Table and column GUIDs
Overview
A GUID is a globally unique identifier, formatted as a 128-bit text string, that represents a unique identification. Both Cinchy Tables and Columns have a GUID.
This feature is particularly useful when deploying between Cinchy instances.
For example, in a model deployment, you must have matching GUIDs on your columns in order for them to properly load between environment A and environment B. There might be times when these GUIDs don’t automatically match, however, such as if you manually added a new column to environment B and also manually added it to environment A.
In this case, the two columns would have different GUIDs, and the model deployment would fail. With this new feature, however, you can match up conflicting GUIDs to properly load your model.
1. Viewing and Editing GUIDs
You have the ability to display and edit these table and column GUIDs within the Design Table screen.
Table GUIDs musts be unique to your specified environment.
Column GUIDs must be unique to the table.
Table GUIDs can be found under Design Table > Info > GUID (Image 1).
Click on the pencil icon to edit the GUID.
GUIDs must adhere to supported formats for Cinchy.
32 hexadecimal (base-16) digits.
Displayed in five groups, separated by hyphens.
The groups take the form of 8-4-4-4-12 characters, for a total of 36 characters (32 hexadecimal characters and 4 hyphens).
Example: 123e4567-e89b-12d3-a456-426614174000
Warning: Changing the value may have damaging effects, proceed with caution.
