SQL Ce 3.5 && DataSet -&&> String Length??
Oct 10, 2007
Hi!
I create a dataset from a sqlce 3.5 database (I drag-dropped the tables of the database on the DataSet).
And when I try to put a text with more than 4000 characters in the dataset, it throw me an exception ....
--> I tried to insert this text directly in sql ce and it works well! So I think that the DataSet has a limitation?? But the maxlength of the string coloumn of the dataset is set to 536870911
Do you have an idea about this problem?
thx for help and sorry for my bad english

I have a created a table and entered data into the table as follows:
CREATE TABLE t ( id INT , txtcol varchar(1000) )
INSERT INTO t ( id , txtcol ) VALUES ( 1 , 'ATXR_SOURCE_ID,CDDL_AG_PRICE,CDDL_ALLOW,CDDL_ALTDP_EXCD_ID,CDDL_CAP_IND,CDDL_CHG_AMT,CDDL_COINS_AMT,CDDL_CONSIDER_CHG,CDDL_COPAY_AMT,CDDL_DED_AC_NO,CDDL_DED_AMT,CDDL_DIS_PA_LIAB,CDDL_DISALL_AMT,CDDL_DISALL_EXCD,CDDL_DISC_AMT,CDDL_DP_PRICE,CDDL_FROM_DT,CDDL_PAID_AMT,CDDL_PF_PRICE,CDDL_PR_PYMT_AMT,CDDL_PRICE_IND,CDDL_REF_IND,CDDL_RISK_WH_AMT,CDDL_SB_PYMT_AMT,CDDL_SURF,CDDL_TOOTH_BEG,CDDL_TOOTH_END,CDDL_TOOTH_NO,CDDL_TOT_PA_LIAB,CDDL_UNITS,CDDL_UNITS_ALLOW,CGCG_ID,CGCG_RULE,DPCG_DP_ID_ALT,DPDP_ID,DPTC_CD,PDVC_LOBD_PTR,PSDC_ID,UTUT_CD' )
Now if i select data using the query below the txtcol field displays only 255 characters :
SELECT * FROM t

I have a few columns in table with default value defined as zero length string (''). I want to insert record from DetailsView which uses SqlDataSource as DataSource. In the ItemInserting event, if the data is not valid, I want to use zero length string for the column. But I always get Null instead of zero length string. The code in ItemInserting event looks like this:
If objddl.SelectedIndex > 0 Then e.Values("myFld") = objddl.SelectedItem.ValueElse e.Values("myFld") = ""End If
The line: e.Values("myFld") = "" put Null in the column.
How can I set a column as zero length string using the SqlDataSource?
Any help is appreciated.
Thanks.

Hi,
I am trying to use DTC to import about 500 records from an Excelsheet to an SQL database.
Some fields contain strings with a length of about 1700 characters.
When i'm trying to execute the DTC generated code it is giving an error and saying that the maximum string length of 255 has been reached. Althoug the column in the database is defined as nchar(1750).
Does anybody know an answer to this problem ?
Thanks in advance,
Goofy

SQL 2000.I need a query that will search a field in the table that is 14characters long and begins with a number.I have a client that was allowing people to store credit card numbers,plain text, in an application. I need to rip through the table andreplace every instance of credit card numbers with "x" and the last 4digits. I got the replace bit going, but I am stuck on how to searchfor a string in a field of a specific length.Any ideas?Thanks,--Mike

How to parse a string to equal length substrings in SQL
I am getting a long concatenated string from a query (CTVALUE1) and have to use the string in where clause by parsing every 6 characters..
CREATE TABLE [dbo].[PTEMP](
[ID] [char](10) NULL,
[name] [char](10) NULL,
[CTVALUE1] [char](80) NULL
)
INSERT INTO PTEMP
VALUES('11','ABC','0000010T00010L0001000T010C0001')
select * from ptemp
after parsing I have to use these values in a where clause like this
IN('000001','0T0001','0L0001','000T01','0C0001')
Now ,the values can change I mean the string may give 5 values(6 character) today and 10 tomorrow..So the parsing should be dynamic.

