I have a table Saleshistory with 89481412 records. I have a field Sales of nvarchar type, all the records in this field are numeric, and the records are with 2 decimal places. I expect all the records to be ending at .00 (for example 5.00,345.00,25.00), but I want to verify if something is for example 5.6 etc.
So in short I want to check if any Salesrecords have more than zero values in the decimal. How can I check this.
I have a field defined as varchar(8) but this field should not contain any letters, needs to be only numbers. How can I validate the data if it contains only numbers? Any ideas?
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 have SQL Server 2012 SSIS. I have Excel source and OLE DB Destination.I have problem with importing CustomerSales column.CustomerSales values like 1000.00,2000.10,3000.30,NotAvailable.So I have decimal values and nvarchar mixed in on Excel column. This is requirement for solution.However SSIS reads only numeric values correctly and nvarchar values are set as Null. Why?
I have a problem with SQL rounding my decimals up when I pull them from a temp table that has the column set as VARCHAR. What is happening is I am pulling the info from a flat file but each column has "" around each field so I must make the temp table columns all VARCHAR so I may pull the info from the file properly. So after the info has been extracted, I run an update statement on the temp table to remove all quotes. Once this is done, the revised info is inserted into a staging table and any field that is a represented as a decimal is labled as such in the staging table.
What I am running into is when the info is inserted into the staging table, the decimals are rounded up to whole values. The column has been checked to verify that it is indeed a decimal. I even have a CAST statement in the insert hoping to combat the rounding issue, but it is not helping.
So what reason(s) would my decimals be rounding up?
I have a field in my database that is stored as varchar. The values are usually contain a decimal, and should have really been a float or decimal. In order for me to do analytics in my BI environment, I need to convert this to a float or decimal.
eg of values.
10.00 20.00 0.00 15.00
or could be missing when I use cast(value as float) or cast(value as decimal(9,2)) or convert(float, value) I get an error
There is a MSSQL function that check the value. Like ISNULL(), ISDATE() and ISNUMERIC(). I don't see a function that check for decimal. If there isn't any then is there an user-defined function for it? I need to be able to validate the string value for decimal before it get assigned to a decimal datatype or T-SQL will run into an error.
So my data is delivered as numeric(9,2)...like 100.00. I have to extract that data and store it as a varchar 0 filled without the decimal place...like 0000010000///I tried the following and it did not work...
Can't seem to get my head around this: I'm looking for a way to select only those varchar(10) values that soley consist of numbers. Leading spaces are allowed.
I tried using isnumeric, but it also allows those with periods, comma's etc. Also tried using like, but the length of the varchar column varies too much to do a like '[0-9][0-9]....'.
As a solution I currently do a combo of isnumeric, not like '%.%', not like '%,%' etc. I need to do a conversion to an int to join another table, but the convert still fails. Not sure where and why.
I'm thinking there should be a better way than create a hughe list of "not like " but it looks like I'm in the woods here...
I have a column set to varchar(12) so I can ensure that the length of the string entered will never be more than 12 characters but I want to limit the string to a minimum of 8 characters, so I end up with a string that is from 8-12 characters long. How do I ensure the minimum length of 8 characters? I'm using SQL Server 2005 if that helps. I tried adding a check constraint like so:
DATALENGTH(UserName) >= 8
But I keep getting an error when I save the table, so any help would be very much appreciated.
it is my first post on this forum, please be patient if i miss any important bit of information.
i am transporting data from a legacy system into mssql 2k5 using SSIS. among those column of a dataset there are 13 columns, all necessary for operational reasons, that i need to ensure data consistance.
i believe i could do this check using the lookup data flow item, but surely there must be a way to do it in a more streamlined fashion.
since column names contain numbers to distinguish the version, eg; col01, col02, col03 .. col13.
i thought i could include the lookup within a loop and use a couple of variables to do this trick, but since i have not done it before i am asking for some sort of guidance from a guru among you folks.
please let me know if further clarification is necessary.
I am trying to setup an indicator value for an SSRS report to show green and red values on a report, based on the NRESULT value. The problem I am facing is that I have several different CASE statements that have the same logic, and they are processing just fine. NRESULT is a decimal field, so no conversion should be necessary. I do not know why I am getting the "Arithmetic overflow error converting varchar to data type numeric." error message.
