Is Ssis The Only Technology That Can Read/write Raw Data Type Files?
Sep 21, 2007
I'm contemplating a sql server archive strategy that rolls really old data off any sort of dbms and onto low cost media like dvds in a non relational archive format. I dont want to ever worry about these archives spanning different versions of sql when i go to retrieve a range of data that happens to span sql versions (eg one disc was sourced from 2005 another by 2008 but my report needs a union of both).
So I'm thinking about neutral/efficient formats for these archives and a live homegrown catalog that can determine exactly what disc(s) need to be mounted based on passed from and to date parameters...all so that the data that might span discs (and versions and maybe even schemas) can be merged and loaded into my sql version d'jour's "throw away" archive database for a one time report or other unplanned activity.
I remember raw data types being very convenient as an ETL format for our customers who have ssis, but wouldn't want our sqlexpress customers to be left without the archiving capability. Do the "things" that read and write raw data files really originate in some special T-SQL command that all sql editions can use, or is it strictly an ssis thing?

I have two database files, one .mdf and one .ndf. The creator of these files has marked them readonly. I want to "attach" these files to a new database, but cannot do so because they are read-only. I get this message:
Server: Msg 3415, Level 16, State 2, Line 1
Database 'TestSprintLD2' is read-only or has read-only files and must be made writable before it can be upgraded.
What command(s) are needed to make these files read_write?
thanks

I'm trying to import data from a Sybase ASE 12.0 database called "OurTestDatabase" into MS SQL Server 2005. I started SSIS Wizard and indicated "Sybase ASE OLEDB Provider" as a source and SQL Native Client as the target. I'm gettign the following error message:
-----------------------------------------------------------------------------------------------------------------
Cannot get supported data types from the database connection
"Provider=Sybase.ASEOLDEDBProvider;Password=;Persist Security Info=True;User ID=sa;Data Source=sybase;Initial Catalog=OurTestDatabase"
Additional information
|_ Attempted to read or write protected memory. This is often an indication that other memory is corrupt. (System.Data)
-----------------------------------------------------------------------------------------------------------------
The same data source worked with DTS when we thought we'd convert to MS SQL Server 2000. Is this a bug in SSIS? What can be done? Using ".Net Framework Provider for ODBC" is not a good option because this doesn't allow me to choose any tables from the Sybase source.
Any help is greatly appreciated.

Hi,
I am trying to develop a SSIS package which will read the records from the flat file and insert them into a destination table. I have some validations written in script component. I have declared two Read Write variables with package level scope. when i try to assign a value to the variable in the script component and run the package, the package throws me an error "The collection of variables locked for read and write access is not available outside of PostExecute".
What should be done to over come the problem please help me on this regard

I was wondering if it is possible to read image data from a database in .net compact framework. Since cf does not have image.fromstream(memstream) to work with, I don't know how else to read the image from the database and then place it into a picturebox.
Here is the code I have been trying out:
Dim Img As Image
'
Dim conn As New SqlCeConnection("Data Source = My Documents est2.sdf")
conn.Open()
Dim sql As String = "SELECT * FROM Dater"
Dim cmd As New SqlCeCommand(sql, conn)
Dim reader As SqlCeDataReader = _
cmd.ExecuteReader(System.Data.CommandBehavior.CloseConnection)
While reader.Read()
TextBox1.Text = reader.Item("name")
Dim b(reader.GetBytes(1, 0, Nothing, 0, Integer.MaxValue) - 1) As Byte
reader.GetBytes(1, 0, b, 0, b.Length)
Dim ms As New System.IO.MemoryStream(b)
Dim bmp As New Bitmap(ms) <-Error: Value does not fall within expected range
Img = bmp
End While
PictureBox2.Image = Img
I get an error ,Value does not fall within expected range.
Does this mean the image was not save correctly in the database?
Thanks for any help

