简单的MySQL查询无法在PHP中工作

Question

Suddenly the sql query is not woking in add table.

It works in other table though. Is there any wrong in code?

$sql="select index,name from add Limit 0,10";
$result=mysql_query($sql);
    while($row=mysql_fetch_assoc($result))
    { 
echo $row['name'];
}

The index name is filled with random data.

Answer 1

add is a reserved word in MySQL. You have to quote it.

Answer 2

Try this:

$sql="select index,name from `add` Limit 0,10";
$result=mysql_query($sql);
while($row=mysql_fetch_assoc($result))
{ 
   echo $row['name'];
}

Backticks around the table name. 'add' is a keyword

Answer 3

$sql="select index,name from add Limit 0,10";

add is a reserved keyword in MySQL. So is index . Escape these two using backticks and it shall work:

$sql="select `index`,name from `add` Limit 0,10";

Answer 4

$sql="select `index`,`name` from `add` Limit 0,10";
$result=mysql_query($sql);
    while($row=mysql_fetch_assoc($result))
    { 
echo $row['name'];
}
