Binds a PHP array to an Oracle PL/SQL array parameter

说明

bool oci_bind_array_by_name ( resource $statement , string $name , array &$var_array , int $max_table_length [, int $max_item_length = -1 [, int $type = SQLT_AFC ]] )

Binds the PHP array var_array to the Oracle placeholder name, which points to an Oracle PL/SQL array. Whether it will be used for input or output will be determined at run-time.

参数

statement

A valid OCI statement identifier.

name

The Oracle placeholder.

var_array

An array.

max_table_length

Sets the maximum length both for incoming and result arrays.

max_item_length

Sets maximum length for array items. If not specified or equals to -1, oci_bind_array_by_name() will find the longest element in the incoming array and will use it as the maximum length.

type

Should be used to set the type of PL/SQL array items. See list of available types below:

SQLT_NUM - for arrays of NUMBER.
SQLT_INT - for arrays of INTEGER (Note: INTEGER it is actually a synonym for NUMBER(38), but SQLT_NUM type won't work in this case even though they are synonyms).
SQLT_FLT - for arrays of FLOAT.
SQLT_AFC - for arrays of CHAR.
SQLT_CHR - for arrays of VARCHAR2.
SQLT_VCS - for arrays of VARCHAR.
SQLT_AVC - for arrays of CHARZ.
SQLT_STR - for arrays of STRING.
SQLT_LVC - for arrays of LONG VARCHAR.
SQLT_ODT - for arrays of DATE.

返回值

成功时返回 TRUE，或者在失败时返回 FALSE.

<?php

  PROCEDURE iobind(c1 IN OUT ARRTYPE);
END ARRAYBINDPKG1;";
$statement = oci_parse($c, $create_pkg);
oci_execute($statement);

$create_pkg_body = "
CREATE OR REPLACE PACKAGE BODY ARRAYBINDPKG1 AS

  PROCEDURE iobind(c1 IN OUT ARRTYPE) IS
    BEGIN
    FOR i IN 1..5 LOOP
      INSERT INTO bind_example VALUES (c1(i));
    END LOOP;
    IF NOT CUR%ISOPEN THEN
      OPEN CUR;

    FOR i IN REVERSE 1..5 LOOP
      FETCH CUR INTO c1(i);
      IF CUR%NOTFOUND THEN
        CLOSE CUR;
        EXIT;
      END IF;
    END LOOP;
  END iobind;
END ARRAYBINDPKG1;";
$statement = oci_parse($c, $create_pkg_body);
oci_execute($statement);

$statement = oci_parse($c, "BEGIN ARRAYBINDPKG1.iobind(:c1); END;");

$array = array("one", "two", "three", "four", "five");

oci_bind_array_by_name($statement, ":c1", $array, 5, -1, SQLT_CHR);

oci_execute($statement);

var_dump($array);
