CREATE TABLE JOB_TEMP (
JOB_ID VARCHAR2(10 BYTE) NOT NULL,
JOB_TITLE VARCHAR2(35 BYTE) NOT NULL,
MIN_SALARY NUMBER(6,0),
MAX_SALARY NUMBER(6,0),
PRIMARY KEY (JOB_ID)
);
ALTER TABLE JOB_TEMP
ADD JOB_CATEGORY VARCHAR2(255);
INSERT INTO JOB_TEMP(JOB_ID, JOB_TITLE, MIN_SALARY, MAX_SALARY, JOB_CATEGORY)
