But There is some performance issue by jquery, so Javascript is the best solution for Hide and show any element on a web page. Sometimes JQuery isn't necessary; if this is the only thing you need to do on a page, the overhead of loading the library far outweighs the need to write concise JavaScript. It seems that hide() , show() and jquery visibility methods in general are not a good option in terms of performance.

This is very common problem in huge database to handle the duplicate data. Tables or result sets sometimes contain duplicate records. Sometimes, it is allowed but sometimes it is required to stop duplicate records. Sometimes, it is required to identify duplicate records and remove them from the table. This chapter will describe how to prevent duplicate records occurring in a table and how to remove already existing duplicate records. Check Duplicate data in table SELECT `col_name`, COUNT(*) as `record_find` FROM table GROUP BY col_name HAVING `record_find` > 1; Above query result will show the column name and number of time of record find in database table. Delete all duplicate records 1) If you want to keep the row with the lowest id value: DELETE n1 FROM names n1, names n2 WHERE n1.id > n2.id AND n1.name = n2.name 2) If you want to keep the row with the highest id value: DELETE n1 FROM names n1, names n2 WHERE n1.id < n2.id AND n1.name = n2.name I used this method in MySQL...

The words are not opposed to each other but rather describes two possible aspects of a subroutine. An attempt to define the words follows: Subroutine: A set of instructions that can be used several times in the same program. Function: A subroutine that returns a value. Derived from functions in mathematics. Method: A subroutine that belongs to an object or a class. Could be a function. Method is actually a function used in the context of a class/object. When you create a function outside of a class/object, you can call it a function but when you create a function inside a class, you can call it a method . class foo { public function bar (){ // a method ........ } } function bar (){ // a function not part of an object } So an object can have methods (functions) and properties (variables).
