hi Walter Try
INSERT INTO mytable(column2) VALUES (12345) In other words, do not try to insert the column you want to be auto-generated. The database engine will notice that you are inserting only a subset of the columns, and SHOULD use the default values for the missing columns, which would be NULL unless you specified otherwise. In the case of column1 you have specified that the default value would be the auto-incremented value. If your table has a column3 then you should find that is set to NULL by my suggested syntax. I do not have v3 running currently so cannot test it myself, so please report back for the benefit of myself and everyone else whether that works for you or not. I am also interested to know if you find my syntax works on v2.5, if you still have it installed to test it? Please don't go to the trouble of re-installing it just to test it. It is arguable that v3 is correct in rejecting the syntax you have previously used, because it does not make logical sense to tell the database engine to insert a null when you mean something else. The syntax I suggested will be more portable to other db engines because it is closer to the standard. I hope that suggestion proves helpful Warmly River~~ On 19/11/2020, 'Walter R.
