yes indeed. I will have to change my column definitions. However, this behavior was not the case with 4.0.4. What seemed to be going on with that branch was I could have an 11 digit number, with a maximum of 9 digits behind the decimal. so numbers like 100493.43 were fine. I'm assuming that this

well, it appears that you are quite correct. changing the column definition to float(11,3) for example now does the correct thing. sean c peters wrote: This is not a bug, its behaving exactly as it should. When you specify a float(11,9) - you're saying an 11 digit number where 9 are after the de

I tend to use LOAD_FILE(), but your file has to be on the server and readable by MySQL ("INSERT INTO table ( field1, field2 ) VALUES ( 'a', LOAD_FILE( 'filepath' )" ). If you're using a programming language rather than just the MySQL client, you can also read the file into a variable and insert
