Error: Cannot open database requested in login projectAllocations. Login fails. Login fail

Hi,
Im getting this error when attempting to retrieve data from an sql database.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.Data.SqlClient.SqlException: Cannot open database requested in login 'projectAllocations'. Login fails. Login failed for user 'sa'.

Source Error:

Line 13: objConn = New SqlConnection( "Server=LAB303-066\NETSDK; Database=projectAllocations; User ID=sa;Password=mypassword")
Line 14: objCmd = New SqlCommand("SELECT * FROM project_descriptions", objConn)
Line 15: objConn.Open()
Line 16: objRdr = objCmd.ExecuteReader()
Line 17: While objRdr.Read()

Source File: C:\finalyearproject2\sample.aspx Line: 15

Please Help!! Im a beginner to this, so if anyone knows the answer, take baby steps when explaining. Thanksas the message says you prbly need to give permissions to the user to access the database. in your enterprise manager, if you xpand the databases tab and then the db you are working on, there's a Users tab. click on it and in the panel to your right you would see a list of users. You might need to add the user "projectAllocations" to the list here and give permissions to the user to access the tables/stored procs and other objects..

hth|||Hi,
Thanks for the response. When I login to the web data administrator and expad the database im workin on, there is no users tab. Does the database have to be empty to do this?|||>>in your enterprise manager, if you xpand the databases tab

Error while converting Oracle Timestamp to Sql Server Timestamp (datetime) - "Invalid date

I am populating oracle source in Sql Server Destination. after few rows it fails it displays this error:

[OLE DB Destination [16]] Error: SSIS Error Code DTS_E_OLEDBERROR. An OLE DB error has occurred. Error code: 0x80004005. An OLE DB record is available. Source: "Microsoft OLE DB Provider for SQL Server" Hresult: 0x80004005 Description:
"Invalid date format".

I used this script component using the following code in between the adapters, However after 9,500 rows it failed again giving the same above error:

To convert Oracle timestamp to Sql Server timestamp

If Row.CALCULATEDETADATECUST_IsNull = FalseThen

If IsDate(DateSerial(Row.CALCULATEDETADATECUST.Year, Row.CALCULATEDETADATECUST.Month, Row.CALCULATEDETADATECUST.Day)) Then

dt = Row.CALCULATEDETADATECUST

Row.CALCULATEDETADATECUSTD = dt

EndIf

EndIf

I don't know if my code is right . Please inform, how i can achieve this.

What is the value of the offending row? Redirect the error rows from the SQL dest and see what the offending value is.

The fact that it gets through 9500 rows and then dies means your logic is right but there is a dodgy row.|||

Thanks for your support, Crispin,

I redirected the output at destination (Fail Point) as you said and can see that some columns are displaying the Errors instead of the actual data that gives the clue about which is invalid)

Column 5

Error: Year, Month and day parameters describe an unrepresnatable date and time...

I doubt that the DateSerial function in the script component is unable to extract some formats..

So,

1) Does anybody know which representations and range of Oracle (timestamp) is not allowed in Sql Server (Datetime)
2) Do we have a stable code that can perform Oracle timestamp to Sql Server conversion here

Thanks

Hi Experts in SSIS forum,

Thanks to LoRez who has raised this question this month again.. I am still having the same problem in SSIS. I have an Oracle timestamp Source Columns that should be populated into Sql Server Datetime columns. Though I am aware of the ranges valid for both the cases, I was unable to frame it properly. . The expression (This only checks the Date Part , I wanted code that converts the time part of the Oracle timestamp into Sql Server Datetime) I have used to convert this is:

(!ISNULL(REQUESTED_ETA_DATE_CUST) && DATEPART("yyyy",REQUESTED_ETA_DATE_CUST) > 1752 && DATEPART("yyyy",REQUESTED_ETA_DATE_CUST) < 9999) ? REQUESTED_ETA_DATE_CUST : NULL(DT_DBTIMESTAMP)

Though the expression syntax is valid, it still gives error when I run the dataflow. The error is:

[Derived Column [136]] Error: SSIS Error Code DTS_E_INDUCEDTRANSFORMFAILUREONERROR. The "component "Derived Column" (136)" failed because error code 0xC0049067 occurred, and the error row disposition on "input column "REQUESTED_ETA_DATE_CUST" (372)" specifies failure on error. An error occurred on the specified object of the specified component. There may be error messages posted before this with more information about the failure.

Though http://forums.informationbuilders.com/eve/forums/a/tpc/f/1381057331/m/7121008802 helps to create a trigger, but not the way we can achieve using SSIS.

Greatly Appreciate if anybody can pointer or paste the Expression or .NET code that can convert Oracle timestamp into Sql Server Datetime without issues

Thanks

Dear Umachandar, Thanks for briefing up the approach.

I'd appreciate if you go one step ahead to help my case work.Oracle Timestamp in my case is of the format 'MM/DD/YYYY hh:mm:ss.nnn' and I do not have any control over oracle source. Somehow I must be able to use this to populate the Sql Server datetime. We know that the year should be grater that 1752 which we can validate using above expression. But Validating TimePart seems to be difficult. I tried casting to string, but due to omission of leading zeros makes it difficult to substring that. So do you have a solution for this?

Umachandar's Reply

Oracle timestamp range subsumes that of SQL Server's datetime range. So you will not have any issues as long as you use the ISO 8601 format to specify the values (YYYY-MM-DDT hh:mm:ss.nnn). This will ensure that the value will be stored correctly irrespective of collation settings on either servers or Oracle session setttings. You can use timestamp with appropriate precision on Oracle side (timestamp(3) is closest) to match SQL Server datetime.

Migrating values from Oracle to SQL Server is a different ballgame. You will lose precision, values etc. Oracle has more richer support and wider ranges & ANSI SQL implementation.

I've put up an article for this on my blog.

Cast this Oracle timestamp Column REQUESTED_ETA_DATE_CUST as below:

Decode(trunc((Extract(YEAR from REQUESTED_ETA_DATE_CUST))/1753), 0,'01/01/1753 12:00:00 AM', TO_CHAR(REQUESTED_ETA_DATE_CUST, 'MM/DD/YYYY hh:mms AM')) as REQUESTED_ETA_DATE_CUST

Or

Go for filtering valid ranges using SSIS transform after casting into a accepted datetime format.
