In one of my assignment problem, I need to read an input file that has 131262 lines.
Following is my code for reading the input:
create table batsman_scored(
id int(10) unsigned auto_increment primary key,
match_id int(10),
over_id int(10),
ball_id int(10),
runs_scored int(10),
innings_no int(10)
);
load data local infile "data/batsman_scored.csv"
into table batsman_scored
fields terminated by ','
lines terminated by '\n'
ignore 2 rows
;
The problem is, for some reason, MySQL is not reading the whole file, instead, it is getting terminated after few lines. I checked the input files, and there is nothing suspicious there. Mysql output:
Query OK, 568 rows affected, 65535 warnings (0.50 sec)
Records: 131260 Deleted: 0 Skipped: 130692 Warnings: 261952
Can someone tell, why it's skipping so many rows? When does MySQL skip rows?
I checked that MySQL can store a lot more than 568
.
I am still waiting for an answer here, but commenting the auto_increment
line:
create table batsman_scored(
// id int(10) unsigned auto_increment primary key,
match_id int(10),
over_id int(10),
ball_id int(10),
runs_scored int(10),
innings_no int(10)
);
load data local infile "data/batsman_scored.csv"
into table batsman_scored
fields terminated by ','
lines terminated by '\n'
ignore 2 rows
;
