Encrypting SQL Server Table Columns
Jun 28, 2006
I have never used any type of encryption for SqL Server 2000, but I have recently been asked to research what would be involved to encrypt data like social security numbers.
Since I have no idea where to begin, I was wondering if someone could point in the right direction? Do I need to buy a third party tool to perform this, are security certificates involved? Overall, I need information on everything that I need to encrypt data using SQL Server 2000, and How to perform the tasks!!!
Thank You!

Here is My requirement, I'm not sure if this is possible. Creating table called master like col1, col2 col3, col4 , col5 ...Where Col1, col2 are updatable - this can be done easily
Col3, col4 are columns in another table but these can be just a read only ?? Is this possible ? this is possible with View but not friendly with share point CRUD...Col 5 is a computed column of col 2 and col5 ? if above step can be done then sure this can be done I guess.

I support an accounting application that uses SQL as the db engine. One of our clients is asking about encrypting of certain data within the database. The developer does not encrypt the data nor have they any plans to. My question is, can we turn on encryption of a field in one of the data tables that will not require decryption by the accounting application. In other words, if we set encryption at the db level, can the server itself decrypt the data when it's called by the application? Or does the application have to do the decryption?
Thanks in advance and please excuse my ignorance.

So I have been trying to get mySQL query to work for a large database that I have. I have (lets say) two tables Table_One and Table_Two. Table_One has three columns: Type, Animal and TestID and Table_Two has 2 columns Test_Name and Test_ID. Example with values is below:
**TABLE_ONE**
Type Animal TestID
-----------------------------------------
Mammal Goat 1
Fish Cod 1
Bird Chicken 1
Reptile Snake 1
Bird Crow 2
Mammal Cow 2
Bird Ostrich 3
**Table_Two**
Test_name TestID
-------------------------
Test_1 1
Test_1 1
Test_1 1
Test_1 1
Test_2 2
Test_2 2
Test_3 3
In Table_One all types come under one column and the values of all Types (Mammal, Fish, Bird, Reptile) come under another column (Animals). Table_One and Two can be linked by Test_ID
I am trying to create a table such as shown below:
Test_Name Bird Reptile Mammal Fish
-----------------------------------------------------------------
Test_1 Chicken Snake Goat Cod
Test_2 Crow Cow
Test_3 Ostrich
This should be my final table. The approach I am currently using is to make multiple instances of Table_One and using joins to form this final table. So the column Bird, Reptile, Mammal and Fish all come from a different copy of Table_one.
For e.g
Select
Test_Name AS 'Test_Name',
Table_Bird.Animal AS 'Birds',
Table_Mammal.Animal AS 'Mammal',
Table_Reptile.Animal AS 'Reptile,
Table_Fish.Animal AS 'Fish'
From Table_One
[Code] .....
The problem with this query is it only works when all entries for Birds, Mammals, Reptiles and Fish have some value. If one field is empty as for Test_Two or Test_Three, it doesn't return that record. I used Or instead of And in the WHERE clause but that didn't work as well.

Hello,
I've been using SSIS for a while and think I get the gist of how it works (and it works nicely!).
However, because of the configuration on my machine I am constantly moving the dtsx files around (long story). Sometimes I make a full image backup and then later restore those SSIS packages.
The problem is that even if I copy the dtsx files to a different directory and then copy them back (without making any changes) I get a 'Cannot Aquire Connection' message. Other times I get errors that have to do with the encryption of the individual package. For those, I just reset the package to save with a password, save it, and then reopen it and can resave it again with the userkey encryption. This one occured when I move the packages from one machine to another.
Is there a best (or at least good) way to save packages with the sensitive data that won't force me to reconfigure it each time I move a package around? Or have to enter passwords each time?
Also, what is the advantage of saving the files in SQL Server? I assume you are not actually saving the files, just the data about them. I just don't understand it enough to even ask an intelligent question about it.
Thank you for the help.

