Yes, but embedded in something Pascal-like? I haven't done PRO*C for more than ten years.

Well, that's PL/SQL, it's meant to look like ADA or Pascal.
PL/SQL != Pro*C

It looks like you're missing the keyword loop after for i in c1 and after for j in c2
Try this:
DECLARE
cursor c1 is select * from dept;
cursor c2 is select * from emp;
s emp.sal % type;
BEGIN
for i in c1
loop
s:=0;
dbms_output.put_line(‘
dbms_output.put_line(‘Department is:’║ i.deptno║’Department name is:’║i.dname);
dbms_output.put_line(‘
for j in c2
loop
if(i.deptno=j.deptno)then
s:=s+j.sal;
dbms_output.put_line(j.empno║ ‘ ‘║j.ename ║’ ‘║j.sal);
end if;
end loop;
dbms_output.put_line(‘
dbms_output.put_line (‘Total salary is:’║s);
dbms_output.put_line(‘
end loop;
END;

I have got a problem with modifing the tables of MDF because the LDF file cannot make a corresponding changes.
I used SQL2000 manager to ouput a table of mydata(game database) to a xls file. Then I used Excel to make changes to it, since Excel is easy to manage a great number of entries. After having finished that, I converted xls file back to the table in mydata. Something went wrong, cuz I hadn't update the corresponding LDF file.
Could someone give a solution? many thanks.

NEVER trust Excel to handle data output.
Reports are okay, but Microsoft knows all and since you really do not want that 16 digit account number to be text, they make it scientific notation dropping the last few digits in the process. That leading zero is defanintly not needed. 1.1 well that should really be 1.10000000102.
These are NOT a rant they are fact (except the value shown for the decimal).
Get a good text editor. I believe NotePad++ will do it and there are several pay to use packages that say they handle large files (I use VEDIT).

Just wondering how you converted an xls file "back to the table in mydata"?

I have two tables like this
Sales table Purchases table
--------------------- ------------------------------
SaleDateTime | Cost PurchaseDateTime | Cost
--------------------- ------------------------------
02-09-11 | 35 02-09-11 | 48
03-09-11 | 35 02-09-11 | 48
06-09-11 | 35 04-09-11 | 48
07-09-11 | 35 05-09-11 | 48
08-09-11 | 35 08-09-11 | 48
I want to produce result like this
Date | Sale_total | purchase_total
--------------------------------------------
02-09-11 | 35 | 96
03-09-11 | 35 | 0
04-09-11 | 0 | 48
05-09-11 | 0 | 48
06-09-11 | 35 | 0
07-09-11 | 35 | 0
08-09-11 | 35 | 48
how can I do this ?
Additional info:-
I am using MS Access.

You can divide this task into three parts. The first part uses inner join to find the records from both tables with common date/time. The second part deals with the case that date/time only appears in the first table. The third part deals with the case that date/time only appears in the second table. The result is a union of the above three queries.
To show you what I mean in a cleaner example, let's suppose the first table is called "Table1" with the following two fields: a1 and a2 (corresponding to your "Sales" table's SaleDateTime and Cost columns), and the second table is called "Table2" with the following two fields: a1 and a2 (corresponding to your "Purchase" table's PurchaseDateTime and Cost columns). The following query should give you what you wanted.
SELECT a.a1, sum(a.aa2), sum(b.aa2)
FROM (SELECT a1, sum(a2) as aa2 FROM Table1 GROUP BY a1) as a,
(SELECT a1, sum(a2) as aa2 FROM Table2 GROUP BY a1) as b
WHERE (a.a1=b.a1)
GROUP BY a.a1;
UNION
SELECT a1, sum(a2), 0
FROM Table1
WHERE a1 not in (SELECT a1 FROM Table2)
GROUP BY a1
UNION
SELECT a1, 0, sum(a2)
FROM Table2
WHERE a1 not in (SELECT a1 FROM Table1)
GROUP BY a1

It is difficult to join datetime fields because of the time portion.
What appears as 09-10-11 may actually be stored as 09-10-11:09:30.00.00 in one field and 09-10-11:12:49.46.50 in another. So when you look at the date portion you would think they're the same value but they're not because of the time portion.
|
|
|
|

Actually I modified the fields
SaleDateTime and PurchaseDateTime. These fields contain only date values like 09-11-2011.

