I have this problem of inserting my query into database field. My code is as of below. The @AVERAGESCORE parameter is derived from Dim averagescore As Single = (122 * 1 + 159 * 2 + 18 * 3 + 3 * 4 + 0 * 5) / (122 + 159 + 18 + 3 + 0) and the value returned is (averagescore.toString("0.00")) However, I have error inserting the averagescore variable into a field of datatype float during the transaction. I have no problems when using non transactional sql insert methods. What could be the problem? Try Dim i As Integer For i = 0 To arraySql.Count - 1 myCommand = New SqlCommand Dim consolidatedobjitem As ConsolidatedObjItem = arraySql(i) myCommand.CommandText = sqlStr myCommand.Connection = myConnection myCommand.Transaction = myTrans With myCommand.Parameters
End With myCommand.ExecuteNonQuery() Next myTrans.Commit() myConnection.Close() Catch ex As Exception Console.Write(ex.Message) myTrans.Rollback() myConnection.Close() End Try
Am converting varchar field to float and summing using group by and next inserting to varchar field(table).
while inserting float value it is converting to exponential ex:1.04177e+006 but if i execute only select statment actual float value will get display ex:1041765.726
My question is why it is converting while inserting ? and how to avoid it.
Hi, I have a excel file and i am trying to import zip codes to the database... but the some of the zip codes start with 06902 but the excel file treats them as float but i want to treat them as varchar...
Hi all I have a Float Field in my table with following values:
1.63 7.42 35.71 0.58
every thing is ok BUT when i Select Data from this table in QUERY ANALIZER environment with (Select * from mytable) , Query Analizer shows me the following values:
How can I remove -1.#IND values from a float column in SQL Server 2000 (8.00.2039 SP4).
So far I've tried - Using Query Analyzer, setting the value to a proper float value. I receive error €œA floating point exception occurred€? - Using Query Analyzer, deleting the record with the invalid float. I receive error €œA floating point exception occurred€? - Using Enterprise Manager, setting the value to a proper float value. I receive error €œA floating point exception occurred€? - Using Enterprise Manager, deleting the record with the invalid float. I receive error €œA floating point exception occurred€? - Previously I was able to convert the column to nvarchar, but now this fails because the table is being replicated.
I don€™t really care what happens to the records, I just need them to go away.
In SQL Server for a field of datatype float(8), if i insert a value 2.62 , it saves it as 2.6200000000000001 like so for other values also. But in frontend i can see the right values.
STDEV() gives incorrect values with reasonable input.
I have a table filled with GPS readings. I've got a column LATITUDE (FLOAT) with about 20,000 records between 35.6369018 and 35.639890. (Same value to the first 5 digits of precision---what can i say, it's a good gps.)
Here's what happens when I ask SQL Server ("9.00.1399.06 (IntelX86)") to compute the standard deviation of the latitude:
// Transact-SQL StdDev function:
SELECT STDEV(LATITUDE) FROM GPSHISTORY WHERE STATTIME BETWEEN '2007-10-23 11:21:00.859' AND '2007-10-23 17:00:00.062' AND GPSDEVICEID = 0x004A08BC04050000;
0
// Zero. ZERO??!?!! //Let's re-implement Std Dev from the definition using other aggregate functions:
DECLARE @AVERAGE FLOAT; SELECT @AVERAGE = AVG(LATITUDE) FROM GPSHISTORY WHERE GPSDATE BETWEEN '2007-10-23 11:21:00.859' AND '2007-10-23 17:00:00.062' AND GPSDEVICEID = 0x004A08BC04050000; SELECT SQRT(SUM(SQUARE((LATITUDE - @AVERAGE)))/COUNT(LATITUDE)) FROM GPSHISTORY WHERE GPSDATE BETWEEN '2007-10-23 11:21:00.859' AND '2007-10-23 17:00:00.062' AND GPSDEVICEID = 0x004A08BC04050000;
6.03401924005392E-06
// That's better. Maybe STDEV is using fixed point arithmetic?!?
