How can I generate an INSERT script for an existing SQL Server table that includes all stored rows?

Yes, but you'll need to run it at the database level.

Right-click the database in SSMS, select "Tasks", "Generate Scripts...". As you work through, you'll get to a "Scripting Options" section. Click on "Advanced", and in the list that pops up, where it says "Types of data to script", you've got the option to select Data and/or Schema.

This script generates insert statements of your existing data. This is a stored procedure which you need to run once and then it is tailor made for you.

I tried to find this kind of stuff for a while but wasn't satisfied with the results, so I wrote this stored procedure.

Example:

Exec [dbo].[INS]  'Dbo.test where 1=1'

(1) Here dbo is schema and test is tablename and 1=1 is condition.

Exec [dbo].[INS]  'Dbo.test where name =''neeraj''' * for string

(2) Here dbo is schema and test is tablename and name='neeraj' is condition.

Here is the stored procedure

/*
Authore : neeraj prasad sharma (please dont remove this :))
Example (1) Exec [dbo].[INS]  'Dbo.test where 1=1'
        (2) Exec [dbo].[INS]  'Dbo.test where name =''neeraj''' * for string

here Dbo is schema and test is tablename and 1=1 is condition
