Missing Right parenthesis error? - sql

Question

I'm trying to create a table in sqldeveloper however I keep getting a missing right parenthesis error when there are no missing right parenthises. Any fixes for this or am i just trying to create a table the wrong way?
CREATE TABLE Patient_T1(
PATIENT_ID INT(100) NOT NULL,
FIRST_NAME VARCHAR(20) NOT NULL,
LAST_NAME VARCHAR(30) NOT NULL,
DOB CHAR(10) NOT NULL,
P_STREET_ADRESS VARCHAR(50) NOT NULL,
PATIENT_CITY VARCHAR(30) NOT NULL,
PATIENT_STATE CHAR(2) NOT NULL,
PATIENT_ZIP CHAR(5) NOT NULL,
PATIENT_PHONE CHAR(12) NOT NULL,
PATIENT_ROOM INT(1000) NOT NULL,
CONSTRAINT PATIENT_PK PRIMARY KEY(PATIENT_ID));

Answer 1

Not sure why Oracle gives that error message instead of something more helpful, but the cause is the precision applied to INT, switch from INT(100) and INT(1000) to just INT:
CREATE TABLE Patient_T1(
PATIENT_ID INT NOT NULL,
FIRST_NAME VARCHAR(20) NOT NULL,
LAST_NAME VARCHAR(30) NOT NULL,
DOB CHAR(10) NOT NULL,
P_STREET_ADRESS VARCHAR(50) NOT NULL,
PATIENT_CITY VARCHAR(30) NOT NULL,
PATIENT_STATE CHAR(2) NOT NULL,
PATIENT_ZIP CHAR(5) NOT NULL,
PATIENT_PHONE CHAR(12) NOT NULL,
PATIENT_ROOM INT NOT NULL,
CONSTRAINT PATIENT_PK PRIMARY KEY(PATIENT_ID));

There are multiple issues with your table DDL:
INT(100) - In Oracle, an INTEGER is an ANSI SQL data type which refers to numeric values which have only an integer portion and no floating point or decimal part. That is, an INTEGER will only store whole numbers ONLY.
VARCHAR(20) - Oracle strongly recommends to use VARCHAR2.
From documentation,
VARCHAR Datatype
The VARCHAR datatype is synonymous with the VARCHAR2 datatype. To
avoid possible changes in behavior, always use the VARCHAR2 datatype
to store variable-length character strings.
CHAR(10) - better use VARCHAR2 as CHAR is blank-padded to the fixed length. That's a wastage of storage.
From documentation,
CHAR Datatype
The CHAR datatype stores fixed-length character strings. If you give a
shorter value, then the value is blank-padded to the fixed length.
Only the issue# 1 would throw an error, anyway fixing all the above issues would let you create the table.
For example,
SQL> CREATE TABLE Patient_T1
2 (
3 PATIENT_ID NUMBER NOT NULL,
4 FIRST_NAME VARCHAR2(20) NOT NULL,
5 LAST_NAME VARCHAR2(30) NOT NULL,
6 DOB DATE NOT NULL,
7 P_STREET_ADRESS VARCHAR2(50) NOT NULL,
8 PATIENT_CITY VARCHAR2(30) NOT NULL,
9 PATIENT_STATE VARCHAR2(2) NOT NULL,
10 PATIENT_ZIP VARCHAR2(5) NOT NULL,
11 PATIENT_PHONE VARCHAR2(12) NOT NULL,
12 PATIENT_ROOM NUMBER NOT NULL,
13 CONSTRAINT PATIENT_PK PRIMARY KEY(PATIENT_ID)
14 );
Table created.
