Question

I need to find the largest value from one particular column in a mysql table where the value of another column is equivalent to something. But, with the query that I’m using, I keep on getting a message that displays and SQL error. My query is aS follows:

SELECT MAX(message_id) AS top_message HAVING(child_id) = '".$message_id[$i]."'

Any suggestions?

You are also missing a table name:

SELECT MAX(message_id) AS top_message FROM tablename WHERE child_id = '".$message_id[$i]."'
