Sql update column name

Renaming a column won't automatically rename references to that column. You must modify any objects that reference the renamed column manually. For example, if you rename a table column and that column is referenced in a trigger, you must modify the trigger to reflect the new column name.

Use sys. You can also change the name of a column in the Column Properties tab. Select the column whose name you want to change and type a new value for Name. The following example renames the column ErrorTime in the table dbo. Maybe you messed up the name from the start, or your team decided the name needs to change for business reasons.

Luckily, the process to change a column name is not too difficult in SQL Server. After all, you are, in fact, altering the column if you rename it, right? This is the name of the column we want to change. When we specify the column name, we need to do so using the two part identifier. That means we include the name of the table too. The table is Sales , and the column within that table the column we want to change is EmplID. When we specify a value for this parameter, we wrap it around single quotes.

This is of course the new name we want to give our column. When we specify the new name, we do not use the two part identifier. We wrap the value around single quotes, too. The last parameter is the type of object we want to change. Like the other parameters, notice this is also wrapped around single quotes. However, it is a good answer for anyone using Microsoft's system.
