Why would you open a server if you don't know the basics?
Easy way : Open the SK_Silk table from your account database.
Another method :
PHP Code:
USE
SRO_VT_ACCOUNT -- or however your account database is called
SELECT silk_own, silk_gift, silk_point FROM SK_Silk WHERE JID like '%'
Then, if you want to simply find the JID :
PHP Code:
USE
SRO_VT_ACCOUNT -- or however your account database is called
SELECT JID FROM SK_Silk WHERE silk_own like '%' -- % is the amount, silk_own can be replaced with silk_gift or silk_point
Like, seriously, I don't even know SQL and I'm able to do it.
