Find minimum and maximum values based on column with associative array
Hello,
I need to find out the minimum and maximum values based on specific column, and then print out the entire row with the max value.
I have tried this one:
and I only get
Note column 6 is the common field for keys of the associative array I was trying. The problem is with the min[$6], which is always set to 0 by default. Any help is greatly appreciated!
I'm at wits end with this issue and my troubleshooting leads me to believe it is a problem with the file formatting of the array referenced by my script:
awk -F, '{if (NR==FNR) {a=$4","$3","$2}\
else {print a "," $0}}' WBTSassignments1.txt RNCalarms.tmp

fbsql_fetch_array
FBSQL_FETCH_ARRAY(3) 1 FBSQL_FETCH_ARRAY(3)fbsql_fetch_array - Fetch a result row as an associative array, a numeric array, or bothSYNOPSIS
array fbsql_fetch_array (resource $result, [int $result_type])
DESCRIPTION fbsql_fetch_array(3) is a combination of fbsql_fetch_row(3) and fbsql_fetch_assoc(3).
An important thing to note is that using fbsql_fetch_array(3) is NOT significantly slower than using fbsql_fetch_row(3), while it provides
a significant added value.
PARAMETERS
o $
result -A result identifier returned by fbsql_query(3) or fbsql_db_query(3).
o $result_type
- A constant and can take the following values: FBSQL_ASSOC, FBSQL_NUM, or FBSQL_BOTH. When using FBSQL_BOTH, in addition to
storing the data in the numeric indices of the result array, it also stores the data in associative indices, using the field names
as keys.
RETURN VALUES
Returns an array that corresponds to the fetched row, or FALSE if there are no more rows.
If two or more columns of the result have the same field names, the last column will take precedence. To access the other column(s) of the
same name, you must the numeric index of the column or make an alias for the column.
select t1.f1 as foo t2.f1 as bar from t1, t2
EXAMPLES
Example #1
fbsql_fetch_array(3) example
<?php
fbsql_connect($host, $user, $password);
$result = fbsql_db_query("database", "select user_id, fullname from table");
while ($row = fbsql_fetch_array($result)) {
echo "user_id: " . $row["user_id"] . "<br />
";
echo "user_id: " . $row[0] . "<br />
";
echo "fullname: " . $row["fullname"] . "<br />
";
echo "fullname: " . $row[1] . "<br />
";
}
fbsql_free_result($result);
?>
