Here is error when any changes on table. 1328 - Incorrect number of FETCH variables

Thanks for advance

That is simply a syntax error and the message you are getting is telling you exactly what is wrong.

In your cursor definition you are selecting out many columns (all from each of the three tables) and in the fetch statement you are only referring to a single column (pulling the first column from the cursor into the variable retribAn). The number of variables you fetch from the cursor needs to match the number the cursor returns.