Right-clicking "Protocols for MSSQLSERVER" under the Sql 2005 Server Configuration Manager I
find the "Force Encryption" option. Right-clicking the SQL Native Client Configuration, Client Protocols,
I find "Force Protocol Encryption"
I believe these can be used together to force the connection between a client (running the SQLNC client) and a sql 2005 server to be encrypted. In other words, the data "in motion" can be encrypted.
1. Is my understanding correct?
2. Do I need to use a certificate to make this work?
TIA,

Hi All,
I have the following requirement. I need to store the password for the connection manager in the configuration file. The sink for the configuration file is SQL Server. Though the password field appears as "******" the actual value is being taken as ""******" itself. If i update the SQL server table with the correct value, then the package starts working. But, the password is shown as clear text.
If i write logic to encrypt the password column in the configuration table, is there a way to tell the SSIS execute engine to decrypt the password before using the same for making the connection.
Is there a place holder, where i can write the decrypt code so that the decrypted password can be sent to the execution engine?
Thanks In Advance,
Madhu

I just created a new table with over 100 Columns and I need to populated just the first 2 columns.
The first columns to populate is an identify column that is the primary key. The second column is a foreign_key to an other column and I am trying to populate this columns with all the values from the foreign_key value. This is what I am trying to do.
column1 = ID
column2= P_CLIENT_D
SET IDENTITY_INSERT PIM1 ON
INSERT INTO PIM1 (P_CLIENT_ID)
SELECT
Client.ID
FROMP_Client
So I am trying to insert both an identity values and a value from an other table while leaving the other columns blank. How do I go about doing this.

Hi,
I have two tables
Table Source
{
category varchar(20),
LastUpdate datetime
}
Table Destination
{
SubjectId varchar(20),
SubjectDate datetime,
category varchar(20),
LastUpdate datetime
}
Please note that the number columns are different in each table.
I wanted to dump the data of Source table to Destination table. I meant to say that the rows of 2 columns in Source table to last 2 rows of Destination table.
And also my oreder of the columns in Destination table will vary. So i need to a way to dynamically insert the data in bulk. but i will know the column names for sure before inserting.
Is there anyway to bulk insert into these columns.
Your quick response will be appreciated

I have a business need to create a report by query data from a MS SQL 2008 database and display the result to the users on a web page. The report initially has 6 columns of data and 2 out of 6 have JSON data so the users request to have those 2 JSON columns parse into 15 additional columns (first JSON column has 8 key/value pairs and the second JSON column has 7 key/value pairs). Here what I have done so far:
I found a table value function (fnSplitJson2) from this link [URL]. Using this function I can parse a column of JSON data into a table. So when I use the function above against the first column (with JSON data) in my query (with CROSS APPLY) I got the right data back the but I got 8 additional rows of each of the row in my table. The reason for this side effect is because the function returned a table of 8 row (8 key/value pairs) for each json string data that it parsed.
1. First question: How do I modify my current query (see below) so that for each row in my table i got back one row with 19 columns.
SELECT A.ITEM1,A.ITEM2,A.ITEM3,A.ITEM4, B.*
FROM PRODUCT A
CROSS APPLY fnSplitJson2(A.ITEM5,NULL) B
If updated my query (see below) and call the function twice within the CROSS APPLY clause I got this error: "The multi-part identifier "A.ITEM6" could be be bound.
2. My second question: How to i get around this error?
SELECT A.ITEM1,A.ITEM2,A.ITEM3,A.ITEM4, B.*, C.*
FROM PRODUCT A
CROSS APPLY fnSplitJson2(A.ITEM5,NULL) B, fnSplitJson2(A.ITEM6,NULL) C
I am using Microsoft SQL Server 2008 R2 version. Windows 7 desktop.

Say you have a fact table with a few columns that all reference the same key column in a dimension table, you want to write a view to return the information for those keys?
USE MyTestDB;
GO
SET NOCOUNT ON;
IF OBJECT_ID ('dbo.FactTemp' ,'U') IS NOT NULL
DROP TABLE dbo.FactTemp;
[Code] ....
I'm using very small data at the moment, and the query plan and statistics don't really say which way.

