SQL Server 2014 :: Encryption And Data Length Limitations?

Feb 2, 2015

I'm having an issue in encrypting large documents. I know that previous editions ENCRYPTBYKEY had a maximum size of 8,000 byte limitation. Does SQL Server 2014 have any new features that overcomes this limitation?

DTS Fixed Field Length File Limitations

Jul 20, 2004

I am trying to upload a fixed field text file to a sqlserver table using the DTS wizard. The txt file has 111 columns and the total length of a single row is 5897. The problem is when I use the wizard to specify the starting and ending of each column, its not allowing me to specify the columns beyond the position 4095.
Is there a limitation on this? if so is there a work around ? to solve this.
Any help on this is truly appreciated.

Thanks much. :)

SQL Server Admin 2014 :: Using Column Encryption With Symmetric Keys

Jun 25, 2015

I am trying to implement the column encryption on one of the tables, have used the below link as the reference and got stuck at the last step.

[URL] ....

I have completed the following steps so far.


WITH SUBJECT = 'A label for this certificate'

IDENTITY_VALUE = 'a fairly secure name',

[Code] .....

Example by using the function

EXEC OpenKeys

-- Encrypting
SELECT Encrypt(myColumn) FROM myTable

-- Decrypting
SELECT Decrypt(myColumn) FROM myTable

When I ran the last command :

-- Decrypting
SELECT Decrypt(myColumn) FROM myTable

I get the following error :

Msg 257, Level 16, State 3, Line 2
Implicit conversion from data type nvarchar to varbinary is not allowed. Use the CONVERT function to run this query.

Where will I use the convert function, in decrypt function or in select statement?

Encryption Varbinary Length

Nov 9, 2006

Using the new encryption included in SQL Server 2005, what is a good way to determine what length I should use for the column? 

For example, I am encrypting a column, its maxlength is about 30 characters, but when encrypted, the encrypted value extends from between 50 and no more than 68 characters-

So if I had a column with a max of 500 or so characters, how could I know what varbinary length I should set it to if I were to encrypt it, without actually finding the highest value I could possibly fit into the field?

Is it good practice to just make it a varbinary(max) field?

Is There Limitations To Importing Data To SQL Server Express

Apr 7, 2007

I have software that uses SQL Server Express as it's database. I am only able to import so many records until it stops and fails to allow me to import anymore.

I'm very new at this but, is there some type of limitation on Table size that's preventing me from importing anymore data?

I'd really appreciate it if someone could help me,

Thanks... Bill

BlobColumn.GetBlobData() With Data Length &&> Integer Length (32767)

Mar 27, 2008

For those of you who would like to reference my exact issue, I'm dealing with the RSExecution SSIS package at the "Update Parameters" data flow task, at the Script Component.

The script tries to split parameter data into name and value. Unfortunately, I have several reports that are passing parameters that are very large. One example has over 65,000 characters all in the normal "&paramname=value&parm2=value..." format.

The code in the script works fine until it gets to one of these very large parameter sets. I have figured out what is causing the issue. Here's some code:

Dim paramBlob as Byte()
paramBlob = Row.BlobColumn.GetBlobData(0, Row.BlobColumn.Length)

The second parameter of the .GetBlobData function takes an INTEGER as its count! Therefore, no matter what kind of datatype I pass to the string that the script will later split, it will be limited to 32767 characters.


Does anyone know a workaround for this issue? I need all of the parameter data to be reported, and I would hate to have to skip over rows like this. Also, if I'm missing something, please fill me in!

Thanks for your help in advance,

SQL Server Admin 2014 :: Restoring A Database Even If No Database Or Backup Encryption

Sep 3, 2014

I did tried the encryption on server "A" for database "AdventureWorks2012". Then I tried to restore to server "B". There was the certificate issue, and I thought "of course : it's encrypted ! Let's deactivate it". So here I go "ALTER DATABASE AdventureWorks2012 SET ENCYRPTION OFF".I look at sys.databases : not encrypted.I backup using no encryption, I verify using msdb.dbo.backupset : not encrypted.

