Hi, I think this has been discussed before, but I can't find a good solution so I'll post it again to see what people think.
Here's the problem. I have a large number of records in a table, which contains many columns. Hence a large amount of data. I have a SQL query that filters the results by search criteria across many of these columns. I am using a web front end to display paged results. I need to tell the user how many records there are in total, how many pages and which page they are viewing. I would like to use the LIMIT keyword to restrict the result using the two parameters (offset and limit count) so that I do not waste resources loading up 1000's of records just to discard the ones not on the current page. However if LIMIT is added to the SQL, I do not get a count of the records that the SQL select would have produced if I had not limited the query with LIMIT. I could do two selects with the same WHERE restriction, one with SELECT COUNT(*) and the other with SELECT field1, field2, etc but this seems wasteful, especially if the query is expensive in resources. Perhaps a new function could be added to SQLite that returns the record count regardless of any LIMIT applied? e.g. SELECT field1, field2, field3, fieldN, count_rows() FROM table1 WHERE field99 LIKE 'G%' AND field66 = 7 OR field18 <= 5.7 LIMIT 341, 10 will return a maximum of 10 records but the count_rows() will return how many rows the query would return if the LIMIT was not in place? This would make paging of results very straight foreward and efficient. Anyone agree/disagree this would be useful? -- View this message in context: http://www.nabble.com/LIMIT+and+paging+records-t1698512.html#a4609360 Sent from the SQLite forum at Nabble.com.
