Question

I want to get or fetch maximum date from a table grouped by party_id.

To do this I tried:

$check = mysql_fetch_array(mysql_query("select max(fixed_date) as f from case_proceeding group by party_id where party_id='$row[party_id]'"));

After that, I want to print that maximum date like this:

echo $check['f'];

but it does not work. I think there is a mistake in the mysql_query.

Answer 1

try, GROUP BY (which should come after WHERE clause) isn’t needed here since you already filtered from WHERE

$check = mysql_fetch_array(mysql_query("select max(fixed_date) as f from case_proceeding where party_id='$row[$party_id]'"));

but your quesry is vulnerable with SQL Injection, please read the article below to protect against it
