Bug compare file columns

I need help in file comparision.

I have two files in below format:
FILE_A:
-------
COL1 COL2 COL3 COL4 COL5

FILE_B:
-------
COL1A COL1B COL1C COL1D COL1E

i want to compare for a for each row in FILE_A and FILE_B
COL1 of FILE_A with COL1B of FILE_B
COL3 of FILE_A with COL1E of FILE_B
COL5 of FILE_A with COL1C of FILE_B

and in case they are matching, print the column values COL1 COL2 COL3 from FILE_A into FILE_OK,
and if they do not match then print them into FILE_ERR.txt

for example
FILE_A:
-------
A B C D 1
E F G H 2
I J K L 3

FILE_B:
-------
X E 2 M G
Y A 1 O T
for above two files, first row column of FILE_A (COL1, COL3 and COL5) are matching with
2nd row columns COL1B, COL1E and COL1C respectively of FILE_B, but for second row in FILE_A
they are not matching (COL3 not matching with COL1E).
what is the fastest possible way to do it using awk (or otherwise) ?
if i read line by line, it takes a lot of time as each file contains 50k++ records

Thanks in advance
:-)

FBSQL_FETCH_ARRAY(3)							 1						      FBSQL_FETCH_ARRAY(3)

fbsql_fetch_array - Fetch a result row as an associative array, a numeric array, or both

SYNOPSIS
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); ?> SEE ALSO
