Our Business partners request me to read the field names from a SQL table dynamically so that my SSIS package will not get impacted if Web Service hosts make a change.
Is there a way to evaluate a string at runtime that contains a field name ?
Thanks,

madhivanan asks for sample table data to avoid using a cursor. I could really use this, so here is the table
CREATE TABLE #T (
FORMULA VARCHAR(15),
ANSWER decimal(15,8)
)
INSERT INTO #T SELECT '1', NULL
INSERT INTO #T SELECT '1.0 + 2', NULL
INSERT INTO #T SELECT '1/2', NULL
INSERT INTO #T SELECT '1/2+2', NULL
INSERT INTO #T SELECT '1/(2+2)',NULL
INSERT INTO #T SELECT '3*7.5', NULL
INSERT INTO #T SELECT '3/2*.6-2', NULL
INSERT INTO #T SELECT '(1-1)', NULL
SELECT * FROM #T
-- RUN THE MATH FUNCTIONS, UPDATE THE TABLE'S ANSWER COLUMN WITH THE ANSWER
SELECT * FROM #T
DROP TABLE #T
I would expect this output:
FORMULA ANSWER
====================
1 NULL
1.0 + 2 NULL
1/2 NULL
1/2+2 NULL
1/(2+2) NULL
3*7.5 NULL
3/2*.6-2 NULL
FORMULA ANSWER
====================
1 1.00000000
1.0 + 2 3.00000000
1/2 0.50000000
1/2+2 2.50000000
1/(2+2) 0.25000000
3*7.5 22.50000000
3/2*.6-2 -1.10000000
(1-1) 0.00000000

Hi, I'm creating a dynamic SQL statement in MS SQL Server that is similiar to this:
EXEC('IF @' + @current_column + ' (SELECT ' + + @current_column etc...
I'm basically looping through a large list of parameters that correspond to column names. However, since SQL Server treats EXEC() as its own scope when it gets to what "@' + @current_column" evaluates to it says the parameter must be declared.
Is there a way to convert "@' + @current_column " into the actual value of the parameter?
We recently moved from v6.5 to v7.0. Now I have the databases and logs set to "autogrow". How can I monitor the disk space to ensure I do not run out of room (or is that preset as to how large it can grow ?). Can't find anything in the books online. Do I do this through the NT admin tool or through the SQL*Server Enterprise Manager and more importantly - how ???
Thanks so much for any help...

