A:B:C:D:The answer is a. The "Select @avgPrice =avg (bookprice) from book" statement in the topic calls the AVG () function to get the average price of the books, whereas option C and option D refer to the highest price, so options C and D are wrong. In the IF statement, use the conditional expression "(@avgPrice >80)" To determine whether the value of the local variable @avgprice is greater than 80. If it is greater than 80, the query results are sorted in descending order by the DESC keyword i

One of the great challenges we all face when writing unit tests is the dependency of modules on other components. Spending a lot of time and effort to configure a dependent component environment is a thankless task. Using mock is an efficient way to replace other components to continue our unit test build process. Next I'll show you an example of using a mock technique. Here I have a data access layer (DAL)

default branch, which must be the last branch of a switch statement. (3) default is executed when no case statement is equal to the value of the variable. The default branch does not require a break statement.Break is used to interrupt the loop statement, and continue is used to continue the loop. Breake break out of the loop body, continue continue the next loop, but the statement after continue is not running. Continue can only be used in loop statements, and break may be used in other branch
