Shuffle – Randomly reorganizes generated data for a specific column.
#Data generator for sql generator#
Which option is presented for a specific generator depends on the generator itself, as some of these are available only for a specific data types: The application automatically recognizes which generators are suited for each column based on the column name and its data type and only these generators will be presented for that specific column.Īll the generators have some partially shared options. Data generationĪpexSQL Generate populates SQL databases with synthetic test data by assigning a generator to each column. In this article, we’ll introduce the tools’ core features, describe the main types of generators, walk you through an example and, finally, cover some advanced features. Once again, for more information, you can visit Have a great day.ApexSQL Generate is a test data generation tool for SQL Server. This is the INSERT statement inserting the 10 rows of data. I'm going to choose the script option so we can see the final product.Īnd there you have it. You can directly run the script now, and you have the option of making it a background process. You can add null values where applicable to give more realistic feel of the data.īut once you have the columns the way you want them, you can either export the data as we talked about in this menu, or we can generate the data now. So obviously, you can't put a date/time in a column that is only accepting small ints. But again, you could choose Refresh here or here.Īnd again, depending on the data type itself, you have limited options as far as the dropdown. I'm going to choose State, and you can see that it was refreshed as soon as I chose the dropdown. So if I select Address and expand out, we can start to do things like put in generated data about city names, or of states, countries, et cetera. So if I choose the dropdown menu and I go all the way up to the top- and start collapsing all of these- we can see that this was under the Personal Information, but this may be more of an address sort of thing. For Name, it's given first name- and that may not necessarily be what we want, especially considering this is a table about location. For Location ID, it's given us an auto increment. So to the rows themselves, what happens in the background when you're choosing Data Generation is, Toad will go out and look at the data types for each one of the columns and then at the name of the column itself and give its best guess on what it thinks the type of data that you were interested in generating. You can see, if I modify the number of rows for this specific table and then hit Refresh, the Preview pane at the bottom will change. So it may be important to create thousands of rows or just a few dozen rows, depending on what you're interested in doing. So now that we have the single object, the first thing that I usually do is look at the number of rows. I could right click, and again choose Data Generator. And I have the production database selected. If we wanted to look at a single table, I could simply come over to the Object Explorer. I will leave all this default for now.Īnd this is for generating, again, data from multiple tables. This allows you to affect some of the script information- as far as running pre and post scripts, check constraints, global variables- as far as setting the default row count for the generation, what to do for invalid data, default file location, et cetera. At the very top, we have a menu that has the file options for saving and opening projects, as well as exporting data. And I will select the database.Īnd now, in the new tab, we have a list of all the different objects associated with the database, and we have the connection information at the top. And again, using the connections that I have, or I could create a new connection here. If I wanted to generate data for an entire database, I could come to File, New, and Data Generator.Īnd that would open up a tab that would allow me to either open an existing project or create a new one by selecting a database. So to generate data, you have a couple of different options. So as you can see, I have Toad for SQL open and I've already made a connection to the database itself.
