Returns the time offset relative to the time the query executes. Operations that use date and time functions Produces a table with the distinct combination of the provided columns of the input table Use to test a queryĪdds a condition statement, similar to if/then/elseif in other systems.Ĭase(predicate_1, then_1, predicate_2, then_2, predicate_3, then_3, else) Searches all columns in the table for the value ![]() Has: Looks for a specific word (better performance) Operator/Functionįind relevant data by filtering or searching Look at the syntax and the example below to see how the PHP Switch statement works.This article shows you a list of functions and their descriptions to help get you started using Kusto Query Language. So when you have to compare the same variable for different values, and each value is associated with a different set of code, then use the Switch statement. When PHP Switch case checks the condition then it jumps to the appropriate case, skipping all other cases before that, and executes it. PHP Switch Case uses 'case', each case has a different set of instructions associated with it, written by the programmer. But if we use PHP Switch statement then only one condition will be checked and that's it. If the variable has 9, then the if.elseif statement will have to compare all the 9 'if' conditions to get to a result and print 'Nine'. So, one approach is to use the if.elseif statement, but it will increase the number of comparisons, that may slow down the program. And according to the value in the variable, the program has to print the number in words, like, 1 in One, 2 in Two, and so on till 9. Suppose there is a variable whose value will decide a certain kind of action, let's say the variable holds a number from 1 to 9. elseif statement would be a lengthy approach, so instead of that PHP Switch case can be used. It is used in a condition where using the if. PHP Switch Case : PHP Switch statement is very similar to a series of if.elseif statements but with a slight difference. ![]()
