Index In Calculated Field From A Ntext Field
Nov 8, 2005
For some reasons I have to use a ntext field for both small strings like "10" and large binalry files.
I need to sort the field to some extend to present the small strings on a sorted nice way - answers to " What country are you from" etc.
To trick the sorting I use a calculated field:
ORDER BY RSort - where Rsort is:
convert(varchar(4), RD.response) as RSort
It works but put a high load on the SQL server when the number of responses increases.
I though of making a non clustered index based on the calculated field, but is not sure that it will work as intended.
What do I do. The last thing would be to change the ntext to vchar(3800) or something like that. :confused:

I'm using DTS to import data from an Access memo field into a SQL Server ntext field. DTS is only importing the first 255 characters of the memo field and truncating the rest.I'd appreciate any insights into what may be causing this problem, and what I can do about it.Thanks in advance for any help!

Hello All,
Maybe a stupid question but I'm new to the db admin work so please bear with me.
I've imported an Access db into SQL, in the Access db the field type was 'memo' to accomodate the large amount of text (on avg ruffly 4100 chars. with spaces). Now in SQL the field in the table I have set up as an ntext field, which I understood to be equivalent to a memo field in Access.
My problem is when saving data to the field the first time it saves all the data correctly with the exception of the field in question. The data in the field is '<LongText>', now when I try to update the data in the table I get a 'Data Truncated' error message and no update takes place throughout the table.
After testing this and trying different things, I've found that if I shorten this one field and try to save to the db I still get the 'Data Truncated' error message. If I shorten the data in the field AND delete the record from the SQL table then it will save just fine from there on out (which won't work for the reports).
I'm not sure what I'm missing here to get this to work the way it did in Access.

Hi All,
I will be doing stress test for my app.
Loading thousands of records to the DB through bulk insert.
There's one field NText which I have left NULL because it will be hard to gen dummy flat file to it.
I have another table which has the Ntext Value which i will want to copy and duplicate to the other table.
what is the way to do it?
simply said i want to update a record with NULL value from one table with NText field with the value from another table..

I'm trying to parse an ntext field that in my SQL View contains an invoice comment in order to be able to group on parts of the comment. I have two problems--one, the syntax to do this, and two, the best way to deal with the parts that I want.
The comment is like: "standard text ABCDE : $99.99" but can have multiple "ABCDE"s, e.g. "standard text ABCDE FGH IJKL $999.99" and I found some that had duplicates like "standard text standard text...".
I want to be able to report in SSRS 2005 by grouping the "ABCDE", "FGH", "IJKL" items.
Any ideas? Please be specific as I'm still learning.

I am a newbie to SQL Server using SQL Server 2000.
I am trying to use a calculated field in a table, what I want is for the result to be shown as an integer (int)?
However the fields that I base the calculation on are of the type (money), and the calculted field although giving me the correct result makes the field of type (money).
The fields that I am basing the calculation on are:-
ColumnName Type Size Allow Nulls
PurchasePrice money 8 0
LoanSize money 8 0
this is the code for the calculated field
([loansize] / [PurchasePrice] * 100)
and this is the description of the calculated field that is forced in the designer
ColumnName Type Size Allow Nulls
LTV money 8 1
and the designer does not allow me to change the type.
I would be grateful of any pointers
Regards
Tony

I have the following fields in table A:
GL_ID|GL_Name_VC| Amount |Period_TI|Year_SI
===================================================
1000|liability | -10,000.00 | 08 | 2005
===================================================
1001| asset | 20,000.00 | 08 | 2005
===================================================
1000|liability | -9,000.00 | 09 | 2005
the fields above have the following datatype:
Fields | Datatype
===================================
GL_ID | Integer
GL_Name_VC | Variable Character
Amount | Integer
Period_TI | TinyInteger
Year_SI | SmallInteger
The above database is running on Microsoft SQL Server 2000 and i would like to query
for a report that looks something as below:
Description Amount
asset 20,000.00
liability (10,000.00)
===========
Net Asset 10,000.00
===========
The above report would list 2 columns as Description & Amount, next it would sort the Description
column by GL_ID, next by Year 2005 & lastly by Period 08, with a net figure of asset minus liability.
Guys, hope someone out there can help me with the sql command for the above report?

