When writing or editing SQL scripts, small features in SQL Server Management Studio can make a huge difference in productivity. One of the most overlooked tools is Block Mode Select. Many developers never realize how much time it can save until they start using it.
Block Mode Select allows you to select text in a vertical block rather than the standard horizontal selection. By holding down ALT and SHIFT while highlighting, you can select and edit entire columns of code at once. This makes it incredibly useful for working with repetitive SQL statements, aligning code, or making bulk edits across multiple lines simultaneously.
Here’s a short video on Block Mode Select
For example, imagine you have a dozen INSERT statements that all need changes to the delivery service field. Instead of editing each line individually, you can block select that column of text and update them all at once.
You can also use it to quickly change text case with Control Shift U for uppercase or Control Shift L for lowercase, keeping SQL keywords consistently formatted.
Block Mode Select also comes in handy when restructuring code. Need to move a column name in an INSERT list? Use block select to grab it across multiple lines, cut it out, and paste it in the right position. Tasks that might take minutes by editing line by line can be done in seconds.
Once you get comfortable with Block Mode Select, you’ll find yourself reaching for it often. It’s one of those hidden gems in SSMS that can transform tedious edits into quick, precise adjustments. Combine it with familiar shortcuts like Control Z for undo, and you’ll be coding faster, cleaner, and with less frustration.
