Обсуждение: mssql to postgres problems with bytea help needed

Hi all,

I've successfully converted a huge mssql ddl to postgres 8.1.9 - I
could upgrade if need be. We run both db's for our app depending on
the customer. We have a new feature, storing serialized java objects
in the db, and I'm having trouble with on this insert:

INSERT INTO

If that line is not showing up on your newsreader, please see this

When inserting, I get: ERROR:  syntax error at or near "xACED0005
<snip>

I've been googling / reading the docs and I tried several things that
have not worked, but thought I'd post here while I'm trying solutions.
Any ideas? I'm open to any cast or modifying the insert to use psql
functions, etc.

Thanks!
Robert

The syntax for specifying "BLOB literals" is a bit different in Postgres. You need to encode the bytes as octal values
nothex values.  

See: http://www.postgresql.org/docs/8.2/static/datatype-binary.html

INSERT INTO "FUND_ASSET_DTO_BINARY"
("fundAssetDTOBinaryID', OBJ_VERSION, "binaryFundAssetDTO")
VALUES
(1, 0, \254\355\00 ... )

Btw: are you sure you want to use case-sensitive table and column names? This usually causes more trouble than it's
worth.But that's just my opinion.

And you need some quotes, too.

It might make for less change in the application if you use decode() to
convert a hex string to bytea, a la

    decode('ACED0005737200286...', 'hex')
