conditional-statements

I have the data in the follow way: ITEM LOCATION UNIT RETAIL QUANTITY 100 KS 10 -10 200 KS 20 30 I want the sum of positive quantities (quantity > 0) and sum of negative quantities (quantity < 0). How do I get those column sum based on condition? You can use SUM(CASE ... ) : SELECT item, location, SUM(CASE WHEN quantity > 0 THEN quantity ELSE 0 END) AS positive_sum, SUM(CASE WHEN quantity < 0 THEN quantity ELSE 0 END) AS negative_sum FROM your_table GROUP BY item, location; LiveDemo You can use GREATEST and LEAST in conjunction with the SUM function: SQL Fiddle Oracle 11g R2 Schema Setup :

Is there any difference between writing multiple if statements and if-else-if statements ? When I tried to write a program with multiple if statements, It did not give the expected results, But it worked with if-else-if . The conditions were mutually exclusive. When you write multiple if statements, it's possible that more than one of them will be evaluated to true, since the statements are independent of each other. When you write a single if else-if else-if ... else statement, only one condition can be evaluated to true (once the first condition that evaluates to true is found, the next else

Why ng-if doesn't work for me in this example but ng-show does JSFiddle : <div ng-if="false">text</div> <div ng-show="false">text2</div> and how to fix that? ngIf is a new directive added in v1.1.5. JSFiddle has you on 1.1.1. 来源： https://stackoverflow.com/questions/16777152/angularjs-ng-if-boolean-condition-doesnt-work

I need suggestion for the right approach to apply conditions in Java. I have 100 conditions based on which I have to change value of a String variable that would be displayed to the user. an example condition: a<5 && (b>0 && c>8) && d>9 || x!=4 More conditions are there but variables are the same more or less. I am doing this right now: if(condition1) else if(condition2) else if(condition3) ... A switch case alternative would obviously be there nested within if-else's i.e. if(condition1) switch(x) { case y: blah-blah } else if(condition2) switch(x) { case y: blah-blah } else if(condition3) ...

I have the following code: <Import Project="C:\Program%20Files%20(x86)\MSBuild\ExtensionPack\4.0.13.0\x64\MSBuild.ExtensionPack.tasks" /> <PropertyGroup> <Workspace></Workspace> <SolutionName></SolutionName> <TargetEnv></TargetEnv> <DeployPath></DeployPath> <TargetBranch></TargetBranch> <BuildNumber></BuildNumber> <Revision></Revision> </PropertyGroup> <Target Name="assinfo"> <Choose> <When Condition=" '$(TargetEnv)'=='development' "> <PropertyGroup> <Revision>1</Revision> </PropertyGroup> </When> </Choose> Msbuild shows this error: C:\workspace\BuildScripts\buildTEST.proj(20,3): error MSB4067

I would like to include an "AND" condition for one of the conditions I have in my COUNTIFS clause. Something like this: =COUNTIFS(A1:A196;{"Yes"or "NO"};J1:J196;"Agree") So, it should return the number of rows where: (A1:A196 is either "yes" or "no") AND (J1:j196 is "agree") You could just add a few COUNTIF statements together: =COUNTIF(A1:A196,"yes")+COUNTIF(A1:A196,"no")+COUNTIF(J1:J196,"agree") This will give you the result you need. EDIT Sorry, misread the question. Nicholas is right that the above will double count. I wasn't thinking of the AND condition the right way. Here's an
