OCI_FIELD_SIZE(3)														 OCI_FIELD_SIZE(3)

oci_field_size - Returns field's size

int oci_field_size (resource $statement, mixed $field) DESCRIPTION
Returns the size of a $field. PARAMETERS
o $statement - A valid OCI statement identifier. o $field - Can be the field's index (1-based) or name. RETURN VALUES
Returns the size of a $field in bytes, or FALSE on errors. EXAMPLES
Example #1 oci_field_size(3) example <?php // Create the table with: // CREATE TABLE mytab (number_col NUMBER, varchar2_col varchar2(1), // clob_col CLOB, date_col DATE); $conn = oci_connect("hr", "hrpwd", "localhost/XE"); if (!$conn) { $m = oci_error(); trigger_error(htmlentities($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>"; echo "<th>Length</th>"; echo "</tr> "; $ncols = oci_num_fields($stid); for ($i = 1; $i <= $ncols; $i++) { $column_name = oci_field_name($stid, $i); $column_type = oci_field_type($stid, $i); $column_size = oci_field_size($stid, $i); echo "<tr>"; echo "<td>$column_name</td>"; echo "<td>$column_type</td>"; echo "<td>$column_size</td>"; echo "</tr> "; } echo "</table> "; // Outputs: // Name Type Length // NUMBER_COL NUMBER 22 // VARCHAR2_COL VARCHAR2 1 // CLOB_COL CLOB 4000 // DATE_COL DATE 7 oci_free_statement($stid); oci_close($conn); ?> NOTES
Note In PHP versions before 5.0.0 you must use ocicolumnsize(3) instead. This name still can be used, it was left as alias of oci_field_size(3) for downwards compatability. This, however, is deprecated and not recommended. SEE ALSO
oci_num_fields(3), oci_field_name(3). PHP Documentation Group OCI_FIELD_SIZE(3)
