It depends on exactly how you are uploading the .csv file to MySql but,
speaking generally, when you upload a string literal to a SQL server any
quotes in the literal that are also used to delimit the literal must be
"escaped". So if, say, you have Lionel 18" Train set. in a field
it must be written to the .csv file as ...,"Lionel 18\" Train
set.",.... if you are using double quotes to delimit string literals.
If you have, say, Lionel 18" Train set "Anniversary" model. in a
field the .csv entry should look like ...,"Lionel 18\" Train set
If you change the delimiter for character fields in the .csv file to
single quotes you shouldn't need to "escape" the " whether it is used to
indicate inches or not. MySQL should be quite happy to accept a .csv
file delimited with single quotes i.e ...,'Lionel 18" Train set
Using a single quotes as delimiter will also automatically take care of
any part_no values which contain double quotes. It does mean, of course,
that any apostrophes in the text will need to be escaped. You can't win
them all. :-)
Try the revised program attached if you don't have any apostrophe's in
any of your text fields.
drop table tmaster
create table tmaster (;
id numeric(11), ;
part_no char(10), ;
title char(35), ;
qty numeric(6,0), ;
sell numeric(7), ;
grade char(16), ;
mfg char(35), ;
cuml numeric(5,0), ;
sdate date, ;
asell numeric(7), ;
append from master for asell # 0 and title # null and part_no < "AF00760X"
msgbox( "Count is " +id+ ". The master.csv file must be ftped to the correct directory before importing into mysql." )
copy to tmaster.csv delim
cFileOut = 'tempworkfile.txt'
fIn = new file()
fOut = new file()
do while not fIn.eof()
cRead = fIn.gets()
If not chr(26)$cRead
