QUESTION

Can you compare the output of a scalar function with a scalar in a check statement? SQL

Asked 2020-Dec-01 at 18:50

I want to compare the output of a scalar function with a scalar value in a CHECK statement when creating a table, but it doesn't seem to do the right comparisons. I want the check statement to be "checked" if the scalar function returns 1. Is there any way to do this? (The function is called in the last check statement)

The statement runs successfully, and if I run the function out of the CHECK function it returns the right values (0 or 1), but when I insert data that satisfies 1 in the function returned value, errors are returned. This is my code and what I've tried,

Marx,

I see no error with the CHECK statement in your table. See the dbfiddle here; it is working as intended, because the value you are trying to INSERT violates the CHECK statement and will not work.

If you click the link and scroll down, you see that based on the data you provided, there is no way for the function to return 1 for some of these rows. Namely, here is one example that fails:

QUESTION

representive Vertex cycle cover

Asked 2020-Sep-02 at 07:55

This problem may be related to this post.

This problem also asked here but with a different taste.

Consider an (undirected) square graph with a periodic boundary condition. Then find a complete cycle graph with length equal to 4. now I want to assign a unique representative to each cycle from its elements. Therefore in a square graph with n_v vertex i will find n_f=n_v 4-cycles and n_v representative for the cycles. For the square graph, everything is simple. just assign the bottom left vertex of each plaque(4-cycles).

(i just show first 4-cycle)

Now, I want to generalize it for other structures. consider (undirected) kagome graph with proper boundary condition,

(here I just show 3 distinct cycles)

In this case for assigning a vertex to cycles cover, you need three different length cycles. which show by similar color with the assigned vertex. However, now I want to generalize this to other complicated graphs. I want to know is this problem has a name and about its possibility or algorithm. For example, we cannot do it in a triangular graph:

This problem solved here.

I)Let show all faces and vertices by \alpha_i, where i contain vertices and faces.
II) make a graph which relates \alpha_i (from i in face group) to \alpha_j (to j in vertex group), if j(vortex) belong to i(face).
III) find the independent edge set of this graph gives for any vortex a face.

Please see here for additional information.

Install kagome

First build will likely take long time. However, you can cache binaries to hunter-binary-cache or even download binaries from the cache in case someone has already compiled project with the same compiler. To this end, you need to set up two environment variables:. To generate github token follow the instructions. Make sure read:packages and write:packages permissions are granted (step 7 in instructions). This project is can be built with.
