$query = "SELECT val FROM table WHERE id = 1"; mysql_query($query);
$ query =“SELECT val FROM table WHERE id = 1”;的mysql_query($查询);
This returns a single peice of data from the database. all the ways I know how to deal with this data are mysql_fetch_array() and mysql_fetch_assoc() is there a way to deal with 1 peice of data that doesn't involve pulling it into an array?
这将从数据库返回一个数据。我知道如何处理这些数据的所有方法是mysql_fetch_array()和mysql_fetch_assoc()有没有办法处理1个不涉及将其拉入数组的数据?
3 个解决方案
#1
There is mysql_fetch_field
which appears to do what you want.
有mysql_fetch_field似乎可以做你想要的。
mysql_fetch_field(0,0);
#2
Many wrapper libraries offer this, for example, with ADODb, it's simple
许多包装器库提供了这种功能,例如ADODb,它很简单
$value=$db->GetOne("select val from table where id=1");
It's not hard to roll your own either.
也不难推出自己的产品。
#3
You can use mysql_result()
like this;
你可以像这样使用mysql_result();
mysql_result(mysql_query($query), 0, 0);
The second parameter selects the row, and the third is the field number.
第二个参数选择行,第三个参数是字段编号。
