Works great, if the guy is still alive today...
Your query selects all who have already died past that date - that's a difference.
|
|
|
|
|
Either date_fo_death is null or greater than the given date:
SELECT *
FROM Applicant
WHERE date_of_death is null
OR date_of_death>@somedate
|
|
|
|
|
SELECT
id_Applicant,
name,
date_of_birth,
date_of_death
FROM
Applicant
WHERE
'5/30/2012' BETWEEN date_of_birth AND ISNULL(date_of_death,'1/1/3000')

Just wondering what differences there are between these two connection methods in SSIS? We are connecting to SQL 2008 R2 databases.
Is one better performing than the other? Or is one easier to use? There does seem to be certain tasks that can only use one or the other.

An ADO.net connection will use the native client classes so it is better.

I am trying to insert string date to datetime column with the following way.(Sql2000)
CONVERT(DATETIME, @To, 103)
but this is not saving the DD/MM/YYYY format in the webserver, but it is working in my local machine.In the webserver sql it is saving as MM/DD/YYYY format.
|
|
|
|
|
Use a parameterized query, that will do the magic around the date format.
|
|
|
|
|
It is based on how the systems are setup. Cannot remember the SET command and have to go to work. Sorry.

SET DATEFORMAT DMY

Your string-representation is a culture-dependent format, a way of displaying a date in a specific culture. Date (and time) itself is not a string, but a number.
Make sure it's a DATE column in the database, and pass a Date (not a string) to the query. Use parameters as suggested.
using (var con = new SqlConnection(connectionString))
using (var cmd = con.CreateCommand())
{
cmd.CommandText = "SELECT * FROM SomeTable WHERE MyDate = @MyDate";
cmd.Parameters.AddWithValue("@MyDate", DateTime.Now);
}

the purpose of a database is to store information, not to format it. Store dates and datetimes in fields with the appropriate type, and let your applications take care of formatting when presenting results to the user. Do not try and have the database format stuff, you will get lots of trouble and never get satisfactory results.
And as others have said, use SQL parameters rather than SQL string concatenation, to feed dates and datetimes to the database; thus avoiding all conflicts with regional settings and the like.
|
|
|
|
|
If the column is a DATETIME, then the statement "it is saving as MM/DD/YYYY format" is untrue.
If the output of SELECT thedate FROM table shows different formats when executed on different systems, it is because of the "Region and Language" settings of the systems -- see the control panel -- and this is correct behaviour. If you want to override this behaviour (you shouldn't) then format it via the query.
And I strongly reccommend ISO 8601 format YYYY-MM-DD.

Put it like,
CONVERT( VARCHAR, @To AS DATETIME, 103 ) )

Table-Valued functions are awesome, like a view with input parameters. Like this:
CREATE FUNCTION [dbo].[Function_Name] (@inputParameter int) RETURNS table AS Return (<select clause> <from clause> WHERE <filterFieldName> = @inputParameter [<group by clause>])
Works in sql 2000+.

A quick question about the mapping between CLR types and their TSQL ones.
From what I can see within the CLR you have SQLString and SQLChars which are nvarchar(4000) and nvarchar(max)...what if the callee expects to pass you a varchar(5)?
Can you tell the CLR the length it should expect? Or would you have to specifically code this check?

I wouldn't bother -- the engine will figure it out. And deal with an Exception if one is thrown.

I'm having some trouble with a JOIN that involves an OR (in SQL Server). For example:
SELECT *
FROM TableA A
INNER JOIN TableB B
ON A.Field1=B.Field1
OR A.Field2=B.Field2
Quite correctly this produces two output rows for each row in TableA that matches TableB via both Field1 and Field2* -- but for this JOIN I want to output only one row when both match (preferably the result of the Field1 match, and only report the Field2 match if Field1 doesn't match).
* Clarification -- when it matches two rows in TableB; one via Field1 and the other via Field2.
I haven't done much searching for pointers because I don't think it's possible, however I'm posting here just in case someone here knows of a way or a simple (SQL only) work-around.
Edit -- Here's an example:
SELECT * FROM TableA
ID Field1 Field2
-- ------ ------
10 A E
11 E D
12 A D
SELECT * FROM TableB
ID Field1 Field2
-- ------ ------
20 A B
21 C D
10 will match only 20 ; 11 will match only 21 ; 12 will match both 20 and 21 -- so I want 20.
ID Field1 Field2 ID Field1 Field2
10 A E 20 A B <-- I want this row
11 E D 21 C D <-- I want this row
12 A D 20 A B <-- I want this row
12 A D 21 C D <-- I don't want this row
Luc's and pmpdesign's suggestions yield the same output.
Here's a variation of Bernhard's suggestion, which seems to work:
WITH cte1 AS
(
SELECT A.ID aID
, A.Field1 aField1
, A.Field2 aField2
, B.ID bID
, B.Field1 bField1
, B.Field2 bField2
FROM TableA A
INNER JOIN TableB B
ON A.Field1=B.Field1
)
, cte2 AS
(
SELECT A.ID aID
, A.Field1 aField1
, A.Field2 aField2
, B.ID bID
, B.Field1 bField1
, B.Field2 bField2
FROM TableA A
INNER JOIN TableB B
ON A.Field2=B.Field2
)
SELECT *
FROM cte1
UNION ALL
SELECT C2.*
FROM cte2 C2
LEFT OUTER JOIN cte1 C1
ON C2.aID=C1.aID
WHERE C1.aID IS NULL
