I want to create a script to fill a database for testing. How would I set a string to be hashed and the inserted into the database?
I have:
INSERT INTO `loop`.`User`
(`userID`,
`firstName`,
`lastName`,
`email`,
`password`,
`userName`,
`bio`,
`spamCount`)
VALUES
('gZvTtlPtjGRqeMBaLji3HxoKB5EZCsNL',
'Joe',
'Smith',
'[email protected]',
SHA2('testgZvTtlPtjGRqeMBaLji3HxoKB5EZCsNL', 256),
'[email protected]',
"TEST BIO",
0);
How do I hash the string and INSERT in same statement?
You can insert a SELECT instead of VALUES to run a function on one of the inputs:
INSERT INTO `loop`.`User`
(`userID`,
`firstName`,
`lastName`,
`email`,
`password`,
`userName`,
`bio`,
`spamCount`)
SELECT
'gZvTtlPtjGRqeMBaLji3HxoKB5EZCsNL',
'Joe',
'Smith',
'[email protected]',
SHA2('testgZvTtlPtjGRqeMBaLji3HxoKB5EZCsNL', 256),
'[email protected]',
"TEST BIO",
0;
VALUES they have to be straight up values (strings, integers, etc.) rather than functions or subqueries that resolve to values. When using a SELECT statement, however, one is not constrained in this way.
If you already have the table filled by some content, you can alter it with the following :
ALTER TABLE `page` ADD COLUMN `hash` char(64) AS (SHA2(`content`, 256)) AFTER `content`
This solution will add hash column right after the content one, generates hash for existing and new records too without need to change your INSERT statement.