Below is the CASE statement where the error is occurring. It is in the part of the ELSE CASE. The first CASE works just fine when the ELSE CASE is commented out. If I also change the ELSE CASE statement to say "else case when LEFT(NRESULT,1) = '-' then '0'", then it processes fine, too, so it has to be something I am missing something in the check on negative values. I do need the two checks, one for positive and one for negative values, to take place.
case when LEFT(NRESULT,1) <> '-' then --This portion, for checking positive values, of the CASE statement works fine. CASE WHEN LEFT(ROUND(NRESULT,2),4) between 0.00 and 0.49 THEN '2' --Green ELSE CASE WHEN LEFT(ROUND(NRESULT,2),4) > 0.49 THEN '0' --Red ELSE '3' --White END END else case when LEFT(NRESULT,1) = '-' then --This portion, for checking negative values, of the CASE statement is producing the conversion error message.
[code]....
I checked the NRESULT field, and there are not any NULL values in there, either.
The values that are being fetched from the database are not being read as is , when there are decimal values with 10 or more digits after the point, the values are truncated (approximated) to 8 digits
The approximation is not consistent in all the cases Some times depending on the numbers for example 0.434000001 is truncated to 0.434.
This is happening when i read the values from the sql database using the SqlDataReader.GetValue method into an ArrayList in C# .NET
I have an SQL search that is converting two values to type money. I want it to show two digits after the decimal point but am getting inconsistent results. The first value is as follows:
tblInventoryItem.itemcost as originalcost (the column is datatype money)
This displays correctly i.e. 2000.00 or 150.70 etc
The second value is this:
tblInventoryItem.itemcost + tblUpgrades.ItemCost as totalcostincupgr (both columns are datatype money)
But this displays as 2000 or 150.7
How can I get the second value to show two decimal places even when the digits are zeros?
Hi. I I'm importing a text file with lot's of decimal values with this format xx.xx. The problem is that my locale is Portugal and the points are being striped off and are not being considered as decimal separators (for example I have values like 0.04 and in the sql server database i see 4). I have tried to change the locale but i receive a message saying that the locale is not installed in my system.
I want to find out if a ceratin column has values with decimal figures populated? for example say column A has values
10.00 20.00 30.00 50.01
in this case the query should let me know that there is one figure (50.01) with a actual decimal value. So the results of the query should be 1 (since one record has decimal figures <>.00)
Hi, I want to transfer the data from a excel spread sheet to sql server. I have used the oledb comand and it works fine, and i have also used the sqlbulkcopy and it transfers the data properly. But in my excel spread sheet i have many columns with data as -0.76 or 0.76 or something like that but when it transfer it to sqlserver that particular column in sql server shows it as 0.00762711864406778 So how i can i tell sql server to display the data as 0.76 instead of 0.00762711864406778
hi, i'm using the following code to generate the value of a column in a database, where the colums value is dependent upon the multiplication of two other cells in the same row. When I execute the statement, it will work fine for whole numbers, but it does not work correctly for decimal values. All columns are of type varchar(50). An exmple.................It just multiplied 200 by 2.50 and returned 600SqlCommand objCmd2 = new SqlCommand("UPDATE Portfolio SET Current_Worth=Current_Price*Number_Of_Shares WHERE Name_Of_Asset LIKE '%'+@Name_Of_Asset+'%'", objConn);objCmd2.Parameters.AddWithValue("@Name_Of_Asset", DropDownList1.SelectedValue);objConn.Open();objCmd2.ExecuteNonQuery();objConn.Close(); Any ideas?
The string column value looks like as below. Each value has a size of 15 withing a string
'2.2020 30 4.0000'
The column value should match with user input as below. The result should show equal when it is compared. Currently, it results not equal since it is a string comparision. The last digit '0' needs to be ignored for decimal values.
'2.202 30 4.0'
I need to handle the decimal values in such a way, if staring value with '.' and last digit is 0 then replace with space ''. So, it should look like
'2 2 2 30 4 ' = '2 2 2 30 4 '
When this string is compared, it results in EQUAL.
I tried the below logic, which even replaces the integer value like 30 to 3 and 3000 to 3 and results in equal which is incorrect.

