When to use single quotes, double quotes, and backticks in MySQL

I want to create a table using this Syntax
MySQL
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(`)

This line of code is no working, and I cannot for the life of me figure out what is wrong with it.
INSERT INTO teacher (email,password,admin) VALUES (deborah68#example.org,d%6AsQPq7y,1);
this wont run and says the error is near the end of the line
any help is appreciated, the schema is called at3
Why are you not enclosing the string/char data in single quotes ? Assuming they are of datatype varchar, you simply enclose them in single quotes and the command will work.
INSERT INTO teacher (email,password,admin) VALUES ('deborah68#example.org','d%6AsQPq7y',1)
Assuming your email and password are datatype of varchar, try putting '' between the values, or better you can use parameterized value if it's any backend code, try:
INSERT INTO teacher (email,password,admin) VALUES ('deborah68#example.org','d%6AsQPq7y',1);

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.

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

How can I find non-ASCII characters in MySQL?
(10 answers)
Closed 9 years ago.
I'm trying to find all non-asci characters I have in my DB in a specific table and column. In that column are stored Html description, and in some of them I've exotic or non-existing characters (for example: Hà¶ganà¤s ).
I'm triyng to match them with this query:
SELECT * FROM project_version WHERE description REGEXP '[^()\x00-\xFF\,\.-\<\>="\' /:;&=]'
But I think I'm missing something, cause it returns all of my records. Does anyone any advice?
Thanks in advance
Try moving hyphen to start or end otherwise it needs to be escaped also ^ will be treated as literal ^ in character class:
SELECT * FROM project_version WHERE description REGEXP '[()\x00-\x7F,.<>="\' /:;&=-]'
