How Can I Exclude a Column from a SELECT * Query in SQL Without Manually Listing All Others?

* How to exclude table columns using SELECT [except columnA] FROM tableA without manually listing other columns? **

In SQL, the SELECT statement is usually used to retrieve data from a database table. You can use the wildcard character to select all columns in a table with the SELECT syntax. However, in some cases, you may want to exclude specific columns without manually specifying every other column.

One way to achieve this is to create a temporary table. This method includes:

1. Create a temporary table: Insert all data from the original table into the temporary table using the INTO operator:

   <code class="language-sql"> SELECT * INTO #TempTable
    FROM YourTable</code>

2. Remove unnecessary columns: Next, delete the columns you want to exclude from the temporary table:

   <code class="language-sql"> ALTER TABLE #TempTable
    DROP COLUMN ColumnToDrop</code>

3. Retrieve the results and delete the temporary table: Finally, retrieve the required data from the temporary table and delete it when finished:

   <code class="language-sql"> SELECT * FROM #TempTable
    DROP TABLE #TempTable</code>

This method allows you to exclude columns without manually listing all other columns, saving time and simplifying maintenance when the table structure changes.
