How to select multiple rows from mysql with one query and use them in php
Use repeated calls to mysql_fetch_assoc. It's documented right in the PHP manual.
http://php.net/manual/function.mysql-fetch-assoc.php
// While a row of data exists, put that row in $row as an associative array
// Note: If you're expecting just one row, no need to use a loop
// Note: If you put extract($row); inside the following loop, you'll
// then create $userid, $fullname, and $userstatus
while ($row = mysql_fetch_assoc($result)) {
echo $row["userid"];
echo $row["fullname"];
echo $row["userstatus"];
}
If you need to, you can use this to build up a multidimensional array for consumption in other parts of your script.
How to select multiple rows from the same table only using one query?
A couple of ways:
Using between:
SELECT def_conteudo FROM conteudo WHERE nro_conteudo BETWEEN 101 AND 104;
This fetches every row with an ID between those two number. If I remember correctly, the lower end is inclusive and the higher end is exclusive.
Alternatively, if they are not consecutive:
SELECT def_conteudo FROM conteudo WHERE nro_conteudo IN (101, 102, 103, 104);
This will fetch the ID's in the list.
MYSQL - Select multiple rows in one query
You can retrieve the highest id of the claimid using group by.
$query = "SELECT max(Id) as Id,claimId FROM statusTable ";
$query .= "WHERE (`chaseStatus` = 'Open') ";
$query .= "GROUP BY claimId";
THis should result in the following table
Id claimId
5 CL001
6 CL003
Here's a SQL Fiddle: http://sqlfiddle.com/#!2/b000e/1
mysql query select multiple rows where column value is same
$query = "SELECT * FROM `table` WHERE `Column_2` = 'value1' ";
$res = mysql_query($query);
if(mysql_num_rows($res)!=0) {
while($rowData = mysql_fetch_array($res)) {
var_dump($rowData);
}
}
- Use mysql_num_rows to count number of results.
- Use mysql_fetch_array or mysql_fetch_assoc to fetch data.
