Just a note regarding the size of Oracle NUMBERS will always return 22 as their "size".
This seems to be an Oracle feature. The rest of the documentation is in bug5156.
oci_field_size
(PHP 5, PECL OCI8 >= 1.1.0)
oci_field_size — Returns field's size
Parametre
-
statement -
A valid OCI statement identifier.
-
field -
Can be the field's index (1-based) or name.
Returnerings Værdier
Returns the size of a field in bytes, or FALSE on
errors.
Eksempler
Eksempel #1 oci_field_size() example
<?php
$conn = oci_connect("scott", "tiger");
$stmt = oci_parse($conn, "SELECT * FROM emp");
oci_execute($stmt);
echo "<table border=\"1\">";
echo "<tr>";
echo "<th>Name</th>";
echo "<th>Type</th>";
echo "<th>Length</th>";
echo "</tr>";
$ncols = oci_num_fields($stmt);
for ($i = 1; $i <= $ncols; $i++) {
$column_name = oci_field_name($stmt, $i);
$column_type = oci_field_type($stmt, $i);
$column_size = oci_field_size($stmt, $i);
echo "<tr>";
echo "<td>$column_name</td>";
echo "<td>$column_type</td>";
echo "<td>$column_size</td>";
echo "</tr>";
}
echo "</table>";
oci_free_statement($stmt);
oci_close($conn);
?>
Noter
Note:
In PHP versions before 5.0.0 you must use ocicolumnsize() instead. This name still can be used, it was left as alias of oci_field_size() for downwards compatability. This, however, is deprecated and not recommended.
