Hi ,
your query should be like this :

update cc_dailylog set campaign='Aircel' where username in ('','5101','5102','5103');

you need to modify your for loop to add single quote.

hello,
I have design a small GUI for login with Ok and Exit button. And on successful login i check for the updating the database. So when i'm doing this update i'm calling a Frame with progressbar and an ICON if all the data is updated then this frame is disposed and i'm calling another Frame.
login is diffrent class with it's Componenets and updating database is another class with no GUI componenets and Progressbar is different class.

So the problem is i'm not able to display the progress bar class components.It's showing blank frame with no components.If i write main Progress bar it show's every component.

Thank you,

i have frame size set to (750,415) and used pack()so that all the componenets are displayed and i have added an WindowStateChaged Listener to see frame has been resize. After the window state change then i tooked the size of the frame ie Dimension size=frame.getSize()/super.getSize(); then i set that size to panel size. panel.setSize(size); then revaildate()/repaint(); i have used but the size of panel is not getting set to Frame size so what is the problem and how to solve it.

Need help,
i have opened a file using RandomAccessFile in readmode and i have saved file length when file was first read, now the file is updated i.e. new lines are added to file which are written line by line . Now i want to go to updated data i.e. to new lines added to file without reading the file from first but to start with last offset. I have tried using file.seek(prevoius stored file length) but it skips few character data starting of the newlines added into the file. So i need help to go to newline after the last file length.
