A Simple Information Model PHYSICAL TABLES PAT PAT_CLNCIAN_ASSOC PAT_ID INT PAT_ID INT CLNCIAN_ID INT PAT_FNM VARCHAR(20) PAT_LNM VARCHAR(35) PAT_CLNCIAN_IDX INT ASSOC_BEGIN_DT DATE ASSOC_END_DT DATE ASSOC_CAT_CD TINYINT CLNCIAN CLNCIAN_ID INT CLNCIAN_NM VARCHAR(250)

SQL Commands CREATE TABLE PAT ( PAT_ID INT NOT NULL PRIMARY KEY, PAT_FM VARCHAR(20), PAT_LNM VARCHAR(35) ) TYPE=INNODB; CREATE TABLE CLNCIAN( CLNCIAN_ID INT NOT NULL PRIMARY KEY, CLNCIAN_NM VARCHAR(250) CREATE TABLE PAT_CLNCIAN_ASSOC( CLNCIAN_ID INT NOT NULL, PAT_ID INT NOT NULL, PAT_CLNCIAN_IDX INT NOT NULL, ASSOC_BEGIN_DT DATE, ASSOC_END_DT DATE, ASSOC_CAT_CD TINYINT NOT NULL, INDEX(CLNCIAN_ID), INDEX(PAT_ID), PRIMARY KEY(CLNCIAN_ID, PAT_ID, PAT_CLNCIAN_IDX), FOREIGN KEY (CLNCIAN_ID) REFERENCES CLNCIAN(CLNCIAN_ID), FOREIGN KEY (PAT_ID) REFERENCES PAT(PAT_ID)

Verifying the Tables

Loading Data into PAT Table INSERT INTO PAT(PAT_ID,PAT_FNM,PAT_LNM) VALUES (45671,'JOHN','DOE'), (45672,'JENNY','DOE'), (45673,'CINDY','FINNEGAN'); INSERT INTO PAT(PAT_LNM,PAT_FNM,PAT_ID) VALUES ('MARTINEZ','MANUEL',45674), ('VALLARES','MARGARITA',45675);

Loading Data into CLNCIAN Table INSERT INTO CLNCIAN(CLNCIAN_ID,CLNCIAN_NM) VALUES (8998,'DR. FERNANDO DE LA ROSA'), (8999,'DR. DIETLINDE WEINSTEIN'), (9000,'DR. PIERO LUIGI DELLA MIRANDOLA');

Loading Data into PAT_CLNCIAN_ASSOC Table INSERT INTO PAT_CLNCIAN_ASSOC(CLNCIAN_ID, PAT_ID, PAT_CLNCIAN_IDX, ASSOC_BEGIN_DT, ASSOC_END_DT, ASSOC_CAT_CD) VALUES (9000,45671,1,'2001-02-19','2003-11-21',3), (9000,45671,2,'2004-05-01','2005-01-31',1), (8998,45671,1,'2003-11-21','2004-04-30',3), (8999,45672,1,'1999-01-01','1999-12-31',2), (8998,45674,1,'2001-09-13','2001-12-31',2), (8999,45673,1,'1998-11-08','2000-07-24',1), (8998,45675,1,'1997-03-01','',3);

Referential Integrity There is no record in the CLNCIAN table with CLNCIAN_ID = 9005

SELECT Statement

SELECT {fields} Statement

SELECT DISTINCT Statement

SELECT COUNT Statement

JOINS SELECT PAT_FNM, PAT_LNM, CLNCIAN_NM,ASSOC_BEGIN_DT FROM PAT, CLNCIAN, PAT_CLNCIAN_ASSOC WHERE PAT.PAT_ID = PAT_CLNCIAN_ASSOC.PAT_ID AND CLNCIAN.CLNCIAN_ID = PAT_CLNCIAN_ASSOC.CLNCIAN_ID AND PAT.PAT_LNM = 'DOE';
