Examples
Example #1 oci_field_precision() Example
<?php// Create the table with:// CREATE TABLE mytab (c1 NUMBER, c2 FLOAT, c3 NUMBER(4), c4 NUMBER(5,3));$conn = oci_connect("hr", "hrpwd", "localhost/XE");if (!$conn) { $m = oci_error(); trigger_error(htmlentities($m['message']), E_USER_ERROR);}$stid = oci_parse($conn, "SELECT * FROM mytab");oci_execute($stid, OCI_DESCRIBE_ONLY); // Use OCI_DESCRIBE_ONLY if not fetching rows$ncols = oci_num_fields($stid);for ($i = 1; $i <= $ncols; $i++) { echo oci_field_name($stid, $i) . " " . oci_field_precision($stid, $i) . " " . oci_field_scale($stid, $i) . "<br>\n";}// Outputs:// C1 0 -127// C2 126 -127// C3 4 0// C4 5 3oci_free_statement($stid);oci_close($conn);?>
Notes
Note:
In PHP versions before 5.0.0 you must use ocicolumnprecision() instead. This name still can be used, it was left as alias of oci_field_precision() for downwards compatability. This, however, is deprecated and not recommended.
