A Cursor with the name already exists

 While executing cursor inside Stored procedure it is throwing error:

A cursor with the name 'cursorName' already exists

declare cursorName CURSOR FOR
        select ...;

    open cursorName;

        Body of cursor...
        close cursorName;
        deallocate cursorName;

This is because we are using global cursor that will be defined each time you are calling this procedure and give you the same error.

Define a local cursor. Just put the keyword LOCAL after CURSOR

This will look like

declare cursorName CURSOR LOCAL FOR
...
This will resolve the issue.
