将PHP数组传递到Oracle Stored Proc(PLS-00306:错误的参数数目或类型) [英] passing PHP array to Oracle Stored Proc (PLS-00306: wrong number or types of arguments)

问题描述

我使用PHP 5.3.2和Oracle 11G，试图将数组从PHP传递到oracle存储的proc中.这是我的PL/SQL:

Using PHP 5.3.2 and Oracle 11G, I'm trying to pass an array from PHP into an oracle stored proc. Here is my 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:

And the PHP Code I've tried to bind the array and execute :

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);

?>

哪个会产生此错误:

PLS-00306:调用"UPSERT_TXA_COMPLIANCE_SLCT"时参数的数量或类型错误

PLS-00306: wrong number or types of arguments in call to 'UPSERT_TXA_COMPLIANCE_SLCT'

我显然要传递1个arg.那么，这是什么问题/如何解决类型问题?

I'm clearly passing 1 arg. So, what's wrong with/how do I fix the type issue?

另外我发现了

http://www.oracle.com/technetwork/articles/seliverstov-multirows-098120.html

并使用oci收集以旧方式进行尝试，如下所示:

And tried it the old way using oci collection like so:

 $collection = oci_new_collection($this->conn,"NUM_ARRAY");

将我的oracle类型更改为此后:

After I changed my oracle type to this:

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

oci_new_collection(): ORA-22318: input type is not an array type

任何帮助将不胜感激.

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:

I changed my php oci_bind function call to use SQLT_NUM as the type. This had no impact. Then I changed my package to include:

type num_array is table of number index by binary_integer;

(我也从架构中删除了原始的num_array)

( i also dropped the original num_array from my schema )

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，就像这样:

This change made it possible to pass my array to the stored proc, but then I can't use the array as a nested table like so:

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:

I get this error when i try to compile the package body with that statement in it:

PL/SQL: ORA-22905: cannot access rows from a non-nested table item

所有文档都告诉我要返回架构级别类型吗?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，可以在我的pl/sql数组上使用循环，但是我真的很希望能够使用该架构级别类型.

And all the documentation tells me to return to the schema level type? But when I do I get that other error. I know I can find another way to do this using a loop over my pl/sql array, but I would really love to be able to use that schema level type.

推荐答案

答案是这样的.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.

The answer is this. You can't use a globally created or schema level type as a parameter to a stored procedure. PHP's oci_bind_array_by_name just doesn't seem to work with globally created types, but you need the globally created type to be able to use your array as a nested table in subselects. So.... here is how I got this to work. I'm MORE THAN HAPPY TO HEAR OTHER SOLUTIONS!! but for now, here's what I did.

-- 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));
