hi
how can i insert a record in a table if it doesnt exist already and update the record otherwise ie if record exists then it must be updated and if not exist then inserted.
is it possible through one query... For example :
TableOne
ColumnOne|Colum nTwo|....
jhon |123455|....
now a record jhon,10000 comes since jhon already exist so it must be updated
if steve,45 comes it must be inserted
Any suggestions.... . Thanks in advance...

You can use SQL Server 2008's new MERGE statement if using that version .That allows you to insert, update, or delete data based on certain join conditions in the same statement.
Thanks for ur reply DADA,
but i am using mysql 4.1 is it possible in that .. or i have to first run a query to check the existence of the record then update or insert.. that will be tooo time consuming but i dont have any choice .. can u suggest me a way...

Are you advertising for Microsoft software in the FREE MySQL forum? Shame on you.

Oh...
I am really sorry. I mistook that for SQL Server forum question.

You can do it in one query with REPLACE, BUT only and only when the old row in the table has the same value as a new row for a PRIMARY KEY or a UNIQUE index, . See the appropriate chapter in the MySQL documentation for your MySQL version HERE

No no no ........
Not at all . I actually mistook this as a SQL Server question in a hurry.
I am again sorry for that .

I want to be able to generate SQL statements that will go through a list of

Logically then, I would like to SELECT * FROM <TABLE>

INSERT INTO <TABLE> VALUES <Values...

been ruminating on the question (mostly in a 390/v7 context) of
whether, and if so when, a row update becomes an insert/delete.
i assume that there is a threshold on the number of columns of
the table, or perhaps bytes, being updated where the engine just
decides, screw it, i'll just make a new one.
surfed this group and google, but couldn't find anything.
the context: we have some java folk who like to parametize/

Hello,
I have created 3 functions to insert, update and delete an Access
database record. The Insert and the Delete code are working fine.
The update is not. I checked and my database has all the necessary
records in it when testing it. I get the error "No value given for one
or more required parameters." when I try to update the database.
Can you tell me what am I doing wrong?

So I have some data that I want to put into a table. If the
row already exists (as defined by the primary key), I would

I've been doing something like

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows.

For most users, this new feature is actually very convenient. If you want to control the update process,...
