Paging in Advantage Database
i'm creating a web app that's running on an Advantage Database server, not my personal weapon of choice but that's what the company uses. I have a couple of big lists that the end-users need to be able to view however i can't seem to find a way to page through the results in SQL.
Is there something like LIMIT / OFFSET for Advantage Database? If no, any suggestions on approaching thi开发者_如何学编程s?
thank you in advance!
I understand that LIMIT and a ROWNUM will be new features in an upcoming version of Advantage. http://feedback.advantagedatabase.com/forums/2671-general/suggestions/30213-return-query-specific-row-number-?ref=title
However, until then, I have used this in the past to select row 50-60.
select top 10 * from mytable where rowid not in (select top 50 rowid from mytable)
@tommieb75, you indicated that the SQL dialect was not standard. I have found that it is based on the standards containing most of the SQL-92 standard and some of the SQL-2003 features.
Updating this for any stumbling here, but as Edgar mentioned in his answer, Advantage 10 SQL now supports a START AT
keyword.
SELECT TOP 10 START AT 11 * FROM emp
See: devzone.advantagedatabase.com/dz/webhelp/Advantage10.1/master_limiting_query_results.htm
According to this, the correct syntax for LIMIT
in Advantage is SELECT TOP 10 * FROM YOURTABLE
.
