Casting Or Converting Smallint Datatype To Datetime
Sep 8, 2007
A SQL Server 2005 db has three date related-columns (MonthGiven,
DayGiven, YearGiven) each as smallint datatype. I would like to
create a DocDate column (datetime datatype) that combines the data from
the three existing date-related columns. I have tried casting and
simple concatentation without success.
ALTER TABLE Details ADD DocDate DateTime NULL
UPDATE Details SET DocDate = CAST(MonthGiven AS DateTime)+ '/' + CAST(DayGiven AS DateTime) + "/" Cast(YearGiven As DateTime)
I think I need to be doing a Conversion instead of casting but
have been unable to implement info I have found in the SQL Server
Developer Center in my situation.
I have a varchar column that inludes dates in the following fomat: 03032007? When I try to cast this to datetime, I keep getting "Arithmetic overflow error converting expression to data type datetime." error. Maybe someone has some ideas how to handle this?
I need to change the datatype of a very large table from smallint to int... What would be an ideal solution to get this done in least amount of time. May be I can try with ALTER but , I am not sure about the time it would take ...and the page splits etc..
For a SQL statement in an Alias column I am am combing severalcolumns.But I am having problems with one column as it is a smallint.I get this errorSyntax error converting the nvarchar value to a column of data typesmallintMy Sql statement "Select Stilngcol1 + stringcol2 + intcol1 + stringcol3 As NewColNamefrom Table1I was wondering is there anyway to format/convert the smallint tonvarchar, without changing the database.
I have a dbfield which holds a smallint value for the time eg. 1406 . I have to add this value to a datetime value in another field but need the result as a datetime value. The result would be time(int) + date(datetime) = datetime(datetime). I need this to compare the hours between delivery and dispatch. Thanks for your help P
Biz talk server executes every query twice, first with FMT only to get metadata.If metadata changed, it will produce error.Now, i have query like:
SELECT col1, col2, col3 INTO #tmp FROM dbo.myTable
How SQL decide the type of column in #tmp? Does it create column of the same type as it is in dbo.myTable or its decision is based on result?For example, col1 is varchar(20), but col1 in #tmp will be varchar(200) or even nVarChar.Col2 is INT, but result is for example low number(like, 1,2,3,) - is it possible that col2 in #temp table will be smallint or tinyint even if col2 in myTable is INT.If that is true one way to overcome that will be to explicitly CAST all columns to proper data type. Is there any performance impact of casting: CAST(col1 as VARCHAR(20)) if col1 is already varchar(20) in dbo.myTable?
"Failed insert into PONL_WELL. WELL_NO=" + (DT_WSTR,10)PROP_NO
PROP_NO comes from ms sql server , and the derived component datatype for this column is DT_WSTR.
The destination will be ms sql server, and i have a data conversion after the derived component to cast from DT_WSTR to DT_STR.
However, the derived component failed everytime giving me
Error: 0xC0049064 at Load Ponl_Well, Derived Column [1342]: An error occurred while attempting to perform a type cast.
Anyone know how i can eliminate the data conversion component and just do my string and column concatenation in the derived column and have it output as DT_STR?
I realize that the CASE statement doesn't like different datatypes as return values but if I want to format the "0" in the second WHEN condition below to "000", how do I do that? I have a "Region" that is "000" and would like it to show up that way at the very top of my report. I have the GROUP BY and ORDER BY to work fine, it just shows up as "0" and I can't change it. I realize it is being read as an int but am having trouble with the CAST and where to place it. Thanks again, you guys are great.

SELECT Region = CASE WHEN branch_num IN(48,53,78,173,186,198,208,212,257,286,287,317,35 3,398,440, 478,571,572,610,1069) THEN 44 WHEN branch_num IN(484,532,841,864,7001,7101,7102,7103,7104,9031) THEN 0 ELSE 999 END
select @Agg = Cast(cast(cast(Max(TotMatch) as decimal) / cast((Max(TotNoMatch) + Max(TotMatch)) as decimal)* 100 as int) as varchar) + '%' FROM #Rpt; select @Agg1= Cast(cast(cast(Max(TotNoMatch) as decimal) / cast((Max(TotNoMatch) + Max(TotMatch)) as decimal)* 100 as int) as varchar) + '%' FROM #Rpt;
Now what i am doing finding the percentage of total match and then finding the no mathc and percentage of both. but when i get the answr.
I have a field in a table that stores date of birth. The field's datatype is char(6) and looks like this: 091703 (mmddyy). I want to convert this value to a datetime datatype.
What is the syntax to convert char(6) to datetime?
HI,I have a table with IDENTITY column with the datatype as INTEGER. Nowthis table record count is almost reaching its limt. that is totalrecord count is almost near to 2^31-1. It will reach the limit with inanother one or two months.In order to avoid the arithmentic overflow error 8115, we would likechange the datatype from INT to BIGINT. we hope this will solve ourproblem.How do I approch this datatype conversion?. Since the data count ishuge, that leads to a long down time of database.we need better approach or solution for this problem?. kindly give mea better solution that will reduce the total downtime of the productiondatabase.?.Regards
I would like to cast (convert) data type decimal(24,4) to decimal(21,4). I could not do this using standard casting function CAST(@variable as decimal(21,4)) or CONVERT(decimal(21,4),@variable) because of the following error: "Arithmetic overflow error converting numeric to data type numeric." Is that because of possible loss of the value?
I need to convert a text field (which contains only numbers) into an int field. What would be the easiest way to do so. SQL 6.5. There are about 100, 000 rows in the db.
I am populating tables with Columns of fixed length (of a text format) from a different table with some Columns of Money ( DataType). It would not allow me to populate these Columns.
Does anybody know how could I calculate the new date(adding @c to @bor subtracting @b to @c), having for example a declaration like this:DECLARE @a CHAR(12)DECLARE @b DATETIMEDECLARE @c INTSET @b='3.04.04';SET @c=6and to calculate the number of days between two dates with this kindof declaration(@a-@b or @b - @a):DECLARE @a CHAR(12)DECLARE @b DATETIMEDECLARE @c INTSET @a='12.2.04';SET @b='3.04.04';Thanks in advance.
Hi there,I have a table named Action. This table has a column InPrice with datatypenvarchar(12). I want to change its datatype from nvarchar(12) to money. Ibrowsed through the values and removed any dots. Th column now has onlynumeric values (and commas for decimal values such as 105,8). When I try tochange the datatype from nvarchar to money, following mesage is displayed:ADO error: Cannot convert a char value to money. The char value hasincorrect syntax.How can I solve this problem? I cannot figure out which values are causingthis error.Thanks in advance,Burak
Hi, I need to take a value from a textbox and insert it into a field in my database which takes decimals. My problem, no matter what I try I cannot convert the value so that the database will accept it. This all happens when the submit button is hit on my webpage. Here is the cmdSubmit_click sub code:
Dim surveyNum As Decimal = Decimal.Parse(txtSurveyNum.Text, Globalization.NumberStyles.Number) myCmd.CommandText = "INSERT INTO survey(ID) VALUES('" & surveyNum & "')" myCmd.Parameters.Add("surveyNum", SqlDbType.Decimal) myCmd.Parameters("surveyNum").Value = System.Convert.ToDecimal(txtSurveyNum.Text)
I'm editing an SSIS package. The source column has datatype float and the data is stored like 1,2 instead of 1.2. To change this into a period instead of comma there is a derived column step in the ssis package. The expression in this derived column step to change this goes as:<o:p></o:p> (DT_STR ,32,1 252)(REPLACE((DT_STR,32,1252)SUBSCHAAL_SCORE,",","."))<o:p></o:p>
where SUBSCHAAL_SCORE is the name of the column. As you see the data is converted into a string. I need it to be converted into a numeric datatype (18,6) instead of string/varchar but it must also handle the first issue with changing the comma into a period. <o:p></o:p>
I'm using foxpro and I'm completely new to SQL. I'm trying to create a database into which I need to enter a time field. I've read around on the net that the only way to do this is using a datetime datatype but I can't find anywhere that explains the format I use to INSERT INTO my tables.
Anyone help?
*EDIT* I actually just want to enter the time and not the date and the time, I have read it is possible to do this using a convert but I'm happy enough to have the date and the time as I don't want to overcomplicate anything at this stage.
Hi, Can anyone please help me with the syntax for this query please. Error is "syntax error converting varchar value '/' to a column of datatype int" Query:

Are we allowed to do a LIKE datetime in SQL queries? The records data looks like so: 9/21/2000 10:30:40 AM But I want to see model requests by an entire day ala: Select * From ModelRequests Where RequestDateTime Like '9/21/2000%' But I do know get any records returned. What is the special way of dealing with the datetime datatype for these purposes?
Hello! Here's the puzzle I'm trying to solve. I have 2 columns (CreatedDate and StatusDate) in the table both of datetime datatype. When I run query select * from sale where Statusadate = "11/30/2001" it returns rows back.
When I do the same but for CreatedDate column select * from sale where CreatedDate="11/30/2001" it returns zero rows back even if there are CreatedDates = "11/30/2001".
I don't understand why it works for one column and doesn't work for another one.
The example of CreatedDate value is "2001-11-30 10:10:33.000"

hi everybody, i'm trying to calculate the 'SUM' of time spent in hrs. n min. How can i do this using SQL Server? What i mean is, i've a column 'TIME_SPENT' that has 'datetime' datatype. This column saves time spent for an activity in format 'hh:mm'. Suppose a user spends 45min for activity 'A' and say 1hr 25 min for activity 'B' then i want to calculate the 'SUM' of 'TIME_SPENT' for the user which should appear as 'Total time spent =2:10'
