对MySQL负载数据执行计算

Question

我有以下两个sql语句

LOAD DATA LOCAL INFILE '~/data/geo_blocks.csv' INTO TABLE geo_blocks FIELDS  ENCLOSED BY '\"'TERMINATED BY ',' LINES TERMINATED BY '\n' (ip_start, ip_end, location_id);

＆安培;

update geo_blocks set index_geo = (ip_end - mod(ip_end, 65536));

是否有办法将LOAD DATA语句组合在一起同时执行计算？

Answer 1

您应该在LOAD DATA INFILE命令 -

中尝试SET子句

LOAD DATA LOCAL INFILE '~/data/geo_blocks.csv'
INTO TABLE geo_blocks
FIELDS ENCLOSED BY '\"'TERMINATED BY ','
LINES TERMINATED BY '\n'
(@ip_start, @ip_end, location_id)
SET index_geo = @ip_end - MOD(@ip_end, 65536);
