请求大佬帮助！！！

通过mybatis 调用存储过程，一直提示字符串转换出错。

存储过程定义如下：

CREATE OR REPLACE PROCEDURE PC_SP_35_05_T_W
(
code OUT INT,
parentnodetype INT, 
parentnodeid INT, 
updatetime DATETIME,
bupdateduplicate INT
)
AS
Declare
mergeSQL NVARCHAR(3000);
  duplicateCount INT;
  maxUpdateTime DATETIME;
  updateTimeCode INT;
BEGIN

  IF (parentNodeType IS NULL) OR (parentNodeType<0) THEN
	  code = -101;
	  RETURN;
END IF;
  IF (parentNodeID IS NULL) OR (parentNodeID<0) THEN
	  code = -102;
	  RETURN;
END IF;
  IF (updateTime IS NULL) THEN
	  code = -103;
	  RETURN;
END IF;
  IF (bUpdateDuplicate IS NULL) OR (bUpdateDuplicate<0) THEN
	code = -104;
	RETURN;
END IF;
  -- 调整 maxUpdateTime 的计算逻辑
  maxUpdateTime = updateTime;
  IF (bUpdateDuplicate > 0) THEN
    EXECUTE IMMEDIATE 'SELECT COUNT(*) FROM PC_TB_05 a, TEMP_WRITESETUPNODES b WHERE a.NODETYPE = b.NODETYPE AND a.NODEID = b.NODEID' INTO duplicateCount;
    IF (duplicateCount > 0) THEN
      EXECUTE IMMEDIATE 'SELECT MAX(a.updatetime) FROM PC_TB_05 a, TEMP_WRITESETUPNODES b WHERE a.NODETYPE = b.NODETYPE AND a.NODEID = b.NODEID' INTO maxUpdateTime;
      IF (maxUpdateTime >= updateTime) THEN
        maxUpdateTime = maxUpdateTime + INTERVAL '1' SECOND;
      ELSE
        maxUpdateTime = updateTime;
      END IF;
    END IF;
  END IF;
 
  -- 修改 MERGE 语句的 ON 条件
  mergeSQL = 'MERGE INTO PC_TB_05 DEST USING TEMP_WRITESETUPNODES SRC
      ON (SRC.NODETYPE = DEST.NODETYPE AND SRC.NODEID = DEST.NODEID)
      WHEN NOT MATCHED THEN
        INSERT VALUES(src.nodeType, src.nodeID, src.nodeInternalName,
        src.nodeName, src.version, src.parentNodeType, src.parentNodeID,
        ?, src.dataLength, src.data) ';
 
  -- 修改 WHEN MATCHED 分支，显式更新父节点字段
  IF (bUpdateDuplicate > 0 AND duplicateCount > 0) THEN
    mergeSQL = mergeSQL || ' WHEN MATCHED THEN
      UPDATE SET 
        dest.PARENTNODETYPE = src.PARENTNODETYPE,
        dest.PARENTNODEID = src.PARENTNODEID,
        dest.nodeName = src.nodeName,
        dest.version = src.version,
        dest.updateTime = ?,
        dest.dataLength = src.dataLength,
        dest.data = src.data';
    EXECUTE IMMEDIATE mergeSQL USING maxUpdateTime, maxUpdateTime;
  ELSE
    EXECUTE IMMEDIATE mergeSQL USING maxUpdateTime;
  END IF;
 
  -- 调用更新父节点时间的函数
  updateTimeCode = updateparentnodetime(PC_SP_35_05_t_w.parentNodeType, PC_SP_35_05_t_w.parentNodeID, PC_SP_35_05_t_w.updatetime, 'PC_TB_05');
  RETURN;
END;
