SQLite Regarding queries

I have created a table in SQLite database with following statement.

i.e. static final String DATABASE_CREATE = "create table " + "TEST" + "( " + "ID" + " integer primary key autoincrement," + " UID text, FULLNAME text, GENDER integer, MSTATUS integer, MOBILE text, AGE text );";

with this statement, I can able to insert data but I want to design a function that will accept the mobile no. and return the UID.
