Hi,
I'm inserting a datetime values into sql server 2000 from c#
SQL server table details
Table nameate_test
columnname datatype
No int
date_t DateTime
C# coding
SqlConnection connectionToDatabase = new SqlConnection("Data Source=.\SQLEXPRESS;Initial Catalog=testdb;Integrated Security=SSPI");
connectionToDatabase.Open();
DataTable dt1 = new DataTable();
dt1.Columns.Add("no",typeof(System.Int16));
dt1.Columns.Add("date_t", typeof(System.DateTime));
DataRow dr = dt1.NewRow();
dr["no"] = 1;
dr["date_t"] = DateTime.Now;
dt1.Rows.Add(dr);
for(int i=0;i<dt1.Rows.Count;i++)
{
string str=dt1.Rows["no"].ToString();
DateTime dt=(DateTime)dt1.Rows["date_t"];
string insertQuery = "insert into date_test values(" + str + ",'" + dt + "')";
SqlCommand cmd = new SqlCommand(insertQuery, connectionToDatabase);
cmd.ExecuteNonQuery();
MessageBox.Show("saved");
}
When I run the above code, data is inserted into the table
The value in the date_t column is 2007-07-09 22:10:11 000.The milliseconds value is always 000 only.I need the millisecond values also in date_t column.
Is there any conversion needed for millisecond values?
thanks,
Mani
hi,
it is my first post on this forum, please be patient if i miss any important bit of information.
i am transporting data from a legacy system into mssql 2k5 using SSIS.
among those column of a dataset there are 13 columns, all necessary for operational reasons, that i need to ensure data consistance.
i believe i could do this check using the lookup data flow item, but surely there must be a way to do it in a more streamlined fashion.
since column names contain numbers to distinguish the version, eg; col01, col02, col03 .. col13.
i thought i could include the lookup within a loop and use a couple of variables to do this trick, but since i have not done it before i am asking for some sort of guidance from a guru among you folks.
please let me know if further clarification is necessary.
regards,
nicolas
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.
We have a really annoying job here that relies on a particular file to be created before several imports run. An old file may already exist, but if it isn't recent, we don't want the import to run. This job can't delete it, since other jobs use that file. What we'd like to do is to be able to check the creation date of the file, and if it is after a certain time of day, run the import, else, delete the file. I know of xp_fileexists. Is there anything similar in SQL that can return file information or am I stuck parsing the output from xp_cmdshell 'dir F:ftpcoreinputready.txt'? Any help or hints are appreciated. Let me know if you need more info. Thanks. -D.

Say I've got two time intervals represented two rows of Start Date and End Date.
Can anyone think of a way to express a query in which I can work out how many days the time intervals overlap each otheR?
Like for example if the first interval is pretty 1/5/08 and 13/5/08
and the second one is 5/5/08 and 15/5/08, then i guess the answer should be 8 days.
How can I calculate a DateTime column by merging values from a Date column and only the time part of a DateTime column?
View 5 Replies View RelatedI am relatively new to SQL and as a project I have been asked to create the SQL for a simple database to record train details. I want to implement a check constraint which will prevent data from being inserted into a table if the weight of the train is more than the maximum towing weight of the locomotive. FOr instance, I need to add the unladen weight and maximum capacity of each wagon (located in the wagon type table) and compare it against the locomotive maximum pulling weight (the locomotive class table). I have the following SQL but it will not work:
check((select SUM(fwt.unladen_weight+fwt.maximum_payload) from
hauls as h,freight_wagon as fw,freight_wagon_type as fwt,train as t where
h.freight_wagon_serial_number = fw.freight_wagon_serial_number and
fw.freight_wagon_type = fwt.freight_wagon_type and
h.train_number = t.train_number) <
(select lc.maximum_towing_weight from locomotive_class as lc,locomotive as l,train as t where
lc.locomotive_class = l.locomotive_class and l.locomotive_serial_number = t.locomotive_serial_number))
The hauls table is where the constraint has been placed and is the intermediary table between train and freight wagon.
I may not have explained this very well; but in short, i need to compare the sum of two values in one table against a values located in another table...At present I keep getting a message telling me the sub query cannot return more than one row.
There has been a number of topics recently regarding calculations of overlapping times. Here is one approach to reach this with a UDF.CREATE FUNCTION dbo.fnTimeOverlap
(
@FromTime DATETIME,
@ToTime DATETIME,
@Login DATETIME,
@Logout DATETIME
)
RETURNS INT
AS
BEGIN
DECLARE@Temp DATETIME,
@Seconds INT
IF @FromTime > @ToTime
SELECT@Temp = @FromTime,
@FromTime = @ToTime,
@ToTime = @Temp
IF @Login > @Logout
SELECT@Temp = @Login,
@Login = @Logout,
@Logout = @Temp
SELECT@Seconds = CASE
WHEN @FromTime <= @Login AND @Login <= @ToTime AND @ToTime <= @Logout THEN DATEDIFF(second, @Login, @ToTime)
WHEN @FromTime <= @Login AND @Logout <= @ToTime THEN DATEDIFF(second, @Login, @Logout)
WHEN @Login <= @FromTime AND @ToTime <= @Logout THEN DATEDIFF(second, @FromTime, @ToTime)
WHEN @Login <= @FromTime AND @FromTime <= @Logout AND @Logout <= @ToTime THEN DATEDIFF(second, @FromTime, @Logout)
END
RETURN@Seconds

I am writing report to display some IIS site activity, part of the requirement is to produce a trend for user activity for each week of the year.
I have written a stored procedure that uses datepart to split year, month and year week number into separate columns. However the problem I am having is that when a week is split over 2 months I end up with the two entries for the same week but across two months which also splits the count of activity into two rows. So when I produce a line chart in SSRS I end up with a dip due to the week total being split.
An example would be week number 14 of this year is split over two months, I think I need to add same week number activity counts together but not sure how to handle this in the stored procedure.
Just want to check if my query is the standard way to check if date ranges overlap in a price table as I need to check any that overlap as I can't have two prices on one day.
For example if in a table there was:
Product TROUSER Colour BLUE
Start Date 01-NOV-13 End Date 20-NOV-13 Price £20.00
Start Date 10-NOV-13 End Date 12-NOV-13 Price £18.00
Start Date 21-NOV-13 End Date 25-NOV-13 Price £15.00
The top two overlap.I'm doing this which is giving me nothing returned which I'm hoping means I have no overlapping date ranges:
SELECT a.[PriceList]
,a.[ProductID]
,a.[Colour]
,a.[Start Date]
,a.[End Date]
,a.[Product Price]
[code]....
How can I check on NULL values in a Select statement?
SELECT ID FROM TabelWHERE somecolumn <> NULL??
I have a column bar chart which displays values for each month. As per the requirement, I am displaying the column values by selecting "Show labels" options. I see few values overlap on the column bars.

I have set up a trigger that fires when an update has been performed on a specific table. The trigger checks to see if specific columns have been updated. If they have, then the trigger code is executed. This part works fine.
I am now trying to find a way to check if null values exist in either one of two field from the same table. If either field contains a null value, then I don't want the trigger code to be executed.
How can I check for null values and skip a block of code within my Transact Sql trigger.

Hey all,
I was wondering what the best method of checking on page_load if a datasource control is pulling back nothing from a database. I want to display a message explaining that there is no data to be displayed. How would I go about doing that? I have tried searching google and whatnot but didn't find anything really helpful.
Here is the current code for the data source control.
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|EventInsider.mdf;Integrated Security=True;User Instance=True"
ProviderName="System.Data.SqlClient" SelectCommand="SELECT Events_Groups.GroupName, Events_Groups.GroupID FROM Events_GroupMembership INNER JOIN Events_Groups ON Events_GroupMembership.GroupID = Events_Groups.GroupID WHERE (Events_GroupMembership.UserID = @UserID)">
<SelectParameters>
<asp:SessionParameter Name="UserID" SessionField="UserID" />
</SelectParameters>
</asp:SqlDataSource>
But I have no idea what the code behind would be to check it on page_load. If there is no way to particularly do this, do you have to do it per control? Like dropdownbox's or gridviews? I am just confused on how to check to make sure there is data to be displayed.
Thanks,
Chris
say i have a table, and in it are two columns, column1 and column2 and i do the following query:
SELECT column1, column2 FROM table WHERE column2 = '12345'
i want to check if column1 has all the same values, so in the first case, no
column1 column2
------- --------
4 12345
9 12345
5 12345
column1 column2
------- --------
9 12345
9 12345
9 12345
in the 2nd case, column1 contains all the same values, so yes
is there anyway i can check this? i would be doing this in a trigger.. say when a new row is inserted, the value of column1 is inserted, but col 2 is null.. so when they try to fill in the value for col2 of that row, the trigger checks to see if the value they put for col 2 is already in the table.. if it isn't, then everything is ok. but if it is already in teh table, then it checks col1 to see if all the values of col1 are the same
i hope this makes sense
thanks
I'm pretty new to sql server and now I need to create a script that:

Hi All,
I have a table Saleshistory with 89481412 records. I have a field Sales of nvarchar type, all the records in this field are numeric, and the records are with 2 decimal places. I expect all the records to be ending at .00 (for example 5.00,345.00,25.00), but I want to verify if something is for example 5.6 etc.
So in short I want to check if any Salesrecords have more than zero values in the decimal. How can I check this.
Please help.
Thanks,

Hi all,
I wanted to check the previous and next record values.
For example:
sKey NextKey PreviousKey
1 2 Null
2 8 1
8 5 2
5 null 8
I wanted to check the value of NextKey of Prev record and Skey of Next record.
Any idea?

Helen
Hi all,
I wanted to check the previous and next record values.
For example:
sKey NextKey PreviousKey
1 2 Null
2 8 1
8 5 2
5 null 8
Ex : In the first record of the table, the NextKey is pointing to 2.
So the next record of Skey will be 2. The Next Key for this record is 8. Like wise the next record of this should have the Skey as 8.
Now I need to check whether the NextKey and SKey are correct for all rows.
For that I need to check the previous record of "Next key" and next record of "Skey".
Any idea?
Regards
Helen

Is it possible to write a sql statement to skip aplpha numeric values? I got a field containing these values; 20, 70, 150, 140, 100, KORT, 90, 180, 160. And I'm trying to check if any value is bigger than 175 (@Limit), but I want to skip the value 'KORT'. So is it possible to check if a value is numeric or not? ISNULL( CONVERT(int, ProductVariant.Size), 0) > @Limit Regards, Sigurd

I have created dynamic sql to declare variables based on columns from the table and i set values to those variable now here is the issue . i want to check the variable values how do i do that dynamically
drop table test
create table test

id varchar(10) not null,
col1 varchar(10) ,
col2 varchar(10)
[Code] .....
Now my next step is verify if the variable is blank or not how do i do that ?
How do i verify all of the columns one after the other .
I am after the statement like this dynamically
-- IF NOT (@col1 = '') THEN set @SQL = @SQL + '[col1] = ' + @col1 + ' '
--IF NOT (@col2 = '') THEN set @SQL = @SQL + '[col2] = ' + @col2 + ' '
I need to check if the columns are blank or not dynamically as i do not want to hard code the column names there.

AS
declare @currency as char(50)
declare @country as char(50)
declare cur cursor for SELECT currency, country

fetch cur into @currency, @country
WHILE @@FETCH_STATUS = 0
BEGIN
if not exists(select * from listinfoid where listname = 'currency' and listid = @currency)
begin
set @currency = (cast(@currency as varchar (3)) + ' is not a valid currency')
CLOSE cur
DEALLOCATE cur
RAISERROR (@currency,16,-1) with log
return
end

guys this is kind of a biggie for me.
i've only used sql server to compare the Date Portion of date(s), not the whole string (mm/dd/yyyy hh:mi).
i have a table called Time_Check which has two fields with timestamps,
"TimeLastRun & TimeNextRun". i was trying to compare the Current TimeStamp that i pass from a vb.net form to a stored procedure and compare that DateTime to the TimeNextRun. I'd like to then Update the two Time Columns if rows are found. Should i maybe be using the DateDif Func if i know ahead of time how much time should be elapsed(say five minutes)?
Any Code help is appreciated
Create Procedure dbo.My_Time_Check
@myDate smalldatetime
as
select alertnumber,alertname,TimeLastRun,TimeNextRun
from time_check
where timeNextRun >= @myDate
--would like to update these two columns if rows are found

I know how to check for a sinle vlaue but how do I chekc to see if multiple values exist. I need to check for certain email addresses from a list that I have.
Let us say I ahve 3 email addresses, I want to check for all of them in a table and for eevery email address that is present I want to print something like "You email address is XXX" and if one of those 3 is not found my results should look like
"You email address is XXX"
YYYYY not found
"You email address is ZZZZ"
I'm attaching some TSQL that I tried on [AdventureWorks2012].[Person].[EmailAddress]
/****** Select ALL if where an email address is present in the list ******/
SELECT EmailAddressID,EmailAddress
FROM [AdventureWorks2012].[Person].[EmailAddress]
WHERE EmailAddress IN
(
'ken0@adventure-works.com', --1
'terri0@adventure-works.com', --2
[Code] ....
-- Test to see if a single email address is present
IF EXISTS
(
SELECT EmailAddress FROM [AdventureWorks2012].[Person].[EmailAddress]
WHERE EmailAddress IN ('25rob0@adventure-works.com')
)
BEGIN
SELECT 'Email address is presnt'
[Code] ....
When I check multiples using EXISTS it works as per its design and says YES even if a single item is present.
I have the following objective:
1. I want to check a column to see if there are values (to Eliminate dups)
2. Once checked the values in a column, if not found insert the new value
Here is my code for this:
ALTER TRIGGER DUPLICATES ON AMGR_User_Fields_Tbl
-- When inserting or updating
AFTER INSERT, UPDATE AS
-- Declare the variables
DECLARE @AN varchar(200)
