How Can I Handle SQL Column Names That Are Also Keywords?

Handling column names similar to SQL keywords

In SQL programming, encountering column names that are the same as SQL keywords can pose challenges. This occurs, for example, when processing a column named "from".

To avoid SQL Server confusion, such situations must be handled properly.

Solution:

The preferred solution is to wrap the column name in square brackets, effectively escaping it. For example, "from" becomes "[from]".

select [from] from TableName;

Additionally, you can use table name prefixes to differentiate column names:

select table.[from] from table;

Influence:

By using these techniques, you can safely use column names similar to keywords without causing ambiguity in SQL queries.
