problem with large number of inserts

We have an application that is connecting to our SQL 2k server remotely via
ODBC and sending a large number of individual insert statements. Apparently
this is causing problems with the transaction filling up on the sql database
the inserts are being sent to. To solve the problem, we set the transaction
log to be able to grow to 2GB. It quickly filled that space. Then we set it
to unlimited growth. Over time it grew to 12GB which began to cause other
problems. We backed up and ran DBCC Shrinkfile to bring it back under 1GB but
the remote app is not able to complete the inserts at that size. Truncate log
on checkpoint is selected in the database properties.
I found some KB articles which referred to problems doing large updates but
they had to do with using the 'where' statement and we are doing inserts with
no 'where' statement so it didn't seem to apply. Any ideas on how to solve
this problem?
Neither the Event Viewer nor the SQL Logs are offering much insight. No
errors are logged when the remote insert fails. However, the same database
appears to be failing to backup. During the weekly backup routine, we get
this in the Event Viewer:
"Could not clear 'DIFF' bitmap in database 'specialneeds' due to error 3617.
A subsequent backup operation may be slower/larger than normal."
We also get several variations of this message for both the Log and Database:
3041 :
BACKUP failed to complete the command BACKUP LOG [specialneeds] TO DISK =
N'E:\SQL Backup\specialneeds\specialneeds_db_200506190202.B AK', DISK =
N'E:\SQL Backup\specialneeds\specialneeds_Tlog.bak' WITH INIT , NOUNLOAD ,
NAME = N'specialneeds backup', NOSKIP , STATS = 10, NOFORMAT
We have 30 or so other databases, some larger some smaller, running on the
same SQL Server and none of them are having problems backing up. Thanks for
your help!
Hi
Run a DBCC CHECKDB on this database and see what it reports.

Problem with expression window in derived column

Hi,

i am facing problem to dervie one column value from another column using either if and case statements in expression window of dervived columns transformation.

let me give the exapmle. i get 1 column from source system name as "col a" and i want to insert 2 columns into my destination as col A and col B. based on the values of col A i want to derive the values of col B,like if col A value is 0 then col B value is Good else BAD.

Can any one asssit in this regard how to achive it? and is it possible to use IF and CASE statement in this dervived column tranformation?

Sreenivas

Select the Add New column option, call it ColB or whatever, then use an expression like this -

ColA == 0 ? "GOOD" : "BAD"

This uses the conditional operator, as documented in Books Online - http://msdn2.microsoft.com/en-us/library/d38e6890-7338-4ce0-a837-2dbb41823a37(SQL.90).aspx

Logicaly it reads like this -

If ColA Equals 0 Then

Return "GOOD"

Else

Return "BAD"

End If

Problem with dates

Hello,

I am trying to insert some date values into a table. I am using ODBC
prepared statements to (potentially) improve performance. The
statement syntax I am using is this:

INSERT INTO date_tests (date_col) VALUES ( CONVERT(DATETIME, ?, 121) )

The table is defined as "CREATE TABLE date_tests (date_col DATETIME)".
Then, I call this prepared statement in a loop to insert some date
values from an array. The values in the array look like this:
"1994-05-14 11:00:00:000" They are all valid dates and conform to the
ODBC date style supported by Sqlserver.

But I get the following error: [Microsoft][ODBC SQL Server
Driver]Optional feature not implemented.

I have tried different date formats and date values; but each time I
get the same error message. What is interesting is that if I use
straight "INSERT INTO " statements and not use a prepared statement,
there is no problem.

Will appreciate any suggestions and ideas to resolve this.Hi

Using the style parameter in the CONVERT function when converting to
datatime is not a documented option.

From BOL:
style

Is the style of date format used to convert datetime or smalldatetime data
to character data (nchar, nvarchar, char, varchar, nchar, or nvarchar data
types), or the string format when converting float, real, money, or
smallmoney data to character data (nchar, nvarchar, char, varchar, nchar, or
nvarchar data types).
