Which is better:search JTables or search Database tables?

Question

greetings all
i have UI With many jtables,every jtable reads data from it's own table in a MySQL database
and i want to make a search mechanism in a specific column in all the tables
and once item is found the row is highlighted.
i made it with two ways:
1-make for loop in each jtable and once item is found , current loop is exited and other loops are not entered
2-make connection with the database
and create several resultsets ,every resultset execute a select query on the desired item
and if one of the Resultsets returns data means item is found then i highlight it in the equivalent jtable.
i executed the two ways and felt no difference in the speed of finding item
but i want to know what is the best way of them or in general,as better design or in case of large applications?
thanks in advance

first_knight, you have no bloody idea what you're doing.
you're asking if it's better to search on the client or the server.
this suggests to me that the entire contents of the database are brought down to the client. this is usually a bad idea except for very small data sets. in that case, it doesn't matter where you do it.
if you have lots of data, it's best to let the database do it. first, it will actually have all the data. second, it's been optimized to do searches faster than any code you'll ever write.
either way, judging from your questions here you'll never get either one to work.
