Error 1062. Duplicate entry in mysql

问题

I have a MySQL table whose schema in which column 1 is primary key. I have a tsv file which I need to insert in this table. Now, the tsv has repetition of primary key hence when I try to insert it in MySQL table it gives an error

ERROR 1062 (23000): Duplicate entry '107664521128181760' for key
'PRIMARY'

Is there any way by which if the primary key value already exists, then it should ignore and move further for next insertion.

回答1:

You are probably looking for INSERT IGNORE INTO command.

You can try like this:

INSERT IGNORE INTO yourtablename(col1,col2...)
values(val1,val2,...)

It depends on how you are importing the data.

If you are using LOAD DATA INFILE command then use IGNORE in command as:

LOAD DATA INFILE 'member.tsv'
IGNORE INTO TABLE tbl_member
FIELDS TERMINATED BY '\t'
LINES TERMINATED BY '\n'
(name, age);

And if you are using sql having INSERT command then use INSERT IGNORE in INSERT command as:

INSERT IGNORE INTO yourtablename(col1,col2...)
values(val1,val2,...)

You are probably looking for REPLACE query.

REPLACE INTO Users (Phone, Name, Email) VALUES ( Phone, Name, Email);
