Data view cannot display data

Found it, wait a minute, I execute it

After execution is complete, no data is displayed

That is the problem of your where condition. Are the two tables related through the fields you wrote, and the condition is wrong, there must be no data ...
WHERE ("contract". "Gsxm" = "project". "Xmbm")

xmbm is the primary key of the project, do the gsxm and xmbm fields need to be set to the contract's foreign key?

unkmass

Having a primary foreign key and whether to set the relationship are two different things, see if the xmbm and gsxm data in the two tables are the same

Ok, got it, i double checked, thanks again
