DISTINCT can be used for removing duplicate tuples in the query result in SQL

Yes, that's correct. The DISTINCT keyword in SQL is used to return unique or different records in the output of a SELECT statement. It eliminates all the duplicate records from the result set.

Here's a step-by-step breakdown of how to use DISTINCT:

1. SELECT: As usual, we start with the SELECT keyword to specify that we're retrieving data.

2. DISTINCT: Next, we add the DISTINCT keyword right after SELECT. This tells SQL that we want to avoid duplicate records in the columns we're about to specify.

3. Column Names: After DISTINCT, we specify the column names for which we want to see unique values. If you want to select all columns, you can use "*".

   Example: SELECT DISTINCT column1, column2 FROM table_name;

4. FROM: This is used to specify the table from which we want to retrieve data.

So, a complete SQL SELECT statement with DISTINCT could look like this:

SELECT DISTINCT column1, column2 FROM table_name;

This will return all unique combinations of column1 and column2 from table_name. If you want to select distinct values from a single column only, you can specify that column name after DISTINCT.
