Create and update table definitions
This topic shows how to programmatically create a custom user-owned table called Bank Account and add four different types of columns to it.
You can also create organization-owned custom tables. More information: Table ownership. You can download the sample from here.
Note
Unsure about entity vs. table? See Developers: Understand terminology in Microsoft Dataverse.
How to run this sample
- Download or clone the Samples repo so that you have a local copy.
- (Optional) Edit the cds/App.config file to define a connection string specifying the Microsoft Dataverse instance you want to connect to.
- Open the sample solution in Visual Studio and press F5 to run the sample. After you specify a connection string in cds/App.config, any sample you run will use that connection information.
If you do not specify a connection string in cds/App.config file, a dialog will open each time you run the sample and you will need to enter information about which Dataverse instance you want to connect to and which credentials you want to use. This dialog will cache previous connections so that you can choose a previously used connection.
Those samples in this repo that require a connection to a Dataverse instance to run will include a linked reference to the cds/App.config file.
What this sample does
The CreateEntityRequest message is intended to be used in a scenario where it contains the data that is needed to create a custom table, and optionally, to add it to a specified unmanaged solution.
How this sample works
In order to simulate the scenario described in What this sample does, the sample will do the following:
Setup
Checks for the current version of the org.
Demonstrate
- The
createrequestmethod creates the custom table. - The
Entitymethod is used to define the table. - The
StringAttributeMetadatamethod defines the primary column of the table. - The
CreateBankNameAttributeRequestmethod creates a string column to the table. - The
CreateBalanceAttributeRequestmethod creates a money column to the table. - The
CreateCheckedDateRequestmethod creates a DateTime column to the table.
Clean up
Display an option to delete the records created in the Setup. The deletion is optional in case you want to examine the tables and data created by the sample. You can manually delete the records to achieve the same result.
