One Or More Columns Do Not Have Supported Data Types, Or Their Data Types Do Not Match.
Oct 20, 2007
Hi,
I´m exporting an ms-excel file, then I use a lookup transformation to get a field from a SQL Server 2005 table. The Lookup transformation editor, after selecting the table, shows a warning that says:
at least one mapping between a column from available input columns ans a column from available lookup columns must be defined on the columns page.
So I try to make a relationship in the Lookup transformation editor's column tab where I find the Available input columns and the available lookup columns but I get the following error:
The following columns cannot be mapped:
[Department, DEP_CLEGALCODE]
One or more columns do not have supported data types, or their data types do not match.
The field in SLQ Server is varchar(10) and the input field is a derived column transformation; I have tried different Data Types but I always have the same error.
The DataFlow is: ExcelSource --> Derived Column --> Lookup --> Flat file destination
I have a flatfile source with qty,title and author..i add a lookup and in that i establish relation between title and titel of pubs database..but i am getting an error.. one or more columns do not hav supported data types,or their datatypes do not match..i checked both hav dt_str,and in database pubs title is varchr..so why this eror?
I'm trying to import data from an Informix Database to my SQL Server 2005 database with the import/export wizard. I have an ODBC-connection that works, Access fetches data with no errors. From the wizard I can only choose to use the IBM Informix OLE DB Provider as datasource. As fare as I know the OLE DB Provider is using settings from the ODBC-driver?
In SQL Server 2000 there is a posibillity to choose Other(ODBC provider) as datasource which works against this database. Any ideas how i can use an ODBC-datasource?
If I try to use the IBM Informix OLE DB Provider I get an error message after the first step of the wizard:
Cannot get the supported data types from the database connection "Provider=Ifxoledbc;Password=;Persist Security Info=True;User ID=uid;Data Source=db@server".
We have a table in DB2, which has a column1 (Data type: - decimal (10, 0)) and column2 (Data type: - varchar (70)), I need to concatenate these two columns into one while displaying output
Procedure I followed:--
Tried to convert column1 to varchar using cast function so that I could concatenate both columns. However I ended up in getting the following error message
As part of an ETL conversion I have dataflow task created that copies data from one table to another, we use it as a way to rename fields and change data types. What is strange is that the OLE DB SQL destination has not issue if I copy data from an int to smallint and in another case from an int to a numeric field and it runs fine. So I decided to test using a SQL Server Destination as I heard it may be faste that using OLE Db.
No I am getting the following error
Error: 0xC02020F5 at Insert into TRANSACTION, SQL Server Destination [32]: The column "ID" can't be inserted because the conversion between types DT_I4 and DT_NUMERIC is not supported. Error: 0xC02020F5 at Insert into TRANSACTION, SQL Server Destination [32]: The column "ID1" can't be inserted because the conversion between types DT_I4 and DT_I2 is not supported.
I do understand the error but not why it runs fine using the OLE DB but when running it through SQL Server Destination I get this error.
I'm not a DBA but I'm doing what is turning into way too much work... Yes I understand you want to do memory intensive data conversions and SQL server is not tolerant, etc....
But, I have to get my data from a flat source into a table in SQL server. I know DT_I1 is a 1 byte signed integer, I see System.Byte, but surprise, NONE of the TYPES in defining my table in SQL Server Management Studio correspond to any type that it accepts.
What am I doing wrong?
I have a table in SQL Server. I know DT_I8 is Bigint, I know DT_I4 is Int. Bigint and Int, for example, are two types I have access to when I'm building my table. But what on EARTH is DT_I1? It is NOT a TYPE that I can dropdown and choose.
My SSIS package has a Flat File Source that points to my comma delimeted file on my PC, it has a Data Conversion element that seems to do nothing..., and of course a SQL Server Destination which is my table.
I would rather just have the SSIS package create the right table on the fly.
DTS was much easier, I know, not as efficient for 1,000,000 rows, but guess what, there are still small to medium size businesses that don't need that efficiency to get in 1MM rows +, we just need to get our jobs done.
Help...
P.S. I'm creating the SSIS in MS Visual Studio Professional.
Error at Data Flow Task [SQL Server Destination [14]]: The column "Opened On" can't be inserted because the conversion between types DT_DATE and DT_DBTIMESTAMP is not supported.
Error at Data Flow Task [DTS.Pipeline]: "component "SQL Server Destination" (14)" failed validation and returned validation status "VS_ISBROKEN".
Error at Data Flow Task [DTS.Pipeline]: One or more component failed validation.
Error at Data Flow Task: There were errors during task validation.
I tried using Data Conversion and Derived column, still this error prevails. Any help ????
and coupled it to a Flat File Source. The Flat File Source suggested that the type was DT-I1.
Next I created a €œSQL Server Destination task and connected the output of the Flat File to the Sql Destination. In the Destination editor I created a table, whose one column was declared to be a sql smallint.
Here€™s the problem: the Sql Server Destination now displays a red circle with a white €œx€?. The tooltip says that: €œThe column €œColumn 0€? can€™t be inserted because the conversion between types DT_I1 and DT_I2 is not supported€?
Can anyone explain why the conversion is not supported?
TIA,
Barkingdog
P.S. It's not kidding! When I changed the Flat File Source type to DT-I2 everything worked fine.
I created a function to call my CLR Object (See below). I keep getting the following error (failed because T-SQL and CLR types for return value do not match) no matter what data type I try in the function. The Dll is passing back a string data type. What am I doing wrong?
CREATE FUNCTION [dbo].[fnGenerateTheoreticalValue]

@LGD float,
@OID int,

I am trying to find a reference for a client that lists the fields available to be substituted into a data driven subscription from the query, along with the expected data types.  For example, the field on whether or not to include a link to the report seems to be expecting a bit data type.I have searched and can't seem to find anything.  I guess I could walk through the interface and try different data types, but if  a list exists, that would be better.Â
I am trying to create a CLR function to call a webservice, the CLR function return data type is double, whether I try to create this as a table valued funcion or a scalar to return a distance travelled value I am receiving the error below.
I've tried changing data types around in the CLR side and the SQL side but keep receiving the same error message:
[Microsoft.SqlServer.Server.SqlFunction(Name = "DistanceCalc")] public static Double DistanceCalc(Double SrcLat, Double SrcLong, Double DestLat, Double DestLong) { MileageWS ws = new MileageWS();
[Code] ....
Error received when try to Create function ... 1, Level 16, State 2, Procedure pcMiler, Line 6 CREATE FUNCTION for "pcMiler" failed because T-SQL and CLR types for return value do not match.
While run time these values are lets suppose @SSN = '999-000-000' & @State='ABC'
Now the Result is displayed with the state data Like 'AB' only.
Output: 1 999-000-000 AB
instead it should give system generated error.
Here I have 2 Questions: 1. Why it is taking 1st 2 Charecters? 2. Why it does not have any system generated for length?
I can do validation with Length function for these 2 variables however if have 100 variables then it should not feasible case. So, what is the reason behind?Â
I'm in the process of converting a rather huge VSAM database into a set of SQL tables. I am using the same data names from the mainframe (like XDB-NAME to RDB-NAME). I load the files using Import Export Data and it makes the tables with such column names as col001, col002, col003, etc... and always sets the data types to varchr(255). And I have to cut and paste the data names from the manframe side to the server side (and the data types to.) So, is there an easier way to do this? Or am I doomed to cut-n-paste my days away... Thanks for any help.
I've been writing this stuff for a while, and can't seem to come to the conclusion of how I should be retrieving data and assigning this data to variables.
Since i'm using SQL Server, I'm convinced that I should be using the datareaders GetSqlDouble (or whatever) function, but this would mean i need my local variables to be one of the SQL types. The problem with that is, that there will have to be lots of conversions done by me to be able to use a SQL type in my application.
For instance, I have a class where i'm retrieving dates. In order to retrieve them correctly (Null values included), I need to retrieve them with GetSqlDateTime(), then when it comes time to display the date in a table, i must first check for nulls, then convert to a string. This seems to be very cumbersome. Would I be better off just using GetDateTime(), and the .ToString method, and ignoring Sql Types all together?
so, basically, how are you guys using your sql server data? with the supplied sql types, and doing all of the post-processing work manually? I feel like i'm having trouble conveying my issue...hopefully someone knows what i mean....i'd just like some direction to save trouble in the long run, since i feel like there's got to be a better way...
Is it possible to easily copy data from one table to another if the data types don't match. I know you can do a INSERT INTO table1(col1,col2) SELECT (col2,col7) FROM table2 if the data types match but is there a way to do this if they don't. I'm not trying to copy date times into bit fields or anything. I just have an old table that I built when I really didn't know what I was doing now I at leastthink I have a better understanding of what data types to use, so I was wanting to move the data in the orignal table to my new one. Most of the fields in the olddatabase are text datatypes and the new database is nvarchar(50) data types. Thanks for any suggestions.
