I have a table of sales transactions that I'd like to group by date, but this is a datetime field so it groups by the date and time, and so it returns more records that I want. Is there an easier way to do this other than using the datepart function to build a date? How can I just look at only the date of a datetime field?
I am re writing my help desk app so that it can use popular databases at the backend. Although I am OK with MySQL I have no experience with MsSql. Most of my querys are standard stuff, but I have some datetime querys which I need help with.
Firstly can I use iso date times (yyyy-mm-dd hh:mm:ss)
How would I convert the following MySql query to MsSql or could someone point me in the right direction to get the required info?

I need some help with some date functions: this is how they are stored in the database '5/4/2007 1:00:00 PM' if i were to query a list of all records with todays date, how do i achieve that. also if i were to set a query to fetch all records within a two week date range how do i so that
i have tables customer id name address city items itemid code itname cost sales sid invno date cid amount (what are the sales done in date) purchases pid invno date cid amount (what are the purchases done in date)
dsales dtsid sid code qty cost amount (detail of sales) dpurchase dtpid pid code qty cost amount (details of purchases)
i want a query like

i'm new to sql and i'm working on a hoilday datebase and i need to create sql query where the finish and start dates are shown but i only have the finish date and the duration of the hoilday and i'm not sure how to show the start date.
Hi all,Are there a functions for last day of the month or first day of the month?Thanks in advance,Jen--Fast Track On Line -Web Design and DevelopmentPortfolio http://www.fasttrackonline.co.uk---Outgoing mail is certified Virus Free.Checked by AVG anti-virus system (http://www.grisoft.com).Version: 6.0.688 / Virus Database: 449 - Release Date: 18/05/2004
We are using [DATE] [TIME] functions in SQL Server 2000 agent jobs and SQL Server use to translate it to current data and time functions but in SS2005 it is not replacing the functions and we are getting filename as "test_DATE_TIME" whereas we expect "test_20071204_130000" Do we have any new functions as replacement?
Thanks --rubs
Following is the code we are using: declare @name nvarchar(100) declare @name1 nvarchar(100) set @name1 = 'test_[DATE]_[TIME]' set @name = 'c:ackup' + @name1 + '.bak' backup database test to disk = @name
dbo.TAG ON dbo.KALENDER.KALENDER_ID = dbo.TAG.KALENDER_ID INNER JOIN
dbo.STUNDE AS s ON dbo.TAG.TAG_ID = s.TAG_ID
WHERE ((SELECT MONTH(s.datum_zeit) AS Expr1
FROM ) =
(SELECT MONTH(GETDATE()) AS Expr1) - 2) AND
((SELECT YEAR(s.datum_zeit) AS Expr1
FROM ) =
(SELECT YEAR(GETDATE()) AS Expr1))
ORDER BY s.STUNDE_ID
... but this causes syntax-errors. I don't understand why this query works fine in the query editor but then gets automatically "destroyed" by the view editor. Do i have to use more statements to get the working query to run inside a view?
I have received an alert on a server that is running SQL 2005. 'The service pack level of SQL instance is not upto date'.
I have right clicked the connection properties and found that current version is 9.00.1399.06 How can I tell which Service pack the SQL 2005 is currently on?
Do you know of any articles to upgrade service packs?

I need to get the last value of # Orders week avg in the current context (the highlighted value). The calendar dimension here is a week level one so I don't think I can use LASTNONBLANK. The measure is from the facts_sales table which is linked to a calendar dimension via a date key.
