oci_error

(PHP 5)

oci_error -- Returns the last error found

Description

array oci_error ( [resource source])

For most errors, the parameter is the most appropriate resource handle. For connection errors with oci_connect(), oci_new_connect() or oci_pconnect(), do not pass a parameter. If no error is found, oci_error() returns FALSE. oci_error() returns the error as an associative array. In this array, code consists the oracle error code and message the oracle error string.

As of PHP 4.3: offset and sqltext will also be included in the return array to indicate the location of the error and the original SQL text which caused it.

例 1. Displaying the Oracle error message after a connection error

$conn = @oci_connect("scott", "tiger", "mydb");
if (!$conn) {
  $e = oci_error();   // For oci_connect errors pass no handle
  echo htmlentities($e['message']);
}

例 2. Displaying the Oracle error message after a parsing error

$stmt = @oci_parse($conn, "select ' from dual");  // note mismatched quote
if (!$stmt) {
  $e = oci_error($conn);  // For oci_parse errors pass the connection handle
  echo htmlentities($e['message']);
}

例 3. Displaying the Oracle error message and problematic statement after an execution error

$r = oci_execute($stmt);
if (!$r) {
  $e = oci_error($stmt); // For oci_execute errors pass the statementhandle
  echo htmlentities($e['message']);
  echo "<pre>";
  echo htmlentities($e['sqltext']);
  printf("\n%".($e['offset']+1)."s", "^");
  echo "</pre>";
}

注意: In PHP versions before 5.0.0 you must use ocierror() instead. This name still can be used, it was left as alias of oci_error() for downwards compatability. This, however, is deprecated and not recommended.
