Creating a table in SQL using Oracle 11G

Question

I am new to learning SQL and have been struggling to create a table for an assignment. These are the requirements:

Create a new table to track the Library location.

• LIBRARY (lib_id, lib_name, lib_address, lib_city, lib_state, lib_zip)

• LIB_ID is the library id – it is an auto generated number. (you should create a sequence number called lib_id_seq, start with 1001 and increment by 1.)

• LIB_ID is the primary key.
• LIB_NAME, LIB_ADDRESS, and LIB_CITY is between 1 and 35 characters.
• LIB_STATE is 2 characters – default to TX.
• LIB_ZIP is 5 numbers. Check for one of the following zip codes – 75081, 75080, 75082, 75079, 75078

And this is what I have written out so far:

CREATE TABLE LIBRARY
(
  LIB_ID INT(4),
  LIB_ADDRESS VARCHAR(35),
  LIB_CITY VARCHAR(35),
  LIB_STATE VARCHAR(2) DEFAULT ‘TX’,
  LIB_ZIP INT(5) CHECK (Frequency IN ('75078', ‘75079', '75080', '75081', ‘75082’))
  PRIMARY KEY(LIB_ID)
);

CREATE SEQUENCE LIB_ID_SEQ
START WITH 1001
INCREMENT BY 1;

I keep getting errors, but am not sure what I need to fix.

Answer 1

For oracle (Kid Tested unsure if SO approved)...

• use varchar2 instead of varchar
• use Number instead of int
• added constraint syntax (named them)
• adjusted apostrophe's (Removed) instead of whatever the heck you had in some of them :P (It's a numeric field shouldn't be using text apostrophes!)
• personally I wouldn't name a table library as that's a reserved word
• I woudln't use a numeric Zip code as we will never do math on a zipcode.

. .

CREATE TABLE LIBRARY (
LIB_ID Number(4),
LIB_ADDRESS VARCHAR2(35),
LIB_CITY VARCHAR2(35),
LIB_STATE VARCHAR2(2) DEFAULT 'TX',
LIB_ZIP NUMBER(5),
CONSTRAINT Lib_ZIP_CON CHECK (LIB_ZIP IN (75078, 75079, 75080, 75081, 75082)),
CONSTRAINT LIB_ID_PK PRIMARY KEY(LIB_ID)
);

CREATE SEQUENCE LIB_ID_SEQ
START WITH 1001
INCREMENT BY 1;

Answer 2

This works for SQL Server. You need to modify the syntax accordingly for the concerned db.

CREATE TABLE LIBRARY

(
LIB_ID INTEGER PRIMARY KEY,

LIB_ADDRESS VARCHAR(35),

LIB_CITY VARCHAR(35),

LIB_STATE VARCHAR(2) DEFAULT 'TX',

LIB_ZIP INTEGER, 

CHECK( LIB_ZIP IN ('75078', '75079', '75080', '75081', '75082') )

);


CREATE SEQUENCE LIB_ID_SEQ

START WITH 1001

INCREMENT BY 1;