I have a sp which works fine from my local database.
I move the procedure to a different database and modify it to access my data via linked server and I get the following:
provider "SQLNCLI" for linked server "Production" returned message "String data, length mismatch".
Msg 7421, Level 16, State 2, Line 27
Cannot fetch the rowset from OLE DB provider "SQLNCLI" for linked server "Production". .
Now I've seen references to this error message for ODBC, but as I said above, the same SP works fine if it goes against local data views. I am working with rather long concatenated strings using nvarchar(max) as the data type.
I've tried cast() on just about everything to no avail.
Anyone have any other ideas?
Thanks!

I'm having a problem with the XML Source data flow component not transferring the length attributes from an XML Schema to the column attributes of the output table.
An example schema that I have is:
<?xml version='1.0' encoding='UTF-8'?><data xmlns:xsd='http://www.w3.org/2001/XMLSchema' xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'><xsd:schema> <xsd:simpleType name='NameType'> <xsd:restriction base='xsd:string'> <xsd:minLength value='0'/> <xsd:maxLength value='50'/> </xsd:restriction> </xsd:simpleType> <xsd:element name='Name' type='NameType' nillable='true'/> <xsd:simpleType name='FamilyType'> <xsd:restriction base='xsd:string'> <xsd:minLength value='0'/> <xsd:maxLength value='50'/> </xsd:restriction> </xsd:simpleType> <xsd:element name='Family' type='FamilyType' nillable='true'/> <xsd:element name='row'> <xsd:complexType> <xsd:sequence> <xsd:element ref='Name'/> <xsd:element ref='Family'/> </xsd:sequence> </xsd:complexType> </xsd:element> <xsd:element name='data'> <xsd:complexType> <xsd:sequence> <xsd:element ref='row' maxOccurs='unbounded'/> </xsd:sequence> </xsd:complexType> </xsd:element></xsd:schema> <!-- data follows --> <row><Name>Fred</Name><Family>Jones</Family></row></data>
When I reference file in the XML Source data control, it correctly infers that there are two columns, but the length of the strings in the columns are set as 255.
This behaviour appears to be at odds with the SSIS documentation (SQL Server Integration Services/Integration Services Object and Concepts/Data Flow Elements/Integration Services Sources/XML Source), which states (highlighting mine):
When the data is extracted from the XML data file, it is converted to an Integration Services data type. The XSD or inline schema may specify the data type for elements, but if it does not, the XML Source Editor dialog box assigns the Unicode string data type (DT_WSTR) to the column in the output that contains the element, and sets the column length to 255 characters. If the schema specifies the maximum length of an element, the length of output column is set to this value. If the maximum length is greater than the length supported by the Integration Services data type to which the element is converted, then the data is truncated to the maximum length of the data type. For example, if a string has a length of 5000, it is truncated to 4000 characters because the maximum length of the DT_WSTR data type is 4000 characters; likewise, byte data is truncated to 8000 characters, the maximum length of the DT_BYTES data type. If the schema specifies no maximum length, the default length of columns with either data type is set to 255. Data truncation in the XML source is handled the same way as truncation in other data flow components. For more information, see Handling Errors in Data.
Has anyone had any luck in getting string lengths automatically extracted from an XML document? If so, where I am going wrong?
Regards,
Michael

I'm running into this error message when passing in a few records in particular to a function, the only difference I could find is that these recods have about 60k characters on the field that I'm passing to a function.
is there a max lenght for passing to a function?
select function ( field) as results
It's been working fine until today and all of the related fields are declared as nvarchar(max)
Thank you.

