When using LOAD DATA INFILE, is there a way to get the same functionality

  • 0

When using LOAD DATA INFILE, is there a way to get the same functionality provided by ON DUPLICATE KEY UPDATE of regular INSERT statements?

What I want to do is: for each line of my file, if the row doesn’t exist, a new row is inserted, otherwise the selected fields are updated.

My table has 5 columns: A, B, C, D and E. A is the primary key. Sometimes, I have to insert new rows with all the values, but sometimes I have to update only B and C, for example. But, the point is that I want to regroup all the INSERT or UPDATE in the same file.

Thanks

    If you want to insert/update some of fields, then you should load data into additional table, and then use INSERT, UPDATE or INSERT…SELECT+ON DUPLICATE KEY UPDATE statement to copy/modify data; otherwise other fields will be set to NULL.

    The REPLACE option in LOAD DATA INFILE won’t help you in this case.

    Also, you can use Data Import tool (CSV format) in dbForge Studio for MySQL (free express edition), just choose Append/Update import mode and specify fields mapping in the Data Import wizard.
