I am new to SQL Server and am trying to figure out why it behaves the way it is regarding integers with null values.
I have a table that contains integer datatypes which can be null. If i insert the record with a blank field i receive an INCORRECT SYNTAX NEAR ',' error. If i surround the form value with '', it inserts a 0. Why does SQL Server behave like this? And whats the proper way to handle inserts such as this?
Thanks!
I need to convert a a string column to integer. Before converting, I need to check if it has blank values then convert it to NULL. Someone told me that its easier to convert it to NULL before converting to integer.
View 5 Replies View RelatedI have a pivot transform that pivots a batch type. After the pivot, each batch type has its own row with null values for the other batch types that were pivoted. I want to group two fields and max() the remaining batch types so that the multiple rows are displayed on one row. I tried using the aggregate transform, but since the batch type field is a string, the max() function fails in the package. Is there another transform or can I use the aggragate transform another way so that the max() will work on a string?

I have to use the above comma separated values into a SQL Search query whose datatype is integer. How would i do this Search query in the IN Operator of SQL Server. My query is :
declare @id varchar(50)
set @id= '3,4,6,7'
set @id=(select replace(@id,'''',''))-- in below select query Id is of Integer datatype
select *from ehsservice where id in(@id)
But this query throws following error message:
Conversion failed when converting the varchar value '3,4,6,7' to data type int.
Hi,I have SQL Server DB, and I tried to insert some data.

I'm using a table to hold data that I can pass back to the original form page and re-populate the fields that were not validated correctly. The stored procedure either inserts or updates the record in the temp table I've created.
So, currently, as I'm testing, I'm just passing empty values to all the parameters and the @state parameter is failing and throwing the error.
I've double checked that the table has the state column set to integer datatype
The column is set as follows:
Name datatype length Allow Nulls
----------------------------------------------
State int 4 checked
I have tried setting the default value for every column to Null in the table and then also not using a default value. Either way, I still recieve the same error?
Not sure what else to look at?
It seems the problem might be that instead of a null value being passed to the parameter that it is actually empty. Can passing an empty value to a column of datatype integer cause this problem? If so, is there a way to correct it?
Thanks for any help.
I've got a function which inserts into a database, and has arguments for each item being inserted
A couple of the items are integer datatypes (in SQL), but they will accept nulls
When I add my parameters, it asks to explicitly use the SQL datatype (which is integer):.Add("@myParam", SqlDbType.Int).Value = myParam
In the header of the function, I assumed I could make the argument optional - Optional ByVal myParam as Integer=System.DBNull.Value
However, when the function runs, I always get an error:System.InvalidCastException was unhandled by user code Message="Conversion from type 'DBNull' to type 'Integer' is not valid."
I make them all Optional (which won't happen, but various arguments may be, at different timesand I get this error, with the last item (which is on a separate line), in red:Constant expression is required.
How can I get around this?
Following on from some problems I have been having with flat files, I seem to be stumbling from one issue to another.
I have coded my text file with some very contrived delimiters to ensure that my real data isn't tripping up the package. I am stripping all line break chars, tabs etc.
Now I seem to get all rows imported, but numerous integer columns within the file are being set to zero.
When I toggle the Keep Null options in the data flow task it will either import the row, but with the zeros, or not import the row at all. I have opened the file in text editors, and Excel and it all seems fine - in fact the same source file works OK with DTS/2000.
At a guess it seems as though these columns are seen as null by the package and so with the option switched on it defaults to zero - but they are most certainly not null in the file!! The table is a staging tabe and so is very basic in structure (no defaults or constraints)
SSIS seems a bit buggy or at the very least over sensitive to me - I am at the point of abandonment of it!!
Please has anyone seen similar issues?
I have a simple flat file which I am trying to import which has 50k rows and about 50 columns. File is delimited (using a rather obscure multiple char delimiter) with text delimiting also.
When importing if I check the "Retain null values from the source" it will import the columns correctly but drop approx 7k of the rows.
If I uncheck this box it imports all rows, but on the second integer column in that target table all values are inserted as zeroes when there is at least 35k rows with a positive value.
I have put a data viewer on this import and it's also showing zeroes.
I'm tearing my hair out!!
Just to be clear i'm using a cube here.
Okay if i understand correct if you want to sort your parameter list you have to write an MDX query.
Thats all good and well i've been able to sort my parameter list when its a string
WITH
MEMBER [Measures].[ParameterCaption] AS '[Time].[Week].CURRENTMEMBER.MEMBER_CAPTION'
MEMBER [Measures].[ParameterValue] AS '[Time].[Week].CURRENTMEMBER.UNIQUENAME'
MEMBER [Measures].[ParameterLevel] AS '[Time].[Week].CURRENTMEMBER.LEVEL.ORDINAL'
MEMBER [Measures].[DefaultValue] AS '[Time].[Week].CURRENTMEMBER.UNIQUENAME'
MEMBER [Measures].[DefaultBeginValue] AS ' ( "[Time].[Week].&[" + LEFT([Time].[Week].CURRENTMEMBER.MEMBER_CAPTION,4) + "-01]" ) '
SELECT {
[Measures].[ParameterCaption],
[Measures].[ParameterValue],
[Measures].[ParameterLevel],
[Measures].[DefaultValue],
[Measures].[DefaultBeginValue]
}
ON COLUMNS
, {
Filter ((ORDER({(Filter ([Time].[Week].MEMBERS,( [Time].[Week].CURRENTMEMBER.MEMBER_CAPTION ) <> 'Unknown'))},
([Time].[Week].CURRENTMEMBER.UNIQUENAME) , DESC)),
( [Time].[Week].CURRENTMEMBER.LEVEL.ORDINAL ) = 1)
}
ON ROWS FROM [Europe]
Now my problem is that this value of this string is actually an integer. The reason this is a data type string is because its a dimension and these are always string only measures are integer...
Can someone help me make this MDX query sort on integer value instead of string.
[Time].[Week].MEMBERS contains values like 8,11,20 but is declared are string because its a dimension please help me out because i'm getting the feeling this is impossible with this microsoft tool...
We have inherited an appointments database that has a table tblAppointments
Within this table there are 2 fields, ApptFrom & ApptTo, these are the appointment start & finish times.
My problem is, the values in these fields are held as integers ranging from 0 - 288. I have worked out the scale for the integers, it is based on a 24hr clock with each segment representing 5mins
Eg: 0 = 0:00
12 = 1.00
24 = 2.00
36 = 3.00
€¦
...
288 = 24:00
What I need is a piece of T_SQL that will translate these into times that can be read by a normal user
So, say I have a record with an ApptFrom = 36 & ApptTo = 42, I need to be able to show these as ApptFrom = 3.00 & ApptTo = 3.30
Any help is greatly appreciated.
Cheers,

