SIMPLE Command To Convert String To Number? Not CAST Or CONVERT.
Aug 15, 2006
Dear Experts,
Ok, I hate to ask such a seemingly dumb question, but I've
already spent far too much time on this. More that I
would care to admit.
In Sql server, how do I simply change a character into a number??????
In Oracle, it is:
select to_number(20.55)
from dual
TO_NUMBER(20.55)
----------------
20.55
And we are on with our lives.
In sql server, using the Northwinds database:
SELECT
r.regionid,
STR(r.regionid,7,2) as a_string,
CONVERT(numeric, STR(r.regionid,7,2)) as a_number,
cast ( STR(r.regionid) as int ) as cast_to_number
FROM REGION R
1 1.0011
2 2.0022
3 3.0033
4 4.0044
SELECT
r.regionid,
STR(r.regionid,7,2) as a_string,
CONVERT(numeric, STR(r.regionid,7,2) ) as a_number,
cast (STR(r.regionid,7,2) as numeric ) as cast_to_number
FROM REGION R
1 1.0011
2 2.0022
3 3.0033
4 4.0044
Str converts from number to string in one motion.
Isn't there a simple function in Sql Server to convert
from string to number?
This is because a date of 04/16/2014 will show as 160416 in the first part of the field I need to parse it out of, thus becoming 04162014.
From there I then need to convert this "date" into a legitimate SQL datetime type, so that I can then run a DATEDIFF to compare it to when the record was actually entered, which is a separate field in the table, and already in datetime format.
When I use the below statement, I am getting the message that, "Conversion failed when converting date and/or time from character string."
I'm new to SQL and I've been trying this for a while now.
I have let's say a loop of numbers from one to ten. It appears like this:
1 2 3 4 5
What I want to do is to have it appear on one column like this: 12345, the problem is I can't seem to figure out if I need to only have one variable or I'm missing something else, I figured you need to convert them into a string character but I'm still unable to do it.
Hi, I have dates in "mmddyy" format coming from the sources and they are older dates of mid 80s like 082580 for instance.
When I cast it this way (DT_DBTIMESTAMP) Source_Date , It says ok but throws a runtime error.
When I hardcode a date in same format, (DT_DBTIMESTAMP) "082580" , It becomes red (an indication of syntax error) . Please note that we use double quotes in expressions in Derived Column Transformation; So an anticipation that using double quotes over single ones would be the syntax problem would be wrong.
Have the following in my SELECT statement, which I'm having issues with when I modify it to include a CAST or a CONVERT.
CONCAT(PER.[PERSON-REF],ROW_NUMBER() OVER (PARTITION BY PER.[PERSON-REF] ORDER BY TEN.[tenancy-ref])) AS 'ID'How do I convert or cast it to a varchar (20)?
We have a 3rd party application that connects to our SQL 2005 as a external database source.
Our external database has a 'datein' field that for some reason is stored as a varchar(50).
I can use cast to convert the field to datetime, but how would I then format to the yyyy-mm-dd format in the same select statement(using in view)?
I need to convert this field to a format of YYYY-MM-DD in order for the 3rd party application to search on it correctly. Below is an example of the data -- FieldName = DateIn DateType = Varchar(50) 2006-07-06 Sep 12 2007 11:16AM 2007-07-19 Oct 2 2007 12:24PM 2007-08-19 Oct 31 2007 8:00PM Sep 15 2007 9:25AM 2007-08-18 Oct 16 2007 7:01PM Oct 30 2007 11:15AM Aug 29 2007 8:54AM Aug 29 2007 8:38PM Aug 25 2007 2:33PM
Hi all, I have a VB 6.0 application that interacts with an MS Access backend. I am in the process of converting it so that it interacts with SQL Server 2000. The current applications uses Cint, CStr, etc. functions which are MS-Access specific, so I am now switching over to Convert (or Cast) function. The problem is that there are certain places wherein I first need to store the value of the resultant CAST/Convert function in a variable and then use that value in a SQL statement. However, I cant seem to figure out a way of storing the results from CAST/CONVERT functions in the VB 6.0 variable. All the examples on Internet show use of these functions directly in an SQL statement e.g. "Select CAST(title as Int) from xyz", etc. Can anybody tell me how can i get the values to be stored in the variable? I am really stuck here and cant seem to progress.
I have a table with all varchar data for all different fields for money and int etc. I want to do a calcuation in one field with the rule as below:
UPDATE [dbo].[tblPayments] SET [PreInjuryWage]= CASE WHEN [WeekNo]<14 THEN ([MaxWorkCover]+ [WeeklyEarnings] )/0.95 ELSE ([MaxWorkCover] + 0.80 * [WeeklyEarnings] ) /0.80 END
I tried this command after many other ways of tries
UPDATE [dbo].[tblPayments1] SET [PreInjuryWage]= CASE WHEN [WeekNo]<14 THEN CAST ( (cast([MaxWorkCover] as money )+ cast([WeeklyEarnings] as money ))/0.95 AS Varchar(10) ) ELSE CAST ( (convert(money, [MaxWorkCover] + (0.80 * convert(money, [WeeklyEarnings] )) )/0.80 ) as varchar(10)) END
The structure of the table ( its a legacy table from 2000 i beleive)
CREATE TABLE [dbo].[tblPayments]( [PaymentID] [int] IDENTITY(1,1) NOT NULL, [ClaimID] [int] NOT NULL, [WeekNo] [smallint] NULL,
[code]....
Arithmetic overflow error converting numeric to data type varchar.
select @Agg1= Cast(cast(cast(cast(Max(TotMatch) as decimal) / cast((Max(TotNoMatch) + Max(TotMatch)) as decimal)* 100 as int) - 100 as int) as varchar) + '%' FROM #Rpt;
if i try this it is giving me answer in -2% how i can remove the - sign
also if I try the same statement in different way. well I am going to post in other post.
Hi people, I am trying to use Aggregate function like count or average on a column which has a datatype Varchar. In order to use avg or count on it , I am doing a cast on it. If somebody has use Cast/Convert with aggregate function please help me Thanks Jesal
How do I use the CAST or CONVERT function in the code below, I require a third column (named Diff) which Minus the StartTime from the EndTime and the result is outputted in the third column (named Diff).
Calculation: @Diff = (@EndTime - @StartTime)
I still want the variables (@StartTime and @EndTime) to remain as nvarchar.
The code:
DECLARE @StartTime nvarchar(10) = '12:10'; DECLARE @EndTime nvarchar(10) = '12:30'; DECLARE @Diff time(1) = '00:00'; SELECT @StartTime AS '@StartTime', @EndTime AS '@EndTimes', @Diff AS '@Diff';
I have created a SQL Stored Procedure that uses a Case statement todetermine the Order By. For one of the Case statements I am trying toturn a Char field into Datetime in for the Order By, however I can notget it to work. Can someone please take a look and my code below andtell me what I am doing wrong. Thank you.ORDER BYCASE WHEN @SortBy = 'dttm_stamp' THEN dttm_stamp End,CASE WHEN @SortBy = 'Event_Date1' THEN CAST(CONVERT(char(10),Event_Date1,101) as datetime) End,CASE WHEN @SortBy = 'FullName' THEN Emp_lastname + ', ' +Emp_firstname End,CASE WHEN @SortBy = 'FullName Desc' THEN Emp_lastname + ', ' +Emp_firstname End DESC,CASE WHEN @SortBy = 'Emp_SSN' THEN Emp_SSN End
I have been having some trouble trying to get the date format YYYYMMDD 00:00:00.00 to convert to MM/DD/YYYY. I am using SQL 2005 and Reporting Services. I attempted several variations to solve this problem as outlined below, with the final working conclusion at the end. I am not saying that this is the BEST or the ONLY way to achieve the solution, but it worked for me.
Code Block --------------------------------------------------------------------------------------- SELECT DATE_TIME AS DATE1 FROM TRANSLOG --returns value of 20071027 02:26:24.06 --------------------------------------------------------------------------------------- SELECT CAST(DATE_TIME AS SMALLDATETIME) AS DATE1 FROM TRANSLOG --returns value of 2007-10-27 02:26:00 --------------------------------------------------------------------------------------- SELECT LEFT(CAST(DATE_TIME AS SMALLDATETIME),11) AS DATE1 FROM TRANSLOG --returns value of Oct 27 2007 --------------------------------------------------------------------------------------- SELECT CAST(SUBSTRING(DATE_TIME,0,9) AS SMALLDATETIME) AS DATE1 FROM TRANSLOG --returns value of 2007-10-27 00:00:00 --------------------------------------------------------------------------------------- SELECT CONVERT(VARCHAR(10), DATE_TIME, 103) FROM TRANSLOG --although this works with GETDATE(), it does not work with the DATE_TIME field --------------------------------------------------------------------------------------- SELECT CONVERT(VARCHAR(10), CAST(DATE_TIME AS SMALLDATETIME), 101) AS DATE1 FROM TRANSLOG --THIS WORKS!!!

Hi I have a varchar(8000) and currently XML files are stored in varchar(8000).Some times when i am doing manuplactions in my varchar column i am getting with special characters error. so now i want to keep my column varchar(MAX) and when i am doing calculations i will convert my varchar datatype to xml datatype. By doing this i hope there wont be any special character problems. When i am doing calculations with the wellformed xml i am getting error for both convert and cast methods as below I am trying to do convert(xml,MyVarcharColumn) Implicit conversion from data type xml to nvarchar is not allowed. Use the CONVERT function to run this query. Also i tried with casting and getting same problme. is there any way to convert
All of my currency columns are only storing 2 decimal places when I insert into the database but when I pull out the data with a SELECT statement, I always get 4 decimal places instead of the 2 that were inserted. For example: Database Price SELECT statement Price 100.56 100.5600 I have tried to use the CAST and/or CONVERT commands but I cannot get the output to come out as 100.56. Has anyone had a similar problem? Thanks
Using OnSelected on the SqlDataSource----here is my currect code:private void On_Load(Object sender, SqlDataSourceCommandEventArgs e){if (e.Command.Parameters["@DueDate"].Value = "NULL"){e.Command.Parameters["@DueDate"].Value = "0000-00-00 00:00:00.000";}} I am trying to change the value from NULL(in a datetime field) to "0000-00-00 00:00:00.000" for use on the page.Any ideas, suggestions, or thoughts would be greatly appreciated! ,Gary"we truly fail, only when we quit."
Never did a convert, I been looking for samples but I don't quite get it. I get this error message in my vb.net app, Taking a number value from a textbox, adding it to a table, with a money field.
"Implicit conversion from data type money to nvarchar is not allowed. Use the convert function to run this query"
Here is the SP it's pulling,
CREATE PROCEDURE dbo.AddWg (@UserID NvarChar(50), @Credits Money) AS IF EXISTS (SELECT 1 FROM Bankroll WHERE UserID=@UserID) begin Update BankRoll Set Credits = Credits + CAST(@Credits as money) where userID = @userID return -1 end ELSE begin Insert Bankroll (Credits, UserID) Values (@Credits, @UserID) RETURN @@IDENTITY
end GO
The store procedure worked when Credits was nvarchar, but then I switched it to money, and now this. How would I use the CONVERT to fix this?
I have a table called class_time. and the column name is start_time.datatype is datetime.id start_time21900-01-01 15:00:00.00041900-01-01 17:12:00.000i want to the convert the start_time column into a format that onlyhas the hour and minutes plus AM/PM ( for example, 3:00 pm, 5:12pm)id start_time new format21900-01-01 15:00:00.000 3:00 pmis there any simple one step way to do that?(the only way i know is to use the following query, then do a substringwhere the space is. but that's too complicated)select CONVERT(CHAR(20), start_time, 22) from class_timeThank you in advance for your time.
Hi!I' m sitting here now for days and I still get no conclusion on myproblem. I have an MS ACCESS .mdb File and I would like to export itwith dtswiz.exe (from MS SQL Utility Tools) via command line. (If youknow other tools which are able to do that via command line I wouldappreciate any suggestion)I tried to find another Provider Parameter (like MSDASQL) for Accessbut somehow it seems to me that Microsoft only got one. I' m also ableto address a Server which appears in the GUI but I don t need one formy ACCess DB (I only tried, if the command parameters have any effecton the converter).I would be glad if someone could help me on this.Thank youKlaus Baumgarten
I want to combine two of my fields somewhat like when you combine to char fields and concatenate them. But these two fields are int. How do i do that? Here's my query right now:
Code Block SELECT AutoID, CONVERT(Varchar(Mars_Calender_Year )+ CONVERT(Varchar(Mars_Calender_Period_Code) as MarsId FROM NavisionReplication.dbo.Tbl_Mars_Calender ORDER BY Mars_Calender_Year DESC
