(PHP 5, PHP 7, PECL OCI8 >= 1.1.0)
oci_error — Returns the last error found
$resource
] )Returns the last error found.
The function should be called immediately after an error occurs. Errors are cleared by a successful statement.
resource
For most errors, resource is the
resource handle that was passed to the failing function call.
For connection errors with oci_connect(),
oci_new_connect() or
oci_pconnect() do not pass resource.
If no error is found, oci_error() returns
FALSE. Otherwise, oci_error() returns the
error information as an associative array.
| Array key | Type | Description |
|---|---|---|
| code | integer | The Oracle error number. |
| message | string | The Oracle error text. |
| offset | integer | The byte position of an error in the SQL statement. If there was no statement, this is 0 |
| sqltext | string | The SQL statement text. If there was no statement, this is an empty string. |
Example #1 Displaying the Oracle error message after a connection error
<?php
$conn = oci_connect("hr", "welcome", "localhost/XE");
if (!$conn) {
$e = oci_error(); // For oci_connect errors do not pass a handle
trigger_error(htmlentities($e['message']), E_USER_ERROR);
}
?>
Example #2 Displaying the Oracle error message after a parsing error
<?php
$stid = oci_parse($conn, "select ' from dual"); // note mismatched quote
if (!$stid) {
$e = oci_error($conn); // For oci_parse errors pass the connection handle
trigger_error(htmlentities($e['message']), E_USER_ERROR);
}
?>
Example #3 Displaying the Oracle error message, the problematic statement, and the position of the problem of an execution error
<?php
$stid = oci_parse($conn, "select does_not_exist from dual");
$r = oci_execute($stid);
if (!$r) {
$e = oci_error($stid); // For oci_execute errors pass the statement handle
print htmlentities($e['message']);
print "\n<pre>\n";
print htmlentities($e['sqltext']);
printf("\n%".($e['offset']+1)."s", "^");
print "\n</pre>\n";
}
?>
