Please refer to following tutorial for more examples on SQL Concatenation using FOR XML PATH() method. The below script gets a random number of BookAuthors rows and sql concatenate AuthorId column values using comma as delimiter character. And copy and paste the below sql statements into the "External Source of SQL Data" query screen. Select the same database since both tables are on the same database. Realistic, simulated data for testing, development and prototypes. Use the sample data to iterate your app and blueprints. Then click the "Edit" button in order to select the database and edit the t-sql script. Use the Data Generator utility to create Blueprints and then generate. It has pulled in the file, and for each row of the column has. Then simply select the File List generator and specify this file: Figure 6. When you select " SQL Statement - Reads data from SELECT statement" from the list the Column generation settings will change as shown in the below screen-shot from the SQL Server tool. If you’d like to try it for yourself, download the file, and place it in C:\Program Files (x86)\Red Gate\SQL Data Generator 3\Config, along with all the built-in files. We can customize the test data generation by using the " SQL Select Statement" instead of the " RegexpGenerator" default for varchar, nvarchar data types. I had to customize the test data generation so that the process should concatenate the AuthorId column values within the BookAuthors table in a random manner for each test data record for the Books table. I had to customize the test data generation process somehow. Since the Authors column in Books table has data type varchar it does not produce logical values if I use the SQL Data Generator tool to populate the row columns with random string values. We can just hope creating test data for SQL Server is not so difficult using this tool from Red-Gate. I know that is not a good database desing but we have such tables in our databases. But I will copy screenshots displaying sample data from both sql database tables which will help you visualize the database design.Īs you see, in the Books table in Authors column I keep ID's as comma seperated. The tables will have a one to many relationship where an author can have multiple books. The first table will store information about imaginary authors and the second table will store information about imaginary books. Here is the case which I require test data.īooks sql table has a column Authors where the authors of the book is kept as comma seperated values of the author's Id value in the Authors sql table. We will create a dummy library database with two tables: tblAuthors and tblBooks.
