    <p>So i'm having this problem.</p> <p>I have two tables (Oracle), one is called Destination and the other one Reserve. Reserve has a foreign key to the id of Destination (Because on reserve has one destination). And reserve tuples means all the reserves that all the users have done. I need a way to check the top 3 most visited Destinations (based on the foreign key in the table Reserve).</p> <p>How can I do that with SQL in Oracle. I know that I need to search within the Reserve tables for the 3 most repeated Destinations ID's, and later join that with the Destination table to get the details of the top 3 destinations.</p> <p>Any help is valid. Thank you very much.</p> <p>SCHEMA:</p> <pre><code>-------------------------------------------------------- -- File created - martes-septiembre-15-2009 -------------------------------------------------------- -------------------------------------------------------- -- DDL for Table DESTINO -------------------------------------------------------- CREATE TABLE "S2501A29"."DESTINO" ( "PK_ID_DESTINO" NUMBER(10,0), "FK_COD_UBICACION_GEOGRAFICA" NUMBER(10,0), "NOMBRE" VARCHAR2(10), "FOTO" VARCHAR2(30), "DESCRIPCION" VARCHAR2(50) ) ; -------------------------------------------------------- -- DDL for Table LUGAR_ESTADIA -------------------------------------------------------- CREATE TABLE "S2501A29"."LUGAR_ESTADIA" ( "PK_ID_ESTADIA" NUMBER(10,0), "NOMBRE" VARCHAR2(10), "TIPO" VARCHAR2(10), "DESCRIPCION" VARCHAR2(50), "COSTO_SERVICIOS" NUMBER, "DESCRIPCION_ALOJAMIENTO" VARCHAR2(100), "DESCRIPCION_ALIMENTACION" VARCHAR2(100) ) ; -------------------------------------------------------- -- DDL for Table OPCION_TRANSPORTE -------------------------------------------------------- CREATE TABLE "S2501A29"."OPCION_TRANSPORTE" ( "PK_ID_VIAJE" NUMBER(10,0), "MEDIO_TRANSPORTE" VARCHAR2(10), "RESPONSABLE" VARCHAR2(10), "CIUDAD_ORIGEN" VARCHAR2(10), "CIUDAD_DESTINO" VARCHAR2(10), "COSTO" NUMBER ) ; -------------------------------------------------------- -- DDL for Table RESERVA -------------------------------------------------------- CREATE TABLE "S2501A29"."RESERVA" ( "PK_ID_RESERVA" NUMBER(10,0), "FK_COD_DESTINO" NUMBER(10,0), "FK_COD_ESTADIA" NUMBER(10,0), "FK_COD_VIAJE" NUMBER(10,0), "TARJETA_CREDITO" VARCHAR2(12), "FECHA_SALIDA" DATE, "FECHA_REGRESO" DATE, "NOMBRE_USUARIO" VARCHAR2(50) ) ; -------------------------------------------------------- -- DDL for Table UBICACION_GEOGRAFICA -------------------------------------------------------- CREATE TABLE "S2501A29"."UBICACION_GEOGRAFICA" ( "PK_ID_UBICACION" NUMBER(10,0), "CIUDAD" VARCHAR2(10), "PAIS" VARCHAR2(10), "CONTINENTE" VARCHAR2(10) ) ; </code></pre> <p>Just a note:</p> <p>RESERVE is Reserva DESTINATION is Destino </p> <p>Because the DB is in spanish.

    1. COThis would be easier if you gave us an exact schema of the DB. Like the CREATE TABLE statements that would duplicate your setup.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