SELECT STDEV(10 * LATITUDE)/10 FROM GPSHISTORY WHERE GPSDATE BETWEEN '2007-10-23 11:21:00.859' AND '2007-10-23 17:00:00.062' AND GPSDEVICEID = 0x004A08BC04050000;
4.77267753808509E-06
SELECT STDEV(100 * LATITUDE)/100 FROM GPSHISTORY WHERE GPSDATE BETWEEN '2007-10-23 11:21:00.859' AND '2007-10-23 17:00:00.062' AND GPSDEVICEID = 0x004A08BC04050000;
1.66904329068838E-05
SELECT STDEV(1000 * LATITUDE)/1000 FROM GPSHISTORY WHERE GPSDATE BETWEEN '2007-10-23 11:21:00.859' AND '2007-10-23 17:00:00.062' AND GPSDEVICEID = 0x004A08BC04050000;
8.11904280806654E-06
// The standard deviation should, of course, be linear, e.g.
DECLARE @AVERAGE FLOAT; SELECT @AVERAGE = AVG(LATITUDE) FROM GPSHISTORY WHERE GPSDATE BETWEEN '2007-10-23 11:21:00.859' AND '2007-10-23 17:00:00.062' AND GPSDEVICEID = 0x004A08BC04050000; SELECT SQRT(SUM(SQUARE(100*(LATITUDE - @AVERAGE)))/COUNT(LATITUDE))/100 FROM GPSHISTORY WHERE GPSDATE BETWEEN '2007-10-23 11:21:00.859' AND '2007-10-23 17:00:00.062' AND GPSDEVICEID = 0x004A08BC04050000;
6.03401924005389E-06
// Std Dev is a numerically stable computation, although it does require traversing the dataset twice. // // This calculation is not being done correctly. // // Incidently, SQRT(VAR(Latitude....)) gives 4.80354E-4, which is also way off.
I will redefine STDEV to use a stored procedure similar to the above, but the algorithm used to compute VAR, STDEV etc should be reviewed and fixed.
I am importing a couple SAS datasets to SQL Server 2008 for a project. The dates are in a float format, they show up as DT_R8 in SSIS. How can I convert these values to SQL server datetime? I have tried dozens of methods I found on-line with no success, I keep getting 'Arithmetic overflow error converting expression to data type datetime.' errors.
Gurus, I have two list boxes, user can move items back n forth, from second listbox I am inserting values into a table. So far everything is working fine. Now I want to delete all the existing values from the table before inserting evertime..Please help me in this I dont know what to do. thanks kalloo
I'm trying to checking my production table table_a against a working table table_b (which i'm downlading data to)Here are the collumns i have in table_a and table_bDescription | FundID (this is not my PK) | Money I'm running an update if there is already vaule in the money collumn. I check to see if table_a matches table_b...if not i update table a with table b's value where FundID match up.What i'm having trouble on is if there is no record in table_a but there is a record in table_b. How can I insert that record into table_a? I would like to do all of this (the update and insert statement in one stored proc. if possible. )If anyone has this answer please let me know.Thanks,RB
I have a script that I use after some amount of data massaging (not shown). I would like to be able to change the
1) denominator value (the value 8 in line 32 of my code) based on how many columns are selected by the where clause:
where left(CapNumber,charindex('_', CapNumber)-1) = 1where capNumber is a value like [1_1], [1_4], [1_6]...[1_9] capNumber can be any values from [1_1]...[14_10] depending upon the specialty value (example: Allergy) and the final number after the equal sign is a number from 1 to 14)
2) I'd like to dynamically determine the series depending upon which values correspond to the specialty and run for each where: left(CapNumber,charindex('_', CapNumber)-1) = n. n is a number between 1 and 14.
3) finally I'd like to dynamically determine the columns in line 31 (4th line from the bottom)
If I do it by hand it's 23 * 14 separate runs to get separate results for each CapNumber series within specialty. The capNumber series is like [1_1], [1_2], [1_3],[1_4], [1_5], [1_6], [1_7], [1_8],[1_9] ... [8_4],[8_7] ... [14_1], [14_2],...[14_10] etc.
Again, the series are usually discontinuous and specific to each specialty.
Here's the portion of the script (it's at the end) that I'm talking about:
--change values in square brackets below for each specialty as needed and change the denom number in the very last query.
if object_id('tempdb..#tempAllergy') is not null drop table #tempAllergy select * into #tempAllergy from dbo.#temp2 T
[Code] ....
If I were to do it manually I'd uncomment each series line in turn and comment the one I just ran.
