Bigint As Unsigned Value?
Oct 4, 2006The documentation seems to suggest that I can store either a signed or unsigned value in bigint. If I want to store an unsigned value how do I go about it?

Unsigned 64-bit Value In T-SQL?
Mar 7, 2006I need to compute a BIGINT value in a SPROC that I'm writing. An intermediate value of the calculation is an unsigned value greater than (2^63-1) which I gather is why my SPROC is producing an arithmetic overflow error. I have a couple of choices as I see it:
1. Change the algorithm so that I don't have such large intermediate values (which would require me to add conditional statement which would slow down the SPROC and, therefore, I don't want to do).
2. Use the CLR integration with SQL feature to write my SPROC in C#.
My question is: Will 2. work or will the C# SPROC also produce an overflow once it is executed by the SQL Server?

Jan 17, 2005In MySQL you can define a unsigned integer as uint
But MS don't allow this. Only as int.
How can I define a column/field as a unsigned int ?

How Can I Set An Attribute Of Unsigned Zerofill In SQL?
Aug 6, 2007How can I set an attribute of unsigned zerofill in SQL? Like for example, there is an option in MySQL phpmyadmin to set the attribute of a specific column to unsigned zerofill, it will be based on the length of the integer. For example, the lenght of my int is 5, so if i'll set the attribute of the column to unsigned zerofill, the value that will be auto incremented will have zeroes before that actual value, for example000010000200003....00010and so on and so forth...But, how can i do this in SQL? I'm using MS SQL Server Management Studio Express, but I can't find the field attributes to set it to unsigned zerofill.. I hope somebody will reply in this post.. :(

Aug 1, 2004I need to stored lots of unsigned 32-bit values. (I'm actually storing IPv4 addresses). These values will frequently exceed 2^31 but never exceed 2^32
My options are:
Use bigint. This is undesirable since this wastes 32-bits of space for every value.
Use int and use the negative value range to get full 32-bits worth of data. In C, it is easy and fast to cast a signed -1 to an unsigned 2^32-1. In SQL, it will be more expensive: Must cast to 64-bit and if val < 0 then val = 2^32 + val.
Is there a better alternative?
Is there a fast (binary) way to cast a value > 2^31 to a negative signed value?

Trying To Map To Tinyint - Single Byte Unsigned Int Not Working
Mar 11, 2008I have an Excel spreadsheet that I eventually land into my staging table. In between, I'm attempting to get a date code from the Date table. I'm using a Lookup Transformation Editor and mapping the fiscal week of year and fiscal year name. I know the fiscal year name is fine. When I have both the fiscal year name and the fiscal week of year, the package fails on the lookup step. In a data conversion, I convert the fiscal week of year to a single byte unsigned integer. (In the Date table, the fiscal week of year is a tinyint.) I'm not sure what I'm doing wrong?
View 9 Replies View RelatedTo Bigint, Or Not To Bigint?
May 27, 2008Hey, quick question here. In my database for my webapp (The one I showed you guys in my previous post), in my stickies table, I am using a column called StickyId for the PK, and it is of type int. My concern is that eventually, I may get to a point with more then 2 million records in the stickies field. I am looking at using the bigint datatype for StickyId instead, but it takes up twice the memory. So I have two questions:1. Can I declare the StickyId column as type int for now, and if my DB ever starts approaching the 2 million mark, access my DB and change it over to a bigint type? Aka, will MS SQL convert the exisiting int values into a bigint and be transparent to the app and the users?2. Does the bigint always use 8 bytes to store its value? Aka does it pad, so that if I stored the value of '1' would that take the same space as if I stored the value '43563636'? Or is it more like varchar, only taking up the space that that particular value needs?Thanks in advance guys!

Mar 18, 2008Hi there! My question is: I use a bigint data type as a primary key in my database, so
1. Can I define bigint autoincrement as unsigned?
2. In case of possible, what type should I use in C# code that equal to bigint unsigned - ulong?
3. In case of impossible, what type should I use in C# code - long?

View 3 Replies View RelatedBigint And Int64 - When Fixed?
Nov 22, 2006I am attempting to build our first set of packages populating or DW. All of our source system primary keys are bigints (on the main tables at least). SSIS seems to have a problem dealing with bigint values, i.e. having to assign variables as doubles rather than int64, having to cast returning bigint values as float, or bigint sproc output parameters as double. It is all a bit messy (and possibly the most frustrating part of SSIS for me) - does anyone know if this problem is due to be fixed in any forthcoming release?
View 2 Replies View RelatedDTS Copy Truncates Bigint Values
Nov 24, 2003I just discovered that a bigint column in one of my tables is getting it's values truncated when I run a DTS job to copy the data to another database. The DTS job is designed to refresh our test environments from our production database. All the other tables copy fine. This include another table that also contains a bigint column. But this one table consistenly has a problem where 60 or so records are translated from positive number to negative values. The only explaination I came up with was truncation at some point.
Anyone know of a way to fix or work around this?
Datetime -&> Binary -&> Bigint (for Sorting)
Apr 20, 2007this is more of a theoretical question and not necessarily for best practice...though if reliable and efficient, i'd use it.
a lot of my sprocs return xml and are then processed in xslt...so when i need to sort by date (in xslt), i pass the datetime to a function that ultimately returns a bigint...it seems to work, but i'm not 100% confident...
can anyone confirm that the resulting integer values can be relied on for sorting?