I am importing an excel spreadsheet into a MS SQL database table. When the spreadsheet is finished importing, I am noticing that some values that were brought in resemble something like this 1.41666666666667. Other values may be shorter or only have 1 digit. The problem is another web application that pulls this data for use in online forms only allows up to 2 digits. How can I round all of the numbers like the above to 2 decimals and replace the existing values?
I know there is the rounding function that could be used like so:
SELECT ROUND ([Hrs Total 2],2) FROM AnnualClassifiedPAFs
How do I then take that rounded value and insert it back into the records?
I am relatively new to SQL and as a project I have been asked to create the SQL for a simple database to record train details. I want to implement a check constraint which will prevent data from being inserted into a table if the weight of the train is more than the maximum towing weight of the locomotive. FOr instance, I need to add the unladen weight and maximum capacity of each wagon (located in the wagon type table) and compare it against the locomotive maximum pulling weight (the locomotive class table). I have the following SQL but it will not work:
check((select SUM(fwt.unladen_weight+fwt.maximum_payload) from hauls as h,freight_wagon as fw,freight_wagon_type as fwt,train as t where h.freight_wagon_serial_number = fw.freight_wagon_serial_number and fw.freight_wagon_type = fwt.freight_wagon_type and h.train_number = t.train_number) < (select lc.maximum_towing_weight from locomotive_class as lc,locomotive as l,train as t where lc.locomotive_class = l.locomotive_class and l.locomotive_serial_number = t.locomotive_serial_number))
The hauls table is where the constraint has been placed and is the intermediary table between train and freight wagon.
I may not have explained this very well; but in short, i need to compare the sum of two values in one table against a values located in another table...At present I keep getting a message telling me the sub query cannot return more than one row.
Not sure how I can convert varchar to numeric values in SQL Server? Trying to do so in Design and get error: Unable to modify table. ODBC error: [Microsoft][ODBC Server Driver][SQL Server] Error converting data type varchar to numeric. Any suggestions?
I have a stored procedure that accepts a parameter of type varchar(32). This parameter gets tested against NULL as part of an IF statement. The behavior I'm seeing is that this test never evaluates to TRUE, even in cases where NULL has been passed in as the value of the parameter.
CREATE PROCEDURE uspNewVital @Description varchar(32), @Type tinyint, @DeviceType varchar(32), @Dimension varchar(32), @Unit varchar(32) AS IF (@Dimension != NULL AND @Unit != NULL) BEGIN RAISERROR ('You must specify either a dimension or a unit.', 15, 1) ; RETURN 0 ; END IF NULL = @Dimension BEGIN DECLARE @UnitID AS int ; SELECT @UnitID = ID FROM tblUnit WHERE Description=@Unit ; IF @@ROWCOUNT = 0 BEGIN RAISERROR ('Unit not found.', 15, 1) ; RETURN 0 ; END INSERT INTO tblVitalType VALUES (@DeviceTypeID, @DatumID, NULL, @UnitID) ; END ELSE BEGIN DECLARE @DimensionID AS int ; SELECT @DimensionID = ID FROM tblDimension WHERE Description=@Dimension ; IF @@ROWCOUNT = 0 BEGIN RAISERROR ('Dimension not found.', 15, 1) ; RETURN 0 ; END INSERT INTO tblVitalType VALUES (@DeviceTypeID, @DatumID, @DimensionID, NULL) ; END GO
When I pass in a NULL for @Dimension, code execution still goes to the ELSE block.
At first I thought this might have something to do with the ANSI_NULLS option, but the database has this defaulting to OFF.
Any insights would be greatly appreciated. Thank you.
I am using the varchar data type in sql to store a comma-delimited string of multiple selections from a checkboxlist.
The string only has about 28-30 characters in it, but it maxes out the sql row length and I get the 8060 error message every time.
Here is some of the code:
"Dim industry1list As String Dim li As ListItem industry1list = "" For Each li In industry1.Items If li.Selected = True Then industry1list = industry1list & li.Value & "," End If Next .... MyCommand.Parameters.Add(New SqlParameter("@industry1", SqlDbType.VarChar, 60)) MyCommand.Parameters("@industry1").Value = (industry1list)"
I would appreciate any coaching you have for me to get back on track. Thanks, Bob
