SQlfunction To Check Date
Sep 10, 2007
Hi
I need to have a second copy of our databse on another server as backup if something will happen to the first one.
I couldn´t get the sql replication or database mirror to work ( I think the problem i that both servers are running in a workgroup an dnot in a domaine) and now I try to solved my problem with an automatic restore of the full backup (a new full backup is running every night) but now I need a function to check if todays date is the same as a part of the backupfilename and is it possible to do that as a step in the sqlagentjob i have create?
Thanks for any help how I can do that

I am trying to use System.IO.Compression to compress/decompress the buffer. I have the data in byte format in sql server and I need to create an CLR user defined function. I have everything running except that for some of the files, the compressed size is larger than the actual file size. I tried to use both Deflate and GZip compression types. Did anyone face the similar situation. Thanks in advance for your help.

I have built a Table Valued SqlFunction which streams out filtered results from a table. The way that I have implemented this is by using a custom class which implements the IEnumerator interface.
The class internally stores a SqlDataReader and a SqlConnection as private member variables. The Class initializer (ie: the New function) creates a SqlCommand which is executed with ExecuteReader into the SqlDataReader and returns.
The IEnumerator.MoveNext method loops through the SqlDataReader until it finds a result which matches the heuristic filter, and the IEnumerator.Current method returns the current result from the SqlDataReader.
Unfortunately as soon as the initializer returns the SqlDataReader is automatically closed, and I can't figure out why. I've debugged through this and at the end of the Initializer the SqlDataReader is definately open, and as soon as first call to MoveNext is run it is closed.
Can anyone offer any suggestions on how I can fix this.
In the interim i've had to load all of the filtered results into a temporary ArrayList in the Initializer, which defeats the purpose of streaming out the results.

There is a SqlFunction in my SQL Server Project:
[Microsoft.SqlServer.Server.SqlFunction(DataAccess=DataAccessKind.Read)]
public static SqlBoolean GetRelation(SqlGuid ID)
{
using (SqlConnection conn = new SqlConnection("context connection=true"))
{
conn.Open();
SqlCommand cmd = new SqlCommand("SELECT * FROM MemberRelation WHERE ID='" + ID + "'", conn);
//SqlCommand cmd = new SqlCommand("EXEC GetMemberRelation '" + ID + "'", conn);
/*SqlCommand cmd = new SqlCommand("GetMemberRelation", conn);
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.Add(new SqlParameter("@ID", SqlDbType.UniqueIdentifier));
cmd.Parameters["@ID"].Value = ID;*/
using (SqlDataReader sdr = cmd.ExecuteReader())
{
sdr.Read();
//...
sdr.Close();
}
conn.Close();
}
}
When I try to call a stored procedure by using one of the two marked code segments instead of concatenating string in GetRelation, I can deploy the project to my SQL server without problem. But when I call GetRelation from Query Analyzer, I get an error: "Invalid use of side-effecting or time-dependent operator in 'SET ON/OFF' within a function."
What does the error message mean? How could I correct it? Thanks for answering.

Hi, ppleI am trying to check dates. I tried something like this but it doesn't work.
Dim strarray As Array
Try
Dim my As New Database
my.OpenConn()
Dim d As SqlDataReader
Dim dr2 As SqlDataReader
d = my.ExecuteQuery("Select lastLogin, ID from Student")
While d.Read
Dim ld As DateTime = d("lastLogin")
If ld > FormatDateTime(Now) Then
strarray() = strarray() + d("ID")
End If
End While
d.Close()
dr2 = my.ExecuteQuery("Insert into Audit (auditID, ID, auditMsg, updatedDate) values ('200','20','" & strarray() & "','" & FormatDateTime(Now) & "');")
dr2.Close()
my.CloseConn()
Catch x As Exception
Debug.WriteLine(x)
End Try

Hey all,
I've been ehre off and on when I've needed help. And I know someone answered my question last time with the exact info I needed. But I seem to have lost the query I saved.
I pretty much need a query that can filter a field I have adn pull up any records that are not in in date format. My current field is text and I'm trying to convert it over to DateTime but am getting stuck. Seems at least one of the records does not have a date format.
Thank you all.