I'm working in a ASP.NET 2.0 application with a SQL Server 2000 database on the back end. I have a strongly typed dataset in the application that calls a stored procedure for the select. I'm having trouble filling the dataset at runtime though.
I am trying to use a character string query because I setup different columns to be pulled from a table each time and in a different order so my T-SQL looks like this:
set @FullQuery = 'Select ' + @FieldsinOrder + ' from tblExample'exec (@FullQuery)
This works fine in query analyzer. The results return and display correctly. However, when I run the application, the dataset does not get filled. It is like the results do not output to the application.
If I change the query to be a normal select it works. For example:
select * from tblEmample
That works fine. What is it about a select query setup as a character string and then executed that ASP.NET doesn't like?

is there any way or a tool to identify if in procedure the Parameter length was declarated less than table Column length ..
I have a table
CREATE TABLE TEST001 (KeyName Varchar(100) ) a procedure
CREATE PROCEDURE SpFindNames ( @KeyName VARCHAR(40) )
AS
BEGIN
SELECT KeyName FROM TEST001
WHERE KeyName = @KeyName
END
KeyName = @KeyName
Here table Column with 100 char length "KeyName" was compared with SP parameter "@KeyName" with length 40 char ..
IS there any way to find out all such usage on the ALL Procedures in the Database ?

For those of you who would like to reference my exact issue, I'm dealing with the RSExecution SSIS package at the "Update Parameters" data flow task, at the Script Component.
The script tries to split parameter data into name and value. Unfortunately, I have several reports that are passing parameters that are very large. One example has over 65,000 characters all in the normal "¶mname=value&parm2=value..." format.
The code in the script works fine until it gets to one of these very large parameter sets. I have figured out what is causing the issue. Here's some code:
Dim paramBlob as Byte()
paramBlob = Row.BlobColumn.GetBlobData(0, Row.BlobColumn.Length)
The second parameter of the .GetBlobData function takes an INTEGER as its count! Therefore, no matter what kind of datatype I pass to the string that the script will later split, it will be limited to 32767 characters.
THIS IS A PROBLEM!!!
Does anyone know a workaround for this issue? I need all of the parameter data to be reported, and I would hate to have to skip over rows like this. Also, if I'm missing something, please fill me in!
Thanks for your help in advance,
LOSTlover

I am trying to narrow down this problem. Basically, I added 3 columns to my article table. It holds the article id, article text, author and so on. I tested my program before adding the additional field to the program. The program works fine and I can add an article, and edit the same article even though it skips over the 3 new fields in the database. It just puts nulls into those columns.So, now I have added one of the column names I added in the database to the code. I changed my businesslogic article.vb code and the addarticle.aspx, as well as the New article area in the addartivle.aspx.vb page. The form now has an additional textbox field for the ShortDesc which is a short description of the article. This is the problem now: The command parameters.length is 9 and there are 10 parameter values. Right in the middle of the 10 values is the #4 value which I inserted into the code. It says Nothing when I hover my mouse over the code after my program throws the exception in 17 below. Why is command parameters.length set to 9 instead of 10? Why isn't it reading the information for value 4 like all the other values and placing it's value there and calculating 10 instead of 9? Where are these set in the program? Sounds to me like they are hard coded in someplace and I need to change them to match everything else. 1 ' This method assigns an array of values to an array of SqlParameters.2 ' Parameters:3 ' -commandParameters - array of SqlParameters to be assigned values4 ' -array of objects holding the values to be assigned5 Private Overloads Shared Sub AssignParameterValues(ByVal commandParameters() As SqlParameter, ByVal parameterValues() As Object)6 7 Dim i As Integer8 Dim j As Integer9 10 If (commandParameters Is Nothing) AndAlso (parameterValues Is Nothing) Then11 ' Do nothing if we get no data12 Return13 End If14 15 ' We must have the same number of values as we pave parameters to put them in16 If commandParameters.Length <> parameterValues.Length Then17 Throw New ArgumentException("Parameter count does not match Parameter Value count.") 18 End If19 20 ' Value array21 j = commandParameters.Length - 122 For i = 0 To j23 ' If the current array value derives from IDbDataParameter, then assign its Value property24 If TypeOf parameterValues(i) Is IDbDataParameter Then25 Dim paramInstance As IDbDataParameter = CType(parameterValues(i), IDbDataParameter)26 If (paramInstance.Value Is Nothing) Then27 commandParameters(i).Value = DBNull.Value28 Else29 commandParameters(i).Value = paramInstance.Value30 End If31 ElseIf (parameterValues(i) Is Nothing) Then32 commandParameters(i).Value = DBNull.Value33 Else34 commandParameters(i).Value = parameterValues(i)35 End If36 Next37 End Sub ' AssignParameterValues38 39 40 41