Why do I get an error message saying that the following expression won't evaluate?
"Select * from Price_grp where price_grp_id >= " + (dt_str, 10, 1252) @[User::MIN_PRICE_GRP_ID] +
" and " + (dt_str, 10, 1252) @[User::MIN_PRICE_GRP_ID] + " > 0"
Thanks for your help in advance.
I have been looking all over for some info about other people having this problem, but haven't found anything.
I have a package that needs to download a dated file from an ftp site. I am using a couple script objects to set variables, and one of them is the filename based on the date. I use an expression to get the date:
@[User::varFileName] = (DT_WSTR,4) Year( GetDate()) + (DT_WSTR,2) Month( GetDate()) + Substring((DT_WSTR, 29) GETDATE(), 9, 2)
Everything works really well when I am debugging it locally. However once it is on the server or even once I come back to it in a day or two, I am still seeing the old date. I thought it might be because my variable needed to be set to evaluateexpression = true, however once I did this it hung me and prevented me from debugging and I had to end bus dev studio. Not sure if its because it is being evaluated in two places (as a global and then in a script) but when I took it out of my script it hung again. Its strange in order to get it to work when I am debugging it locally I have to go to each process and evaluate the expressions in there, then it seems to work. thanks!
Hi all€”I'm new to expressions, and am trying to write one where I can evaluate if a field is null, to handle it by inserting a default value if a null value is found. Given this table definition:
CREATE TABLE [dbo].[Meter Readings_stage](
[Meter System ID] [varchar](8) NOT NULL,
[Reading Date/Time] [datetime] NOT NULL,
[Meter Status] [varchar](50) NULL,
[Totalizer] [float] NULL,
[Secondary Totalizer] [real] NULL CONSTRAINT [DF_Meter Readings_Secondary Totalizer2] DEFAULT (NULL),
[Demand] [real] NULL CONSTRAINT [DF_Meter Readings_Demand2] DEFAULT (NULL),
[Demand Date/Time] [datetime] NULL CONSTRAINT [DF_Meter Readings_Demand Date/Time2] DEFAULT (NULL),
[Reading Type] [varchar](30) NULL CONSTRAINT [DF_Meter Readings_Reading Type2] DEFAULT (NULL),
[Comments] [varchar](200) NULL CONSTRAINT [DF_Meter Readings_Comments2] DEFAULT ('None'),
[Checked?] [bit] NULL CONSTRAINT [DF_Meter Readings_Checked ?2] DEFAULT ((1)),
[Estimate Required] [bit] NULL CONSTRAINT [DF_Meter Readings_Estimate Required2] DEFAULT ((0)),
[Hold] [bit] NULL CONSTRAINT [DF_Meter Readings_Hold2] DEFAULT ((0)),
[Processed?] [bit] NOT NULL CONSTRAINT [DF_Meter Readings_Processed2] DEFAULT ((0))
I am importing data from a CSV file where any of the fields can be null. The format is as follows:
[Meter System ID],[Reading Date],[Reading Time],[Totalizer],[Demand],[Demand Date],[Demand Time], [Reading Type]
I need to handle it something like the following in a derived column transformation, where:
[Meter System ID]: string [DT_STR]
[Reading Date]: database date [DT_DBDATE]
[Reading Time]: database time [DT_DBTIME]
[Totalizer]: float [DT_R4]
[Demand]: float [DT_R4]
[Demand Date]: database date [DT_DBDATE]
[Demand Time]: database time [DT_DBTIME]
[Reading Type]: string [DT_STR]
This is what I have built so far:
NULL((DT_DBDATE)("Reading Date")) ? (DT_DBDATE)(GETDATE()) : (DT_DBDATE)("Reading Date")
I am getting an error on the cast conversion, however. Where is the error in the evaluation?
Thanks,
Jon
Hello all,
I currently have a pain in the butt with a subquery that needs to be evaluated, and if the result gives me a null value, I want to re-evaluate the condition and fill the column with the proper information.
I'll try to explain it as best as I can:
The query retrieves information from 2 tables basically, but i do need some inner joins of diferent tables in order to follow the relations..
I got 2 conditions that need to be acomplished, the 'typeof' (intId_Tipo) has to be diferent from 6 and a keycode equals to 3.
For the "general query" i do filter this just fine, but in the subquery is where I get stucked:
Since the evaluation that I do in oder to find the initial point is just by substracting 1, there are some cases where the type called intId_Tipo is actually 6 and the subquery returns me a null value.
In this particular case I want to substract 2..if not I just want to substract 1.
I added a SQL CASE in oder to evaluate the null value, but it is not evaluating properly, why? I'm not sure, I need your help and recomendation guys
Here's the query that I currently have: (the comments were made in order to take the next screenshot)
Code Snippet
SELECT --h.dt_Lectura,
--h.int_Velocidad, rp.int_VelMaxima,
(SELECT intpunto FROM tblRecorrido_Puntos WHERE intPunto = case when (intPunto) is null then rp.intPunto - 2 else rp.intPunto -1 END AND rp.intId_Ruta_Ramal =intId_Ruta_Ramal AND intId_Tipo =rp.intId_Tipo) as PuntoInicial,
rp.intPunto as PuntoFinal
--rp.strDescripcion_Punto as DescripcionPuntoFinal,
--1 as Contador
--a.idRuta_Guid, a.idRamal_Guid,a.idUnidad_Guid, a.idOperador_Guid
FROM tblHistorico h
INNER JOIN tblAsignaciones a
ON a.id=h.intIdAsignaciones
INNER JOIN tblRutaRamal_Generado rrg
ON rrg.id_Ruta = a.intRuta_Asignada
INNER JOIN tblRecorrido_Puntos rp
ON (rp.intId_Ruta_Ramal =rrg.intId_Ruta_Ramal AND rp.intPunto=h.int_PtoDest)
WHERE (
h.int_ClaveTDE =3 and rp.intId_Tipo <> 6
)
ORDER BY rp.intPunto ASC