My Stored Proc runs through a loop and concats the contents of each field into one big nvarchar. Procedure works fine on a smaller scale but now it is being implemented on a very large table and the results of the sequel overflow the nvarchar limits. I looked into using text and ntext but both cannot be declared locally. Does anyone know how I can work aroudn this limitation?
Summary:The problem is that the temporary variable I am using (nvarchar) is too small to contain the robust size that the SQL is concating into it. The final field it winds up in is a text field and will be able to handle the amount of data, its just getting the data there is the issue..... Your thoughts please....

I am used to working in MS Access where you can return a value as in:
[date1]-[date2]=X
It will calculate that value provided "date1" and "date2" are fields in the recordset. One calc for each record.
I am getting an error message in SQL Server saying that neither "date1" nor "date2" are not contained in an aggregate function and there is no "group by" clause.
In Access this would not be a problem.
Can you help?
Thank you.

Right now I have one view that grabs records and sums up related records etc.... and returns a result. So basically it has the ID number and the number I calculated. THen I have another view that takes that number and performs calculations on it into three different columns. Is there any way to make these two view into one without a lot of repetative statements? Here is an example:
SELECT (tblTest.Quantity * tblTest.Price) as SubTotal, SubTotal * 1.06 as Total
Obviously that doesn't work, but what could I do to get that basic thing to work?
Thanks!

I have a Vehicle/Driver Inspection Database and I'm trying to create a Traffic Violation Point System, its a system when drivers commit certain traffic offences they will incur driving-offence points.
System: The points for violations that all occurred within the last 12 months of ONE ANOTHER are added together to calculate point total. If the accumulated points is reached 14 points driver is suspended the points will be REMOVED or minus 14 points after the suspension has been served.
Example:
Date of Offence - Number of Points
Aug. 6, 2013 - 6
Feb. 4, 2014 - 4
Apr. 25, 2014 - 4
- 2
May 8, 2014 - 2
Explanation:
On April 25, 2014 two offences incurred and from (Aug 6, 2013 - Apr. 25 2014) 14 points have accumulated (6 + 4 + 4) and suspension is carried out then 14 points is removed. The 2nd offence on Apr. 25, 2014 will be carried forward and added to May 8, 2014 points (total 4 points).
Below are DB Tables:
tbl_Driver
DriverID DriverLicense FirstName LastName
tbl_Event
EventID EventTIme DriverID CarID
tbl_EventViolation
EventViolatinID EventID ViolationID Status (1 = no, 2 = yes radio buttons)
tbl_Violation
ViolationID ViolationName Points
tbl_ViolationClass
ViolationClassID ClassName
I made an SQL Code but to sum the accumulated points only but not the whole condition. See below:
SELECTa.DriverId,
a.DriverLicense,
a.FirstName + ' ' + a.LastName as DriverName,
a.FirstName,
a.LastName,
a.DriverMobileNo1,
[Code] .....

Hi I am having a problem with something that was relatively simple in Crystal and i am guessing it is purely my inexperience that is the issue here!
Calculated Field
=iif(Fields!Fun_Debt_Status.Value <> "debt","",
iif(max(Fields!Fun_Days_Overdue.Value)>30,"On Stop",
iif(max(Fields!Fun_Days_Overdue.Value)>0,"Overdue",
iif(sum(Fields!Fun_OS_Amount.Value)> Fields!CREDIT_LIMIT.Value,"Over Credit Limit","ok"))))
Want i am trying to do as you can probably see is create a "Account Status" field depending upon overdue days for payment etc..
My report just produces an error (internal) when i try and run - the calculated field above isn't even on the report.
Please let me know what i am doing wrong! I maybe going at it in completely the wrong way altogether,
Thanks in Advance!

I am having an interesting error. I have a bunch of data that I am updating to a field in my sql server 7.0 database. It updates the data, however only puts the first 64,999 characters into the field. The datatype is ntext. From what I understand, ntext datatype can hold much more than 65,000 characters. Am I right in this? The data I'm putting into the field is html tags/text. I've tried several different data sets. I'm updating the data using Coldfusion/SQL commands.
Here is my SQL syntax:
UPDATE htmltest
SET html_offline = '#form.html#'
WHERE htmlid = #form.htmlid#
