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), butSQLT_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.
