Concurrency error que update

[adolfofb]

Hi.

I get a concurrency error when I try to update with the PsqlDataAdapter if the original database row has a null value.

Help, please...

Problem is that you try to use column name "user" without qouting symbols. "user" is PostgreSQL server keyword. You can solve this problem in to ways:
1) rename column user
2) set PgSqlCommandBuilder.Quoted property to true
