我有这个 ORA 存储过程：

procedure calc(code in number, extLoan in number, loan in number, payment in number, duration in number, saleId in number, resultBlob out clob);

（目前只有这个标题可用）。

我已经尝试过这个 PHP 调用（我oci_*直接使用函数，尽管我们为它们提供了一个包装器对象）：

$query = '
BEGIN 
    calc(
        :code,
        :extLoan,
        :loan,
        :payment,
        :duration,
        :saleId,
        :result); 
END;';

$stmt = oci_parse($this->connection, $query);

oci_bind_by_name($stmt, ':code', 100, 3, SQLT_INT);
oci_bind_by_name($stmt, ':extLoan', 20000, 9, SQLT_INT);
oci_bind_by_name($stmt, ':loan', 50000, 9, SQLT_INT);
oci_bind_by_name($stmt, ':payment', 0, 9, SQLT_INT);
oci_bind_by_name($stmt, ':duration', 60, 3, SQLT_INT);
oci_bind_by_name($stmt, ':saleId', 2211445, 9, SQLT_INT); // <- this row is generating the error

// also tried these binds with no luck (same error)
//oci_bind_by_name($stmt, ':code', 100);
//oci_bind_by_name($stmt, ':extLoan', 20000);
//oci_bind_by_name($stmt, ':loan', 50000);
//oci_bind_by_name($stmt, ':payment', 0);
//oci_bind_by_name($stmt, ':duration', 60);
//oci_bind_by_name($stmt, ':saleId', 2211445);

$desc = oci_new_descriptor($this->connection, OCI_D_LOB);
oci_bind_by_name($stmt, ':result', $desc, -1, OCI_B_CLOB);

oci_execute($stmt, OCI_DEFAULT); // <- here the error occurs...

现在，如您所见，所有SQLT_INT绑定都是纯整数。该过程还等待数字进入......但ORA-01722 invalid number发生错误。

现在如果我改变

oci_bind_by_name($stmt, ':saleId', 2211445, 9, SQLT_INT);

至

oci_bind_by_name($stmt, ':saleId', 2211445, 9, SQLT_NUM);

执行产生另一个错误：ORA-01403 no data found。

我最终尝试的是这个电话：

$query = '
BEGIN 
    calc(
        100,
        20000,
        50000,
        0,
        60,
        2211445,
        :result); 
END;';

$stmt = oci_parse($this->connection, $query);

$desc = oci_new_descriptor($this->connection, OCI_D_LOB);
oci_bind_by_name($stmt, ':result', $desc, -1, OCI_B_CLOB);

oci_execute($stmt, OCI_DEFAULT); // <- here the error occurs...

但我仍然得到同样的ORA-01722 invalid number错误。

我还尝试直接在以下位置运行查询sql developer：

DECLARE
  code NUMBER := 100;
  extLoan NUMBER := 20000;
  loan NUMBER := 50000;
  payment NUMBER := 0;
  duration NUMBER := 60;
  saleId NUMBER := 2211445;
  cclob CLOB;
BEGIN
  calc(
    code,
    extLoan,
    loan,
    payment,
    duration,
    saleId,
    cclob);
  dbms_output.put_line(cclob);
END;

并且该语句已成功执行，而输出按预期输出。

您知道可能导致问题的原因吗？？？

编辑 1：有趣的是，如果我在SQL developer

saleId VARCHAR2(7) := '2211445';

（而不是之前的saleId NUMBER := 2211445;）该过程仍然没有错误地执行，转换/转换成功......

编辑2： 为确保问题不在于描述符或CLOB变量绑定，我尝试了下一个调用（其余相同）：

$this->db->parseQuery('
DECLARE
    code NUMBER := :code;
    extloan NUMBER := :extloan;
    loan NUMBER := :loan;
    payment NUMBER := :payment;
    duration NUMBER := :duration;
    saleId NUMBER := :saleid;
    myclob CLOB;
BEGIN 
    calc(
        code,
        extloan,
        loan,
        payment,
        duration,
        saleId,
        myclob);
    :myclob := myclob;

    EXCEPTION WHEN OTHERS THEN
        :myclob := \'<params>
    <code>\' || code || \'</code>
    <extloan>\' || extloan || \'</extloan>
    <loan>\' || loan || \'</loan>
    <payment>\' || payment || \'</payment>
    <duration>\' || duration || \'</duration>
    <saleId>\' || saleId || \'</saleId>
</params>\';
END;');

删除了绑定，但绑定CLOB和输出 ( $lob->load();)返回了正确的 XML 字符串，其中包含传入的所有值...

我想现在很明显问题出在其他地方并且描述符/ clob 绑定是可以的......