Jaime,
I want to do some error checking on the parameters found in a SQLDataSource before I run the insert. The problem is these are ControlParameters and I want to do this dynamically so I can't just call the Control.Text property and grab its value. So how can I get access to what the ControlParameter evaluates to?
Secondly, is there a way to access what the update parameters evaluate to in order to check them before they're inserted - if so how do I get access to these?
Here's an example of one of the data sources i'm using:<asp:SqlDataSource ID="sqlContact" runat="server" ConnectionString="<%$ ConnectionStrings:strConn %>"
SelectCommand="SELECT [ContactID], [FirstName], [LastName], , [Address], [Phone], [Grade], [Contacted], [ListServe] FROM [Contact]"
UpdateCommand="UPDATE Contact SET FirstName = @FirstName, LastName = @LastName, Email = @Email, Address = @Address, Phone = @Phone, Grade = @Grade WHERE ContactID = @ContactID"
DeleteCommand="DELETE FROM [Contact] WHERE ContactID = @ContactID"
InsertCommand="INSERT INTO [Contact] ([FirstName],[LastName],,[Address],[Phone],[Grade],[Contacted],[ListServe]) VALUES (@FirstName,@LastName,@Email,@Address,@Phone,@Grade,0,0)">
<UpdateParameters>
<asp:Parameter Name="FirstName" Type="String" />
<asp:Parameter Name="LastName" Type="String" />
<asp:Parameter Name="Email" Type="String" />
<asp:Parameter Name="Address" Type="String" />
<asp:Parameter Name="Phone" Type="String" />
<asp:Parameter Name="Grade" Type="String" />
</UpdateParameters>
<InsertParameters>
<asp:ControlParameter Name="FirstName" Type="String" ControlID="txtContactFirst" PropertyName="Text" />
<asp:ControlParameter Name="LastName" Type="String" ControlID="txtContactLast" PropertyName="Text" />
<asp:ControlParameter Name="Email" Type="String" ControlID="txtContactEmail" PropertyName="Text" />
<asp:ControlParameter Name="Address" Type="String" ControlID="txtContactAddress" PropertyName="Text" />
<asp:ControlParameter Name="Phone" Type="String" ControlID="txtContactPhone" PropertyName="Text" />
<asp:ControlParameter Name="Grade" Type="String" ControlID="ddlContactGrade" PropertyName="SelectedValue" />
</InsertParameters>
</asp:SqlDataSource>
An Event is fired when I click add on a button which looks similar to this:
//Add btnAddContact_Clickprotected void btnAddContact_Click(object sender, EventArgs e)
{
InsertRow(sqlContact);
}The InsertRow() function is then what i'm using to evaluate the values... So how can get the values those controlparameters actually are in order to evaluate them before I actually insert. Or is there a better way to do it?
Hi
I'm updating an old Access application to SQL Server and am currently trying to decipher one of the reports on the old application. It appears to be evaluating a derived column from one query (qryStudentSuspGroup.Suspension) in the Select statement of another. I have tried to put the query that creates the derived column in as a nested query into the other query but can't get it to work. This is all a bit beyond my rudimentary SQL skills! Any help would be greatly appreciated!
The original Access SQL appears below:
SELECT [Enter the academic year (4 digits)] AS [input], ResearchStudent.Department, ResearchStudent.DateAwarded,
ResearchStudent.StudentNumber, Person.Forenames AS fore, Person.Surname AS Sur, ResearchStudent.Mode,
ResearchStudent.RegistrationDate, StudentExamination.Decision,
IIf(([Suspension]) Is Null Or [Suspension]=0,([DateAwarded]-[RegistrationDate])/365,(([DateAwarded]-[RegistrationDate])-([Suspension]))/365) AS CompDate,
ResearchStudent.EnrollmentCategory, qryStudentSuspGroup.Suspension
FROM ((ResearchStudent LEFT JOIN Person ON ResearchStudent.ResearchStudentID = Person.PersonID)
LEFT JOIN qryStudentSuspGroup ON ResearchStudent.ResearchStudentID = qryStudentSuspGroup.ResearchStudentID)
LEFT JOIN StudentExamination ON ResearchStudent.ResearchStudentID = StudentExamination.ResearchStudentID
WHERE (((Year([DateAwarded]))>=[Enter the academic year (4 digits)]
And (Year([DateAwarded]))<=([Enter the academic year (4 digits)]+1))
AND ((IIf(Year([DateAwarded])=[Enter the academic year (4 digits)],Month([DateAwarded])>8,Month([DateAwarded])<9))<>False))
ORDER BY ResearchStudent.Department, ResearchStudent.Mode, ([DateAwarded]-[RegistrationDate])/365
I have two int fields in my database, CEOAnnualBonus and CEOBonus, and I want to return the value of whichever one has the larger value as CEOBonusCombined. I thought using COALESCE would do the trick like below but there are many cases where either CEOAnnualBonus or CEOBonus have a zero value instead of NULL and it doesn't work.
SELECT
COALESCE(CEOAnnualBonus, CEOBonus)
AS CEOBonusCombined
FROM tbenchmarktemp
WHERE Ticker='F'

