Hi,
I'm a newbie and I'm attempting to learn howto create a select statement.
When I use
>>> string1='18 Tadlock Place'
>>> cursor.execute("SELECT * FROM mytest where address = %s",string1)
All works as expected. But
>>> numb=10
>>> cursor.execute("SELECT * FROM mytest where clientID = %d",numb)
Traceback (innermost last):
File "<stdin>", line 1, in ?

I am going to drop a primary key from one column and create a new
column to be used as primary key in an existing database.
The old column was a date column which someone earlier though was a
good candidate for a primary key which we all know it's not.
Now I want to add a new field, i.e. called ID, with a normal number
sequence as primary key.
I have dropped the primary key, created the new column, created the
new sequence and created...

I am trying to copy data from one table to another, and in the process
add a sequence number to copied rows. I have looked at the IDENTITY
function when creating tables, and essentially this is the behavior I
am trying to duplicate.
However, my question is if I can do this with the SELECT INTO
statement as well. I have tried a few variations and it does not seem
to work:
SELECT seq_number = identity(10),

I apologize if this is redundant.
How would one fill an empty column with a sequence of numbers? The
column exists in a table with aproximately 1000000 rows of data. I
believe in oracle the following would work:
update foo set bar = rownum;
....but 'rownum' does not seem to exist in mssql. The numbers do not need
to be in order, but I would like to keep them somewhat small.

I have the following query that has been working so far. I modified
it slightly to work from another source table (new_products). Now,
SQL Server complains that the identity is inherited already:
"Cannot add identity column, using the SELECT INTO statement, to table
'dbo.my_products', which already has column 'id' that inherits the
identity property."
Any suggestions for a work aorund?

I'm sure this is an obvious question but much of SQL is new to me.
I have a stored procedure and I want to use the results of a select
statement elsewhere in the stored prcedure. The select statement will
return at most one record and only one column, here's an example :
select top 1 Sequence from MyTable
where ParentId=4 and Sequence > 200 order by sequence

I need to maintain a manually counter for an id-field, but I can do this
two ways. Either make a counter table (which means one select and one
update) or just selecting the largest id from existing table and
increment by one (just one select + one table lock). Which one is
fastest?

I just ran into a dump/restore problem with a bigserial column
on a renamed table.
BIGSERIAL columns when created will automagically create
the sequence also. The sequence name is derived from
the table name and column name.
I had a table named 'audio_usage' and defined a column like this:
ausage_id BIGSERIAL

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