Hi,I have a web app, that runs fine, except for one particular section that uses a class called by an event in the code behind. The class resides as a dll in the bin folder. We had no problems during testing, when only one user was running this dll. Problems soon occurred when multiple users tried running it. Here's the error & stack: 06/02/2007 09:25:26 ==> cburns ==> There is already an open DataReader associated with this Command which must be closed first. at System.Data.SqlClient.SqlInternalConnectionTds.ValidateConnectionForExecute(SqlCommand command) at System.Data.SqlClient.SqlConnection.ValidateConnectionForExecute(String method, SqlCommand command) at System.Data.SqlClient.SqlCommand.ValidateCommand(String method, Boolean async) at System.Data.SqlClient.SqlCommand.RunExecuteReader(CommandBehavior cmdBehavior, RunBehavior runBehavior, Boolean returnStream, String method, DbAsyncResult result) at System.Data.SqlClient.SqlCommand.RunExecuteReader(CommandBehavior cmdBehavior, RunBehavior runBehavior, Boolean returnStream, String method) at System.Data.SqlClient.SqlCommand.ExecuteReader(CommandBehavior behavior, String method) at System.Data.SqlClient.SqlCommand.ExecuteReader() at ESP.Validator.Data.DatabaseEvents.DatabaseEventManager.Read(IEventable eventObject, Int16 eventType, DateTime earliestDate, DateTime latestDate) in C:My PathValidatorValidator.NETDataDatabaseEventsDatabaseEventManager.cs:line 92 at ESP.Validator.Data.Translink.CATCard.GetDespatchDate() in C:My PathProjectsValidatorValidator.NETDataTranslinkCATCard.cs:line 94 at ESP.Validator.Data.Translink.ExistingSchemeEntitlement.ReadCards() in C:My PathProjectsValidatorValidator.NETDataTranslinkExistingSchemeEntitlement.cs:line 215 at ESP.Validator.Data.Translink.ExistingSchemeEntitlement.Read() in C:My PathProjectsValidatorValidator.NETDataTranslinkExistingSchemeEntitlement.cs:line 147 at ESP.Validator.Data.Translink.TranslinkApplicant.ReadEntitlements() in C:My PathProjectsValidatorValidator.NETDataTranslinkTranslinkApplicant.cs:line 369 at ESP.Validator.Data.Translink.TranslinkApplicant.Read() in C:My PathProjectsValidatorValidator.NETDataTranslinkTranslinkApplicant.cs:line 353 at ESP.Validator.Data.Translink.PrePrintedLetter.Read() in C:My PathProjectsValidatorValidator.NETDataTranslinkPrePrintedLetter.cs:line 282 at ESP.Validator.ValidationProcessor.Read(ValidationSubject subject) in C:My PathProjectsValidatorValidator.NETValidationProcessor.cs:line 82 at clear_applications_scan_applications.ProcessValidation() It seems the data reader is getting reused. We have ensured after each read the reader is closed. Though all users are using the same connection string. Could it be a connection pool problem, with the connection being overwritten during execution? Should i edit it according to the users logon?I am really at a loss for ideas, and I don't mind admitting I am a bit out of my depth with this one!! Any ideas/suggestions would be greatly appreciated. Thanks

Hi,
I want to do the following with a ssis package:
INPUT:
A table contains 2 columns with data i need. column A=Filename and column B=FileContent
PROCESS:
I need to loop through ea record in the table and retrieve columns A and B. Then for ea column i need to write the Content hold in column B into File hold in column A.
I so far found out, that i need a Execute SQL Task in Control Flow querying the table and get columns A and B into 2 variables, plus a 3rd var holding the object. Then the output goes into a Foreach Loop Container. From this point i don't know how to continue. I tried to put a Data Flow Task inside the Foreach Loop, but couldn't find out how i now get the 2 variables to the Data Flow Task and use them to for the file to be written and the content to be placed in the file.
Is there any example similiar to that so i could learn how to start on that?
Thanks
Danny

Hi all,
I have a column in SQL server which is of type ntext. Selecting the specific column to view it in report builder, an error message appears with the following description:
- Cannot run this report. The grouping expression 'nameofcolumn' returns the datatype binary. The Grouping Expression cannot return binary data.
Report Builder recognises this as if it was an image...
Thanks in advance!

We have some columns in a table where the date is stored as 19980101 (YYYYMMDD). The data type for this column is NUMBER(8) in Oracle.
I need to copy rows from Oracle to SQL Server using SSIS. I used the Data Conversion transformation editor to change it to DT_DATE, but the rows are not being inserted to the destination.
On Error, If I fail the component, then the error is :
There was an error with input column "ORDER_DATE_CONV" (1191) on input "OLE DB Destination Input" (29). The column status returned was: "Conversion failed because the data value overflowed the specified type.".