I was playing around with the new SQL 2005 CLR functionality andremembered this discussion that I had with Erland Sommarskog concerningperformance of scalar UDFs some time ago (See "Calling sp_oa* infunction" in this newsgroup). In that discussion, Erland made thefollowing comment about UDFs in SQL 2005:[color=blue][color=green]>>The good news is that in SQL 2005, Microsoft has addressed several of[/color][/color]these issues, and the cost of a UDF is not as severe there. In fact fora complex expression, a UDF in written a CLR language may be fasterthanthe corresponding expression using built-in T-SQL functions.<<I thought the I would put this to the test using some of the same SQLas before, but adding a simple scalar CLR UDF into the mix. The testinvolved querying a simple table with about 300,000 rows. Thescenarios are as follows:(A) Use a simple CASE function to calculate a column(B) Use a simple CASE function to calculate a column and as a criterionin the WHERE clause(C) Use a scalar UDF to calculate a column(D) Use a scalar UDF to calculate a column and as a criterion in theWHERE clause(E) Use a scalar CLR UDF to calculate a column(F) Use a scalar CLR UDF to calculate a column and as a criterion inthe WHERE clauseA sample of the results is as follows (time in milliseconds):(295310 row(s) affected)A: 1563(150003 row(s) affected)B: 906(295310 row(s) affected)C: 2703(150003 row(s) affected)D: 2533(295310 row(s) affected)E: 2060(150003 row(s) affected)F: 2190The scalar CLR UDF function was significantly faster than the classicscalar UDF, even for this very simple function. Perhaps a more complexfunction would have shown even a greater difference. Based on this, Imust conclude that Erland was right. Of course, it's still faster tostick with basic built-in functions like CASE.In another test, I decided to run some queries to compare built-inaggregates vs. a couple of simple CLR aggregates as follows:(G) Calculate averages by group using the built-in AVG aggregate(H) Calculate averages by group using a CLR aggregate that similatesthe built-in AVG aggregate(I) Calculate a "trimmed" average by group (average excluding highestand lowest values) using built-in aggregates(J) Calculate a "trimmed" average by group using a CLR aggregatespecially designed for this purposeA sample of the results is as follows (time in milliseconds):(59 row(s) affected)G: 313(59 row(s) affected)H: 890(59 row(s) affected)I: 216(59 row(s) affected)J: 846It seems that the CLR aggregates came with a significant performancepenalty over the built-in aggregates. Perhaps they would pay off if Iwere attempting a very complex type of aggregation. However, at thispoint I'm going to shy away from using these unless I can't find a wayto do the calculation with standard SQL.In a way, I'm happy that basic SQL still seems to be the fastest way toget things done. With the addition of the new CLR functionality, Isuspect that MS may be giving us developers enough rope to comfortablyhang ourselves if we're not careful.Bill E.Hollywood, FL------------------------------------------------------------------------- table TestAssignment, about 300,000 rowsCREATE TABLE [dbo].[TestAssignment]([TestAssignmentID] [int] NOT NULL,[ProductID] [int] NULL,[PercentPassed] [int] NULL,CONSTRAINT [PK_TestAssignment] PRIMARY KEY CLUSTERED([TestAssignmentID] ASC)--Scalar UDF in SQLCREATE FUNCTION [dbo].[fnIsEven](@intValue int)RETURNS bitASBEGINDeclare @bitReturnValue bitIf @intValue % 2 = 0Set @bitReturnValue=1ElseSet @bitReturnValue=0RETURN @bitReturnValueEND--Scalar CLR UDF/*using System;using System.Data;using System.Data.SqlClient;using System.Data.SqlTypes;using Microsoft.SqlServer.Server;public partial class UserDefinedFunctions{[Microsoft.SqlServer.Server.SqlFunction(IsDetermini stic=true,IsPrecise=true)]public static SqlBoolean IsEven(SqlInt32 value){if(value % 2 == 0){return true;}else{return false;}}};*/--Test #1--Scenario A - Query with calculated column--SELECT TestAssignmentID,CASE WHEN TestAssignmentID % 2=0 THEN 1 ELSE 0 END ASCalcColumnFROM TestAssignment--Scenario B - Query with calculated column as criterion--SELECT TestAssignmentID,CASE WHEN TestAssignmentID % 2=0 THEN 1 ELSE 0 END ASCalcColumnFROM TestAssignmentWHERE CASE WHEN TestAssignmentID % 2=0 THEN 1 ELSE 0 END=1--Scenario C - Query using scalar UDF--SELECT TestAssignmentID,dbo.fnIsEven(TestAssignmentID) AS CalcColumnFROM TestAssignment--Scenario D - Query using scalar UDF as crierion--SELECT TestAssignmentID,dbo.fnIsEven(TestAssignmentID) AS CalcColumnFROM TestAssignmentWHERE dbo.fnIsEven(TestAssignmentID)=1--Scenario E - Query using CLR scalar UDF--SELECT