You may have changed the display, that doesn't change the actual date value which still includes the time portion. So the date may display as 09-11-2011 but the real value may be 09/11/2011 08:30:20:15.
Anyway, try joining using those fields and see what you get.

|
|
|

yes you were right.
I had to change actual data of those fields.
thanks

What do you mean by "publish"?
The data from a SQL Server database can be replicated many ways (backup/restore, detach/attach, ...). You need to have a SQL Server accessible by the client.
If you mean publish as with a .NET program that is a different problem.

Development phase.
1. Create one or more scripts that create the database
2. Create one or more scripts that populate the database.
3. CHECK them into source control.
4. Label them
5. Extract USING the label and store as a 'delivery' in the file system some where. Call this location X (it will be related to a delivery version number.)
Install phase
1. Notify the production personal what X is (related to the verifie version.)
2. Production personal use a dabase id SPECIFICALLY for installs, and nothing else, to run the scripts appropriately.
3. Verify that the database is 'working' using something methodology probably involving other applications.
There are all sorts of variations on the above.

Hi,
I have a stored proc, which converts a pdf to tiff files.
Now, I need to rename these tiff files. The main file name is maintained but the last part of the file name changes to xxx00001.tif - xxx is my file name.
How can I check if the main part of the file exists, just xxx part so I can rename it? When I use the fileexist, it looks for the entire filename and hence not finding the file.
any help is appreciated.

Hello folks
say for example you have a company with various branches; each branch implements its own database (each DB has its own structure and data); one wants to make use of all the databases in the branches and their data;
how would you go about it then?
Some might go for heterogeneous databases tools; some others might suggest using SQLserver or any other DBMS for all DBs(will it handle that large data? isn't it very costly?); someone else might suggest going for a data warehouse?
How would you go on about it?

Sql Express, one per branch, until they outgrow it. The "one" you're referring to could access the data it requires over some webservices from those database. Unless it's for reporting, then I'd simply go for a script that backups each database locally and then send that off once a day.

Convince management to grow a set of balls and force through a decision on the data structure. The Branches do the same thing so make them do it the right way. Supporting this sort of wimpy management process is a complete disaster, you are either 1 organisation or you are not.
There is however a strategy I have used when management cop out completely (also used when merging disparate systems). That is to define a reporting structure, this structure is set by management and the branches decide what they want to put in the report elements. It is complex, difficult and hugely expensive in both time and development cost and is difficult to support but hey if they can't make a decision then they have to pay for it.
Sorry for the rant but I live with this every day, and yes I have called management on it!

String or binary data would be truncated is the nice SqlException one gets from SQL Server when attempting to insert/update a record with a string value that is longer than the field is wide.
That raises 3 questions:
1.
what would be the recommended approach in general?
2.
what would be the recommended approach in a medium-size application (lots of insert/update statements, no SP), when the user doesn't care much and would be happy when the strings where truncated without notification?
3.
is there a simple way to identify which field is overflowing?
TIA

Validate your data before you attempt to insert it.

I doubt that is a valid use case.
For example it would certainly never be valid to truncate the delivery address on an order.
So at most you might have one column where it might be acceptable to delete something. Say it is a 'comment' field but it that case your user experience is going to be that they typed a lot of stuff in and it just disappeared.
Again a much better idea is to validate the data first.

In theory sure. However it seems to imply the GUI knows all the database field widths, or alternatively the DB knows how to identify the failing field and pass that on to the GUI. Hence my third question.
