This is my code currently:
create table client (
client_id int,
birth_number int,
district_id int
Primary Key (district_id)
);
truncate client;
load data local infile 'C:\\Users\\james\\Desktop\\Wecloud_Data_Bootcamp\\bank_loan\\client.asc'
into table client
fields terminated by ';'
lines terminated by '\n'
ignore 1 lines
(client_id, @birth_number, district_id)
SET birth_number = REPLACE(@birth_number, '"','');
-- Check the table
select * from client;
this is the current table
What I need to do is split the birth_number column into two columns, which are birthday date and gender respectively. The instructions are below, probably integer manipulation is needed, how do I do so?
Please assist me.i tried replicating this query using Microsoft SQL. i tried this below query but got "Argument data type nvarchar is invalid for argument 1 of format function." as error message. see my code below:
Try this:
SELECT
DATE_FORMAT(CONCAT(SUBSTR(birth_number, 1, 2),
IF(SUBSTR(birth_number, 3, 2) > 50,
SUBSTR(birth_number, 3, 2) - 50, SUBSTR(birth_number, 3, 2)),
SUBSTR(birth_number, 5, 2)),
'%Y-%M-%d'
) AS `date`,
IF(SUBSTR(birth_number, 3, 2) > 50, 'Female', 'Male') AS Gender
FROM `client`
Change the format of the date as per your requirement.