I'm just using TEXTBOX control to save data into my DB. My question is, if I have multiple lines of sentences, it does not store as what it looks like. For example;

It stores into the database as "Hello, Mike" and if I read from the database, it does not have seperate lines and shows it like this;
Hello, Mike
How can I store the contents into database and make the contents as original? (Sorry for the poor English, but I hope you understand it.)

View 2 Replies View RelatedHiI have developed a sql procedure for updating some xml content using SQL 2005 xQuery features.For example:Declare @xmlContent = '<books><book name="asp"/>< book name = "sql"/></books>'--Now I want to add attribute "book_id" to the xml content.SET @xmlContent.modify('insert attribute book_id{"1" } into (/books/book[@name="asp"])[1] ')SET @xmlContent.modify('insert attribute book_id{"2" } into (/books/book[@name="sql"])[1] ')SELECT @xmlContent--OUTPUT will be<books><book name="asp" book_id="1"/><book name="sql" book_id="2"/></books>QUESTIONQ1. Do we have any extension or plugin such that this SQl 2005 xquery feature can be incorporated in SQL 2000?Q2. If the answer for Q1. is no (as I expect), then do we have any TSQL feature in SQL 2000 for modifying xml content?I found all examples in SQl 2000 related with "openxml" function which performs the select kind of operations only. Like selecting data in XML format OR converting xml data in to tabular format. But I couldn't find any xml modification TSQL in SQl 2000 which can add element/attributes or change values.one workaround could be to consider xml content as string and use string functions to modify the content.But is there any more sensible approach available in SQL 2000?
View 1 Replies View RelatedOkay, moving to developing a small site that will be storing articles - that is a site largely consisting of html marked up articles with images. We already have an SQL Server so it is becoming the back-end.
So, since I'm not an SQL Server expert, some general advice on this would be appreciated? The articles, as I say in HTML (largely just markup for titles, and general text) would be stored in the DB? As Text datatypes?
How about the images...on disk or in SQL?
hi everybody,
The problem is, I have a table with one column of varchar(8000) datatype. It has got 1000's of records. Through Query Analyzer, I am not able to view my records after 257 columns in my table, even I increased my textsize by using 'set textsize' command.
Any other setting is available to correct this. Any help is appreciated.

I have a particular production database that on a few recent occasions has suddenly had one of it's tables empty of content. Now there are no jobs or triggers in place neither is any stored procedures that could perform a delete or alter table operation in place. The permissions have been set not to allow this either. The datatype is text only. What is intriguing is the QA server has an exact mirror and this dosen't happen. Has anyone come across this sort of phenomenon?
