MySQL LOAD DATA INFILE with comma as decimal separator

Question

How can I import a TSV file when the numbers use comma as a decimal separator?

LOAD DATA INFILE \'$filename\' INTO TABLE dados_meteo IGNORE 3 LINES 
($fields         


        

Answer 1

Try to replace ',' to '.' when loading.

For example -

LOAD DATA INFILE 'file.csv' INTO TABLE dados_meteo
(@var1, @var2)
SET column1 = REPLACE(@var1, ',', '.'), column2 = REPLACE(@var2, ',', '.')

Answer 2

If $field[0] is your numeric:

LOAD DATA INFILE '$filename' INTO TABLE dados_meteo IGNORE 3 LINES 
(@var1, $fields[1], $fields[2], $fields[3], $fields[4], $fields[5])
SET POM='$pom', $field[0] = CONVERT(REPLACE(@var1,',', ''), DECIMAL(10));

If more are numeric, simply repeat the pattern with a @var2, @var3, etc. You'll want to replace the DECIMAL(10) with whatever your field really is.
