Answer 2

It is necessary to make a query to the SQL database in python, to a certain table that has the same names in one column. The goal is to select those rows that use the same name in the same column. But, the name is not known. That is, a query for strings with the same name must be in an abstract form.

Answer 3

The SQL inquiry: SELECT * FROM table WHERE column_name=same_name

Answer 4

To select rows from a SQL table where the same name appears more than once in a specific column (like name), you can use a GROUP BY clause combined with HAVING COUNT(*) > 1. This helps identify duplicate values. Once the duplicate names are identified, you use a subquery to select all rows that match those names.

In Python, you can run this SQL query using the sqlite3 library or any database connector. First, connect to your database, then execute the query, and fetch the results.

If you're using pandas, you can read the whole table into a Data Frame and then filter rows where the name column has duplicates by using the duplicated() function with keep=False, which returns all rows that share the same name.

This approach helps in cleaning, analyzing, or investigating duplicate data entries in a table based on any column.
