I have one more query. If we know exactly which row to retrieve then this will work fine. Suppose the given dat file contains thousands of records, I just want to retrieve all the rows whose salary is greater tha 15000. How can v acheive that ? In other words can v use expressions(logical,arthmetic, regular...) to retireve the particular rows along with the column name..
yes you can
Code:
 
awk 'BEGIN{NR==1{print}$3>15000{print}' filename

SYNOPSIS
array mssql_fetch_row (resource $result) DESCRIPTION
mssql_fetch_row(3) fetches one row of data from the result associated with the specified result identifier. The row is returned as an array. Each result column is stored in an array offset, starting at offset 0. Subsequent call to mssql_fetch_row(3) would return the next row in the result set, or FALSE if there are no more rows. PARAMETERS
o $result - The result resource that is being evaluated. This result comes from a call to mssql_query(3). RETURN VALUES
Returns an array that corresponds to the fetched row, or FALSE if there are no more rows. EXAMPLES
Example #1 mssql_fetch_row(3) example <?php // Connect to MSSQL and select the database $link = mssql_connect('MANGOSQLEXPRESS', 'sa', 'phpfi'); mssql_select_db('php', $link); // Query to execute $query = mssql_query('SELECT [id], [quote] FROM [quotes] WHERE [id] = '42'', $link); // Did the query fail? if (!$query) { die('MSSQL error: ' . mssql_get_last_message()); } // Fetch the row $row = mssql_fetch_row($query); // Print the 'quote' echo 'Quote #' . $row[0] . ': "' . $row[1] . '"'; ?> The above example will output something similar to: Quote #42: "The answer to everything..." NOTES
Note This function sets NULL fields to the PHP NULL value. SEE ALSO
