10. Test DML
Create table:
–source MySQL
CREATE TABLE TCUSTMER
(
CUST_CODE VARCHAR(4) NOT NULL,
NAME VARCHAR(30),
CITY VARCHAR(20),
STATE CHAR(2),
PRIMARY KEY (CUST_CODE)
);
–target Oracle
CREATE TABLE tcustmer
(
cust_code VARCHAR2(4),
name VARCHAR2(30),
city VARCHAR2(20),
state CHAR(2),
PRIMARY KEY (cust_code)
USING INDEX
);
Test SQL:
INSERT INTO TCUSTMER
VALUES
(
‘Alex’,
‘Alex&Lina INC.’,
‘LA’,
‘CA’
);
INSERT INTO TCUSTMER
VALUES
(
‘JANE’,
‘ROCKY FLYER INC.’,
‘DENVER’,
‘CO’
);
INSERT INTO TCUSTMER
VALUES
(
‘WILL’,
‘BG SOFTWARE CO.’,
