Encrypting A Field In SQL Server 2000
Jul 20, 2006Hi,
I have a SSN field that I need to encrypt. Only persons who wants to get information about a user should be able to decrypt that field. What is the best way to encrypt and decrypt the ssn field? Thanks
T-SQL (SS2K8) :: Always Set A Field To NULL
Jan 26, 2015I would like to force a column to be null all the time. I cannot alter the table structure or alter the code that inserts data.
create table dbo.tblCustomer
(
CID int IDENTITY(1,1) not null,
Fnamevarchar(20) not null,
Lnamevarchar(20) not null,
Extravarchar(20) null
[Code] ....
So when this is executed the field Extra is always NULL
INSERT INTO tblCustomer (Fname, Lname, Extra)
VALUES ('bob', 'smith', 'ignore'), ('jane', 'doe', 'empty')
update dbo.tblCustomer set Extra = 'something'
If I've understood After triggers correctly the data will be written and the trigger will fire and overwrite. To avoid 2 writes
I could create an INSTEAD OF trigger
CREATE TRIGGER TR_I_Customer
ON tblCustomer
INSTEAD OF INSERT AS
BEGIN
SET NOCOUNT ON
INSERT INTO tblCustomer
(Fname, Lname, Extra)
SELECT Fname, Lname, NULL
FROM Inserted
END
This will not write the "extra" field twice. However if a new Nullable column were added; it would be v.easy to forget to update the Instead Of trigger. Everything would still work OK but I would be effectively ignoring the new column as well.
What I would like in the instead of trigger is do something like this...
UPDATE INSERTED SET Extra=NULL
Continue with insert without supplying column /value list.
What would be the best way of achieving this, trigger is the only way I could think of?
T-SQL (SS2K8) :: Update Field Value For Numbers Only
May 13, 2014Large design flaw, I know, but we have a table with a varchar field which contains alpha - numeric values. I need to change just the numerics, which can be in an position on the field:
Sample data of the field:
Rec1: Sally Morgan 201-555-1212
Rec2: 555-4040 John Smith
Rec3: Jane Houstin 201-555-6452 ext1223
Desired result:
Rec1: Sally Morgan 999-999-9999
Rec2: 999-9999 John Smith
Rec3: Jane Houstin 999-999-9999 ext9999
There's a bunch of UDFs out there for selecting just the numerics, but I'm having trouble throwing it into a viable script for repeatable execution.
T-SQL (SS2K8) :: Case For Field Type
Jun 7, 2014Is there an easy way to send back to my C# program the pascal case of a field type? If you get the parameters or columns for a table or procedure the type is in all lowercase (varchar instead of VarChar). But in C#, it is in an enum (SqlDbType) that has the variables as mixed case so you can't compare them and just pass the type. You need to figure out what the case should be - varchar should be VarChar and bigint should be BigInt.

T-SQL (SS2K8) :: Field Has No Value But Is Not NULL Or Empty?
Aug 13, 2015I added a new field to an existing ETL process which uses SSIS to ingest a CSV file. The new field in the file, Call_Transaction_ID, will not always be populated for every record and so can be NULL or empty for certain records.
Here's the problem:After the file is extracted into a staging table, the Call_Transaction_ID field is showing blank or empty when it has no ID for that particular record. The problem is when I try to then ETL this data into a fact table - I'm trying to set the Call_Transaction_ID field to -1 if it is NULL or empty, however SQL Server doesn't see the field as empty even though there is no value in the field so -1 will NEVER return.
Using a WHERE DATALENGTH(Call_Transaction_ID) = 0 returns 0 records, again because SQL Server doesn't see the field as empty or NULL.
What do I do now to get around this? How do I fix it?
T-SQL (SS2K8) :: Comparison Of Times In Same Field
Sep 22, 2015I'm looking for comparing times in the same field. I have two tables, one table has times of sessions (multiple rows) and the other contains the session ID, start & end times of overall session block and each session length. I am looking for a way to compare from the start of the session until the end all the times sequentially and insert or mark all the sessions that fall between 10 min intervals.
i.e start 10:30 compare to 10:35 (no match), 10:30 to 10:40 (match 10:40 becomes new effective date), 10:40 to 10:45 (no match), 10:40 to 10:50 (match 10:50 new effective date).
I've attempted a couple of self join solutions but simply can't seem to get what I'm after.
CREATE TABLE MyTable (
[id] INT identity NOT NULL,
[sess_id] INT NOT NULL,
[Time] datetime NOT NULL
)
GO
[Code] .....

