Php 数据库oracle无法上载文件或图像

当我上传文件或图像时，oracle出现了一个错误。错误如下所示。每个人都有关于这个错误的经验吗？它和等号有关吗

ilDB Error: manipulate(MERGE INTO mob_usage a USING (SELECT 293 id, 
'cont:pg' usage_type, 1 usage_id, '-' usage_lang, 4 usage_hist_nr FROM 
DUAL) b ON (a.id = b.id AND a.usage_type = b.usage_type AND a.usage_id = 
b.usage_id AND a.usage_lang = b.usage_lang AND a.usage_hist_nr = 
b.usage_hist_nr) WHEN MATCHED THEN UPDATE SET WHEN NOT MATCHED THEN 
INSERT (a.id,a.usage_type,a.usage_id,a.usage_lang,a.usage_hist_nr) 
VALUES (b.id,b.usage_type,b.usage_id,b.usage_lang,b.usage_hist_nr))
MDB2 Error: unknown error

usage_type, 1 usage_id, '-' usage_lang, 4 usage_hist_nr FROM DUAL) b ON

AND a.usage_lang = b.usage_lang AND a.usage_hist_nr = b.usage_hist_nr) 
WHEN MATCHED THEN UPDATE SET WHEN NOT MATCHED THEN INSERT 
(a.id,a.usage_type,a.usage_id,a.usage_lang,a.usage_hist_nr) VALUES

code: 927] [Native message: ORA-00927: missing equal sign]
#0 

实际编码如下：

if ($lobs)  // delete/insert
        {
            $this->manipulate("DELETE FROM ".$a_table." WHERE ".
                implode ($delwhere, " AND ")
                );
            $this->insert($a_table, $a_columns);

            //$r = $this->db->extended->autoExecute($a_table, $field_values, MDB2_AUTOQUERY_INSERT, null, $types);
            $this->handleError($r, "replace, delete/insert(".$a_table.")");
        }
        else    // if no lobs are used, use manipulate
        {
            $q = "MERGE INTO ".$a_table." a ".
                "USING (SELECT ".implode($val_field, ", ")." ".
                "FROM DUAL) b ON (".implode($abpk, " AND ").") ".
                "WHEN MATCHED THEN UPDATE SET ".implode($aboc, ", ")." ".
                "WHEN NOT MATCHED THEN INSERT (".implode($a, ",").") VALUES (".implode($b, ",").")";
            $r = $this->manipulate($q);
        }

sql将如下所示：

MERGE INTO mob_usage a USING (SELECT 277 id, 'cont:pg' usage_type, 1 usage_id, '-' usage_lang, 16 usage_hist_nr FROM DUAL) b ON (a.id = b.id AND a.usage_type = b.usage_type AND a.usage_id = b.usage_id AND a.usage_lang = b.usage_lang AND a.usage_hist_nr = b.usage_hist_nr) WHEN MATCHED THEN UPDATE SET WHEN NOT MATCHED THEN INSERT
(a.id,a.usage_type,a.usage_id,a.usage_lang,a.usage_hist_nr) VALUES
(b.id,b.usage_type,b.usage_id,b.usage_lang,b.usage_hist_nr)

如果你在数据库上运行查询，它会工作吗？不，它不工作，我把我的查询。它与语句本身相关吗？首先尝试修复您的查询并使其正常工作。然后在你的代码中实现它是的，我试着运行oracle，它说缺少等号，我无法检测要放在哪个部分等号。你运行查询，因为它是在数据库上，它会工作吗？不，它不工作，我放我的查询。它与语句本身相关吗？首先尝试修复您的查询并使其正常工作。然后在你的代码中实现它是的，我试着运行oracle，它说缺少等号，我无法检测哪个部分应该放等号
