hello

I'm trying to bcp in matrix of integers into SQL using SQL Server bcp.exe

<br />
1,2,3<br />
3,4,5<br />
6,7,8<br />

And bcp command as follows:

<br />
bcp.exe DEV.dbo.SomeIntData in C:\BcpTest\bcp\output\output_int_pc.txt -S SomeServerName -f int.fmt -T  <br />

In my formatting file:

<br />
9.0<br />
3<br />
1       SQLBIGINT    0       25       ","    1     Col1         ""<br><br />
2       SQLBIGINT    0       25       ","    2     Col2         ""<br><br />
3       SQLBIGINT    0       25       "\n"    3     Col3        ""<br><br />

My simple test table:

<br />
CREATE TABLE [SomeIntData](<br />
 [Col1] [int] NULL,<br />
 [Col2] [int] NULL,<br />
 [Col3] [int] NULL<br />
) <br />

Problem is, integer value of "1" when inserted (by bcp.exe) into database became "49" (ASCII value/code of "1") - Any suggestion?! Thanks!

Just an observation

We found that the BCP.exe in SQL 2008 was a lot more unstable than earlier versions. Apparently MS tightened up some of the formatting rules and it basically broke BCP. If you can make it behave then it is still the fastest load method.

We do not do any tansformation during the load, shove everything into varchar fields in a staging table. We then use stored procs to do the transforms. This gives us a number of advantages:

No errors in the load
Easier to manage the errors in the data when it is right there in front of you.
Dramatically faster - I mean hugely faster than either SSIS or Biztalk.

nooeee.... I have no time to play around or experiment - and how do you implement "Stored procs to do transforms"?

Thanks

You know what the data looks like and you know what/where it needs to be. So the staging tables have the original data, simply write an insert statement with the transformations and lookups (joins) to move it to your final format.

hey, I got it working - problem with bcp format file

if you follow MSDN advice and mark a field SQLINT (corresponds to database table col type), you'd end up having this int to ASCII conversion problem.

Just mark the damn field as SQLCHAR, and let db do conversion and all good.

Basically what I suggested in the first place, get the data in as char and deal with the crap after you have the data.

Is it possible to skip -f switch (i.e. not supply format file) and let bcp to do this job herself (i.e. infer field type auto like old days?) [modified]

13-Jul-10 0:29

Can we skip format file (-f switch) at all?

I got it working by indicating column tye SQLVAR instead of SQLINT and let SQL do conversion herself - however it's still ridiculous having (mandatory) to specify format file...?

Thanks

Hi All,

How to get sum of a column upto the current row for each row into a different column in SQL Server.

Hi,

There's multiple ways of calculating a running total. This article[^] shows three of those solutions.

Not sure how this differs from your earlier question http://www.codeproject.com/Messages/3527850/Complex-Query.aspx[^]

You're looking for running totals.

Not a full solution, but a step towards it:
Let us assume a table "Table1" with following columns and values:

ID val total
 1  12 <NULL>
 2  23 <NULL>
 3   2 <NULL>
 4  14 <NULL>

Now you can update the "total" column for each row with a query like the one below for ID=3:

UPDATE    table1
SET       total = tmp.result
FROM      (SELECT   MAX(ID) AS maxid, SUM(val) AS result
                    FROM          Table1
                    WHERE      (ID <= 3)) TMP
WHERE     table1.id = tmp.maxid

Next, replace "3" by a parameter and run the query for every ID value...

What with a cursor or a while loop, what happens if he has 100k IDs. This is a bad solution, using the running total tools will give a much better result.

TNS Ping (.NET Library)

I'm currently maintaining a Visual Basic project that makes use of tnsping. In order to do a tnsping, it uses a ProcessStartInfo instance to make the call as if it were using the command prompt(DOS). I was wondering if a library exists (Oracle.DataAccess maybe?) or if there's something built into the .NET libraries that will allow me to do the tnsping without the ProcessStartInfo. Could anyone point me in the right direction?

Thanks in advance for all of your answers.

to accept the null values of lastname and firstname...I used the 'isnull' which is not correct..Pls correct the procedure

Which database are we using here?

SQL Server does have an isnull function. For oracle checkout nvl. And for mysql I found this discussion of ifnull http://forums.mysql.com/read.php?98,198593

Try COALESCE instead of ISNULL

SELECT DISTINCT DECODE(DR_TimeIn, NULL,'NOT CHECKED',DR_TimeIn) as Date,
.............;

If you are using Oracle DECODE if the best.
OR for other Database Server:

SELECT  IIf(TimeIn is null,'NOT CHECKED',TimeIn) AS [Date],
........;

It looks like you just forgot to wrap EM_FirstName in an isnull. Otherwise I don't see why that wouldn't work with MSSQL.
