DELIMITER $$ 
DROP procedure IF EXISTS pro_report_data $$  
CREATE procedure pro_report_data(in startT  varchar(100),in stopT  varchar(100),in buyerFilter varchar(20),gfs varchar(2000),qfs varchar(2000))  
BEGIN   
	declare colsStr varchar(2000);
	declare tableStr varchar(2000);
	declare whereStr varchar(2000);
	declare groupStr varchar(2000);
	declare sqls varchar(2000);
	
	call createReportSql4Other(null,null,0,buyerFilter,gfs,qfs,2,startT,stopT,0,colsStr,tableStr,whereStr,groupStr);
	set sqls= concat("select ",colsStr," from ",tableStr," where ",whereStr," group by ",groupStr);
	set @ms=sqls; 
	PREPARE s1 from @ms; 
	EXECUTE s1; 
	deallocate prepare s1;