I can't take full credit for this. I want to share this with Jeff Moden who did the important research for this calculation here.
All I did was just adapting some old code according to the mantissa finding Jeff made and optimized it a little
Some test codeDECLARE@SomeNumber FLOAT, @BinFloat BINARY(8)
SELECT@SomeNumber = -185.6125, @BinFloat = CAST(@SomeNumber AS BINARY(8))
SELECT@SomeNumber AS [Original], CAST(@SomeNumber AS BINARY(8)) AS [Binary], dbo.fnBinaryFloat2Float(CAST(@SomeNumber AS BINARY(8))) AS [Converted], @SomeNumber - dbo.fnBinaryFloat2Float(CAST(@SomeNumber AS BINARY(8))) AS [Error]
And here is the code for the function.CREATE FUNCTION dbo.fnBinaryFloat2Float ( @BinaryFloat BINARY(8) ) RETURNS FLOAT AS BEGIN DECLARE@Part TINYINT, @PartValue TINYINT, @Mask TINYINT, @Mantissa FLOAT, @Exponent SMALLINT, @Bit TINYINT, @Ln2 FLOAT, @BigValue BIGINT
WHILE @Part <= 8 BEGIN SELECT@Part = @Part + 1, @PartValue = CAST(SUBSTRING(@BinaryFloat, @Part, 1) AS TINYINT), @Mask =CASE WHEN @Part = 2 THEN 8 ELSE 128 END
WHILE @Mask > 0 BEGIN IF @PartValue & @Mask > 0 SET @Mantissa = @Mantissa + EXP(-@Bit * @Ln2)
SELECT@Bit = @Bit + 1, @Mask = @Mask / 2 END END
RETURNSIGN(@BigValue) * @Mantissa * POWER(CAST(2 AS FLOAT), @Exponent - 1023) END Thanks again Jeff!
I have a webform that has 2 calendars that i use to insert a dateFrom and dateTo into a sql database table that has the type smalldatetime.

I have a few querys in the asp script. my problem is that the values from the query results to tables with float fiels, apear with a comma and want a dot
like area= 23,5 and I would like to have area= 23.5
in the query analyser there is no problem it´s all dots i have my web aplication running in 3 diferent machines and in 2 of them i dont have this problem. the query results to float fiels apear with a dot
in the 3 machines the database is the same , the odbc conection is similar. i have win xp professional in 2 machines and win 2000 server in other. the machine with this problem has xp pro

Hi all,I have a table called Jobs, with fields PK auto increment job_id, job_name, date. I'm using the visual web developer, .net 2.0, sql server 2005.I'm trying to have an option in one of my forms that allows me to add Jobs for a specific time frame. Say I want to add a job called "JobOne" and that I expect this job to last 2 months, so I would like to add this "JobOne" from October 1st 2006 to December 1st 2006. Than in the table "jobs" I would see JobOne in October 1st, 2nd, 3rd... all the way to December 1st. I'm familiar how to insert single values from formviews, using sqldatasources but I have no idea how to insert something like this, so I was wondering if anyone out there could help.Thanks!

What would be the best way to insert unique values into a table/unique column ? I cannot make that table/unique column as indentity. Right now, I use a staging table with indentity column, insert rows then insert rows back to final table.
I am trying to insert null values into sql server from my access from. I am using sql statement. But it says 'Syntex error in Insert statement'. When i remove null values it works fine? How can I insert null values into a table?
I need to insert some values into a table and after that catch the ID inserted. I set some input parameters in stored procedure and only one to get the @id defined as output SqlParameter paramIdPedido = new SqlParameter("@APP_IDPEDIDO", SqlDbType.Int, 4);paramIdPedido.Direction = ParameterDirection.Output;cmd.Parameters.Add(paramIdPedido); Do I have to run cmd.ExecuteNonQuery(); to record first what I need and afterrun ExecuteReader: something like SqlDataReader dr = cmd.ExecuteReader();while (dr.Read()... to get the ID) From stored procedure: INSERT table(fields) VALUES(vars)SELECT TOP 1 @id = id FROM table ORDER BY id DESC I must do all these steps or maybe is there anything less complex to do? Thanks!
