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,...) share|improve this answer answered Jul 2 '15 at 16:29 Aman Aggarwal 1,9902929 add a comment| up vote 0 down vote You are probably looking for REPLACE query. REPLACE INTO Users (Phone, Name, Email) VALUES ( Phone, Name, Email); share|improve this answer answered

Attempt 2: If I create the index on an empty table or make a combined private key and then put the data into the table, the table contains only 27 of 51 Mio. rows (!). Is there some kind of a limit on the unique index or a bug? I use MariaDB 10.0.20. Please help.