T-SQL (SS2K8) :: Using Not Like To Filter Out Non-numeric Values From Varchar Field
Mar 26, 2014I am putting a SELECT statement together where I need to evaluate a results field, to determine how the color indicator will show on a SSRS report. I am running into a problem when I try to filter out any non-numeric values from a varchar field, using a nested CASE statement.
For example, this results field may contain values of '<1', '>=1', '1', '100', '500', '5000', etc. For one type of test, I need a value of 500 or less to be shown as a green indicator in a report, and any value over that would be flagged as a red. Another test might only allow a value of 10 or less before being flagged with a red.
This is why I setup a CASE statement for an IndicatorValue that will pass over to the report to determine the indicator color. Using CASE statements for this is easier to work with, and less taxing on the report server, if done in SQL Server instead of nested SSRS expressions, especially since a variety of tests have different result values that would be flagged as green or red.
I have a separate nested CASE statement that will handle any of the values that contain ">" or "<", so I am using the following to filter those out, and then convert it to an int value, to determine what the indicator value should be. Here is the line of the script that is erring out"
case when (RESULT not like '%<%') or (RESULT not like '%>%') then
CASE WHEN (CONVERT(int, RESULT) between 0 and 500) THEN '2'
ELSE '0'
The message I am getting is: Conversion failed when converting the varchar value '<1' to data type int.
I thought a "not like" statement would not include those values for converting to an int, but that does not seem to be working correctly. I did also try moving the not to show as "not RESULT like", and that did not change the message.
How I can filter out non-numeric values before converting the rest of the varchar field (RESULT) to int, so that it is only converting actual numbers?
T-SQL (SS2K8) :: Error Altering Field Spec In A Table
Apr 18, 2014I have a db1.tPersonJobHist where I have two columns
[WorkflowCoordinatorFlag] [dbo].[shrsFlag] NOT NULL,
[HRBusinessPartnerCode] [dbo].[shrsCode] NULL,
Our developer mistakenly made HRbusinesspartnercode field as nullable. He now wants to change it to Not Nullable.
So there were 4 rows where the values were not null(not sure how). We edited those rows and changed those values to NUll. Now we have no Nulls in that column.
So we brought up the table designer and made the change but got the following error
'tPersonJobHist' table
- Unable to modify table.
Cannot insert the value NULL into column 'HRBusinessPartnerCode', table 'BD6578.dbo.Tmp_tPersonJobHist'; column does not allow nulls. INSERT fails.
The statement has been terminated.
Question is why wouldn't it let me alter the table design. and what is tmp_tpersonjobhist.?
How can I make this column Not-nullable.

T-SQL (SS2K8) :: Substitute Hour Part Of Datetime Field?
Apr 27, 2015I have a table with a datetime field (named "lnDateDone") and an integer field (named "PlannedHour"). I want to build a new datetime field with the same value as lnDateDone and replacing the hour part by the PlannedHour field. Example:
lnDateDone = '2014-04-09 13:22:31.544'
HourPlanned = 14
new datetime field = '2014-04-09 14:00:00'
I tried the following:
CAST(SUBSTRING(CAST(lnDateDone AS VARCHAR(25)),1,12) + CAST(PlannedHour AS VARCHAR(2)) + SUBSTRING(CAST(lnDateDone AS VARCHAR(25)), 15, LEN(lnDateHeureFin)) AS SMALLDATETIME) AS DatePrevue
but it won't work when casted in DateTime format, only in varchar, but I want it in datetime as I need to do compute some values using date manipulation functions.
How can I do that?
T-SQL (SS2K8) :: Update A Field In 3rd Table From 2 Joined Tables

