Betreff: [sqlite] Run non-data producing statement just once to test UDF

Say I have a UDF called AddOne in a statement like this:

update table1 set field1 = AddOne(field1)

and say the table table1 has some million rows.

Now I want to test this statement to test the UDF but I want to do this for 
only one row.
How do I do this?

limit 1 only applies to data producing statements. Adding a where clause, say 
where rowid = 1 is a bit tricky (all this has to be done in code) and there may 
not be a rowid of 1 and I can't do a sqlite3_step as that would run for all the 
rows.
There is no such problem with select statements as I can just run one 
sqlite3_step and just fetch no data and do a sqlite3_reset.

Any suggestions?