Error When Updating Bigint Columns Using ADO
May 3, 2007I am attempting to write a conversion of our product for Compact Edition; we already provide it based on SQL Server. The database interface uses ADO through a Python-win32com adaptor, and has worked fine so far. (Note: *not* ADO.net, just plain old COM)
Now, a curious thing happens. When inserting new data through a Recordset, everything works fine - except for columns defined as bigint. There are no exceptions thrown, but when you read the columns back they contain nothing but zeroes. Do the same to any other column type - I've tried integer, numeric, float, nvarchar and ntext so far, and they all seem to work just fine. It does not seem to be conversion-related either, since I've tested the exact same data to various column types. And using bigint on regular SQL Server works just fine.
The code involved is quite unspectacular, and simply switching the column types to integer would solve the immediate problem, but causes potential future issues since we normally store internal IDs in bigint columns, and the values may grow quite large.

DB Engine :: Int -> Bigint And Resource Allocations
Jun 8, 2015I've got a problem: in few months from now my IDs (int) will reach max positive value. The only viable solution is to convert int-s to bigint-s.
There is a story behind this but I believe it's irrelevant. Simply, I need to 'upgrade' int-s to bigint-s; let's take it as a fact.
Question is: is there a formula to calculate increase in disk and RAM consumption? If we presume I'd need to have same number of pages in buffer cache, how can I calculate how much more memory I need?
Just to ease calculation, let's suppose that I have single table with 1e6 rows and 3 columns:
ID (int), PARENT_ID (int) and NAME (NVARCHAR(30)).
PK is on ID (let's call it PK_ID) and there are 2 indexes on PARENT_ID (i.e. IX_PARENT) and NAME (IX_NAME).
Now, if I turn int-s into bigint-s and still want to keep entire table in cache, how I can calculate how much memory I'd need?
Unexpected BIGINT Conversion Behavior
Jun 11, 2007
I've recently been struggling with moving a bigint data result from a query into an SSIS variable through the Execute SQL Task. Now, I could just be doing this incorrectly, but I couldn't get it to work at all if I made the variable int64 in SSIS. So here's what I found:
1. bigint from the query into int64 SSIS variable doesn't work at all. It fails.
2. bigint from the query into string SSIS variable works. BUT, it truncates it. And it's a crazy result, at least to me. All of a sudden the number 840550000000000 becomes 8405500000. Now, that's a really unexpected result to me. It seems to me this is a pretty crazy result.
3. Now, if I cast the bigint to varchar in the query and put it into a string SSIS variable, it works perfectly.
Is this a bug? If not, how is this expected behavior? Or maybe I'm just nuts after hours of futzing with this.
Thanks,
Michael

Return BIGINT OUTPUT Param To VB!?
May 9, 2006Please help me on this one.
I need to return a value to VB.
I've tried returning a numeric value NUMERIC(25,20) via an output parameter but this didn't work. I'm know at a point in wich I created a bigint and multiplied the value so that the decimals are gone. However it only returns NULL?!?!?!?!!?!?
Here's part of my stored proc
CREATE PROCEDURE dbo.uspCalcWeightedAverage @StartDate2 varchar(10), @EndDate2 varchar(10), @InMarket nvarchar(50), @InProductType int, @InWeekDay int, @WeightedAverage bigint OUTPUTAS......SELECT @WeightedAverage = cast(10000000000 * (SUM(HHF.FACTOR) / COUNT(PDF.FLAG)) as bigint)FROM TBL_PRODUCTDEFS PDF INNER JOIN #DATESBETWEENINTERVAL DBI ON DATEPART(HH, [DBI].[DATE]) = [PDF].[HOUR] INNER JOIN tbl_historichourlyfactors HHF ON DATEPART(D,DBI.DATE) = HHF.DayID AND [PDF].[HOUR] = [HHF].[HOUR] AND DATEPART(M,DBI.DATE) = [HHF].[Month]WHERE PDF.MARKETID = @InMarketID AND PDF.PRODUCTTYPEID = @InProductTypeID AND [PDF].[WD-WE] = @InWeekDay AND HHF.MARKETID = @InMarketID AND PDF.FLAG = 1GROUP BY FLAG
When I retrieve the output param it returns a NULL value. the properties in VB say that the parameter has the following props:

Core Data Type Question (bigint)
May 10, 2005We are trying to work with our developers to upgrade to SQL 2000 from SQL 7 for a critical applicaion and all looks good in testing for the most part. The concern that our developers have is that in order for the application to work on the test SQL 2000 server they had to delete a core data type (bigint) for the application to work. It doesn't appear to have any negative affects and we know for sure that the application database does not need that data type at all.
Can someone verify that there are no requirements for SQL 2000 needing to have this data type? They are worried that something within SQL may rely on it and we would find out the hard way in production possibly.
Change Datatype From Varchar To Bigint Not Working
Nov 14, 2007Hello,
I would like to change the datatype on a particular column from varchar to bigint across 100's of tables within a database.
I have the command ready which is:
ALTER TABLE tablename ALTER COLUMN columnname BIGINT
The problem happening is that it seems there are constraints across all the columns in every tables.
The error message is:
Server: Msg 5074, Level 16, State 1, Line 1
The object 'DF__tablename__columnname__0ABD916C' is dependent on column 'columnname'.
Server: Msg 4922, Level 16, State 1, Line 1
ALTER TABLE ALTER COLUMN columnname failed because one or more objects access this column.
I understand that if I delete this constraint, then it will let me modify the datatype of the column, but since there are tons of them and they are randomly named, how do I achive changing the datatype across multiple tables in bulk.