I went to look at the connection string previously entered for a dataset created in a new report, and am not seeing anything intuitive for bringing up the associated datasource dialog box that was used to enter name, type and connection string. I'm also noticing nothing intuitive for deleting an existing dataset. How do you do these two very simple things in an existing project? I dont see the dataset in solution explorer, I see it only in the text box on the data tab and in a limited kind of way on the dataset view where the columns show and maint is allowed mostly on the columns only. I tried hilighting the dataset here and hitting the delete key to no avail.

I have a report with multiple datasets, the first of which pulls in data based on user entered parameters (sales date range and property use codes). Dataset1 pulls property id's and other sales data from a table (2014_COST) based on the user's parameters. I have set up another table (AUDITS) that I would like to use in dataset6. This table has 3 columns (Property ID's, Sales Price and Sales Date). I would like for dataset6 to pull the Property ID's that are NOT contained in the results from dataset1. In other words, I'd like the results of dataset6 to show me the property id's that are contained in the AUDITS table but which are not being pulled into dataset1. Both tables are in the same database.

I have a small number of rows in a dataset, Table 1. There is a CLOB on a large dataset, Table 2. They join on a PK. I would like to retrieve this CLOB and add it to the data flow for Table1. In short I want to emulate the following:
Table 1: Small table without CLOB, 10 rows.
Table 2: Large table with CLOB, 10,000,000 rows
select CLOB
from table2
where pk = (select pk from table1)
I want this to return the CLOBs for the small number of rows in Table 1. The PK is indexed obviously so it should be a fast look up.
Table 1 and Table 2 live on different Oracle databases. How do I perform this operation efficiently in SSIS? It seems the Lookup and Merge Join wont do this.

Hi,
I have a stored procedure attached below. It returns 2 rows in the SQL Management studio when I execute MyStorProc 0,28. But in my program which uses ADOHelper, it returns a dataset with tables.count=0.
if I comment out the line --If @Status = 0 then it returns the rows. Obviously it does not stop in
if @Status=0 even if I pass @status=0. What am I doing wrong?
Any help is appreciated.
ALTER PROCEDURE [dbo].[MyStorProc]

Hi,
I have two datasets in my report, D1 and D2.
D1 is a list of classes with classid and title
D2 is a list of data. each row in D2 has a classid. D2 may or may not have all the classids in D1. all classids in D2 must be in D1.
I want to show fields in D2 and group the data with classids in D1 and show every group as a seperate table. If no data in D2 is available for a classid, It shows a empty table.
Is there any way to do this in RS2005?

Nothing))
Released_DT = a date - 09/03/2015 or 09/02/2015
Date2 = returns another date value in this case 09/03/2015
What I'm trying to do is: count distinct number of people (Fields!Name.Value) if the Relased_DT = Date2.My IIF statement is returning a zero value.

Hi experts,
I'm not sure my design is normal or not. Please give me some advice.
I've a dataset and query by a field name 'companyid'.
select * from companyid where companyid = @icompany which @icompany is a input field.
if user select all, i'll send 0 to @icompany then I need to select all records.
question 1. How can I get all records? (i think about this query select * from companyid <> 0)
if user select for example companyid = 1, i'll send 1 to @icompany and the query work fine.
question 2. How can I change the query to adopt this 2 condition?
Thanks a lot,
Jeff
