使用PHP 5.3.2和Oracle 11G,我试图将数组从PHP传递到oracle存储的proc中.这是我的PL / SQL:
create or replace type NUM_ARRAY as table of number;
create or replace package txa as
procedure upsert_txa_compliance_slct( v_compl_id_array in num_array);
end txa;
create or replace package body txa as
procedure upsert_txa_compliance_slct(v_compl_id_array in num_array)
is
begin
.
. -- sql code removed for brevity. package and body compile no errors
.
end upsert_txa_compliance_slct;
end;
查询:
$sql = "begin txa.upsert_txa_compliance_slct(:my_array); end;";
还有我尝试绑定数组并执行的PHP代码:
第一:
<?
$this->conn = ociplogon($dbuser, $dbpass, $dbname);
$this->commit_mode = OCI_COMMIT_ON_SUCCESS;
$this->sth = @ociparse($this->conn, $sql);
oci_bind_array_by_name($this->sth,
':my_array',
$my_array,
count($my_array),
-1,
SQLT_CHR);
$r = @ociexecute($this->sth, $this->commit_mode);
?>
产生此错误:
PLS-00306:“ UPSERT_TXA_COMPLIANCE_SLCT”调用中参数的数量或类型错误
我显然传递了1个参数.那么,怎么回事/如何解决类型问题?
另外我发现了这个
http://www.oracle.com/technetwork/articles/seliverstov-multirows-098120.html
并使用oci收集以旧方式进行了尝试,如下所示:
$collection = oci_new_collection($this->conn,"NUM_ARRAY");
在将我的oracle类型更改为此后:
create or replace type NUM_ARRAY as varray(100) of number;
我收到此错误:
oci_new_collection():ORA-22318:输入类型不是数组类型
任何帮助将非常感激.

我将我的php oci_bind函数调用更改为使用SQLT_NUM作为类型.这没有影响.然后,我将包裹更改为包括:
type num_array is table of number index by binary_integer;
(我还从我的架构中删除了原始的num_array)
此更改使将数组传递给存储的proc成为可能,但是这样我就不能将数组用作嵌套表,如下所示:
delete
from my_table
where id not in (select column_value from table(v_compl_id_array));
当我尝试使用其中的语句编译程序包主体时,出现此错误:
PL/SQL: ORA-22905: cannot access rows from a non-nested table item
而且所有文档都告诉我要返回架构级别类型?但是,当我这样做时,我会遇到其他错误.我知道我可以找到另一种方法来使用pl / sql数组上的循环,但是我真的很希望能够使用该架构级别类型.
解决方法:
答案是这样.您不能使用全局创建的或架构级别的类型作为存储过程的参数. PHP的oci_bind_array_by_name似乎不适用于全局创建的类型,但是您需要全局创建的类型才能将数组用作子选择中的嵌套表.所以….这就是我如何使它工作的.我非常高兴听到其他解决方案!但是现在,这就是我所做的.
-- globally create a type table of number
create or replace type num_array is table of number;
-- in my package i created an internal type table of number
type i_num_array is table of number index by binary_integer;
-- i then used i_num_array (internal type) as the type for my IN parameter to the procedure
upsert_TXA_compliance_slct( v_compl_id_array in i_num_array)
-- in my procedure i also created a variable that is the type of my globally created type
v_num_array num_array := num_array();
-- then i populated that variable in a loop inside my procedure with the values in my IN param
for i in 1 .. v_compl_id_array.count
loop
v_num_array.extend(1);
v_num_array(i) := v_compl_id_array(i);
end loop;
-- then i used v_num_array as my nested table so this now works:
delete from my_table where id in (select * from table(v_num_array));
