do reply what is the problem.... as in my database these are the tabe that i am using....
CREATE TABLE PHOTO(
ID NUMBER NOT NULL PRIMARY KEY ,
Name VARCHAR2(10),
X DOUBLE PRECISION,
Y DOUBLE PRECISION,
Tags VARCHAR2(40)
);
CREATE TABLE RESTAURANT(
ID_RESTAURANT NUMBER NOT NULL PRIMARY KEY ,
Name_RESTAURANT VARCHAR2(10),
X_RESTAURANT DOUBLE PRECISION,
Y_RESTAURANT DOUBLE PRECISION,
FOODTYPE VARCHAR2(20),
PHONENO NUMBER