I have imported a text file with various data into sql table. all these values have been imported as nvarchar. I need to convert these into Integer. the format of the values is 10length i.e. 0000000.00.
example of data:
0001028.99 - needs to be shown as 1028.99
222.00 - needs to be shown as 222.00
0000190.89 - needs to be shown as 190.89
2708.99 - needs to be shown as 2708.99
00000-50.99 - needs to be shown as -50.99
-109.79 - needs to be shown as -109.70
as you can see some of the values have leading zeros and some don't.
i have tried converting from nvarchar to int and i get the error cannot convert nvarchar to int, i believe it may be because the data contains negative values as well as positive values.
Is there a split function or position function which i can use to extract the data? or any other methods which i can use would be really helpful.
Thanks

As a DBA, I am working on a project where an ETL process(SSIS) takes a long time to aggregate and process the raw data.
I figured out few things where the package selects the data from my biggest 200 GB unpartitioned table which has a datekey column but the package converts its each row to an integer value leading to massive scans and high CPU.
Example: the package passed two values 20140714 and 4 which means it wants to grab data from my biggest table which belongs between 20140714 04:00:00 and 20140714 05:00:00.
It leads to massive implicit conversions and I am trying to change this.
To minimize the number of changes, what I am trying to do is to convert 20140714 and 4 to a datetime format variable.
Select Convert(DATETIME, LEFT(20170714, 8)) which gives me a date value but I am stuck at appending time(HH:00:00) to it.
I'm looking for a script that identifies max values used in a table for all smallints, ints and bigints to determine if they are being used correctly.