I move my backup to my other server where encryption was never configured (so no certificate, nothing...), and I have the error :
Msg 33111, Level 16, State 3, Line 1

Cannot find server certificate with thumbprint '0xFA130E58C999C4919B8975999C83A75A403B11D8'.

SQL Server Data Length Problem

Jun 9, 2006

Hi all,

I want to enter the below data into a database...

PHP Code:

 insert into price_list(price_list, price_list_note) values('MDC2 Close','This price list represents all close prices sent electronically by the vendor (FT InteractiveData ("IC")) for all US Debt securities. IDC data can be looked up through the website or through a Geneva price query'); 

However the price_list_note data gets truncated. Only first half gets inserted into the database.

Why is this?

I'm using Data Type Varchar with Length=8000
Also tried text(16)

Any ideas?? Thanks.

Data Type And Length In SQL Server

Nov 4, 2005

Hello folks!

I have written a stored proc that selects data from this table:

and puts it another table in this manner:

In short, I wanted to concatenate data in the second column.

My question is for some reason, SQL Server is limiting the length of the string to only 256 characters, even though I have defined the local variables in the storeds proc as varchar(1000) and the table has that field defined as text.

Any ideas how I can get around this problem?

Data Encryption (SQL Server 2005)

Jan 25, 2008


I store data in an .mdf file (I use SQL server 2005), because this way it's easier to move the application from one machine to another.

I've faced a problem with the encryption of the database.

Is there a possibility/way to encrypt a database file so that, if someone else finds/copies the mdf, he/she won't be able to read it.

I thought about encrypting the string values of the tables itself and decode them inside the application and encide when Inserting, but why inventing somehing that might already exist.

Thank you.

String Data, Length Mismatch When Using Linked Server

Oct 16, 2007

I have a sp which works fine from my local database.
I move the procedure to a different database and modify it to access my data via linked server and I get the following:

provider "SQLNCLI" for linked server "Production" returned message "String data, length mismatch".
Msg 7421, Level 16, State 2, Line 27
Cannot fetch the rowset from OLE DB provider "SQLNCLI" for linked server "Production". .

Now I've seen references to this error message for ODBC, but as I said above, the same SP works fine if it goes against local data views. I am working with rather long concatenated strings using nvarchar(max) as the data type.

I've tried cast() on just about everything to no avail.

Anyone have any other ideas?

SQL Server 2005 Data Encryption Issues

Oct 27, 2006

I read a couple of articles related to encryption topic in this forum and I feel that's really helpful I don't know if anyone has some knoeledge about the encryption issues in replication and clustering environment. I read some documents from Microsoft web site that explains how to move an encrypted database from its original server to another new server instance. That cause a lot manual works, if the database master key has been encrypted by the original service master key and you still want to enjoy the auto-open feature in the new environment. As we know the Microsoft SQL Server 2005 has a hierarchy encryption key structure and its top level service master key is really service oriented. For what kind of mechanism or set up, Microsoft makes their encrypted database working smoothly and automatically in a clustered and replicated infrastructure. Is that possible to sacrifice the security a bit by dump the service master key for database master key and make database more portable? I search the web site all the way, but couldn't find the related topic. Anybody has a good idea or experience to share?

SQL Server Admin 2014 :: Change Data Capture(CDC) For Data Warehouse / Reporting?

Aug 12, 2015

I have a requirement to implement CDC for 50+ tables to implement incremental data changes warehouse/reporting rather than exporting the whole table data. The largest table is having more than half a billion records.

The warehouse use a daily copy of OLTP db (daily DB refresh). How can I accomplish this. Is there a downside in implementing CDC just for the sake of taking incremental changes on the tables?

Is there any performance impact if we enable CDC on OLTP db?

Can we make use of the CDC tables on the environment we do daily db refresh so that the queries don't hit OLTP database?

What is the best way to implement CDC to take incremental changes for reporting.

Is RS2005's Matrix Data Region Feature Broken, Or Subject To Certain Limitations?

