使用apoc.periodic.iterate 报错
发布于 1 个月前 作者 a835180269 82 次浏览 来自 问答

语句如下 CALL apoc.periodic.iterate(‘call apoc.load.jdbc(“myhive”,“select f_op_site,customer as cust_code,opsite_cust_cnt,opsite_cust_il,f_op_user_cnt,f_op_branch_cnt,f_channel_cnt,dt from rel_i_l0106002_opsite_cust where dt = 20170131 and f_op_site is not null and customer is not null and length(f_op_site) != 0 and length(customer) != 0 limit 99999999”) yield row return row as value’,‘MATCH (a:opsiteInfo),(b:custInfo) WHERE a.f_op_site = value.f_op_site AND b.cust_code = value.cust_code MERGE (a)-[r:L0106002{month:toInt(value.dt)/100}]->(b) on CREATE SET r += value,r.month = toInt(value.dt)/100 on MATCH SET r += value,r.month = toInt(value.dt)/100’, {batchSize:5000, parallel:true, iterateList:true})

执行2-3个批次就出会错

日志如上,这是为什么报错,求大神解答一下…
