postgresql remove duplicates is a command that helps me remove duplicate rows from my table. It is a database extension.
I’ve had a bad day. I have a dozen accounts on my Google Apps account that have the same name, but I only want to delete two of them.
We don’t get to delete duplicates, but we can search for duplicates. And we can delete them, since we can find the duplicates.
It can find duplicates, but it can also find non-duplicate rows.
Postgres is a database that allows you to search on your own, and it has a bunch of special features that let you do that. Postgres is built on top of PostgreSQL and relies on two dedicated databases. First, it’s much more than just a database, it’s a database for your work. Second, it has data retrieval capabilities that let you search on your own, and let you save it for later. This means you can actually search for duplicate records in the database.
For the curious, Postgres is actually rather small compared to many other database-based databases, but it has a huge selection of features and a very large database of data. Most of the features are just to access your own data.
The thing that makes Postgres special is its ability to handle duplicate records well. This means that you can query data in your database to find out which records are the same or even whether they exist at all. This allows you to perform complex queries that, in other databases, would take days to run.
The main problem with Postgres is it can’t deal well with duplicates. Even though it is designed to handle duplicate records, Postgres doesn’t always handle them correctly. This means that if a user tries to run a query that doesn’t handle duplicates correctly, Postgres won’t let them. This makes it difficult to use Postgres for queries that don’t require duplicate records.
We had a few clients asking us about this recently. One asked for the ability to drop records that have a duplicate key in the same table. Another asked for the ability to have tables with the same columns, but different data. And of course there was the client that wanted to have their table have multiple indexes on the same column. I can sympathize with all of these clients, because they are all using Postgres, and we do work with it.
It’s all very well and good to have the ability to drop duplicate rows, but that doesn’t remove rows from the table that have duplicate keys. The database must be able to handle both situations and that’s what Postgres can do. The table that doesn’t have a unique key is a candidate for elimination. In Postgres it’s called ‘orphan tables.