Dec 25, 2007

I'm consistently getting >10 minute render times in a matrix based report whose underlying query only takes 1-2 seconds to run in both RS's data tab and mgt studio. The bad render times occur in preview tab, Report Viewer and when requested from Report Manager. I believe most of the time being taken is RS's attempt to pivot and present the data.

I can run a homegrown query that pivots (with unknown number of cols) the data itself in under 4 seconds but would be concerned about mapping an unknown number of columns to a table region in RS.

The matrix I'm testing with is 67 columns across (just over 2 months of daily columns) and is supposed to be 207 rows long. There is no aggregation required by RS when it is pivoting the data because each intersection occurs at most one time in the query's result set. The number of data points actually being "bucketed" is around 13,800 values. Row headers consist of 3 columns.

RS is also cutting off the number of rows it is supposed to be showing. The number of rows cutoff seems to be 100% repeatable based on the date range chosen. RS doesnt tell me when it cuts off rows that should have been displayed. From what I can tell so far, it never cuts off columns.

The number of rows cut off seems consistent across designer's preview, report viewer and when requested thru report manager. The "run" command (exclamation icon in data tab) seems to always return the correct number of unpivoted rows, just as in mgt studio.

Are there known bugs and or limitations in RS's matrix data region feature? Are there some settings or workarounds that might make it work more to my liking?

SQL Server 2014 :: How To Copy Data Rows From Hosting To Local Server

I'm a web developer who writes transact-SQL to make my web applications run properly. I'm not real strong in other areas of SQL. Let me explain our set-up and then I'll explain what I want to do:

We have an ecommerce web site and all sales are saved in a SQL Server 2008 R2 database at our hosting company. We also have a local Windows 2012 network that has SQL Server 2014 Express installed.

Here is what I want to do:

I want to copy sales rows from the SQL Server 2008 database at our hosting company and save them in the SQL Server 2014 Express database on our local Windows 2012 server. I'd like to automate this if possible so that it happens each night perhaps. I know there is a way to schedule SQL jobs but I've never actually done this. I also would need to know how to attach to our hosting company DB as well as our local network DB.

SQL Server 2014 :: How To Import Data To Server From Access Database Using Script

Sep 22, 2015

I want to import the data from specific Access Database and Table to SQL Server, using SQL Script. I am trying to implement the solution as given in this link. URL....Here is the code that I have tried -

sp_configure 'show advanced options', 1;
sp_configure 'Ad Hoc Distributed Queries', 1;


The access database file path is - 'C:SQL ProjectTestDB1001.mdb'.The Table from which I want to import the data is - [Table1001]. but when I run this script, I get this error -9 The OLE DB provider "Microsoft.ACE.OLEDB.12.0" for linked server "MSAccessConnect" reported an error. Authentication failed.

Secondly I need to make 2 more changes to the code posted above.

1.If some access database .mdb, has got password protection, then how to include the password in the script, so that one does not have to manually feed in the password during data import work.

2. How to limit the data that is to be imported from the table [Table1001] by including a WHERE Clause, like for example - SELECT * FROM [Table1001] WHERE xdate = '2015-9-16 00:00:00.000')

Data Access :: Validation For Length Of The Character Data Types

Jun 10, 2015

I Have a table with #Sample like below

id int,
SSN varchar(20),
State varchar(2)
Sample Data:

1 999-000-000 AB
2 979-000-000 BC
3 995-000-000 CD

We used filter logic based on the SSN & State.

We are passing these values through variables like

Declare @State varchar(2)
Declare @SSN varchar(20)

While run time these values are lets suppose @SSN = '999-000-000' & @State='ABC'

Now the Result is displayed with the state data Like 'AB' only.

Output: 1 999-000-000 AB

instead it should give system generated error.

Here I have 2 Questions:
1. Why it is taking 1st 2 Charecters?
2. Why it does not have any system generated for length?

I can do validation with Length function for these 2 variables however if have 100 variables then it should not feasible case. So, what is the reason behind?
