Hi Experts,

To insert or update 2000 records in Ultralite Database through iOS application, it takes more than 2 minutes. How to reduce the time of insertion/updations?

I don't know Ultralite but, in general, the easiest way to speed up inserts with Sybase is to use insert ... select ... union pattern.

Basically, instead of doing:
insert into mytable (field1, field2) values (val1, val2)
insert into mytable (field1, field2) values (val3, val4)
...

Open in new window


do:
insert into mytable (field1, field2)
select val1, val2
union
select val3, val4
union
...

Open in new window

Hi ,

i tried the above option and if select statements are more than 34 , error : 685 from ultralite database. i think i need specific solution for ultralite.

Could be.  It appears that Ultralite has far smaller limits than other databases.  All databases will eventually give an error with this sort of construct but it is commonly in the thousands (or tens of thousands).
