DataSet rows being deleted, but after the update , the sql database is not updated. The delete rows still in the database.
Stepping thru the code with the debugger shows the dataset rows being deleted.
After executing the code, and getting to the page presentation. Then I stop the debug and start the
page creation process again ( Page_Load ). The database still has the original deleted dataset rows.
Adding rows works, then updating works fine, but deleting rows, does not seem to work.
The dataset is configured to send the DataSet updates to the database. Use the standard wizard to create the dataSet.

I used sqlanywhere 188.8.131.52 database to store some pictures in a long
binary field , the
database file became very big soon , when I want to shrink the size of
the database file ,
I deleted all rows , however the database file became bigger (In this
database I didn't
use a log file),who can tell me why ? Thanks!
Deleted rows are not removed until you rebuild the database. I don't know
why the database got bigger, but I'm sure that if you rebuild the database,
it will physically remove the deleted rows.

I have 2 gridviews on a form, the first displays some template rows from a database table.
The second displays some user specific rows (with additional data added to the template info) from the same table.
They both work fine for displaying the info.
Now what I want to do, is allow users to 'select' a template row on the first gridview, and have that action automatically:
create a new user-specific row, with added fields from profile data etc.
insert it into the table
then refresh the second gridview in order to show the new added row.

I have a SQL remote replication setup with a central consolidated database
and many remote databases.
For simplicity sake I have a table called period_sale (sale_code,

I used a CurrencyManager in a windows form to traverse row-by-row on the records in a database. Can anyone help me out in using a similar feature in asp.net to traverse through the records row by row. Is there any in-built feature? I tried using a dataset to traverse through but I think it might be better to use an in-built feature as te code used in it might be optimised.

I think this question is bugging not only me, but I have not found anything related to it so..listen.
The "DELETE" function doenst actually deletes the records, it only puts the property "deleted" on the record, so.....my database file is about 15MB, eventhough I dont have any records on it.....
Does anybody know how can I delete those deleted records.
I know in FoxPro there is a "PACK" function that cleans the db.
Thank you for your help.
You need to do a "Compact and Repair". Others have posted code for this.
Howeve...Database SPACE after Delete Rows
After deletion of many rows in 2 tables, the size of my database
(SqlAnyWhere Studio 6.0) is the same.
How can i schrink the database ?
The free space will be re-used for new data so it is not wasted. If
you really want to shrink the size of the file you must dbunload,
delete and recreate the database with dbinit, and then run reload.sql
