Reformatting the code, adding comments, removing some unneeded quotes, and adding a pair of missing quotes, the script could be rewritten as:
Code:
# Loop through every file in the current directory with a filename ending in
# "file" setting the shell variable file to the name of one of those files.
for file in *file
do
# Run awk for one file...
awk '
{ # Set the awk variable s to "name" (in quotes) if this is the
# 1st line from this file; otherwise set it to the name of the
# current input file (in quotes).
s = FNR==1 ? "\"name\"" : "\""FILENAME"\""
# Print the awk variable s followed by the output field
# separator followed by the current input line.
print s,$0
# Set the output field separator to a comma, reading input from the
# file named by the shell variable file and directing the
# output to a file named by the shell variable file preceeded by
# the string "New_".
}' OFS=',' "$file" >"New_$file"
done
Does this explain what you wanted to know?

odbc_fetch_row
ODBC_FETCH_ROW(3) 1 ODBC_FETCH_ROW(3)odbc_fetch_row - Fetch a rowSYNOPSIS
bool odbc_fetch_row (resource $result_id, [int $row_number])
DESCRIPTION
Fetches a row of the data that was returned by odbc_do(3) or odbc_exec(3). After odbc_fetch_row(3) is called, the fields of that row can
be accessed with odbc_result(3).
PARAMETERS
o $result_id
- The result identifier.
o $row_number
- If $row_number is not specified, odbc_fetch_row(3) will try to fetch the next row in the result set. Calls to odbc_fetch_row(3)
with and without $row_number can be mixed. To step through the result more than once, you can call odbc_fetch_row(3) with
$row_number 1, and then continue doing odbc_fetch_row(3) without $row_number to review the result. If a driver doesn't support
fetching rows by number, the $row_number parameter is ignored.
RETURN VALUES
Returns TRUE if there was a row, FALSE otherwise.
