bcp utf8 file

I'm outputting a file from a mySQL server that contains 1 column that
has input it many languages. The base definition for the column is
UTF8.

I output the data into a flat file and bcp it to a sql2000 server, and
the multi-byte data does not survive the translation.

Any ideas on how to input a UTF8 flat file into the server using BCP?

I've tried the -n -N -w options -- no luck.

thanks,

edAssuming that your destination column is nvarchar or nchar, then -w
should be the correct option; -n or -N are specific to MSSQL, so
they're unlikely to work. I've never used bcp to import a file like
that myself, so I can't really say for sure what the solution is, but
under "Copying Data Between Different Collations" in Books Online, it
suggests using a bcp format file with specific collations. You might
also try using DTS to import the data, as it's generally a lot smarter
than bcp, however again I've never tried importing a UTF8 file with it.

Since you cannot store UTF-8 data in SQL 2000 in any civilized way,
you need to first convert the file to UCS-2. (Or UTF_16 if you prefer.
I hope you are not using surrogates.)

A simple way to do this is to open the file in Notepad, and then change
encoding when you do Save As.

I'm a little uncertain how any byte-order mark would affect BCP.
Notepad is likely to add one, but I don't know if BCP is smart
enough to ignore it.

batch jobs

I'm looking for the definition of a batch job, what is it? How is it run? How does it differ from other jobs?

thx,

Kat

If i remember right

in query analyzer, a batch is a series of tsql statement

separated by keyword Go

select * from table1

select * from table 2

go

select * from table3

select * from table4

this query consist of two batch

batch as compared to stored procedure

is characterized by many roundtrips to the server

as compared to one round trip in SP

SP is enjoy cached execution as compared to

several process of parsing, compiling,optimizing and executing

a batch process
