How Do I Handle SQL Column Names That Conflict with Keywords?

Resolving Conflicts Between SQL Column Names and Reserved Keywords

Using SQL column names that mimic reserved keywords can cause database processing errors. For example, a column named "from" clashes with the SQL keyword "FROM".

The best solution is to enclose the column name in square brackets []. Instead of SELECT from FROM TableName, use SELECT [from] FROM TableName. This clearly distinguishes the column from the keyword.

Alternatively, especially when querying multiple tables, explicitly specify the table name: SELECT table.[from] FROM table. Both methods ensure unambiguous queries and prevent execution errors.
