Copy command and import - MS SQL Server to Postgres

[Goutam Paruchuri]

Iam trying to import data from ms-sql server to postgres. I export the
data which has datetime columns in sql server using BCP. I use the
following to import back into postgres.

copy tablename from 'c:\\bcpdata\\m cfa\\tablename. txt' with delimiter as
'\t'

I get the following error !!
invalid input syntax for type timestamp: ""

My input file has the timestamp value like

2004-09-30 11:31:00.000

Any clues ???


Thanks !
Goutam

I recently did the same thing, I left DELIMITER alone since \t is the
default, but I did have to do "WITH NULL as ''" since some of the
datetimes in MSSQL were empty.

By default the copy will bomb out on NULL fields even if you don't
have a NOT NULL constraint on the column, for one reason or another.

I suppose "WITH NULL as NULL" would've worked just as well, in hindsight.

What about the ".000" on the end? I am not able to enter that format in
a timestamp field in 7.4.5, it is invalid.

Nonsense.

regression=# select '2004-09-30 11:31:00.000':: timestamp;
timestamp
---------------------
2004-09-30 11:31:00
(1 row)

regression=# select '2004-09-30 11:31:00.001':: timestamp;
timestamp
-------------------------
2004-09-30 11:31:00.001
(1 row)

regression=# select '2004-09-30 11:31:00.000':: timestamptz;
timestamptz
------------------------
2004-09-30 11:31:00-04
(1 row)

Re: Copy command and import - MS SQL Server to Postgres

I know this doesn't answer your question, but have you considered doing it with DTS instead of BCP?
I used it recently to migrate an Access database to PostGreSQL and it worked great. One of the big advantages is the ability to transform the data as it is being converted.
It is also built in to MSSQL Server. I have used it numerous times for data transformations within SQL Server and have always enjoyed working with it.
