awk -F, 'BEGIN {OFS=","} print {$2,$3,$4}' $infile1
produces the desired output (with rows), but when echoing the variable below, the output is one continuous line
var1=$(awk -F, 'BEGIN {OFS=","} print... (4 Replies)

EXAMPLES
Example #1
oci_field_name(3) example
<?php
// Create the table with:
// CREATE TABLE mytab (number_col NUMBER, varchar2_col varchar2(1),
// clob_col CLOB, date_col DATE);
$conn = oci_connect("hr", "hrpwd", "localhost/XE");

$m = oci_error();
trigger_error(htmlentities($m['message']), E_USER_ERROR);

$stid = oci_parse($conn, "SELECT * FROM mytab");
oci_execute($stid, OCI_DESCRIBE_ONLY); // Use OCI_DESCRIBE_ONLY if not fetching rows
echo "<table border="1">
";
echo "<tr>";
echo "<th>Name</th>";
echo "<th>Type</th>";

$column_name = oci_field_name($stid, $i);
$column_type = oci_field_type($stid, $i);
echo "<tr>";
echo "<td>$column_name</td>";
echo "<td>$column_type</td>";
echo "</tr>

// CLOB_COL CLOB
// DATE_COL DATE
oci_free_statement($stid);
oci_close($conn);
?>
NOTES
Note
In PHP versions before 5.0.0 you must use ocicolumnname(3) instead. This name still can be used, it was left as alias of
oci_field_name(3) for downwards compatability. This, however, is deprecated and not recommended.
