What is the best way to auto-generate INSERT statements for a SQL Server table?
We are writing a new application, and while testing, we will need a bunch of dummy data. I\'ve added that data by using MS Access to dump excel files into the relevant table
-
I have also researched lot on this, but I could not get the concrete solution for this. Currently the approach I follow is copy the contents in excel from SQL Server Managment studio and then import the data into Oracle-TOAD and then generate the insert statements

There are many good scripts above for generating insert statements, but I attempted one of my own to make it as user friendly as possible and to also be able to do UPDATE statements. + package the result ready for .sql files that can be stored by date.
It takes as input your normal SELECT statement with WHERE clause, then outputs a list of Insert statements and update statements. Together they form a sort of IF NOT EXISTS () INSERT ELSE UPDATE It is handy too when there are non-updatable columns that need exclusion from the final INSERT/UPDATE statement.
Another thing that below script can do is: it can even handle INNER JOINs with other tables as input statement for the stored proc. It can be handy as a poor man's Release management tool that sits right at your finger tips where you are typing the sql SELECT statements all day.

It is made ot be simple but fast and powerfull. As always => power is nothing without control, so check before you execute. Its power sits also in the fact that you can make insert statements, so combined gives you a "IF NOT EXISTS() INSERT " capability. The scripts work were there are primary keys or identity columns on table you want to update (/ or make inserts for). It will also works when no primary keys / identity column exist(s) and you define them yourselve. But then be carefull (duplicate hits can occur). When the table has a primary key it will always be used. The script works with a real temporary table, made on the fly (APPROPRIATE RIGHTS needed), to put the values inside from the script, then add 3 columns for constructing the "insert into tableX (...) values ()" , and the 2 update statement. We work with temporary structures like "where columnname = {Columnname}" and then later do the update on that temptable for the columns values found on that same line. example "where columnname = {Columnname}" for birthdate becomes "where birthdate = {birthdate}" an then we find the birthdate value on that line inside the temp table. So then the statement becomes "where birthdate = {19800417}" Enjoy releasing scripts as of now... by Pieter van Nederkassel - freeware "CC BY-SA" (+use at own risk) */ IF OBJECT_ID('tempdb..#ignore','U') IS NOT NULL DROP TABLE #ignore DECLARE @stringsplit_table TABLE (col nvarchar(255), dtype nvarchar(255)) -- table to store the primary keys or identity key DECLARE @PK_condition nvarchar(512), -- placeholder for WHERE pk_field1 = pk_value1 AND pk_field2 = pk_value2 AND ... @pkstring NVARCHAR(512), -- sting to store the primary keys or the idendity key @table_name nvarchar(512), -- (left) table name, including schema @table_N_where_clause nvarchar(max), -- tablename @table_alias nvarchar(512), -- holds the (left) table alias if one available, else @table_name @table_schema NVARCHAR(30), -- schema of @table_name @update_list1 NVARCHAR(MAX), -- placeholder for SET fields section of update @update_list2 NVARCHAR(MAX), -- placeholder for SET fields section of update value comming from other tables in the join, other than the main table to update => updateof base table possible with inner join @list_all_cols BIT = 0, -- placeholder for values for the insert into table VALUES command @select_list NVARCHAR(MAX), -- placeholder for SELECT fields of (left) table @COLUMN_NAME NVARCHAR(255), -- will hold column names of the (left) table @sql NVARCHAR(MAX), -- sql statement variable @getdate NVARCHAR(17), -- transform getdate() to YYYYMMDDHHMMSSMMM @tmp_table NVARCHAR(255), -- will hold the name of a physical temp table @pk_separator NVARCHAR(1), -- separator used in @PK_COLUMN_NAME if provided (only checking obvious ones ,;|-) @COLUMN_NAME_DATA_TYPE NVARCHAR(100), -- needed for insert statements to convert to right text string @own_pk BIT = 0 -- check if table has PK (0) or if provided PK will be used (1) set @ignore_field_input=replace(replace(replace(@ignore_field_input,' ',''),'[',''),']','') set @PK_COLUMN_NAME= replace(replace(replace(@PK_COLUMN_NAME, ' ',''),'[',''),']','') -- first we remove all linefeeds from the user query set @fullquery=replace(replace(replace(@fullquery,char(10),''),char(13),' '),' ',' ') set @table_N_where_clause=@fullquery if charindex ('order by' , @table_N_where_clause) > 0 print ' WARNING: ORDER BY NOT ALLOWED IN UPDATE ...' if @PK_COLUMN_NAME <> '' select ' WARNING: IF you select your own primary keys, make double sure before doing the update statements below!!

INSERT INTO Queues([QueueName], [iSort]) SELECT 'WD: Auto Capture', '10' UNION SELECT 'Car/Lar', '11' UNION SELECT 'Scan Line', '21' UNION SELECT 'OCR', '22' UNION SELECT 'Dynamic Template', '23' UNION SELECT 'Fix MICR', '41' UNION SELECT 'Fix MICR (Supervisor)', '42' UNION SELECT 'Foreign MICR', '43' UNION ...讨论(0) -
We use this stored procedure - it allows you to target specific tables, and use where clauses. You can find the text here.
For example, it lets you do this:
EXEC sp_generate_inserts 'titles'

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 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.

GenerateData is an amazing tool for this. It's also very easy to make tweaks to it because the source code is available to you. A few nice features:
- Name generator for peoples names and places
- Ability to save Generation profile (after it is downloaded and set up locally)
- Ability to customize and manipulate the generation through scripts
- Many different outputs (CSV, Javascript, JSON, etc.) for the data (in case you need to test the set in different environments and want to skip the database access)
- Free. But consider donating if you find the software useful :).
