$result = mysql_query("SELECT * FROM register where name= ‘lakhan’ ") or die(mysql_error());
and when running the php file it shows:
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 '‘lakhan’'
I am using MySql Server 5.5 AND INSTEAD OF = sign i have used LIKE also in query then too error is coming.Please help me to resolve it
Use single quotes arround the value:
$result = mysql_query("SELECT * FROM register where name= 'lakhan' ") or die(mysql_error());
Do not longer use the deprecated mysql_* API. Use mysqli_* or PDOwith prepared statements.

I have problem. in my database, I have a column email. When I make SQL query I get following error:
You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near '#gmail.com)' at line 1
This is my code:
$sql = "SELECT ID_Dijak from dijak WHERE (Email=".$mejl.")";
If I try to do query in php my admin it works if I put ' ' between my email, but how to do it in php? Thank you.
I'm sorry I made a mistake earlier... I tested this way and it should now work
$sql='SELECT ID_Dijak from dijak WHERE (Email = "' . $mejl . '")';
take datatype varchar() for email
I would suggest using a prepared statement in PHP, also to prevent injection attacks.
$stmt = $dbc->prepare("SELECT ID_Dijak from dijak WHERE Email=?");
$stmt->bind_param("s", $mejl);
$stmt->execute();

I'm getting a syntax error with this block of code, and I have no idea why. Here is the specific error itself:
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 'match ORDER BY id DESC' at line 1
Here is the PHP code block:
$sql = "SELECT * FROM match ORDER BY id DESC";
$res = mysqli_query($dbCon, $sql);
MATCH is a reserved keyword in mysql: https://dev.mysql.com/doc/refman/5.0/en/keywords.html
To make your code working change your query to:
$sql = "SELECT * FROM `match` ORDER BY id DESC";

I'm trying to update a value in my table, but i have a syntax-error and i can't find the error.
This is my php code:
$data = new MysqlClass();
$data->connect();
$result_sql = $data->query("UPDATE iscrizioni SET '".$matricola."' = 'si' WHERE 'COD'=".$cod);
it returns me:
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 ''805710' = 'si' WHERE 'COD'=1' at line 1
Have you any idea where the error is?
Thank you very much!
You are using column's names as strings, use ` instead of '. Or don't use it at all.
$result_sql = $data->query("UPDATE `iscrizioni` SET `".$matricola."` = 'si' WHERE `COD` = ".$cod);

I can not find out why this is not working.....
i keep getting this message
Query failed: 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 ''laketaho_benny'.'tblPictures' SET 'caption' = 'uuuuuuuuuupppp' WHERE 'tblPic' at line 1
and this is my code
$sql = "UPDATE `laketaho_benny`.`tblPictures` SET `caption` = `$caption` WHERE `tblPictures`.`pictureID` =$pictureID;";
Single quotes are for strings. You're thinking of backquotes ( ` ).

This is where I think it´s the problem...
$sql1 = "SELECT `puntos_globales`, '$juego'
FROM `lista_jugadores` WHERE `id_jugador`='$noTop'";
This is the error message:
Error:
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 "blackOps2'='1' WHERE `id_jugador` = '10" at line 1
$juego .. is a php variable that holds the column name; in this case blackOps2. I don´t know why in the error says blackOps2'='1'??
from the error it seems you didnt provide the true query and it looks you have two where clause
blackOps2='1' WHERE `id_jugador` = '10"
try do it like that
WHERE `id_jugador` = '10' AND blackOps2='1'