I have a really dumb question regarding SQL data types. I have a couple columns in a table that are specified as MONEY. These columns are being read from my web app and displayed on the website for reference when filling in other information.
My problem is that when it is displayed on the website it give four decimal places instead of two. For example I want it to report $33,000.29 but what is actually displayed is $33,000.2965.
How can I set up either SQL or my web app so that it only displays the two decimal places? I've looked into changing the datatype already but SMALLMONEY and MONEY have the same type of decimal values.
I am looking for a chart of SQL Server data types and information about them, such as usage, constraints, etc. Could anyone point me in the right direction?
I'm just getting used to using SQL 7 Database and am looking for some recommendations on what DATA TYPES to use when designing tables.
The site I am working on now uses cold fusion to enter, update, and insert mainly text and articles. Now the problem with the articles is that some of them are pretty big. And when inserting or updating them, if they go over the limit of characters I get an error.
I know in access I used to use the data type "MEMO" and be able to put a large piece of info in that field.
What's the equivalent for SQL server databe?
What are the most used/common or recommended data types that should be used when putting tables together?
hi, i'm trying to build an online forum using sql server 2000 and coldfusion mx.
could anybody help me as to what datatypes i should use for my database fields?
i'll be using 2 simple tables to start with, ie TOPICS and POSTS. each will contain fairly basic information such as name of poster, time, data, title, message etc.
any help would be greatly appreciated. thanx, zaffi.
Which data type do I need to assign to my field to let users enter characters such as +=-_| etc....pretty much every single character from a standard keyboard....
I am pretty new with SQL and was dabbling in a test database that is linked with a software application.
I made a change to a table - Lets call this (Table1). Table1 has a multiple columns.
Column1 is defined as numeric(9) Column2 is defined as varchar(20)
In this case, I wanted to make all values in Column2 = Column1 that did not have a value defined so I ran the following query:
update Table1 set Column2 = Column1 where Column2 = ''
This took effect but the particular software application doesn't recognize these values because they are the wrong data type.
How can I convert all data in a column to varchar(20) if it is another data type (i.e. in this case numeric(9))?
I've tried in Enterprise manager to redesign the table and adjusted the length to 21 and then back and saved it but this did not work. I was looking at Convert and Cast functions but don't know how to write one to accomplish what I need to do here.
Half of the data in Column2 is varchar(20) and half is numeric(9). I want all to be varchar(20).
Im comparing values. if i add the values which is numeric or monetary in the column and if it is greater than zero it will insert to a table, but the datatype of my column([Day 30 AMT] etc. is char. i want to implement like these like these because it cant return a result if i query..
I want to store a decimal value which I get from an execute sql task into a package variable. Which data type should I specify when creating the package variable?
I have successfully made a couple of SSIS packages to read data from a legacy AS400 to SQL Server 2005. These are working fine. I am now working on one that is trying to pull some financial data and I keep getting the following error for the decimal columns:
"The component ciew is unavailable. Make sure the component view has been created. The input column "input column AMT1 (2870) cannot be mapped to "external metadata column AMT1(2852) because they have different data types."
Now I made sure that the data sitting on the AS400 is of type decimal and the SQL server column is the same. What else do I need to look for?
Hello, I am following this article about building an ASP.Net application which uses SQL Express 2005. The document calls for building a couple of tables. One column is identified with data type of "Byte" which are is available for selection within the Visual Studio 2005 interface. The following values show in the drop down of data type in VS2005:
Bigint Binary(5) Bit Char(10) DateTime Decimal (18,0) Float Image Int Money NChar(10) NText Numeric(18,0) Nvarchar(50) Nvarchar(max) Real SmallDateTime SmallInt SmallMoney Sql_Variant Text Timestamp TinyInt UniqueIdentifier Varbinary(50) VarBinary(max) varchar(10) Varchar(max) XML
I choose Char with a size of 1. Would this be correct, or am I missing something?
Is there some type of resource that tells you what all the Data types are and what they are used for. For example, whats the diffrence between Nvarchar and Char? Things like that. Thanks!
Having a slight problem. For whatever reason I had a column setup for nvchar but the only data i have in there is dates (MM/DD/YY) and a whole bunch of NULLs. I wanted to change the datatype to datetime but it gave me an error. I thought it was due to all the NULLs, so I removed all the nulls. It still doesn't work. I get the error : Conversion failed when converting datetime from character string. I don't belive its because I have the data in mm/dd/yy format. I created another table and populated it with mm/dd/yy data as nvchar (50) and then converted to datetime and it worked fine. any ideas?
