" datas sql server (network , memory usage), if have huge tables, impact asp.net server's memory, call stored procedure won't.

i hope bit

i use sonar plugin executes if activated in maven profile. sonar runs on every compile. the problem build fail other team members not have sonar application installed locally. pom.xml checked in team members same copy including sonar configuration, don't want them modify purpose of disabling sonar (they might inadvertently check modified copy in). please advise how configure maven (.m2/settings.xml) and/or pom.xml sonar feature can enabled/disabled local profile. here sonar configuration in each project's pom.xml: <plugin> <groupid>org.codehaus.mojo</groupid> <artifactid>sonar-maven-plugin</artifactid> <version>1.0</version> <executions> <execution> <id>make-sonar</id> <phase>compile</phase> <goals> <goal>sonar</goal> </goals> </execution> </executions> ...

python - TypeError: can only concatenate tuple (not "float") to tuple -

-
i'm new python, question might easy, anyway, patience: as trying call newton-raphson method calculate implied volatility in black-scholes formula call/put option pricing, first thing is, newton method in scipy.optimize seems calculate function's zeros, in black-scholes formula, want function's value option price, not zero. (i'm new here programming, i'm not sure techniques.) should write function things like: def f(sigma, price): return bsformula(s0,k,r,t,q,sigma) - price then, while calling newton method, takes args=() 1 parameter in function, write this: value = newton(bsprice2, 0.5, args=price) but error message: file "bs.py", line 36, in bsimpvol value = newton(bsprice2, 0.5, args=float(price)) file "/usr/lib/python2.7/dist-packages/scipy/optimize/zeros.py", line 143, in newton q0 = func(*((p0,) + args)) typeerror: can concatenate tuple (not "float") tuple could tell me why that? how fix it? apprecia...

java - What is the difference between String. and String.this. ? -

this question has answer here: meaning of .this , .class in java 2 answers i'll straight point. im still learning bit of syntax , want know difference between code is code a: public class buttonz extends jbutton{ public buttonz(){ settext(new string(string.valueof(i))); } } please ignore fact i undeclared, not lost. code b: public class buttonz extends jbutton{ public buttonz(){ settext(new string(string.this.charat(i))); } } what don't yet understand difference in typing string.this , string. i under assumption when use dot operator on class accessing it's static methods(and/or variables if they're not hidden). i have studied little bit , have concluded when using string. accessing string static methods.. when using string.this. i'm accessing methods class buttonz extendi...