Hi, I am trying to insert multiple values from another table as well as an addition value defined by me. Here's my code which is obviously incorrect at the AND statement: Insert Into table_1 (ID, Col_1, Col_2)Select ID, Col_A, Col_B From table_A AND table1.Col_3 = 'XYZ' Where table_A.Col_A IS NOT NULL
Pls advise on the correct way of constructing this statement. Many Thanks
Hi all, I am having issue with a set of radiobuttons. I have four radiobuttons associated by a groupname (answer). I am attempting to store the text of the selected radiobutton when the user make a selection and clicks submit. For reasons unknown... each of the radiobutton.checked values are remaining false hence I cannot interrogate for a checked equal true to insert associated text of check response. Here is how I am interrogating who is checked: If rb1.Checked = True Then useranswer = rb1.Text.ToString ElseIf rb2.Checked = True Then useranswer = rb2.Text.ToString ElseIf rb3.Checked = True Then useranswer = rb3.Text.ToString ElseIf rb4.Checked = True Then useranswer = rb4.Text.ToString End If I then attempt to insert this text to sql but none of the rb values are true hence a null wont insert. Cmd1.Parameters.Add(New SqlParameter("@answer", useranswer))
How can I evaluate grouped radiobutton checked values? Many thanks in advance... Scott
Hi All, am new to sql server in my application I am having one Asp.net web page, the user has to enter values for 5 fields(Empno,Empname,salary,deptno,deptname) in that web page and for that i created two tables in sql serverEmp Table- empno(primary key),empname,salaryDept Table- Deptno(primary key),empno(Foreign key ),Deptname(with some check constraint.) After the user enter all the values in the Asp.net web page now i want to store data into database for that i wrote the following stored procedure...create procedure usp_EmpDept @empno integer, @empname varchar(15), @salary money, @deptno integer, @deptname varchar(10) As Insert into emp(empno,empname,salary)values(@empno,@empname,@salary) Insert into dept(deptno,Empno,deptname)values(@deptno,@empno,@deptname) but the problem is whenever some constaint violation for eg. if some check constraint violation in Dept table its inserting the values in the Emp table only, but my requirement is, It must enter into both tables if there is no constaraint violation otherwise it has to ignore both the tables. And also please suggest is there any better way to insert values into two tables other than using the stored procedure Any help will be greatly appreciated..Thanks,Vision..
i have a table whose Primary Key is "UserID". the sample "UserID" are M1,M2,M3,M4,B1,B2,B3 . i want that when i insert a valuse "M4" in the table ,by pressing Submit Button. it should not be at the end or at the start of table. Rather it should be next to M3. like the following M1 M2 M3 M4 M5 B1 B2 B3 i need the C# code of how to do that !!!! Thanks
Is there a way to insert multiple values into a single column based on various "tests". For example, I want to check a sales_order table and flag all new orders coming in against previous orders placed that were determined to be fraudulent. If I were to set up i.e. five different tests(i.e. check email, credit_card number etc. against previous fraud orders), then there would be the possibility that any given order can be flagged 1 to 5 times. I want to record all of these tests within the same column if possible. Therefore the output may look something like the following:
order_number fraud_score 1234567890 a,b,d 5432109876 e 2345678901 null 3455607983 a,b,c,d,e
I was considering adding five additional columns to the table and running five different update steps, but this doesn't appear very scalable. Any suggestions would be greatly appreciated! thanks in advance- trevorb
We are using an SQL Server database and seem to be having some problems with inserting null values into numeric fields. The field is set to accept nulls, but when we try and write a record into the database and that field is null, the application craps out on us. Are there any issues that we should be aware of when inserting null values into numeric fields? What might the problem be? Thanks.
I am fetching values from a table containing non english characters and inserting the values in another table. Both the tables have the same structure and the column datatype is nvarchar. I am using jdbc jtdc.jar with default parameters. When I query my inserted values, they are junk characters. when I insert values using Query Analyzer the characters are proper. But when i insert using jdbc junk values are stored.
When the first TrackCodeid is NULL all remaining NULL TrackCodeid is entered as null in the database table but if the first/prev trackcodeID is not NULL then following null trackCODEID is populated with the prev trackcodeID and not as null in database <TrackCodeId>ABCDEFG</TrackCodeId> All Null TrackCOdeID is populated as ABCDEFG if we remove ABCDEFG and then bulkload all null values are populated if a null trackCODEID is to be inserted the prev trackCODEID must be null and must not contain any value
