Im passing table name & column name which im selecting from cursor.But its inserting correctly and also showing error like cursor is not open .

my proc is as:

CREATE OR REPLACE PROCEDURE TEST_BUILDINGCODE_PROC (IN v_AppId_Ver INTEGER)
BEGIN
	
	DECLARE v_ObjId,v_LayerName,v_TableName,v_ColumnName varchar(30);
	DECLARE v_CodeNo,v_DataCount integer;
	DECLARE v_Statement,v_Schema,v_Counter varchar(200);
	DECLARE v_stmt STATEMENT;
	
	DECLARE  C1 CURSOR WITH RETURN FOR
	SELECT IDVER,LAYERNAME,CODENO,TABLENAME,COLUMNNAME FROM MPD2021.DA_TEST_LAYERCODE WHERE IDVER=v_AppId_Ver;
	
	SET v_Schema='MPD2021';
	
	SET v_DataCount=(SELECT COUNT(*) FROM MPD2021.DA_TEST_LAYERCODE WHERE IDVER=v_AppId_Ver);
	SET v_Counter=1;
	OPEN C1;
	WHILE(v_Counter<=v_DataCount)
	DO
		
		FETCH C1 INTO v_ObjId,v_LayerName,v_CodeNo,v_TableName,v_ColumnName;
		--SET v_Schema='KKD';
		SET v_Statement ='INSERT  INTO  ' || v_Schema || '. '|| v_TableName ||'(IDVERSION,'||v_ColumnName||') VALUES('||v_AppId_Ver||','||v_CodeNo||')';
		--set v_Statement='INSERT INTO MPD2021.' concat  v_Schema concat ' VALUES ( 'concat ' 4 ' concat ')';
		
		--SET v_Statement = 'INSERT  INTO  ' || v_Schema || '. '|| v_TableName ||'('||v_ColumnName||') VALUES('||3||')';
		PREPARE v_stmt FROM v_Statement;	
		EXECUTE v_stmt;
		COMMIT;

		--INSERT INTO TabName (IDVERSION,OBJID,LAYER,v_ColumnName) VALUES(v_AppId_Ver,v_ObjId,v_LayerName,v_CodeNo);
		
--	SET	v_DataCount=v_DataCount-1;
	SET v_Counter = v_Counter + 1;	
	END WHILE;
	CLOSE C1;