T-SQL (SS2K8) :: Detect / Determine Data Stored In Varbinary Field
Oct 21, 2014I have several tables a varbinary column in a database. They have names like CSB_BLOB or OBJECT_BLOB. Now I am having intermittent success with getting the data out.
For example this query returns readable text from this data.
0x46726F6D3A20226465616E6E6167726.....etc --data as stored in the column
SELECT CAST(CSB_BLOB AS VARCHAR(MAX)) AS 'Message' FROM OBJECT_BLOB
However this column has the following query results.
0x0001000000FFFFFFFF01000000000000000C....etc. --data as stored in column
--this query returns empty result
SELECT (CSB_BLOB AS VARCHAR(MAX)) AS 'Message' FROM CSB_STATUS_LOG
--this query returns no change???
SELECT CONVERT(VARCHAR(MAX), CONVERT(VARBINARY(MAX), CSB_BLOB, 2), 2) FROM CSB_STATUS_LOG
0001000000FFFFFFFF01000000000000000C....etc
Obviously there is a difference between the two but I am not educated enough to interpret this difference. What do I need to learn / read so I can look at the data in one of these BLOB columns and know how to convert it to something meaningful?
Something like:
1. Try to cast as varchar to see if it is text.
2. Turn into a byte array and see if it is a jpg
3. Turn into a byte array and see if it is a pdf
4. Convert it to hex and then cast as varchar
5. etc....

T-SQL (SS2K8) :: Arithmetic Overflow Error Converting Varchar To Data Type Numeric Message When Field Is Decimal
Apr 3, 2014I am trying to setup an indicator value for an SSRS report to show green and red values on a report, based on the NRESULT value. The problem I am facing is that I have several different CASE statements that have the same logic, and they are processing just fine. NRESULT is a decimal field, so no conversion should be necessary. I do not know why I am getting the "Arithmetic overflow error converting varchar to data type numeric." error message.
Below is the CASE statement where the error is occurring. It is in the part of the ELSE CASE. The first CASE works just fine when the ELSE CASE is commented out. If I also change the ELSE CASE statement to say "else case when LEFT(NRESULT,1) = '-' then '0'", then it processes fine, too, so it has to be something I am missing something in the check on negative values. I do need the two checks, one for positive and one for negative values, to take place.
case when LEFT(NRESULT,1) <> '-' then --This portion, for checking positive values, of the CASE statement works fine.
CASE WHEN LEFT(ROUND(NRESULT,2),4) between 0.00 and 0.49 THEN '2' --Green
ELSE CASE WHEN LEFT(ROUND(NRESULT,2),4) > 0.49 THEN '0' --Red
ELSE '3' --White
END
END
else case when LEFT(NRESULT,1) = '-' then --This portion, for checking negative values, of the CASE statement is producing the conversion error message.
[code]....
I checked the NRESULT field, and there are not any NULL values in there, either.

Encrypting Data
May 4, 2004I have an application that has stores sensitive data in an SQL server and I am currently handling this through my ASP.NET application using the encryption classes in C#.
One of the things we would eventually like to be able to do is use other programs (like Microsoft Access) to run advanced Querys on the tables and retrive the data. With the encyption being done in C#/ASP all that would be returned would be the encrypted data.
I wondering if there is a way to build a layer to encrypt/decrypt data at the database level, my searches haven't yeiled to much info (As well as a trip to Borders) as I haven't seen any books that even touch on this.
I don't know a lot about SQL right now (Mainly only MySQL so Stored Procs and all that stuff are really new to me) so I don't know if I would go about it this way or not? (Using a stored procedure)
Can anyone reccommened where I should start to learn about accomplishing this? Books are usually the best help but I'll take any kind of information that can be thrown my way :-)
Thanks!