I would like to check if the incoming date is valid date and i would also like to check if the date exists in my database.
i am transfering data from a flat file so all the data is string data.
How would i assign the datatype to the incoming columns as they exists in the sql table.Because it would better when i try to compare my incoming columns with the once in my database.
Here when i have a lookup transform and try to map one of my columns with string datatype to a column in my sql table of datatype date time i get a datatype mismatch error. How do i need to check if its date time...and how can i check if the incoming date is valid date.
please let me know

First I want to thank everyone that has given help to me and everyone else with the issues involving migrating to 2005... Thanks alot..
Now for the problem. I am looking for (an not finding anything of help) to check the date of a file on an ftp server. A file always exists but once a month the day changes. I would just download the file and check it locally but the files are several hundred megs in size so that would be inefficient.
So is there anyway to do that??
On another note, can anyone point me to a good resource for learning the scripting language that SSIS uses??

Hi guys,I have written a stored procedure to check for date range, say if the user enters a value for 'city-from' , 'city-to', 'start-date' and end-date, this stored procedure should verify these 2 dates against the dates stored in the database. If these 2 dates had already existed for the cities that they input, the stored procedure should return 1 for the PIsExists parameter. Below's how I constructed the queries: 1 ALTER PROCEDURE dbo.DateCheck
2 @PID INTEGER = -1 OUTPUT,
3 @PCityFrom Char(3) = '',
4 @PCityTo Char(3) = '',
5 @PDateFrom DATETIME = '31 Dec 9999',
6 @PDateTo DATETIME = '31 Dec 9999',
7 @PIsExists BIT = 1 OUTPUT
8 AS
9
10 CREATE TABLE #TmpControlRequst
11 (
12 IDINTEGER,
13 IsExistsCHAR(1)
14 )
15 /*###Pseudo
16 1. Check the Date From and Date To
17 -- select all the value equal to parameter cityFrom and cityTo
18 -- insert the selection records into tmp table
19 --*/
20 INSERT INTO #TmpControlRequst
21 (ID, IsExists)
22 SELECT ID,
23 IsExists = CASE WHEN DateFrom <> '31 Dec 9999' AND DateTo <> '31 Dec 9999'
24 AND @PDateFrom <= DateFrom AND @PDateFrom <= DateTo
25 AND @PDateTo >= DateFrom AND @PDateTo <= DateTo THEN 1
26 WHEN DateFrom <> '31 Dec 9999' AND DateTo <> '31 Dec 9999'
27 AND @PDateFrom >= DateFrom AND @PDateFrom <= DateTo
28 AND @PDateTo >= DateFrom AND @PDateTo <= DateTo THEN 1
29 WHEN DateFrom <> '31 Dec 9999' AND DateTo <> '31 Dec 9999'
30 AND @PDateFrom >= DateFrom AND @PDateFrom <= DateTo
31 AND @PDateTo >= DateFrom AND @PDateTo >= DateTo THEN 1
32 WHEN DateFrom <> '31 Dec 9999' AND DateTo <> '31 Dec 9999'
33 AND @PDateFrom <= DateFrom AND @PDateFrom <= DateTo
34 AND @PDateTo >= DateFrom AND @PDateTo >= DateTo THEN 1
35 ELSE 0 END
36 FROM RequestTable
37 WHERE ID <> @PID
38 AND CityFrom = @PCityFrom
39 AND CityTo = @PCityTo
40
41 --======== FINAL RESULT
42 -- For tmp table:-
43 -- isExists = 1 ==> date lapse
44 -- isExists = 0 ==> date ok
45 -- if count for (isExists = 1) in tmp table is > 0 then return 1 and data not allow for posting
46 SELECT @PIsExists = CASE WHEN COUNT(*) > 0 THEN 1
47 ELSE 0 END
48 FROM #TmpControlRequst
49 WHEREIsExists = 1
50
51 SELECT @PIsExists
52 --=========
53
54 DROP TABLE #TmpControlRequst
55
56 --=========
57 RETURN(0)However, when I run this stored procedure, 'PIsExists' would always return -1. I am positive that the values that I passed in, had already existed in the database. Any idea what might be causing this problem? Thanks in advance

