using (-) dash in mysql table name
(2 answers)
Closed 9 months ago.
username:admintest
password:' or 1=1#
(and it works perfectly)
But here is the problem
username:a-dmintest
password:' or 1=1#
(and it doesnt work)
when the username have a dash it don't work
Why ?
Maybe you just dont have a user called "a-dmintest"
The dash is not a operator in SQL

I've a table like this,
values
-------------------
male,female
PHP 30
PHP (30)
PHP ($30),CSS ($20)
PHP {$30},CSS {$20}
PHP [$30],CSS [$20]
PHP (€30),CSS (20)
I've prepared the sql like this,
SELECT mytable.values FROM mytable WHERE mytable.values REGEXP '[[:<:]]PHP ($30)[[:>:]]'
It should match one row (4th), but it's not working.
It's also not working with
() / {} / [] or any types of symbols like $ / €
I want to mention here that,
MYSQL LIKE isn't the right thing for me I think, because it won't work if we want to match male.
REGEXP is working for PHP 30 here and it's working for only strings.
Could anyone please inform me what will be the best solution to match the exact word or sentence?
Thanks in advance.

I'm having an issue with a query I'm running on MySQL that contains some regex, here it is: SELECT * FROM dump WHERE Hours REGEXP '^\d{337}1{8}'
When I test my regex separately it's working fine, here's some sample data that it matches with:
000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000011111111111111111111111111111111111111111111111100000000000000000000000000000000000000000000000011111111111111111111111111111111111111111111111100000000000000000000000000000000000000000000000011111111111111111111111111111111111111111111111100000000000000000000000000000000000000000000000011111111111111111111111111111111111111111111111100000000000000000000000000000000000000000000000011111111111111111111111111111111111111111111111100000000000000000000000000000000000000000000000011111111111111111111111111111111111111111111111100000000

I want to create a table using this Syntax

But then as you can see, there's a red underline on "text".
I have tried using text.'tblemployee', 'text.tblemployee' , etc.
None of them worked.
Am I missing something here?
p.s : this is my first post ever, sorry if it is not really descriptive, Cheers.
Please replace the symbol apostrophe(') with the back quote(`)

Syntax error due to using a reserved word as a table or column name in MySQL
(1 answer)
Closed 7 years ago.
It makes no sense. I have a TINYINT field that is either 0 or 1 and I'm trying to set it like this:
UPDATE db_products SET return='1' WHERE product_id=342343434
But it tells me there's a mySQL syntax error. What am I doing wrong here? Is the problem that the field is called return? If so, how do I get around it without changing it?
In most cases, you can get around reserved word problems by enclosing with "ticks"; the quote-like thing that usually shares the ~ key.
UPDATE db_products SET `return`='1' WHERE product_id=342343434
