GMTAlexSQLForumshttp://www.sqlservercentral.com/Forums/Topic820692-146-1.aspx[b]Requirement:[/b]A SQL Script that can be used to generate the 'Update' Statements for a Table which has dataI found a superb piece of code @ http://www.keylimetie.com/blog/2009/3/24/sql-server-2005-script-to-generate-insert-statements for a 'Insert Statement Generator'. Well, call me lazy or a person who would not want to re-invent the wheel, Can anyone post their code if any that can generate Update statements for any given table.I do not want to specify the Primary Key Name or the Primary Key Value. The script should be able to pull the primary key and get the value from the existing rows. ;-)I have started working on this already, but thought it would be a good idea to post this in this intellectual forum! Thanks for your time to read through this. :-)[b]To be more specific:[/b]If I have a table with this structureCREATE TABLE [Address]( [AddressID] [int] IDENTITY(1,1) NOT FOR REPLICATION NOT NULL, [AddressLine1] [nvarchar](60) NOT NULL, [AddressLine2] [nvarchar](60) NULL, [City] [nvarchar](30) NOT NULL, CONSTRAINT [PK_Address_AddressID] PRIMARY KEY CLUSTERED ( [AddressID] ASC))And it has the following dataINSERT INTO Address( [AddressID], [AddressLine1], [AddressLine2], [City])SELECT 32506, '5407 Cougar Way', ' ', 'Seattle'Go INSERT INTO Address( [AddressID], [AddressLine1], [AddressLine2], [City])SELECT 32507, '2284 Azalea Avenue', ' ', 'Bellevue'Go INSERT INTO Address( [AddressID], [AddressLine1], [AddressLine2], [City])SELECT 32508, '108 Lakeside Court', ' ', 'Bellevue'Go INSERT INTO Address( [AddressID], [AddressLine1], [AddressLine2], [City])SELECT 32509, '535 Greendell Pl', ' ', 'Sammamish'[b]This script should return the following output:[/b]Update Address SET AddressLine1 = '5407 Cougar Way',AddressLine2 = ' ',City = 'Seattle',WHERE = 32506 Update Address SETAddressLine1 = '2284 Azalea Avenue',AddressLine2 = ' ',City = 'Bellevue',WHERE = 32507 Update Address SET AddressLine1 = '108 Lakeside Court',AddressLine2 = ' ',City = 'Bellevue',WHERE = 32508 Update Address SET AddressLine1 = '535 Greendell Pl',AddressLine2 = ' ',City = 'Sammamish',WHERE = 32509[b]In case you have more time to read and guessing why I need this script?[/b]My current project is a SQL Server Migration project. A new version of the Application (V2) has been released and we are migrating data from the older version (V1) to (V2). The table schema has changed considerably between these 2 versions and we have a table where we maintain the Column Mapping details and couple of scripts that can dynamically generate the V2 Table Schema, Views and the Migration script also.There is a [b]special requirement[/b] :w00t: where we are doing a 2-way Synchronization between 2 databases which have totally different structure - V1-->V2 and V2-->V1. We are right now implementing it by capturing all changes by triggers and logging it in to a Staging table and then a job runs which pushes the data either ways.After all these hard work, we are at the point of testing this Synchronization and we need a automated way to Generate Test Data.Since this is a 2 way Synch, we have a couple of test scenarios like the followingInsert rows into V1 tables Insert a row into a table. Update this row by changing the values of one or more columnsInsert a row into a table. Follow this up with a delete of the same rowUpdate an existing row in the V1 tableUpdate an existing row followed by a second updateUpdate an existing row followed by a deleteDelete an existing row from V1Delete an existing row from V1 followed by an insert with the same PK valueThe above 8 should result in these below 8The rows should get inserted in the corresponding V2 tablesThe row in V2 should reflect the changes done in the update statementThe row should not appear in V2The changes should get reflected in V2The changes of the second update should get reflected in V2The row should be deleted from V2The row should get deleted from V2The new row should get inserted into V2 and the old row should not be presentThanksKayalWed, 18 Nov 2009 03:59:52 GMTKayal
