Tips ‘N’ Tricks – SSMS – Quickest way to SELECT and Query All Columns from a Table in SQL Server
Most of you, who are working on T-SQL must be knowing that using “SELECT * FROM <<Table>>” syntax is treated as a Bad Practice and instead, using “SELECT <<Column Names>> FROM <<Table>>” syntax is recommended as a Best Practice for various reasons (discussing those is not in scope of this article).
So, to be able to follow the Best Practice, it requires typing in the names of individual columns which is a time-consuming process especially if there are huge number of columns to be specified in the Select List. To overcome this very concern, there is actually a really cool shortcut for specifying the names of the columns in the SELECT statement with just few mouse clicks. Here is how this simple trick works.
I had previously published a tip titled Quickest way to SELECT All Columns from a Table at Just Learned on BeyondRelational.com. It became very popular and I received a great feedback from the community members. In the interest of my blog’s subscribers and visitors, I am going to present that tip here with a couple of visuals as follows.
Say you want to select all the columns from a table, for which you would write a query something like this:
Now, as specified above, we need to replace the asterisk (*) in the above query with the list of all the columns present in DimProduct table. To do this, follow these steps:
- Go to SSMS, Open a new query window, Type SELECT followed by a space on First Line and FROM dbo.DimProduct on the Second Line.
- Go to Object Explorer | Database Containing DimProduct Table | DimProduct Table
- Expand the DimProduct table and click on Columns folder
- Hold the Left Mouse Button and Drag the Columns folder on to the Query Window after SELECT, which will pull all the columns from DimProduct table and place them after the SELECT statement in the query window separated by commas (,) as shown below.
When you drag the Columns folder, All the Columns from DimProduct are placed after the SELECT Clause and before the FROM Clause in the above query window as shown below.
Now, you can make slight formatting changes to suit your needs and if you want, you can even remove some of the columns based on your need (Remember that, removal is always easier than addition when it comes to Coding and hence this approach!).
This is one of my all time favorite tips and I use this almost all the times 🙂
