mysql GROUP_CONCAT过大数据无法显示全解决方案

在MySQL Server 5.1/my.ini 文件中在

max_connections=2000

后边增加

group_concat_max_len=102400

sql语句如下:

get OfficeGrid all precaution count sql:

select count(r.precautionLevel) from (select r.precautionLevel ,r.creatorid,r.domainid,r.nameen,r.namecn,r.requiredTime,GROUP_CONCAT(p.nameEN SEPARATOR ';') as pnameEN,GROUP_CONCAT(p.nameCN SEPARATOR ';') as pnameCN from precautiontable r,precautionproductrelationtable
o,producttable p where 1=1 and r.ID = o.precuationID and o.productID=p.ID and r.deleteflag=0 and o.deleteflag=0 and p.deleteflag=0 group by r.ID) r left join precautionleveltable plt on r.precautionLevel = plt.id left join usertable u on r.creatorid=u.id left
join basicstatictable b on r.domainid=b.id where 1=1 {0} and plt.deleteflag=0

get OfficeGrid all precaution infolist:
