How To Store Null For An Decimal Type To Sql Server?
Apr 3, 2008
Hi Experts,
I have an urgent needs.
I want to store null for decimal type to sql server. But I do not know how to do that. I get data from user input. If the user did not enter anything in the textbox, then I want to store null to sql server. I list a piece od code below. I got error in the last line fItemObject.ChargeAmount = null;.
if (!String.IsNullOrEmpty(txtDescription.Text))
myObject.LongDesc = txtLongDesc.Text;
else
myObject.LongDesc = null;
if (!String.IsNullOrEmpty(txtAmount.Text))
myObject.Amount = Convert.ToDecimal(txtChargeAmount.Text);
else
myObject.ChargeAmount = null;
I am working with a legacy SQL server database from SQL Server 2000. I noticed that in some places that they use decimal data types, that I would normally think they should be using integer data types. Why is this does anyone know?
Example: AutomobileTypeId (PK, decimal(10,0), not null)
I am creating a table on SQL Server. One of the columns in this new table contains whole integer as wells as decimal values (i.e. 4500 0.9876). I currently have this column defined as Decimal(12,4). This adds 4 digits after the decimal point to the whole integers. Is there a data type that will have the decimal point only for decimal values and no decimal point for the whole integers?
I would like to cast (convert) data type decimal(24,4) to decimal(21,4). I could not do this using standard casting function CAST(@variable as decimal(21,4)) or CONVERT(decimal(21,4),@variable) because of the following error: "Arithmetic overflow error converting numeric to data type numeric." Is that because of possible loss of the value?
Happy Friday! A while since I have posted a question, and this one is probably real easy. I am trying to store numeric values from a php form in MSSQL 2000 database. However, the columns are set to float and if the value is 1.00, when entered into the table it is saved as 1
If I change the column type to money, the query fails, with an error message of conversion of datatype varchar to datatype money statement terminated.
anybody know what I need to do? do I need to do something in my query to specify that this is NOT varchar data?
The table in SQL has column Availability Decimal (8,8)
Code in c# using sqlbulkcopy trying to insert values like 0.0000, 0.9999, 29.999 into the field Availability we tried the datatype float , but it is converting values to scientific expressions€¦(eg: 8E-05) and the values displayed in reports are scientifc expressions which is not expected we need to store values as is

security ids seem to be made up of at least 3 32 bit unsigned numbers and a few smaller numbers. We believe their lengths vary. We dont mind dropping the "S" from the front. What data type do you recommend be used for their storage? We expect only limited joins and user visibility on this column. We may wish to create an index on this column. We think varchar and varbinary are the two major choices.
Hello, I am wondering how it is going to work using SQL Server configuration type to store connection string in the SQL Server table. How does SSIS know what database to connect to if its connection string is store in the database? Thanks
I'm using the XML Source to process a hierarchical set of XML. As such, the XML Source creates keys to maintain the hierarchy. This is very convenient, and keeps me from having to invent my own keys.
The problem is that the datatype of these keys defaults to DT_UI8. Which SQL Server 2005 datatype should I use to store these values in my staging tables? BIGINT corresponds to DT_I8, which can't accept DT_UI8 values.
Should data type money allow nulls? Are there valid arguments both pro and con?
Yes, there is the age-old question regarding how one might interpret a NULL found in any column - does it mean the amount is not known or that the amount is zero (in the case of a numeric type)? You get the drift...
Other than that, though - are there any practical considerations an old data hound ought to be aware of?
Hello, I heve the code below. double prix =TextBox1.Text; And I have SQL SERVER table Products in witch I have a column prix ( Decimal(16,4) ) But if I insert prix on my table products on the field prix. prix does not take the correct value. For example if TextBox1.Text=19,6 , the value inserted on the field prix in the table will be 20. Why ? How can we insert the correct value ?
I have decimal(6,2) defined in a column. If I insert 90.6, it will display 90.60 , 0 becomes .00 . Is there a way or configuration change so the 0's will on the last will not be showing. And the 0 will display as 0 not .00?

I am using the statement below to calculate the average scores of the columns. When the result set is returned I would like to have a scale of 2. I am currently returning a scale of 6. What could I do to fix this?
Thanks for you help, John
SELECT ((CONVERT(decimal(4,2),c2_3) + CONVERT(decimal(4,2),c2_15) + CONVERT(decimal(4,2),c2_16) + CONVERT(decimal(4,2),c2_17)) / 4 * 100) AS Score_A FROM dataquestionnaire WHERE confirmation = '10/1/2001-999-1'
This one cost me a solid half hour yesterday. I'm wondering why onearth the default precision for a decimal type is 18,0. Maybe I'mmistaken. A decimal datatype sort of implies that you'd want somethingafter the decimal!Question is, can I set this database-wide? Like all new decimaldatatypes have a precision of 12,6 or something like that? I haven'tseen anything about this in the googling I have done...
I need to store 256 bit hash (SHA-2 alogrithmn) in one of the table'sprimary key. I would prefer to use numeric data type rather varcharetc.* Decimal datatype range is -10^38 +1 to 10^38 -1. I can split my 256bit hash into two decimal(38, 0) type columns as composite key* I can store the hash as varbinary. I never used it and don't havemuch understanding in terms of query writing complexities and dealingit through ADO (data type etc.)It would be heavy OLTP type of systems with hash based primary keyused in joins for data retrieval as well.Please provide your expert comments on this.RegardsAnil
This problem is strictly an SQL problem, and I am about to lose my mind over it. I have a table named Inventory that has a column named PartialQty which is of type DECIMAL(11,4). I have shortened my query for simplicity, but here it is. DECLARE @pqty1 DECIMAL(11,4) SELECT @pqty1 = PartialQty FROM Inventory WHERE InventoryID = @invIDPRINT @pqty1 UPDATE Inventory SET PartialQty = 6.5513 WHERE InventoryID = @invID SELECT @pqty1 = PartialQty FROM Inventory WHERE InventoryID = @invIDPRINT @pqty1 Before this query is ran, the value in PartialQty is 1.2345. If I run this 2 times in a row, this is the output I get: RUN 1: 1.2345 (1 row(s) affected) (1 row(s) affected) (1 row(s) affected) (1 row(s) affected) 6.0000
RUN 2: 6.0000 (1 row(s) affected) 6.5513
I don't understand 2 things. One is why the first run displays (1 row(s) affected) 4 times even though there is only one record with that InventoryID. And the other thing I don't understand is why the first time I run it, it loses all of the values after the decimal point. Please help, Scott
I have just loaded my db table from an excel file using the import wizard. Prior to the import, I set my data types and in the field that I need a number with 1 decimal place I chose a decimal data type.
Made since to me
However, now my numbers do not have the decimals. Please help.
I have a table in SQL 2005 with a field that has a value of type 'money'. When values are added, the field has 4 decimal places. Is there a way that I can make it only have 2 decimal places right away? Thanks!!!
I'm trying to update a decimal field with a single decimal number (1.8) the problem i'm having, is that it's rounding the number up (2). I would've thought that a decimal datatype would keep the decimal places correct?
This is quite annoying.. I've been searching around the web for an answer.. To no avail (I'm probably asking the wrong question)
Can someone please point me in the right direction?
I am trying to have an Excecute SQL Task return a single row result set executed on SQL Server 2005.
The query in the Execute SQL Task is: select 735.234, 2454.123
I get a conversion error when trying to assign to SSIS variables of type Double. I have nothing configured in the "Parameter Mapping" tab. I have the two SSIS Double variables mapped to the Tesult Name 0 and 1 in the "Result Set" tab
I don't want to use a for loop enumerator since there is a single row returned.
I simply want to assign these two values to SSIS Double variables (double is the closest match)
I can't even hack this by converting the decimals as string and then using DirectCast to convert them to Double.
1. Have a query that fetches a real value (e.g. 4.3345643)
Let say the field is called TheReal.
How can I format the value in the select statement so I get a thousand separator(s) and two decimals in the resultset.
2. In the same query I have a left join as well. Table 2 retur (sometimes) <NULL>. Is it possible to force this <NULL> value to be a fixed string value instead in the select statement.
Hi.. I have a column in the data base with the type Float, I want to limit the number of digits after decimal point to 2 when I display the value in ASP.NET but I don't know how!? the number that appear after calculation llike "93.333333" I use decimal(2,2) as data type but an error accour and this is the message "- Unable to modify table.

i am using csFindProperty store procedure in my application. here there are several input parameter are there. my procedure structure are:
ALTER PROCEDURE [dbo].[csFindProperty] @HouseNumber varchar(10), @Street varchar(100), @City varchar(100), @State varchar(2), @Zip varchar(15), @County varchar(25), @SquareFootageStart int, @SquareFootageEnd int, @Bedrooms int, @Bathrooms decimal(18, 2), @Garage decimal(18, 0), @Basement bit, @StyleID int, @Subdivision varchar(50), @SchoolDistrict varchar(50), @MonthlyRentStart money, @MonthlyRentEnd money, @ListPriceStart money, @ListPriceEnd money, @PetsAllowed bit AS select distinct hd.housenumber,hd.street,hd.city,hd.state,hd.zip, rd.monthlyrent,sd.listdate, sd.listprice from housedata hd, rentdata rd, saledata sd where hd.HouseNumber like @HouseNumber and hd.Street like @Street and hd.City like @City and hd.State like @State and hd.Zip like @Zip and hd.County like @County and hd.SquareFootage >= @SquareFootageStart and hd.SquareFootage <= @SquareFootageEnd and hd.Bedrooms like @Bedrooms and hd.Bathrooms like @Bathrooms and hd.Garage like @Garage and hd.Basement like @Basement and hd.StyleID like @StyleID and hd.Subdivision like @Subdivision and hd.SchoolDistrict like @SchoolDistrict and rd.MonthlyRent >=@MonthlyRentStart and rd.MonthlyRent <= @MonthlyRentEnd and sd.ListPrice >= @ListPriceStart and sd.ListPrice <= @ListPriceEnd and rd.PetsAllowed like @PetsAllowed and hd.HouseDataID=sd.HouseDataID
if the user enter in the column HouseNumber=1733 that value passed in sp @HouseNumber = N'1733', suppose user can not type any value in the column HouseNumber means, i assign the value HouseNumber='%'. HouseNumber is a varchar datatype.
what my question is: if the column datatype money or int or bit means what is the value i assign @Bedrooms = 2, this situation. since bedrooms is int datatype. if i assign @Bedrooms ='%', conversion error will occur. pls any one can help me come out this problem.
I want to know how do we store null in the database
i know Null is unkown value
but it has to be something so the SQL server can know its null ( computer only knows 0s and 1s )
is it pointers and null does not have a pointer? or do we store something physically?
an example : we have string(varchar) column that has this value in it "Joey Tribbiani" that means in the hard disk we will see 14 bytes "Joey Tribbiani" in there, if we changed the value to "Monika" the 14 bytes will be replaced by 5 bytes "Monika", if we changed to empty strike then we will have 0 bytes ""
now if changed it to become NULL what is going to happen to the hard disk, what is going to be in there physically??
