Concatenate rows into one row in sql with serial number

To concatenate the Name columns into one column with serial numbers in SQL, you can use the ROW_NUMBER() function along with FOR XML PATH to achieve the desired output. Here is how you can do it:

SELECT
    STUFF((SELECT ' (' + CAST(ROW_NUMBER() OVER (ORDER BY Name) AS VARCHAR) + ') ' + Name
           FROM Employees
           FOR XML PATH('')), 1, 1, '') AS Name
FROM Employees;

In this SQL query:

1. The ROW_NUMBER() function is used to generate serial numbers based on the order of the Name column.

2. The FOR XML PATH('') function is used to concatenate the rows into a single string.

3. The STUFF() function is used to remove the first character (which will be a space) from the concatenated string.

This query will give you the concatenated Name column with serial numbers as specified in your desired output.

For the Father Name column, you can apply a similar approach:

SELECT
    STUFF((SELECT ' (' + CAST(ROW_NUMBER() OVER (ORDER BY FatherName) AS VARCHAR) + ') ' + FatherName
           FROM Employees
           FOR XML PATH('')), 1, 1, '') AS FatherName
FROM Employees;

You can adjust the column names (Name, FatherName) based on your actual table schema. This SQL query will concatenate the Father Name column with corresponding serial numbers just like you've described.
