What is meant by NULL value in MySQL

Posted by Jaisal Mishra 7 years, 1 month ago

CBSE > Class 12 > Informatics Practices

1 answers

Aryan Rai 7 years, 1 month ago

Null value is a value which means that the data is not available at that moment but later on it could be assigned any value. It should not be taken as 0 . There is a difference b/w the two as anything operated with 0 will give value as it is in Mathematics i.e 5+0=5 But it is not the case with NULL as anything operated with NULL gives the value NULL. e.g. 5+NULL will give NULL. It is applicable to any operations like (-,×,÷) .

1Thank You

Aryan Rai 7 years, 1 month ago

Button group is a property of radio button through which selection of radio button is restricted to one. e.g if we only select radio button for choosing gender, it would act like a checkbox i.e multiple selections will be done and hece we will end up choosing male and female gender for the same person. So button group is selected through which we can select only one gender out of two for a particular person. It should be noted that button group is not displayed while designing a GUI . It is hidden. And also only one button group is selected for as many as radio buttons. And the code for clearing a button group is - buttongroup.clearSelection ();
