在既有的系統上新增功能時，我們常常會在開發環境進行測試，這時會在我們的測試資料庫產生新的資料表，甚至在既有的資料表上設定一些資料，而等到開發測試完成要正式發佈到正式環境時，新的資料表可以利用SQL的產生指令碼方式來產生SQL Script，但是資料就沒辦法用這個方式來產生，特別是在既有的資料表上所增加的資料。

所幸，從網路上發現保哥已經幫我們找到了這個問題的解答：

原作者網站有執行範例： Procedure to script your data (to generate INSERT statements from the existing data)

SQL StoreProcedure程式碼：

All rights reserved.) Purpose: To generate INSERT statements from existing data. These INSERTS can be executed to regenerate the data at some other location. This procedure is also useful to create a database setup, where in you can script your data along with your table definitions.

Results can be unpredictable with huge text columns or SQL Server 2000's sql_variant data types Whenever possible, Use @include_column_list parameter to ommit column list in the INSERT statement, for better results IMPORTANT: This procedure is not tested with internation data (Extended characters or Unicode). If needed you might want to convert the datatypes of character variables in this procedure to their respective unicode counterparts like nchar and nvarchar ALSO NOTE THAT THIS PROCEDURE IS NOT UPDATED TO WORK WITH NEW DATA TYPES INTRODUCED IN SQL SERVER 2005 / YUKON Example 1: To generate INSERT statements for table 'titles': EXEC sp_generate_inserts 'titles' Example 2: To ommit the column list in the INSERT statement: (Column list is included by default) IMPORTANT: If you have too many columns, you are advised to ommit column list, as shown below, to avoid erroneous results EXEC sp_generate_inserts 'titles', @include_column_list = 0 Example 3: To generate INSERT statements for 'titlesCopy' table from 'titles' table: EXEC sp_generate_inserts 'titles', 'titlesCopy' Example 4: To generate INSERT statements for 'titles' table for only those titles which contain the word 'Computer' in them: NOTE: Do not complicate the FROM or WHERE clause here. It's assumed that you are good with T-SQL if you are using this parameter EXEC sp_generate_inserts 'titles', @from = "from titles where title like '%Computer%'" Example 5: To specify that you want to include TIMESTAMP column's data as well in the INSERT statement: (By default TIMESTAMP column's data is not scripted) EXEC sp_generate_inserts 'titles', @include_timestamp = 1 Example 6: To print the debug information: EXEC sp_generate_inserts 'titles', @debug_mode = 1 Example 7: If you are not the owner of the table, use @owner parameter to specify the owner name To use this option, you must have SELECT permissions on that table EXEC sp_generate_inserts Nickstable, @owner = 'Nick' Example 8: To generate INSERT statements for the rest of the columns excluding images When using this otion, DO NOT set @include_column_list parameter to 0. EXEC sp_generate_inserts imgtable, @ommit_images = 1 Example 9: To generate INSERT statements excluding (ommiting) IDENTITY columns: (By default IDENTITY columns are included in the INSERT statement) EXEC sp_generate_inserts mytable, @ommit_identity = 1 Example 10: To generate INSERT statements for the TOP 10 rows in the table: EXEC sp_generate_inserts mytable, @top = 10 Example 11: To generate INSERT statements with only those columns you want: EXEC sp_generate_inserts titles, @cols_to_include = "'title','title_id','au_id'" Example 12: To generate INSERT statements by omitting certain columns: EXEC sp_generate_inserts titles, @cols_to_exclude = "'title','title_id','au_id'" Example 13: To avoid checking the foreign key constraints while loading data with INSERT statements: EXEC sp_generate_inserts titles, @disable_constraints = 1 Example 14: To exclude computed columns from the INSERT statement: EXEC sp_generate_inserts MyTable, @ommit_computed_cols = 1 ***********************************************************************************************************/ SET NOCOUNT ON --Making sure user only uses either @cols_to_include or @cols_to_exclude IF ((@cols_to_include IS NOT NULL) AND (@cols_to_exclude IS NOT NULL)) BEGIN RAISERROR('Use either @cols_to_include or @cols_to_exclude.