View 3 Replies View RelatedI have a DTSX package which reads values from a fixed-length text file using a data reader and writes some of the column values from the file to an Oracle table. We have used this DTSX several times without incident but recently the process started inserting NULL values for some of the columns when there was a valid value in the source file. If we extract some of the rows from the source file into a smaller file (i.e 10 rows which incorrectly returned NULLs) and run them through the same package they write the correct values to the table, but running the complete file again results in the NULL values error. As well, if we rerun the same file multiple times the incidence of NULL values varies slightly and does not always seem to impact the same rows. I tried outputting data to a log file to see if I can determine what happens and no error messages are returned but it seems to be the case that the NULL values occur after pulling in the data via a Data Reader. Has anyone seen anything like this before or does anyone have a suggestion on how to try and get some additional debugging information around this error?

Hi
can somebody explain me how I can assign a NULL value to a datetime type field in the script transformation editor in a data flow task.
In the script hereunder, Row.Datum1_IsNull is true, but still Row.OutputDatum1 will be assigned a value '0001-01-01' which generates an error (not a valid datetime). All alternatives known to me (CDate("") or Convert.ToDateTime("") or Convert.ToDateTime(System.DBNull.Value)) were not successful.
Leaving out the ELSE clause generates following error: Error: Year, Month, and Day parameters describe an un-representable DateTime.
If Not Row.Datum1_IsNull Then
Row.OutputDatum1 = Row.Datum1
Else
Row.OutputDatum1 = CDate(System.Convert.DBNull)
End If
Any help welcome.
Hi,
My query "select blah, blah, rank from tablewithscores" will return results that can legitimately hold nulls in the rank column. I want to order on the rank column, but those nulls should appear at the bottom of the list
e.g.
Rank Blah Blah
1 - -
2 - -
3 - -
NULL - -
NULL - -
At present the NULLs are at the top of the list, but I do not want my ranking in descending order. Any suggestions?

Working on a new database where the Date and Time are stored in a Date Time Field.
Then working on an OLDER database file within the same SQL Database contains these 2 items as integers:
transDate = "71615" (July 16, 2015)
transTime = "12345" (01:23:45 AM)
How do we convert both of them into a single SQL DateTime field such as "2015-07-16 01:23:45.000" so that it can be used in a join restricting to a date time in a different SQL File that properly has the DateTime in it?
This works well for converting the transDate Part in the select statement:
  dbo.IntegerToDate(at.transDate) as transDate
  * That returns: "2015-07-16 00:00:00.000"
* The resulting data must work directly in a Microsoft SQL Server Management Studio Query using either using the "on" statement or part of the "where" clause. In other words, NOT as a stored procedure!
Also must be able to be used as a date difference calculation when comparing the 2 files Within say + or - 5 seconds.
I have an SSIS package that imports data from an Excel file, replaces any value in Excel that reads "NULL" to "", then writes the data to a couple of databases.

I don't know why it is creating links inside my SP -ignore them. TagNum is the primary key, if that makes a difference.
On the webpage, it ONLY works when every field has been filled (and then it will only return 1 row, as it should, given the data entered). Debugging has shown that when nothing is entered it passes "".

What's throwing me off is that there are multiple a.asset or b.asset for each unique ID. It seems to work, but I'm not following the logic too well. If I were doing this in another language, I would loop through, summing a.asset and b.asset wherever it's not null for each unique ID.
Hi,
How can I use "Derived Column" to check if a Datetime value is null or not and if null to insert 00/00/00 instead. ?
The background being that while using a "Derived Column" to change a Column from a (DT_DATE) to a (DT_DBTIMESTAMP) everytime I get a null value it see's it as a error.
And the column in particular has ~ 37 K blank / null fields so Im getting a lot of errors
So far I have tried to use something like
ISNULL([Column 34])
Or
SELECT ISNULL(ID, '00/00/0000') FROM [Column 34]
Or
SELECT ISNULL(au_id, '00/00/0000 00:00') AS ssn
FROM [Column 34
but none seems to work [Column 34] being the offending column.
What a normally use is just a simple "(DT_DBTIMESTAMP)[Column 34]"
in the expression column, which seems to work well, but here I get alot of errors
Any ideas?
I set up a new SQL database file, in that file I allowed nulls, When I went through code to save the record, the exception is saying it doesnt allow nulls.
Before I get to involved with SQL, is it a bad practice to use nulls?
If it is what do you enter in place of the null value,
which will lead to more code, right?
