When writing the end routine today, You need to split one record into two, checkCodePass. However, the following error is reported during execution: during loading, there was a key violation. You tried to save more than one.
DataRecord with the same semantic key.
I obviously changed the copied data to a key value, which cannot be repeated. So I set the breakpoint and re-enter the debugging. The key value of the newly added record is different. However, I found that the second column has a record field, but I did not pay attention to it, I never know what to do. At the beginning, according to the error message, I checked the semantic key, and the display was gray. No modification is allowed. Finally, we found that record is the real boss, and it cannot be repeated. Therefore, we set a variable, re-copied the new data, and finally passed. I haven't found any record information yet. I don't know what it is.
