用php插入一个CLOB

Question

大家好，我正在尝试将 base64 中的照片数据插入到 Oracle 数据库中的 CLOB 字段中，首先我尝试使用简单的 INSERT 语句，但我发现那不起作用。

所以我试试这个：

    $foto_data = $data->FOTOGRAFIA;

    $query = 'INSERT INTO "TMREPORTE" (
            "ID_REPORTE", 
            "NUMINT", 
            "NUMEXT", 
            "ENTRECALLE1", 
            "ENTRECALLE2", 
            "OBSERVACIONES", 
            "VISIBILIDAD", 
            "FOTOGRAFIA", 
            "LAT", 
            "LON", 
            "IDATENDIDO", 
            "FECHA_INGRESO", 
            "DIVICE_IDENTIFIER", 
            "ID_TIPO", 
            "ID_PRIORIDAD", 
            "ID_CPASENT", 
            "CALLE", 
            "FOLIO"
        ) VALUES (
            SEQ_TMREPORTE_IDREPORTE.NEXTVAL, 
            \''.xss_clean($data->NUMINT).'\', 
            \''.xss_clean($data->NUMEXT).'\', 
            \''.xss_clean($data->ENTRECALLE1).'\', 
            \''.xss_clean($data->ENTRECALLE2).'\', 
            \''.xss_clean($data->OBSERVACIONES).'\', 
            '.intval(xss_clean($data->VISIBILIDAD)).', 
            EMPTY_CLOB(),
            '.intval(xss_clean($data->LAT)).', 
            '.intval(xss_clean($data->LON)).', 
            0, 
            SYSDATE, 
            \''.xss_clean($data->DIVICE_IDENTIFIER).'\', 
            '.intval(xss_clean($data->ID_TIPO)).', 
            1, 
            '.intval(xss_clean($data->ID_CPASENT)).', 
            \''.xss_clean($data->CVE_VIALIDAD).'\', 
            \''.$rand_letter.'\'||\''.date( 'y', time() ).'\'||to_char(SEQ_TMREPORTE_IDREPORTE.NEXTVAL,\'FM0000\')
        ) RETURNING
            FOTOGRAFIA INTO :fotodata';

    $conn = $this->db->conn_id;

    $statement = oci_parse($conn, $query);
    $descriptor = oci_new_descriptor($conn, OCI_DTYPE_LOB);
    oci_bind_by_name($statement, ':fotodata', $descriptor, -1, OCI_B_CLOB);
    oci_execute($statement, 0);
    $descriptor->save($foto_data);
    oci_commit($conn);
    oci_free_descriptor($descriptor);

这段代码似乎有效，因为它不会给我发送任何错误，但在数据库中，FOTOGRAFIA 字段始终为空。

所以我尝试了一个不同的示例代码：

   $foto_data = $data->FOTOGRAFIA;

    $query = 'INSERT INTO "TMREPORTE" (
            "ID_REPORTE", 
            "NUMINT", 
            "NUMEXT", 
            "ENTRECALLE1", 
            "ENTRECALLE2", 
            "OBSERVACIONES", 
            "VISIBILIDAD", 
            "FOTOGRAFIA", 
            "LAT", 
            "LON", 
            "IDATENDIDO", 
            "FECHA_INGRESO", 
            "DIVICE_IDENTIFIER", 
            "ID_TIPO", 
            "ID_PRIORIDAD", 
            "ID_CPASENT", 
            "CALLE", 
            "FOLIO"
        ) VALUES (
            SEQ_TMREPORTE_IDREPORTE.NEXTVAL, 
            \''.xss_clean($data->NUMINT).'\', 
            \''.xss_clean($data->NUMEXT).'\', 
            \''.xss_clean($data->ENTRECALLE1).'\', 
            \''.xss_clean($data->ENTRECALLE2).'\', 
            \''.xss_clean($data->OBSERVACIONES).'\', 
            '.intval(xss_clean($data->VISIBILIDAD)).', 
            :fotodata,
            '.intval(xss_clean($data->LAT)).', 
            '.intval(xss_clean($data->LON)).', 
            0, 
            SYSDATE, 
            \''.xss_clean($data->DIVICE_IDENTIFIER).'\', 
            '.intval(xss_clean($data->ID_TIPO)).', 
            1, 
            '.intval(xss_clean($data->ID_CPASENT)).', 
            \''.xss_clean($data->CVE_VIALIDAD).'\', 
            \''.$rand_letter.'\'||\''.date( 'y', time() ).'\'||to_char(SEQ_TMREPORTE_IDREPORTE.NEXTVAL,\'FM0000\')
        )';

    $conn = $this->db->conn_id;

    $statement = oci_parse($conn, $query);
    oci_bind_by_name($statement, ':fotodata', $foto_data);
    oci_execute($statement);

但我得到了相同的结果，FOTOGRAFIA 字段中的值为空。

我对这个插入有点迷茫，你发现有什么错误吗？

这是我的表创建语句。
