(Sql Server) Sql created by the conventional data table the Insert statement

Before, in Codeproject Sql statement stored procedures published an article about creating Insert with the existing data in the table, and today it moved here, note that this stored procedure only applies to SQL SERVER.

Introduction

Some times you want to export Sql script of some existing records in the table so that you can insert the data into another database table is similar. There are many ways to do now, I will share with you a stored procedure to achieve it together. I hope you help.

Code

First, create the following named [dbo] in your SQL Server databases. [Sp_CreateInsertScript] stored procedures

[dbo].[sp_CreateInsertScript] content:

-- Description: Generat the insert sql script according to the data in the specified table.
--              It does not support the columns with timestamp,text,image.
-- Demo : exec sp_CreateInsertScript '[dbo].[Country]','[continent_name]=''North America'''
-- Change History:
--         1.2016-03-06 Created and published
--         2.2016-03-08 Based on Mike's suggestions, I optimized the codes
--         3.2019-03-09 1)Add code lines to avoid error when @con is empty string
--                      2)Based on Lukas Macedo's suggetstions, add surrounding brackets for column name
--                      3)Simplify WHEN...CASE

Examples

Down, I give an example to help you understand how to use it, assuming there are tables Country (country) in your database, you want SQL statement to insert some data in this table record, the record is a column Filterscontinent_name（洲名）的值为North America的记录。表的创建脚本如下：

CREATE TABLE [dbo].[Country](
    [geoname_id] [varchar](50) NULL,
    [locale_code] [varchar](50) NULL,
    [continent_code] [varchar](50) NULL,
    [continent_name] [varchar](50) NULL,
    [country_iso_code] [varchar](50) NULL,
    [country_name] [varchar](50) NULL
) ON [PRIMARY]

Down by calling a stored procedure you created, with the following statement is executed in order to generate the SQL you want to insert (INSERT) statement. Call to execute the script as follows:

exec sp_CreateInsertScript '[dbo].[Country]','[continent_name]=''North America'''

After execution, you will get the results you want, the screenshot below shows my computer.

Now, you can copy these results or to maintain output is a query or a text file by right-click menu option in order to use you down. Thanks!