I have a web interface where i have listing of several data and check box for inserting data into SQL server 2005 database table,
so I am able to inset data to sql tables using stored procedure. Now the question is i want to update these inserted records(agency approval column inserted as 1) in same table and assign value 1 fot the checked data to column finace approval as 1.
Here is how ia have webclas library where i script for getting the insert parameterspublic void Process_Payment(ref DataTable TableWithPayments, string Payment)
{SqlCommand InsertCommand = new SqlCommand();
SqlConnection AccessDatabase = new SqlConnection(FinanceSourceWrite.ConnectionString);int PaymentID = 0;
AccessDatabase.Open();
InsertCommand.Connection = AccessDatabase;
//DataTable TemporaryTable = new DataTable();
//TemporaryTable = TableWithPayments;SqlTransaction TransactionProcess = null;
SqlParameter InsertParameters;foreach (DataRow DataCommentInfo in TableWithPayments.Rows)
{InsertCommand.CommandText = "InsertPaymentList"; //THIS IS my stored procedureInsertCommand.CommandType = CommandType.StoredProcedure;
TransactionProcess = AccessDatabase.BeginTransaction();
// SET ALL THE VALUES FOR THE PARAMETERSInsertParameters = InsertCommand.Parameters.Add("@JC_ID", SqlDbType.Int);
InsertParameters.Direction = ParameterDirection.Input;InsertParameters.Value = DataCommentInfo["JC_ID"];
InsertParameters = InsertCommand.Parameters.Add("@Payment_Type", SqlDbType.Int);
InsertParameters.Direction = ParameterDirection.Input;InsertParameters.Value = DataCommentInfo["Payment_Type_ID"];
InsertParameters = InsertCommand.Parameters.Add("@Agency_approval", SqlDbType.Int);InsertParameters.Direction = ParameterDirection.Input;
InsertParameters.Value = DataCommentInfo["Agency_approval"];
Now my stored procedure
ALTER PROCEDURE [dbo].[InsertPaymentList](
@JC_ID int ,
@Payment_Type int,
@Payment_Group int,
@AGENCY_ID int,
@Agency_approval int,
@Agency_approval_date datetime,
@Program_ID nvarchar(50),
@Status bit,
@Jobsite_code_ID int,
@Date_Stamp datetime,
@Provider nvarchar(50),
@UserName nvarchar(256),
@Activity_ID int,
@Subproject_ID int,
@Payment_Support_Retention_List_ID int,
@WPR_ID int,
@Placement_ID int,
@Enrollment_ID int,
@Satisfaction_ID int,
@Enrollment_Bonus_ID int,
@Re_Placement_Bonus_ID int
)AS
INSERT INTO Payment_LIST_AIMS
(JC_ID, Payment_Type, Payment_Group, AGENCY_ID, Agency_approval,
Agency_approval_date, Program_ID, status,
Jobsite_code_ID, Provider, UserName, Placement_ACTV_ID, Placement_Sub_ID, Support_Retention_ID, WPR_ID, Placement_ID,Enrollment_ID,Satisfaction_ID,Enrollment_Bonus_ID,Re_Placement_Bonus_ID)
VALUES @JC_ID, @Payment_Type, @Payment_Group, @AGENCY_ID, @Agency_approval,@Agency_approval_date, @Program_ID, @Status,
@Jobsite_code_ID, @Provider, @UserName, @Activity_ID,
@Subproject_ID, @Payment_Support_Retention_List_ID, @WPR_ID, @Placement_ID,@Enrollment_ID,@Satisfaction_ID,@Enrollment_Bonus_ID,@Re_Placement_Bonus_ID)
SELECT CAST(scope_identity() as int)
Here like you see agency approval column in SQL server table gets value assigned as 1 when Agency user clicks the confirm payment button and so all the values as above....
Now another user Finance user process the same records from the web UI and clicks the process payment button at this stage ..i need to update Finance approval column as 1 agains that particular record existing th the SQL table, there are two three coulmc to be updated , Finance approval(this is where i need help) , Finance approval date , and user
Being a newbie please help me whith how i can fix this
Thanks

I am planning to add some new columns to an existing sql server 2012 table. I know that I need to use the alter statement to accomplish this goal. However my questions is the location of where I want to add the new columns to the table. It would make more sense to add the new columns to the middle of the table since these columns have a similar meaning as other columns in the middle of the table.
However is it better to add these new columns at the end of the table? I am asking this question since I am thinking I might need some sql to move the values of existing columns and values around?
Thus is it better to add new columns to a table in the middle of the table, at the end of the table, or at the end of the table? If so, why one location is better than another location?

