Text adoption mail is often included in the term direct response mail, but by its very nature and objectives it really should be in a category of its own. With this type of mailing the publisher expects to receive exam copy requests and future orders for classroom use.
The PL/SQL WHILE Loop. The WHILE loop, also called a conditional loop, evaluates a condition before each loop executes, and if false, the loop is terminated. If the expression is false when the program reaches the WHILE loop, the loop code is jumped and never executed.Use a WHILE loop when the condition test is required at the start of the loop. The next example contains three WHILE loops.The last loop will never execute because the condition will never be true. The middle loop uses multiple condition tests, using the AND key word.se a WHILE loop when the condition test is required at the start of the loop. The next example contains three WHILE loops. The last loop will never execute because the condition will never be true. The middle loop uses multiple condition tests, using the AND key word.
Inside the FOR loop, the idx variable is the loop index. Once the FOR loop terminates, the loop index goes out of scope and the original idx variable is again in scope. PL/SQL procedure successfully completed. You can use the loop index inside the loop, but you can not change it.he PL/SQL FOR Loop. The FOR loop executes for a specified number of times, defined in the loop definition. Because the number of loops is specified, the overhead of checking a condition to exit is eliminated.