We are in the process of upgrading to a new SQL 2012 server but we have many packages that load data from dbf files created with FoxPro into one of our databases. We have not converted the packages and run them with DTS but we get the following error:
Error: 2013-08-26 11:05:27.36
Code: 0xC0209303

I searched for OLEDB and ODBC drivers for SQL 2012 64 bit but cannot find any that is newer than the 2005 that we have. What can I do short of changing the source files to overcome this issue?

Hello,
I have 2 tables EmployeeA(Eng) and EmployeeB(Spanish) kept in seperate mdb's. I want to add the records into Sql Server 2005 table called StateEmployee.
Procedure:
1. Loop through 2 folders..one containing table EmployeeA in mdb and other containing tbl EmployeeB in diff mdb's.
2. Pick a file from EmployeeA and EmployeeB, both at the same time.
3. Count the total no of rows in both files. If equal proceed.
4. Compare the 'employeeid' of one row of employeeA to the employeeid of EmployeeB.
5. If employee id matches, load both the rows in Sql server else file it to the error table.
6. Loop through all rows simultaneously till end of row.
7. Go to next mdb.
How do i go about this step by step. I am fairly new to SSIS.

I have a SSIS package which reads an excel file and loads data into a table using script component(C#) as a source. The package runs without any errors when I manually run it on my machine and on the server. But the package fails when run as a SQL Server Agent job.
I tried all the possible fixes I found on the web but still can't get it to work.

I have a requirement to
a. Read data from Different CSV files.
b. insert and update data to Data base in multiple table using joins.
This execution runs for 1-2 hours.I can use C# with Ado.net, but only concern I see is if in between execution fails due to some connection or other error. All insert data has to be cleaned up again.I feel writing and Store procedure inside transaction, which will take path's for CSV file as input and insert data in database. using transaction we will have flexibility rollback to original state.

I am currently investigating aa high avg write time ms issue (145ms) which seems to be only occuring on the tempdb data files.I have followed the recommended setup of TEMPDB in that
1. Data files = number of physical cores
2. Data files and logfiles are on separate partitions away from the other databases.
3. Tempdb is presized and no incremental file increases look like they are happening with frequency.
We have sharepoint 2012 setup on other sql servers and with TEMPDB setup following the same guidelines, with far more Sharepoint activity on a similary specified hardware which is why its confusing.FileIO auditing on the partitions themselves shows that the FileIO is very fast on the partitions that the tempdb data file which leads me to beleive that Sharepoint may be the culprit perhaps due to excess use of tempdb with operations taking a long time to resolve.

Hello,
We currently run sql 2005 server and also sql express in our dev environments. We use sql express as an offline store (smart client). We have a similar/exact schema on the sql 2005 server and also the express.
We use the auto attach feature to connect to the express version of the database. Both the developer machines and the one that is running the sql 2005 server have exactly the same hardware configuration. The only difference may be that the server box is not running the VS.Net environment. The disk space etc is pretty much the same. Actually we run another database server(DB2) on the 2005 server machine.
We have observed that sql express is much slower and queries execute much slower aswell. For example, this may not be a totally scientific way of checking but a long running query on the server took only 2 minutes while on express it took longer than 9 minutes. The schema and data etc are the same.
Is there something we need to look into as far as read write speed/performance goes ?
TIA,
Avinash

Okay, maybe I'm getting ahead of myself.
Using SQL Server Express, VWD and .net 2.0 I've figured out how to drop a Table Column Constraint or Default Value/Binding and then Create it again using a stored procedure. What I can't figure out is how to retrieve that column's constraint value and write it to, say a label, in an aspx page, simply for reference. Is it possible? In this case the Data Type of the column is money.
I'm using it to perform a calculation to a column with a value that the user inserts into another column. (Column1(user input) minus Column2(with Default Value) = Column3(Difference). I just want to read Column2's Default Value for reference so I know whether to change it or not.

Hi,
I was reading that many of these high traffic websites actually have 2 databases, 1 database is used ONLY for reads, while the other is for writes.
How does one go about creating such a setup? How does the database where writes are allowed replicated the data to the read only database server?