TestAssignmentID,dbo.fnIsEven_CLR(TestAssignmentID) AS CalcColumnFROM TestAssignment--Scenario F - Query using CLR scalar UDF as crierion--SELECT TestAssignmentID,dbo.fnIsEven_CLR(TestAssignmentID) AS CalcColumnFROM TestAssignmentWHERE dbo.fnIsEven(TestAssignmentID)=1--CLR Aggregate functions/*using System;using System.Data;using System.Data.SqlClient;using System.Data.SqlTypes;using Microsoft.SqlServer.Server;[Serializable][Microsoft.SqlServer.Server.SqlUserDefinedAggregate (Format.Native)]public struct Avg{public void Init(){this.numValues = 0;this.totalValue = 0;}public void Accumulate(SqlDouble Value){if (!Value.IsNull){this.numValues++;this.totalValue += Value;}}public void Merge(Avg Group){if (Group.numValues > 0){this.numValues += Group.numValues;this.totalValue += Group.totalValue;}}public SqlDouble Terminate(){if (numValues == 0){return SqlDouble.Null;}else{return (this.totalValue / this.numValues);}}// private accumulatorsprivate int numValues;private SqlDouble totalValue;}[Serializable][Microsoft.SqlServer.Server.SqlUserDefinedAggregate (Format.Native)]public struct TrimmedAvg{public void Init(){this.numValues = 0;this.totalValue = 0;this.minValue = SqlDouble.MaxValue;this.maxValue = SqlDouble.MinValue;}public void Accumulate(SqlDouble Value){if (!Value.IsNull){this.numValues++;this.totalValue += Value;if (Value < this.minValue)this.minValue = Value;if (Value > this.maxValue)this.maxValue = Value;}}public void Merge(TrimmedAvg Group){if (Group.numValues > 0){this.numValues += Group.numValues;this.totalValue += Group.totalValue;if (Group.minValue < this.minValue)this.minValue = Group.minValue;if (Group.maxValue > this.maxValue)this.maxValue = Group.maxValue;}}public SqlDouble Terminate(){if (this.numValues < 3)return SqlDouble.Null;else{this.numValues -= 2;this.totalValue -= this.minValue;this.totalValue -= this.maxValue;return (this.totalValue / this.numValues);}}// private accumulatorsprivate int numValues;private SqlDouble totalValue;private SqlDouble minValue;private SqlDouble maxValue;}*/--Test #2--Scenario G - Average Query using built-in aggregate--SELECT ProductID, Avg(Cast(PercentPassed AS float))FROM TestAssignmentGROUP BY ProductIDORDER BY ProductID--Scenario H - Average Query using CLR aggregate--SELECT ProductID, dbo.Avg_CLR(Cast(PercentPassed AS float)) AS AverageFROM TestAssignmentGROUP BY ProductIDORDER BY ProductID--Scenario I - Trimmed Average Query using built in aggregates/setoperations--SELECT A.ProductID,CaseWhen B.CountValues<3 Then NullElse Cast(A.Total-B.MaxValue-B.MinValue ASfloat)/Cast(B.CountValues-2 As float)End AS AverageFROM(SELECT ProductID, Sum(PercentPassed) AS TotalFROM TestAssignmentGROUP BY ProductID) ALEFT JOIN(SELECT ProductID,Max(PercentPassed) AS MaxValue,Min(PercentPassed) AS MinValue,Count(*) AS CountValuesFROM TestAssignmentWHERE PercentPassed Is Not NullGROUP BY ProductID) BON A.ProductID=B.ProductIDORDER BY A.ProductID--Scenario J - Trimmed Average Query using CLR aggregate--SELECT ProductID, dbo.TrimmedAvg_CLR(Cast(PercentPassed AS real)) ASAverageFROM TestAssignmentGROUP BY ProductIDORDER BY ProductID

Hi, I have a database field of type "money". But when I rerieve it to text box, it shows 5.0000, but I want only 5.00 to be shown. How do I format that? Any reply will be much appreciated. :)
Hi! I'm quite new to SQL Server. I need to set a float datatype to display something like 3.55. However, all values that are stored in the float column are truncated to 4 or some other single digit. How can this be prevented?
I am sure this is a newbie question as I am new to Microsoft SQL server but any help is greatly appreciated. I am populating a SQL database from an AS400. The decimal numbers from the AS400 are coming accross with extra decimals. (ie. 63.02 is coming accross as 63.0200001)
Is there a way to limit the number of decimals in a float or real field - or a SQL command I can put in a script to truncate each field to 2 decimal places after they are populated.
I have been trying to develop an automatic way of programmatically accessing datasources and performing some predefined(-supported) processing on them.
The question I would like to ask you people has to do with numeric fields. What exactly is precision? Is it the maximum length in digits of a field, or is there more to it? What about a "field's scale", what is it and how does it affect a field's value handling?
I have a table with a 'quantity' column (decimal 9:3) and a 'price' column (9:3). I have a third column 'amount' with a formula of (price * quantity). The formula gives the correct answer, but the precision is automatically set to 5. Is there any way to set the precision of the result to 2?
I am using ASP and SQL 2005 Express.I am inserting a timestamp from an ASP page using <%=now%into asmalldatetime field.

The only solution I found is use DataReader Source,
But if I use DataReader Source everything works fine , I mean I am able to see the records and convert it desired data type (using Data Convertion component).
My question is what component should I use as Destination, coz if I use OLEDB Desination I get a red cross on the components although I can map all the columns.....
Hi I am in the process of creating a new db in sql. In my users table I wish to set the UserIds as Integer datatype. It defualts on precision 4. Does this mean that when the column auto increments as its my primary key with a seed of one, my highest number allowed in the table would be row 9999. ???
Also if you where to store a phone number in your db, what column type would you give it. I have used varChar but its all numbers i want to store. Would this suffice.
We have a field which is decimal (9,2) and another which is decimal(9,3). Is there anyway to subtract the two and get a precision 3value without changing the first field to 9,3?For instance, retail value is 9,2, but our costs are at 9,3 due tobeing averaged. To calculate margin (retail-cost), we want that alsoto be 9,3, but a basic subtraction comes out 9,2. You can see wedon't want to increase retail to be 9,3 (that would look funny), andit seems wasteful to store retail twice (one 9,2 for users and one 9,3for margin calc)...is there any other way?
there is a column which type is float in a table, i want to set the precision of its value, for example if its value is 10.333888, i want to get its value as 10.33, how to complete it in a select Sql?
I receive patient demographic files from hospitals that are in several different formats. I have written translations for each format. I need to upload the files into our accounting software. I have the file layout to upload data and it looks like this.

In SQL Server I have not found a way to set precision on an int. I have to have the correct length, and data type (A for alfa which is left justified and N for numeric which is right justified) field for a succsessfull upload. Suggestions on what data types to use would be very helpful, and then suggestions on how to output the data in a text file described example above would be a life saver.
I am using SQL 2000 in a kind of electronic wallet way. Users out money onto an account and spend it on various services on a system. The cost of those services is deducted from the value in their wallet, and everybody's happy. However, some very strange things have been happening to my transactions; seemingly at random.
Some transactions (such as purchasing time on the Internet) are returning values such as 0.10000000000000001 instead of 0.1. This minute difference affects the user's wallet balance because the rouge digit is subtracted from their account. So instead of a balance of, say, 3.4 they have 3.39999999999999999.
"So what?", I hear you say. Well the problem comes when it's time to give them a refund. They walk over to a kiosk and the machine tells them they have 3.40 remaining in their account (it's nicely rounding up the value), but when they click Refund, it tells them they have insufficient funds to complete the refund! (Note: The refund amount is being compared with the wallet balance). If I go into the database via Query Analyzer it tells me their balance is 3.3999999etc, but in Enterprise Manager the value is 3.4. If try to manipulate the data in any way it is treated as 3.4. However, if I add 0.000000000000001 then QA reads the value as 3.4 and the customer can get their refund.
My questions is this. One, how the hell do I stop this from happening? I only need the two decimal places. Taking the value in a query and round it up/chopping off the remaining decimal points hasn't worked. It always picks up the value as 3.4 in a query. Two, why on Earth is this happening??? Has anyone experienced this problem before.
Thanks in advance to anyone that's read this far down.
I'm importing data from and oracle database to an SQL one through a SSIS package, I'm getting this error: "The output column "earned_hours" has a precision that is not valid. The precision must be between 1 and 38". the package runs but returns this column as NULL values
earned_hours is of type "NUMBER" in oracle (some of the values are decimals), I tried making it numeric(x,y),float or decimal(x,y), but I'm still getting the same results.
does anybody know why is this happening or have a solution for this error?
I'm running a transformation script that's taking decimal(18,10) data and trying to shoehorn it into a numeric(9,6). generally this works, as most of the data in the original table is not using anywhere near the precision it's capable of, but once in a while I run into one that does use it.
Is there any way to automagically reduce the precision so that i can cram the data into the destination table?
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...
The fields fltValorPendente e fltTotal are of this type. Field intSinal is an Integer.
I execute the following query: SELECT (intSinal * fltValorPendente) / fltTotal as Coef, cast((intSinal * fltValorPendente) as decimal(21,6)) / fltTotal as CoefCast into tmp FROM tbl Where fltTotal<>0
As a result, table tmp is created with the following structure: CREATE TABLE [dbo].[tmp]( [Coef] [decimal](38, 6) NULL, [CoefCast] [decimal](38, 17) NULL ) ON [PRIMARY]
How come both fields don't get the same precision?
