I've a MATLAB script which calls the update function to update a SQL Server database. But when i try to update a float data with a NaN value, i get the following error message:
Error using database.jdbc.connection/update
Unable to complete update operation. The incoming tabular data stream (TDS) remote procedure call (RPC) protocol stream is incorrect. Parameter 6 (""): the supplied value is not a valid instance of data type float. Check the source data for invalid values. An example of an invalid value is data of numeric type with scale greater than precision.
Note that the related float data can be null.

In SQL server to get value from field ,I need to use convert(varchar,column)
Data type is percentage float.
Value is like -0.07
Issue in QueryDsl
. I am not able to find similar way to convert data to string.
If I use .stringvalue method then its not giving same value and instead getting 0
So is there any way to convert value in QuerDsl?
I am trying to pull some Active warranty data using the following code
The data that i am pulling to understand the failure rate
In order to avoid null i am using ISNUll
,isnull(cast(count(a.[SVC_DSPCH_ID])as varchar(10)),0) as 'DSPCH_QTY'
,isnull(cast(sum(a.[REPEAT_DSPCH_DEFECT_FLG])as varchar(10)),0) as 'RPT_QTY'
,isnull(cast(sum(a.[RDR_28])as varchar(10)),0)as 'RPT28_QTY'
,isnull(cast(Sum(a.[REPEAT_DSPCH_QUALIFY_FLG])as varchar(10)),0) as 'Qualify_QTY'
but i am getting an error Error converting data type varchar to float.
Can any one help me with the same.
I'm developing app in .NET Core 3.1 with Visual Studio 2019 and everything works fine on my local machine with Windows 10 Pro. But after deploy to Azure this problem occurs:
The incoming tabular data stream (TDS) remote procedure call (RPC) protocol stream is incorrect. Parameter 9 ("#p8"): The supplied value is not a valid instance of data type geography. Check the source data for invalid values. An example of an invalid value is data of numeric type with scale greater than precision
This error occurs when adding Post to database. Post has property of type NetTopologySuite.Geometries.Point and is set like that:
location = new Point(longitude, latitude) { SRID = 4326 }; where longitude and latitude are double.
When I set location to null then error doesn't appear.
I tried to use less precision, like 2 digits before dot and 6 digits after - this still causes error.
I use Entity Framework Core. It generated db column as Location (geography, null).
Edit:
I'm converting lat and lon strings to double like that: Convert.ToDouble(longitude.Replace(".", ",")). I removed .Replace(".", ",") and now it works on Azure, but the same error appear on local env.
I have spatial with id 4326 on both dbs.
Finally i changed:
Convert.ToDouble(longitude.Replace(".", ","))
to
Convert.ToDouble(longitude, CultureInfo.InvariantCulture)
and now it works on both - local and Azure.
Solution inspired by this: string to double issue, dot is removed
I'm getting the following error when I run my package:
[Data Conversion [2]] Error: Data conversion failed while converting column "FieldName" (373) to column "Copy of FieldName" (110).
The conversion returned status value 2 and status text "The value could not be converted because of a potential loss of data.".
However, I don't understand why. I have double checked the inputs and outputs to validate that they make sense and are what I expect. I've also checked all the raw data in the column in my excel file.
My package setup:
Excel Datasource feeding Data Conversion then Derived Column and finally output to Ole DB Destination (sql)
What I've done:
I opened the advanced editor on the data conversion. I confirmed that the incoming data type is DT_STR which can be expected since the source datatype wasn't correctly identified. It is actually a date in my excel file. I confirmed that the data conversion output column is database timestamp [DT_DBTIMESTAMP] as I have set it to be. My destination table has a DateTime datatype for FieldName.
What am I missing?
I think this is a date format issue, check that column does not contains empty strings or NULL values.
Also check that values are similar to yyyy-MM-dd HH:mm:ss date format.
To read more about SSIS data types check the following article:
Integration Services Data Types
Also when converting string values to datetime, if values are well formated, just map the source column to the destination without Data conversion Transformation and they will be implicitly converted
insert into mytable values(1,'06-06-2012');
why do we include date within single quotes here?!! However, we do not do the same while passing the value through parameterized query?!!
With literals, the SQL Server database engine parses the value into native format during query execution. The datetime value is parsed into an 8-byte native binary representation.
Parameter values are passed to SQL Server in native binary format so enclosurse are not used. The client API converts the parameter value according to the declared parameter data type and passes the binary value to SQL Server using a TDS protocol remote procedure call. SQL Server doesn't need to parse the value at all, although conversion might still be needed if the parameter data type doesn't match the data type needed in the query.
For example, if you pass a string parameter value of '06-12-2014' for a table data type of datetime, SQL Server will convert the parameter string value to datetime according to the session DATEFORMAT setting (could be interpreted as '2014-06-12' or '2014-12-06. Passing a native datetime parameter avoids the ambiguous date format because the task of converting the value to the native binary value was already done on the client.
