从PHP调用Oracle存储过程

Question

我正在尝试执行并从我的过程中获取数据:

这是我的程序定义方式:

create or replace PROCEDURE SP_GET_MY_DATA(
         IN_POP VARCHAR2,
         IN_SEG VARCHAR2,
         IN_DUR VARCHAR2, 
         IN_VIEW INTEGER, 
         IN_PAGE INTEGER, 
         VIEW_DATA_CUR OUT SYS_REFCURSOR) AS ...

这是我的PHP代码,用于执行和从过程中获取数据:

$db = "(DESCRIPTION=(ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = JXYX.com)(PORT = 1521)))(CONNECT_DATA=(SID=DHSJKS)))";
$conn = ocilogon("XXXXXX","XXXXXXXX",$db);          

$sql = 'BEGIN SP_GET_MY_DATA(:POP, :SEG, :DUR, :VIEW, :PAGE, :OUTPUT_CUR); END;';            

$stmt = oci_parse($conn,$sql);                     
oci_bind_by_name($stmt,':POP',$pop);           
oci_bind_by_name($stmt,':SEG',$seg);           
oci_bind_by_name($stmt,':DUR',$dur);           
oci_bind_by_name($stmt,':VIEW',$view);           
oci_bind_by_name($stmt,':PAGE',$page);           
$OUTPUT_CUR = oci_new_cursor($conn);
oci_bind_by_name($stmt,":OUTPUT_CUR", $OUTPUT_CUR, -1, OCI_B_CURSOR);                   
oci_execute($stmt, OCI_DEFAULT); 

while ($data = oci_fetch_assoc($OUTPUT_CUR)) {
    print_r($data);
}

但是这样做我收到了这个错误:

oci_fetch_assoc():ORA-24374:在获取或执行之前定义未完成并获取".

我无法弄清楚我错过了什么.你能帮我吗？

与直接从SELECT语句访问行相比,要在PHP中使用游标,还需要三个额外的步骤.

• 第一步是使用oci_new_cursor()函数在PHP中准备游标资源,然后使用该函数绑定到适当的参数.
• 第二步是在oci_bind_by_name()函数 上添加一个参数
• 执行通常的SQL语句后,第三步是调用oci_execute()游标资源.

代码:

//Connection does not change
$db = "(DESCRIPTION=(ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = JXYX.com)(PORT = 1521)))(CONNECT_DATA=(SID=DHSJKS)))";
$conn = ocilogon("XXXXXX","XXXXXXXX",$db);          

//Request does not change
$sql = 'BEGIN SP_GET_MY_DATA(:POP, :SEG, :DUR, :VIEW, :PAGE, :OUTPUT_CUR); END;';            

//Statement does not change
$stmt = oci_parse($conn,$sql);                     
oci_bind_by_name($stmt,':POP',$pop);           
oci_bind_by_name($stmt,':SEG',$seg);           
oci_bind_by_name($stmt,':DUR',$dur);           
oci_bind_by_name($stmt,':VIEW',$view);           
oci_bind_by_name($stmt,':PAGE',$page);    

//But BEFORE statement, Create your cursor
$cursor = oci_new_cursor($conn)

// On your code add the latest parameter to bind the cursor resource to the Oracle argument
oci_bind_by_name($stmt,":OUTPUT_CUR", $cursor,-1,OCI_B_CURSOR);

// Execute the statement as in your first try
oci_execute($stmt);

// and now, execute the cursor
oci_execute($cursor);

// Use OCIFetchinto in the same way as you would with SELECT
while ($data = oci_fetch_assoc($cursor, OCI_RETURN_LOBS )) {
    print_r($data}
}

我不太熟悉Oracle(英语),所以你应该阅读本教程.有一个有趣的例子,请看存储过程和参考游标章节!

希望能帮助到你!