I have two tables: "Users" and "Messages".
The Messages table has a "UserFromID" and an "UserToID", indicating a message was sent from a user to a user.
The Users table has a UserID, FirstName, LastName and UserGroup.
Im trying to get all messages sent by or to a user in a specific group, with the First and Last names of the sending and receiving users.
Here is my tables and data:
CREATE TABLE tmp_users (userID INT, GroupID INT, UserName VARCHAR(10), FullName VARCHAR(100))
CREATE TABLE tmp_Messages (aKey INT IDENTITY, FromUserID INT, ToUserID INT, msg VARCHAR(100))
INSERT INTO tmp_users VALUES (1,1,'John','John Smith')
INSERT INTO tmp_users VALUES (2,1,'Jane','Jane Doh')
INSERT INTO tmp_users VALUES (3,1,'Bob','Bob Newheart')
[code]....
The query Im running so far is wrong, but here it is...
SELECT t.FromUserID, t.ToUserID, t.msg, u.UserName AS UserFrom,
u.GroupID AS FromGroup, u2.UserName AS UserTo, u2.GroupID AS ToGroup
FROM tmp_Messages t
LEFT JOIN (SELECT UserID, GroupID, UserName FROM tmp_users WHERE GroupID = 3) u
[Code] .....
im missing the details of one of the users.I know what the problem is, I just cant figure out how to get this working without using temp tables, which I cant do in the production version.

I have multiple databases in the server and all my databases have tables: stdVersions, stdChangeLog. The stdVersions table have field called DatabaseVersion which stored the version of the database. The stdChangeLog table have a field called ChangedOn which stored the date of any change made in the database.
I need to write a query/stored procedure/function that will return all the database names, version and the date changed on. The results should look something like this:
DatabaseName DatabaseVersion DateChangedOn
OK5_AAGLASS 5.10.1.2 2015/01/12
OK5_SHOPRITE 5.9.1.6 2015/01/10
OK5_SALDANHA 5.10.1.2 2014/12/23
The results should be ordered by DateChangedOn.

Is there a good way to add columns to a table type?
I built several procs which make use of table-valued-parameters, and they work pretty nicely, until I need them to accept additional columns. Then I have to drop all the procs that use them, alter the types, and rebuild all the procedures, which is a huge pain in the rear.
Is there any good way (built in, or custom) to alter the def of a table type that's used as a parameter to multiple stored procedures?

I have a table with 8 columns, I need to update data in multiple columns on this table, this table contains 1 million records, having single update was taking time so I broke the single update into multiple update statements and running multiple update statements in parallel, Each update statement updates different column.
This approach is working fine but I am getting the deadlock error.
Transaction (Process ID 65) was deadlocked on lock | communication buffer resources with another process and has been chosen as the deadlock victim. Rerun the transaction.
I tried with various lock hints but no success.

I am trying to produce a query result that will be using a Case statement to determine values based on scores in a table for each row. The result needs to be exported to be used to upload to a state reporting website. My problem is that the state requires in the CSV file that is uploaded a lot of fields that we do not actually have in the database table we are creating the result set from. After I receive my result set using the Case statement, is there a way to add additional columns that don't actually exist in a table so I can export directly from SQL?

DECLARE @columns NVARCHAR(MAX), @sql NVARCHAR(MAX);
SET @columns = N'';
SELECT @columns += N', p.' + QUOTENAME(deck)
FROM (SELECT p.deck FROM dbo.report AS p

I have a table (we will cal DateTable) with several (20) columns, each being a date type. Another table's (Project) PK is referenced in the DateTable.
I am trying to write a query that will pull all dates for a specific project from the DateTable if they meet certain criteria(i.e. if the date is <= 7 days from now.
I started with a normal select statement selecting each column with a join to the project and then a where clause using
(DateTable.ColumnName BETWEEN GETDATE() AND DATEADD(day, 7, GETDATE()) OR (DateTable.ColumnName BETWEEN GETDATE() AND DATEADD(day, 7, GETDATE())) ...
The rest of the columns(all with OR between them).
The problem with this is that because I am using OR once one of the dates meets the criteria it selects all the dates that are associated with the project. I ONLY want the dates that meet the criteria and don't care about the rest.
Obviously because I have all the columns in the select statement... So I need something like
Select ALL Columns
from DateTable d
Join Project p
where p.ProjectID = d.ProjectID AND only dates BETWEEN GETDATE() AND DATEADD(day, 7, GETDATE()))
