#Azure data studio add column to table code#
Using the code in Listing 3, we populate a new table with 1000 rows. Listing 2: Add ManagingDirector Column to Empty TableĪlter table ntab add ManagingDirector varchar(50) Įxec sp_columns ntab Figure 1: ManagingDirector Column Added We generated this metadata about our table with the sp_columns stored procedure. The result is a five-column table, as shown in Figure 1. To add a single column to the ntab table, we execute the code provided in Listing 2. To begin our short set of experiments, let’s create a small table with four columns containing basic information about some company: - Listing 1: Create New Table ntab Particularly, it happens when there are updates for an application, and they demand adding new columns.
