Specified Cast Is Not Valid

Can't seem to find why I'm getting this error: Specified cast is not valid.

Ok, using a stored procedure for SQL Server 2000 and here is the main part of it:

 SELECT id, rank, firstName, lastName, service, status, createdTime
 FROM   accessRequest
 WHERE  lastName LIKE @tLastName
     AND    firstName LIKE @tFirstName

And the C# code behind from the class file:

SqlDataReader spResults;


spResults = command.ExecuteReader();

while( spResults.Read() )


AccessRequestSearch request = new AccessRequestSearch( (int)spResults.GetInt32( 0 ), spResults.GetString( 2 ), spResults.GetString( 3 ), spResults.GetString( 1 ), spResults.GetString( 4 ), spResults.GetString( 5 ), Convert.ToDateTime(spResults.GetString( 6 )));

searchResults.Add( request ); // Add to Array List



The part in red is where I think it's happening because that is what I just added to the request.  createdTime in the table is set as DateTime.

Can anyone see what I am missing here?

More info is available if needed.

Specified Cast Is Not Valid
im doing a sum on a table and it either returns a number in decimal format or 'null' .  The problem is when it returns null i want it to just make the text say '0.00'.  So i did a test on the object that if it returns NULL just print  '0.00' but if it is not null it tells me that there is a number there and i want to store that as a decimal and print it out.  But i get an error for a type cast when im not it should not even be going to that part of the code. In the code below the first executescaler will return null so it should just go straight to the else.  But it gives me the type cast error in the if that shouldnt be seen.  The error and code are below. //Borrower NSF FEES
cmd.CommandText = "select sum(itemamount) from postmtdtls where loanid='" + LoanID + "' and Transactioncode = '310'";
object temp = cmd.ExecuteScalar();
if (temp != null)
decimal B_NSFFees = ((decimal)cmd.ExecuteScalar());
borrowerPayoff_NSFFees.Text = String.Format("{0:#,#.##}", B_NSFFees).ToString(); //Borrower NSF FEES

SSRS2000 - Specifies Cast Not Valid

I get the above error everytime I try to export to Excel; exporting to PDF works fine.

The only way I can get rid of the error is by deleting all the data from within the report (not ideal!). Anyone got any ideas on what could be causing this?

Many thanks,

Got 'Specified Cast Is Not Valid' Opening Mining Model Viewer
Hi all

I have a problem I created mining model with Microsoft Sequence Clustering algorithm, when I tried to open it in viewer, I got an error 'Specified cast is not valid'.
After looking in SQL profiler I see, that viewer execute MDX query to get node attributes of modelELECT FLATTENED TOP 1 (SELECT [ATTRIBUTE_NAME] FROM [NODE_DISTRIBUTION] WHERE VALUETYPE = 1) FROM [Dating Usepath].CONTENT WHERE NODE_TYPE = '13' - this query returns empty result set.

I modified it and got the following:

Op To Immo 5
Rating Range 5
Action 5
Age Int 5
Op To Immo 5
Rating Range 5
Action 5
Age Int 5
Op To Immo 5
Rating Range 5

It's only the bottom of resut set, but it shows that the names of attributtes actually empty.

What I did wrong, and what I possible change in the model to view Cluster diagram correctly.

P.S. When I created model on the same data with Microsoft Clustering algorithm everything is ok.

Cast From String &"&" To Type 'Date' Is Not Valid
Hello, I am using an SQLDataReader called DrCoInfo to check if any matching records exist in a table.

Line 120:While DrCoInfo.Read()
Line 121: If DrCoInfo("DateOfMan") <> "" Then
Line 122: BValid = True
Line 123: End If

However, it fails to work with the message :System.InvalidCastException: Cast from string "" to type 'Date' is not valid.

Any suggestions? Thanks.

Can someone please explain what I am missing here....
MySQL = "SELECT * FROM ClinicalSpecimen WHERE SpecimenID = CAST(('" & AccessionPresent & "') AS VARCHAR(50))"
*"AccessionPresent" is the value of the text field retrieved from the form.

CAST Command
I am using MS-Access as a front end for my MS-SQL DB. I have a sql view thatuses the following:SELECT TOP 100 PERCENT RECID, PATNUMBER AS [PAT #], SVCCODE AS [ServiceCode], QTY, PROF_CHRGS AS [Pro Fee's'], AMOUNT,BILLDATE AS [Bill Date], CHKAMT AS [Check Amt], PSDATEAS [Service Date], POSTDATE AS [Post Date], TRNSCODE AS [T Code],TRLR AS [T Code Desc], SUBSTRING(CAST(SVCCODE ASvarchar), 1, 4) AS [Dept #]FROM dbo.PAT_TransactionsORDER BY PATNUMBER, SVCCODEMy problem is the cast command. Will this sql view works and cast theSVCCODE field into a varchar, I need to cast the reseult of this,SUBSTRING(CAST(SVCCODE AS varchar), 1, 4) AS [Dept #], back in to a decimalformat. I am dropping this view onto a form and need to link to a field onthe form that is in decimal format.The only way I could get this to work was to create another view, based onthe one above, and cast the [Dept #] field back into the decimal format. Isthere any better way to do this? Can I nest the Cast command?Hope this makes sense.Thanks in advance.Mikem charney at dunlap hospital dot org

A return value of1 guarantees that expression can be converted to one of these numeric types."An application that has worked for years, failed when a field of type CHAR(3)(that should be an area code) contained a period only.

Check If Cast Is Possible
I use to import data from DBF Clipper databases into SQL Server. When a table is just imported its date fields have string format. I need to copy their data to tables of database where they ahve to be converted into date. Direct operator INSERT doesn't convert properly (I've not successed in changing default date format so it'll be covertable) but using CAST I can get result of strings like 13.05.1970 0:00:00 as datetime type. But not all records can be coverted this way. For ones can't be converted I've solved to make NULL fields there. But I don't know how to make CAST operation return NULL when convertion isn't possible. The query
INSERT INTO people_temp
(reg_num, surname, stname, patronymic, foreing, gender, birthdate, fam_pos, dwell_type, children, nation, par_not, region, stud_fml, parn_fml,
com_prob, sp_prob, sn_passport, nn_passport, dv_passport, wg_passport)

CAST(PSPR_temp.DATA_BORN AS smalldatetime), PSPR_temp.SEM_POL, PSPR_temp.XAR_JT, PSPR_temp.CHILDREN,

PSPR_temp.SV_ROD1 + PSPR_temp.SV_ROD2 AS Expr1, PSPR_temp.REGION, PSPR_temp.STUD_FML,

gets an error 'The conversion of char data type to smalldatetime data type resulted in an out-of-range smalldatetime value'. Tell me please how can make type casting return NULL if convertion isn't possible.

Cast Formula
I have a quick question. created a report with this formula below. It works when I put a date range from 1-1-2007 to 2-1-2007, but when I put in a date range of 03-01-2008 through 03-31-2008. i get an error message of arithmetic overflow error converting numeric to data type numberic.

So instead of haveing the formula below be (4,2) I put it as (5,2) and now it work. Why is that?

CAST(clm_sppo / clm_tchg * 100 AS decimal(4, 2)) AS PercentSavings

CAST Problem
I have a problem with CASTING

I have a CASE stmt, i check a var that is an int in the db, but based on values i wanna display strings.


CASE var1
WHEN var1 = 51 THEN 'Level 1'
WHEN var1 = 52 THEN 'Level 2'
ELSE var1
END as x

This gives me Conversion failed when converting the varchar value 'Level 1' to data type int.

Fair enough
but when i try to cast it it still gives me the same error ?

CASE CAST(var1 as varchar(10))
WHEN var1 = 51 THEN 'Level 1'
WHEN var1 = 52 THEN 'Level 2'
ELSE var1
END as x

Error When Using Cast
Hi, I'm very new to SQL. Trying to sum two fields, but I have to change the datatype first. Here's the code and the error message I receive. Any help would be appreciated.


Incorrect syntax near the keyword 'WHERE'.

Hello Everyone,

How do I change the format of the Date:

2006-06-01 00:00:00.000

to this:


I believe this can be done with a Cast.

Am I correct?

Help In Cast Function!

I have a table with the following structure:
Table: Meeting
ID integer not null
Desc text null

Here Col 'Desc' is a text type stores description. I have used the following UPDATE query:
UPDATE Meeting SET Desc='New Updated text......' + ' ' + CAST(Desc as varchar) WHERE ID=100

1. Since i did'nt specify lenth for varchar it takes only 30 chars from existing value and added to the edited text.
2. If i give like this CAST(Desc as varchar(8000)); it might take only first 8000 chars; remaining would be truncated correct? I assume that will happen.
3. If i don't use CAST i get error msg: "Invalid operator for type.."
Is there any work around in this situation? or better way to do it.

Looking for your help.

Safe Way To Cast
I have a table that stores a value called "LocationNumber" as a varchar. I didn't create the database, I just use it. Anyway I usually sort the list by Casting the LocationNumber to an Integer. If I don't cast it, it trys to sort it lexiographically i.e. 0, 1, 21, 3, 345, 9 instead of 0, 1, 2, 3, 9, 21, 345.

It works 99.9% of the time, but the other 0.1% of the time it runs into some text that somehow made its way into the database field, and it causes an error.

Is there a way to safely cast a number in SQL? So that it just returns 0 when the value is not a number.

Cast Problems With CLR

i have looked at several guides, and have come up with some code, although for some reason i am unable to get it to work, and receive an error:

Msg 6260, Level 16, State 1, Line 1
An error occurred while getting new row from user defined Table Valued Function :
System.InvalidCastException: Unable to cast object of type 'System.String' to type 'System.Object[]'.
at UserDefinedFunctions.FillRow(Object obj, String& PID)

Below is my code:
using System;
using System.Data;
using System.Data.SqlClient;
using System.Data.SqlTypes;
using Microsoft.SqlServer.Server;

using System.Collections;

public partial class UserDefinedFunctions
const string SELECT =
@"SELECT pointData.PID
FROM pointData
INNER JOIN pointDevices ON pointData.PID = pointDevices.PID
WHERE pointDevices.UUID = @UUID AND

[SqlFunction(FillRowMethodName = "FillRow", DataAccess = DataAccessKind.Read, TableDefinition="PID nvarchar(50)")]
public static IEnumerable createJourney(SqlString UUID, DateTime DATE_START,DateTime DATE_STOP, SqlDouble JOURNEY_DELAY, SqlDouble JOURNEY_DISTANCE)
ArrayList RAW_PID_LIST = new ArrayList();

using (SqlConnection conn = new SqlConnection("context connection=true"))

SqlCommand command = new SqlCommand(SELECT,conn);


SqlDataReader reader = command.ExecuteReader();

using (reader)
while (reader.Read())

return RAW_PID_LIST;

private static void FillRow(Object obj, out string PID)
object[] row = (object[])obj;

PID = (string)row[0];

could someone give me a clue as to why i might be getting this error please.

thank you.

Cast Function
I'm trying to cast the variable Alumni and keep getting a "The type of the value being assigned to variable "User::
Alumni" differs from the current variable type"error. The resultset from Records is a varchar(max) and the variable Alumni is a string. I found a blog that says to cast the result column to a max size limit. I want to do it this way so I can put the result in the message of a send mail task.

Here is the blog.

SELECT Records as Alumni

this doesn't work or I dont' have the syntax right?
SELECT Records as CAST(Alumni as varchar(max))

Cast Error, Please Help!
I'm encountering a Cast error, and find I am very much out of my league... I'm using a Derived Column Transformation to convert a column that comes from an Excel spreadsheet from a non-standard date format to DT_Date, though I picked this format simply because it was the first date format I found in the pick list. When I upload the ETL into Management Studio and run it I get the following error:

The data that is being converted appears as one of two things. First it can appear as a string value with 0 characters (that does not appear a Null oddly). Second it will appear as a string value representing a date in the following format 01022008 7:38 which is a date in the following the format 2 Digit Month,2 Digit Day, 4 Digit Year, Space Time in Military Time.

The expression I'm using to convert the String data type to a Date is:

Code Block

LEN([Completed Date Time]) == 0 || ISNULL([Completed Date Time]) ? NULL(DT_DATE) : (DT_DATE)(SUBSTRING([Completed Date Time],1,2) + "/" + SUBSTRING([Completed Date Time],3,2) + "/" + SUBSTRING([Completed Date Time],5,10))

Convert AND Cast
We have a 3rd party application that connects to our SQL 2005 as a external database source.

Our external database has a 'datein' field that for some reason is stored as a varchar(50).

I can use cast to convert the field to datetime, but how would I then format to the yyyy-mm-dd format in the same select statement(using in view)?

I need to convert this field to a format of YYYY-MM-DD in order for the 3rd party application to search on it correctly.
Below is an example of the data --
FieldName = DateIn
DateType = Varchar(50)
Sep 12 2007 11:16AM
Oct 2 2007 12:24PM
Oct 31 2007 8:00PM

Instance Specified Not Valid

I'm trying to install MSDE SP3 which I downloaded from MS at
Following the instructions as best I can I unzipped the file into a Folder now called MSDE located on C: I then went to a command prompt and typed in the command given to start the install:

setup SAPWD=testsite SecurityMode=SQL

Hit enter and the installer started up and ran for a few secs and then came back with

The Instance named specified is invalid

There was no mention of including an instance name or the format for it.

Suggestions please?

Also, if I want to completly uninstall MSDE if I need to how would I do it?

Valid Backup To Use
I have a question regarding the backup to use in case of consistency errors.

I'm backing up my dbs daily and logs hourly with 'verify the integrity of the backup when completed' checked. Today I found out one of my tables has 1 page id error (dbcc checkdb message from yesterday), I'm wondering if I can use yesterday's full backup even if it's done after the dbcc, that way I don't have to apply a lot less log backups. In other words, does or does not the full backup inherit the corruption if it is done after consistency errors and the backup passes the integrity verification.
