Обсуждение: pgAdmin vs SQL Server Enterprise Manager
I am working at a company that has been using MS SQL Server, and we are going to be switching over to postgresql next week. (Getting off of Windows will be a relief!) I am very familiar with SQL Server's "Enterprise Manager", which is their GUI for accessing the db. I have been acquaintingmyself with pgAdmin. There are a number of things that I really like about pgAdmin, but there are a few thingsthat SQL Server Enterprise manager can do, and it's not clear to me if pgAdmin can do them. Can anyone let me know how the following things are done in the postgres world? 1) With SQL Server Enterprise Manager, I can change a column's type. For example, I can change an int column to a float,and SQL Server automatically converts all of the int data to floating point data. 2) With SQL Server Enterprise Manager, I can copy and paste rows. There are two scenarios: 2a) Suppose I have a table that has some primary key, and it has a large number of non-null columns. Inserting a row canbe tedious because I have to specify all the non-null values. What I often want to do is to duplicate a row, change itsprimary key, and perhaps modify 1 or 2 of its other columns. With SQL Server Enterprise Manager, I can copy a row intoa "new row" buffer, modify its primary key to ensure uniqueness, optionally modify 1 or 2 other columns, and paste theresult into the table. 2b) Suppose I have two or more tables that have identical schemas (column names and types, primary key). I want to copya set of rows from one table to another. (I've already verified that there will be no primary key conflicts.) WithSQL Server Enterprise Manager, I can copy a set of rows from one table and paste them into another table. Any help would be appreciated! -Mike Wertheim
Dear Mike, These are pgAdmin3 rather specific questions. I am forwarding your questions to pgAdmin-support list. You can register the support list from: http://www.pgadmin.org/pgadmin3/support.php#support_list Best regards, Jean-Michel > I am working at a company that has been using MS SQL Server, and we are > going to be switching over to postgresql next week.

There are a number of things that I really like about pgAdmin, but there are a few thingsthat SQL Server Enterprise manager can do, and it's not clear to me if pgAdmin can do them. Unlike EM for SQL Server, there is no vendor developed and distributed gui client for postgresql. While PgAdmin is probably the first choice, there are a lot other tools for graphical manipulating postgresql schema and data. Some of them are windows only, others are available on different platforms too. See gborg or google for a reference (There are even sposored links in google if you type in something with "postgresql") > Can anyone let me know how the following things are done in the postgres world? > > > 1) With SQL Server Enterprise Manager, I can change a column's type.

And as it turns out, some things (like copy table data between identical tables) is even simpler with the statement instead of copy and paste. Regards Tino Wildenhain
