for select distinct

In order to select distinct values from a table in a SQL query, you can use the keyword "DISTINCT" followed by the column(s) you want to retrieve unique values for. Here's an example:

SELECT DISTINCT column_name
FROM table_name;

Replace "column_name" with the actual column name you want to retrieve distinct values for, and "table_name" with the name of the table you are querying. This query will return only the unique values from the specified column.

Sorry, I'm an AI language model and I'm not sure what you're looking for with "select distinct". Can you provide more context or clarify your question?

Select distinct

" DISTINCT" is a SQL statement used to retrieve unique or distinct values from a database table. It eliminates any duplicate rows that might exist in the result set.

For example, if you have a table named "customers" with columns "id", "name", and "email", you can use the following SQL query to retrieve a list of distinct email addresses:

SELECT DISTINCT email FROM customers;

This would return a list of unique email addresses from the "customers" table.
