oci_bind_array_by_name()

(PHP 5 >= 5.1.2, PHP 7, PECL OCI8 >= 1.2.0)

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

说明

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]]): bool

Binds the PHP array$var_arrayto the Oracle placeholder$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。

范例

Example #1 oci_bind_array_by_name() example

<?php
$conn = oci_connect("hr", "hrpwd", "localhost/XE");
if (!$conn) {
    $m = oci_error();
    trigger_error(htmlentities($m['message']), E_USER_ERROR);
}
$create = "CREATE TABLE bind_example(name VARCHAR(20))";
$stid = oci_parse($conn, $create);
oci_execute($stid);
$create_pkg = "
CREATE OR REPLACE PACKAGE ARRAYBINDPKG1 AS
  TYPE ARRTYPE IS TABLE OF VARCHAR(20) INDEX BY BINARY_INTEGER;
  PROCEDURE iobind(c1 IN OUT ARRTYPE);
END ARRAYBINDPKG1;";
$stid = oci_parse($conn, $create_pkg);
oci_execute($stid);
$create_pkg_body = "
CREATE OR REPLACE PACKAGE BODY ARRAYBINDPKG1 AS
  CURSOR CUR IS SELECT name FROM bind_example;
  PROCEDURE iobind(c1 IN OUT ARRTYPE) IS
    BEGIN
    -- Bulk Insert
    FORALL i IN INDICES OF c1
      INSERT INTO bind_example VALUES (c1(i));
    -- Fetch and reverse
    IF NOT CUR%ISOPEN THEN
      OPEN CUR;
    END IF;
    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;";
$stid = oci_parse($conn, $create_pkg_body);
oci_execute($stid);
$stid = oci_parse($conn, "BEGIN arraybindpkg1.iobind(:c1); END;");
$array = array("one", "two", "three", "four", "five");
oci_bind_array_by_name($stid, ":c1", $array, 5, -1, SQLT_CHR);
oci_execute($stid);
var_dump($array);
?>

Note that it looks like you can't bind a multi-dimensional array with this method. If you try, you'll get a Notice about Array to string conversion, and your PL/SQL will end up with a one-dimensional array filled with the a lot of string values, all saying "Array". :|

This function appears to work with PL/SQL associative arrays (index-by tables) but I was unable to get it to work with PL/SQL varrays

We were able to get the example included for the "OCI_BIND_ARRAY_BY_NAME" to work. However, the example is NOT actually binding with a PL/SQL array of any type. It is writing data to an Oracle table named "bind_example". Notice how this table is created. The table does NOT have an array type as one of its fields. Since this is the case, there cannot be any binding to a PL/SQL array because at least one field in the table must be either a VARRAY, NESTED TABLE or ASSOCIATIVE ARRAY data type. We searched the Internet and could not find any examples that actually read from a PL/SQL array type. We were able to get data from a PL/SQL VARRAY data type, but only by using a SELECT statement.
