I need to match entries of two tables Survey and Phones . Donno what am I missing on
Tables and example :
Phones
[CaseID], [SurveyID],[DateTime], [TelephoneNumber]
90 13875 2006-01-05 10:31:00.000 2814211345 NULL
90 13875 2006-01-05 10:33:00.000 2814211345 NULL
Survey has following columns
[CaseID], [SurveyID], [CaseStartTime],[Phone]
90 13875 2006-01-05 10:31:00.000 2814211345 NULL
90 13875 2006-01-05 10:33:00.000 2814211345 NULL
There are multiple entries of CaseID in both the tables. When a call is made, there is an entry in Phones table and after that an entry is made in Survey table. Timelag could vary from millisec to 2 or 3 mins.So the way to identify is through timestamp, factoring in mins difference.
I am using this query - does not match correctly though
SELECT t1.CaseID, t1.CaseStartTime,t1.ITS, t2.CaseID,t2.DateTime,
DateDiff("n", t2.DateTime,t1.CaseStartTime)as "Min_Diff"
FROM Survey AS t1,Phones AS t2
WHERE t1.CaseID = t2.CaseID and t1.CaseID=90
and DateDiff("n", t2.DateTime,t1.CaseStartTime) <= 2 and DateDiff("n", t2.DateTime,t1.CaseStartTime) >0
Order by t1.CaseID;
Result
90 2006-01-05 10:33:00.000 47 90 2006-01-05 10:31:00.000 2

Proper relationships? Primary Keys?
I really don't know where to start on this. There is apparently no real relationship between these two tables. In which case, matching them up is going to be sporatic and error prone.
To get the situation right:
A phone call is made. At the start of the call a row is inserted in the Phones table.
At the end of the call a row is inserted in the Survey table.

No it isn't. Really! That isn't the way to design a database.
Why does the survey table not have a foreign key that matches the primary key of the Phones table? (Or if there is the possibility of a many-to-many join - why is there no intermediate table?)
I'm hoping that there is missing information here and you just need to post it. What is the structure of the two tables? (I want DDL or a description of column names, types and primary/foreign keys)

Thanx for your response Colin.
Scenarios : When a call is placed, it writes to Phone Log. After that logic goest to the Survey software and writes the information in Survey log. After writing in the survey log, the interviewer gets to talk to the respondent.
The information I am pulling out is from Phone log and Survey log. There is more complexity to the case as there could be a row in Phone log that does not exist in Survey log and vice versa. So while matching I need to have left and right join information as well. If I cannot resolve in sql, then may be I should work with some scripting langauge and write a prg to match. Can you think of any prg lang I could do this real quick ??

Okay - but that doesn't seem to excuse not having proper primary / foreign keys. Two times *close* to each other really does not cut it. For a database to join things up properly you need to be precise.

That would be slow. Scripting languages are useless for this sort of thing.

SQL - But only if your database is designed right in the first place.
Some questions:
What is the relationship between PhoneLog and SurveyLog? one-to-many, many-to-many, many-to-one, one-to-one
(This is a repeat of something I asked before - I really would like to know because it will help solve your problem) What are the primary keys of each of these tables as it stands now?

Thanx Colin . I will try to answer your questions.
Some questions:
What is the relationship between PhoneLog and SurveyLog? one-to-many, many-to-many, many-to-one, one-to-one
Sorry, I missed response on this one, its one to one relationship. So one entry in Phone can have only one entry in Survey LOG . Just that Phone log might have entries that were not recorded in Survey log and vice versa.
(This is a repeat of something I asked before - I really would like to know because it will help solve your problem) What are the primary keys of each of these tables as it stands now?
Primary Key : I will have to put ID to make the rows unique,I think that might join the rows mentioned in original examples correctly, if I index by unique rows ?? Presently , I parsed the logs and pulled out information and did not set Primary key. I understand it is gross mistake and may be main cause of the issue in first place ! I thot I could make CaseID and timestamps together but then we cannot use it as foreign key as the timestamp will not match in Survey table. Any ideas ?

Hi All,
We use MOM (Microsoft Operations Manager) software to monitor our systems. One problem it alerts us to is SQL blocks. However, it's too noisy and I need to tweak the alert rule. To make my testing easier, I'd like to be able to simply start and stop SQL blocking at my command (rather than wait for usage blocks to occur).
I'm not a SQL expert (by any stretch  ) and I've been looking for a script I could run (maybe in two QueryAnalyzer windows) to force a SQL block to begin. I could then KILL the SPID when I was done testing.
Do any of you know of something like this? Is this so easy, no one would ever post it on the web . If so, please let me know how I should go about this. If it's possible to create blocks without altering data, that'd be best.
Thanks!
Justin

Hi,
How can merge two tables? the select command for the 2 tables are as follows
select groupid, staff.name[created] from groups,staff where groups.created=staff.staffid

------ --------
1 A
2 B
select groupid,staff.name[modified] from groups,staff where groups.modified=staff.staffid
groupid modified
------- --------
1 C
2 D
i have to merge these two output as
groupid created modified
------- ------- --------
1 A C
2 B D
please send me the sql query or please tell me how can i merge these using the dataset or any other solution. I have to implement this in my final year project.
Thanks in advance.

Hi friends:
How i can specify the max and min size of a connection pooling in a OldbConnection ?????
I hope you can helpme
Thanks in advance
|
|
|
|

Documentation says that connection pooling is handled by provider for OleDbConnection. If you are using SQL Server, you can use SqlConnection class, and use the Pooling, Max/Min Pool Size entries in the connection string.

I am writing a stored proc. Currently doing a "SELECT INTO" to copy data from one table to a new one. But eventually
a. I want to do it most optimally as the data is gonna be huge
b. Also it should be able to insert data in an existing table.
What SQL stmt/function should I use?

Hi Guys,
I have not known so much about the SQL Server and MSDE, so just rush to here to get help.
Can any one tell me When records are deleted, is the space immediately compacted or when is it compacted?
and Is the compacting configurable? How to set it up? Since I am using the SQL buddy
For large number of records deleted (eg. Archival), is the database compacted immediately!
Many thanks in advance! I am really appreciate your help.
|

SQL Server does not generally compact free space. To do so, use the Shrink feature (in T-SQL, DBCC SHRINKDATABASE).
To have this occur automatically, set the 'Auto Shrink' option. You can do this in T-SQL with ALTER DATABASE db SET AUTO_SHRINK ON. MSDE has this option turned on by default.
If Auto Shrink is set, the shrinking operation occurs when there is more than 25% free space in the file. The resulting file will have 25% space free or be the size it was when originally created, if that is larger.

Hi Mike,
Thanks very much for your reply. So the compacting is a default option which already be turned on in MSDE? How about SQL Server, the option is also turned on by default?
Is there any way I can configure this option so that it can be performed when there is 10% free space?
Many thanks for your help!!

I have a problem in restoring sql server database in asp.net
I have first written code for full backup and differential backup of database, it is working properly.
For full backup code is :
-----------------
-----------------
objBackUp.Action = SQLDMO.SQLDMO_BACKUP_TYPE.SQLDMOBackup_Database
objBackUp.Database = "tempbakup"
objBackUp.Devices = ""
objBackUp.Files = Server.MapPath("tempbakupFull.zip")
objBackUp.MediaName = Server.MapPath("tempbakupFull.zip")
objBackUp.MediaDescription = "TempBakup Database Backup Full" & Now
-------------------
------------------
For Differential backup :
objBackUp.Action = SQLDMO.SQLDMO_BACKUP_TYPE.SQLDMOBackup_Differential
objBackUp.Database = "tempbakup"
objBackUp.Devices = ""
objBackUp.Files = Server.MapPath("tempbakupDiff.zip")
objBackUp.MediaName = Server.MapPath("tempbakupDiff.zip")
objBackUp.MediaDescription = "TempBakup Database Backup Differential" & Now
But when I used wrote following code for restore databse, I got problem
"The volume on device 'c:\inetpub\wwwroot\TestApp\tempbakupfull.zip' is not part of a multiple family media set. BACKUP WITH FORMAT can be used to form a new media set."
CODE is
oRestore.Action = SQLDMO.SQLDMO_RESTORE_TYPE.SQLDMORestore_Database
oRestore.Database = "TempBakUp"
oRestore.Files = Server.MapPath("tempbakupfull.zip,tempbakupdiff.zip")
oRestore.FileNumber = 1
oRestore.ReplaceDatabase = True
oRestore.LastRestore = False
oRestore.SQLRestore(srv)
oRestore.FileNumber = 2
oRestore.LastRestore = true
oRestore.SQLRestore(srv)

hi all,
i want to select all the jobcode from jobmaster
my query is
SELECT txtjcode,convert(smalldatetime,dtlastdate)as last ,getdate()as tday FROM jobmast
it will work fine
it select entries like
test 2006-01-25 00:00:00 2006-02-01 09:51:05.107
US001 2006-01-25 00:00:00 2006-02-01 09:51:05.107
US002 2006-02-10 00:00:00 2006-02-01 09:51:05.107
but when use the following querry,
SELECT txtjcode,convert(smalldatetime,dtlastdate)as last ,getdate()as tday FROM jobmast WHERE convert(smalldatetime,dtlastdate)>= getdate()
it will select only this data
US002 2006-02-10 00:00:00 2006-02-01 09:51:05.107
and didnt select
US001 2006-01-25 00:00:00 2006-02-01 09:51:05.107
actually my query select both
why happens this so?
any soln to this
"i want to select all data where last date >= today date"
plz help urgent

One solution is that u should only save DATE portion in the datetime field u can send it as
Format(dtPicker.Value,"mm-dd-yyyy")
then ur query will work fine.
Regards,
Javed

What type is dtlastdate and why are you converting it? Shouldn't it already be in a datatime (or smalldatetime) format already?
crazysanker wrote: WHERE convert(smalldatetime,dtlastdate)>= getdate()
It didn't select the row with dtlastdate as 2006-01-25 because that is before now. You asked to select rows with a dtlastdate after now.
>= Greater than or equal to: WHERE dtlastdate is greater than or equal to getdate()
The query is working correctly.

I know you can view the diagram icon, highlight it and click Cut or Copy, but if I go to another database with the same exact schema, how do I "paste" that diagram?
Thanks!
