sql query number vs string

[ggalan]

when i update a table like this, it worls

UPDATE tableName SET itemID=523 WHERE descript_1 LIKE 'nameOfItem';

but when i update it as a string, it doesnt work

UPDATE tableName SET differentItemID='someString' WHERE descript_1 LIKE 'nameOfItem';

what is going on?

[fastsol1]

What is the string you are trying to update? You can always add

or die(mysql_error()) 

to the end of your query and that will give you an error if the query is failing due to a snytax error in the string or otherwise.

Is that column set to bit, int, float, or some other only numerical input?

fastols solution may give more results assuming you are using mysql, if not we will need to know what db you are using and what the column is set as.

[ggalan]

it was set to "varchar(20)"

And did you get anything from mysql_error()? Assuming you're using MySQL...

If there's no error, what's it updating that field with?

[ggalan]

#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'differentItemID='someString' WHERE descript_1 LIKE 'nameOfItem'' at line 1

Try using backticks for the column name:

UPDATE tableName SET `differentItemID`= 'someString' WHERE descript_1 LIKE 'nameOfItem';

I can't imagine that this would cause the problem, are you sure the code above is exactly what's going into the query? (minus the backticks).

Try echoing the SQL out just before you execute it.

From what you've posted, you should be getting an error along the lines of:

"SQL Error (1146): Table 'databaseName.tableName' doesn't exist".

(I executed the above query through HeidiSQL)

the backticks solved it! weird
i always thought that ` was the same as '
how do i get those backticks from my keyboard?

[Schmoopy]

Not sure what keyboard you have, but on mine (American English), the backtick is to the left of the "1" key. Should have like 3 symbols on it.

If you're not using this type of keyboard, then see if anyone else knows where it is.

[ggalan]

got it `, lol
but back to the original question, why would i need those backticks for the sql query to work?