I'm about ready to pull my hair out. I have a repeater control, and a date field. If the field is a valid date, I'll use it to calculate and display the person's age. Otherwise, I want to display "N/A". My problem is trying to determine if the date field is null or not.I'm using SQL Server 2005 which allows Nulls in the date field, and for many records I don't have a birth date. It makes sense for these records to leave the date Null. This is my code:Protected Sub Repeater1_ItemDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.RepeaterItemEventArgs) Handles Repeater1.ItemDataBound If e.Item.ItemType = ListItemType.Item OrElse e.Item.ItemType = ListItemType.AlternatingItem Then Dim LabelIcon As Label = CType(e.Item.FindControl("LabelIcon"), Label) Dim LblAge As Label = CType(e.Item.FindControl("LblAge"), Label) Dim inmate As WAP.prisonmembersRow = CType(CType(e.Item.DataItem, System.Data.DataRowView).Row, WAP.prisonmembersRow) If System.IO.File.Exists(Server.MapPath("~/images/picts/" & inmate.FILE2 & ".jpg")) Then LabelIcon.Visible = True End If If inmate.DATE_OF_BIRTH Is DBNull.Value Then If IsDate(inmate.DATE_OF_BIRTH) Then LblAge.Text = "Age: N/A" Else LblAge.Text = "Age: " & GetBirthdate(inmate.DATE_OF_BIRTH) End If End If End IfEnd Sub How can I resolve this?Diane

Without having to update it every day.
This is so no one enters a value higher than the current date.

Basically, I have a membership table that lists each member with an effective period, Eff_Period, that indicates a month when a member was active. So, if a member is active from Jan to Mar, there will be three rows with Eff_Periods of 201501, 201502 and 201503.
All well and good.But, a member may not necessarily have continuous months for active membership. They might have only been active for Jan, Feb and Jun. That would still give them three rows, but with noncontinuous Eff_Periods; they'd be 201501, 201502 and 201506.There is also a table that logs member activity. It has an Activity_Date that holds the date of the activity - betcha didn't see that comin'. What I'm trying to do is determine if an activity took place during a period when the member was active.
My original thought was to count how many rows a member has in the Membership table and compare that number to the number of months between the MIN(Eff_Period) and the MAX(Eff_Period). If the numbers didn't matchup, then I knew that the member had a disconnect somewhere; he became inactive, then active again. But, then I thought of the scenario I detailed above and realized that the counts could match, but still have a discontinuity.So, is there a nifty little SQL shortcut that could determine if a target month is contained within a continuous or discontinuous list of months?

All,
I am facing below problems in migrating my DTS packages to SSIS.
Could any one answer this ?
1.How to do Tranformations based on condition.Earlier in DTS we are using Activex.
For ex:
if isDate(DTSSource("Due Date")) then
DTSDestination("Due_Date") = DTSSource("Due Date")
end if
I am using script component with below logic:
If Not Row.Due_Date_IsNull Then
If IsDate(Row.Due_Date) Then
Row.Due_Date= Row.EntryDate
End If
End If
Is that correct ?
2.My flat file is having 37 columns.But I am able to see only 21 columns;First 20 columns are showing correctly
and remaining data is showing in 21st column.delimiter is semicolon; Any guess ?
Thanks,
Ravi

I have a column say 'ActivationDate' which is a (database timestamp [DT_DBTIMESTAMP]) which I want to replace with an expression in derived columns
The condition is if 'ActivationDate' field is null or '' then 'Null' else 'ActivationDate'
I am struggling to write this condition. Without condition i.e. at present it saves the value in this database '1753-01-01 00:00:00.000'.
In the preview the 'ActivationDate'field does not show any thing so I recon it is either null or ''

I need query which will check user supplied date range is in between the existing table startdate and enddate.
if any of the date of user supplied date range is in between the tables start date and end date,it should retrun that record from table.
for example user supply date range is from 1 may 2012 to 5 may 2012.
then query must check that
1 may 2005
2 may 2005
3 may 2005
4 may 2005
5 may 2005
(all dates) is in between startdate and enddate of existing table.

Hi,
I'm making some sort of application where people can add their resume.
They also need something to add places where they have worked or currently are working.
I have a form where they can add this and i add this experience using the following stored procedure:
GO
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
create procedure [dbo].[sp_Insert_Experience]
@ExperienceId uniqueidentifier,
@ExperienceEmployee nvarchar(100),
@ExperienceFrom datetime,
@ExperienceUntil datetime,
@ExperienceQualifications nvarchar(250),
@ExperienceTechnologies nvarchar(250),
@ExperienceTasks nvarchar(250)
as
insert into Experiences
values(@ExperienceId,@ExperienceEmployee,@ExperienceFrom,@ExperienceUntil,@ExperienceQualifications,
@ExperienceTechnologies,@ExperienceTasks);
It must be possible to add the place where they currently are working. Then the ExperienceUntil has to be something like still going on. Then I decided that the user then had to set the current date.
But what I want is the following, I want that the ExperienceUntil keeps updating automatically, like everytime i get that record, it has to have current date.
Is this possible ?
But if the ExperienceUntil isn't the current date , it just had to take the supplied parameter date.

My goal is to select values from the same date range for a month on month view to compare values month over month. I've tried using the date trunc function but I'm not sure what the best way to attack this is. My thoughts are I need to somehow select first day of every month + interval 'x days' (but I don't know the syntax).In other words, I want to see

I am trying to find a beginning date from multiple date ranges, for example:
RowNumberidBegin dtEnd Dt
107933192014-09-022015-06-30
207933192013-09-032014-09-01
307933192012-09-042013-09-02
407933192011-09-062012-09-03
For this id: 0793319, my beginning date is 2011-09-06
108203492014-09-022015-06-30
208203492013-09-032014-09-01
308203492012-09-042013-09-02
408203492011-12-122012-07-03--not a continuous date range
For this id: 0793319, my beginning date is 2012-09-04
108203492014-09-022015-06-30
For this id: 0820349, my beginning date is 2014-09-02
To find continuous date, you look at the beginning date in row 1 and end date in row 2, then if no break in dates, row 2 beginning date to row 3 end date, if no break continue until last date There could multiple dates up to 12 which I have to check for "no break" in dates, if break, display beginning date of last continuous date.

NUMERIC(8,0) CCYYMMDD?
I tried this...
SET@SQLQuery=@SQLQuery+'ANDMEMBER_SPAN.YMDEFF<='''''+CAST(@AsOfDateASVARCHAR)+''''''+@NewLineChar;
SET@SQLQuery=@SQLQuery+'ANDMEMBER_SPAN.YMDEFF>='''''+CAST(@AsOfDateASVARCHAR)+''''''+@NewLineChar;
but that put it in the format of...
AND
MEMBER_SPAN.YMDEFF<=''2015-04-01''
AND
MEMBER_SPAN.YMDEFF>=''2015-04-01''
Which is close...I think I just need to lose the "-"

I have one column having date in format YYYYMMDD(20070929) and corresponding column in SQL is datetime, but it fails on data type mismatch.
I have no choice of making date column in SQL to string or Varchar etc,
is there any way to make that date column in SQL to convert the value upon transformation from format (YYYYMMDD) to M/DD/YYYY (9/29/2007).
