Re: [sqlite] sth more then step()

If you call this function 10 times it will skip over 10 rows. Then you use the sqlite3_column_*() API functins to read the data from the rows you are interested in. There is no way to skip 10 records with a single call (to the best of my knowledge). Why I have to use LIMIT in SELECT when I need use only OFFSET ? Because thats how it is defined by the SQL language. ;-) Actually it's not part of the standard, but it is a common extension supported by several RDMS. If you don't want to limit the number of rows returned then pass a negative limit value. For example: SELECT * FROM table LIMIT -1 OFFSET 10 will return all rows of the table after skipping the first 10. HTH Dennis Cote

You can call it anytime to skip to the next row of the result set. If you want to skip the first 10 rows simply call it 10 times then start looking at your results using the sqlite3_column_*() API functions.
