importing a CSV into phpmyadmin

Question

I have a CSV that looks like this,

candidate_id,show_on_site,first_name,surname,gender,DOB,showdob,Location,height,eyes,hair_colour,hair_length,accents,union         


        

Answer 1

Using the LOAD DATA INFILE SQL statement you can import the CSV file, but you can't update data. However, there is a trick you can use.

• Create another temporary table to use for the import

• Load onto this table from the CSC

  LOAD DATA LOCAL INFILE '/file.csv'
  INTO TABLE temp_table
  FIELDS TERMINATED BY ','
  LINES TERMINATED BY '\n'
  (field1, field2, field3); 
  

• UPDATE the real table joining the table

  UPDATE maintable
  INNER JOIN temp_table A USING (field1)
  SET maintable.field1 = temp_table.field1
