Proper Use Of Null Values In Stored Procedures
Oct 25, 2000If I have a stored proc which has 2 input variables and for example
the 2nd one is null or not provided what is the best way to turn this null
into a wildcard. If the second one is an int and not provided should I
but a checknull statement in the proc and convert this to a wildcard %. I believe if I do I need to change the where clause "where field1 = @var "
to where field1 like @var". Any input appreciated
SQL Server 2000 - Proper Backup Procedures
Jul 24, 2006Hi everyone I am fairly new to SQL server and need some help with creating backups. I am a little confused whether to append or overwrite my backup data when saving full, differential and transaction log backups to disk. Below is my current backup schedule.
1) A full backup every night at 2:00a.m. that overwrites my existing backup. Should this be an appended backup? Wouldn't my file keep growing? How do I manage the backup file size?
2) Differential backups every two hours that is set to append. How do I stop this file from growing? Should I be controlling the size of my backups through the backup set expiry option?
How do I incorporate transaction logs into my backup schedule and manage the size of the log? Should the log backups also be appended or overwriten?
I appreciate everyones help in advance.
SQL And Proper Concatenation Within VB
Jun 9, 2008Hi all - I have posted inquiries on this rather vexing issue before, so I apologize in advance for revisting this. I am trying to create the code to add the parameters for two CheckBoxLists together. One CheckBoxList allows users to choose a group of Customers by Area Code, the other "CBL" allows users to select Customers by a type of Category that these Customers are grouped into. When a user selects Customers via one or the other CBL, I have no problems. If, however, the user wants to get all the Customers from one or more Area Codes who ALSO may or may not be members of one or more Categories; I have had trouble trying to create the proper SQL. What I have so far:Protected Sub btn_CustomerSearchCombined_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btn_CustomerSearchCombined.Click Dim CSC_SqlString As String = "SELECT Customers.CustomerID, Customers.CustomerName, Customers.CategoryID, Customers.EstHours, Customers.Locality, Category.Category FROM Customers INNER JOIN Category ON Customers.CategoryID = Category.CategoryID WHERE " Dim ACItem As ListItem Dim CATItem As ListItem For Each ACItem In cbl_CustomersearchAREA.Items If ACItem.Selected Then CSC_SqlString &= "Customers.AreaCodeID = '" & ACItem.Value & "' OR " End If Next CSC_SqlString &= "' AND " <-- this is the heart of my problem, I believe For Each CATItem In cbl_CustomersearchCAT.Items If CATItem.Selected Then CSC_SqlString &= "Customers.CategoryID = '" & CATItem.Value & "' OR " End If Next CSC_SqlString = Left(CSC_SqlString, Len(CSC_SqlString) - 4) CSC_SqlString &= "ORDER By Categories.Category" sql_CustomersearchGrid.SelectCommand = CSC_SqlString End SubAny help on this is much appreciated, many thanks --

Going From SQL 7.0 Beta To SQL 7.0 Proper - Problem ...
Jan 14, 1999Greetings, I seem to be getting a problem during installing SQL 7.0 over the SQL 7.0 beta. It tells me that there are ODBC components need to be upgraded and they are read only ... I can find no way of changing this.
Alternatively if I remove the beta and then install the proper version, will all the old db created under the beta still be recognised ?

Proper SQL Backup Procedure

I have been told that simply stopping the SQL server service and backing up the data directory is all I have to do to do a backup of my data. Is this accurate?

Proper Place For Sub Select?
Feb 14, 2013I have a very simple query that gets a field to use as constraints in another query.
Code:

M.Serial, M.Name, M.Acres, M.District,
V.YearBuilt, V.Code, V.Size,
(SELECT SUM(V1.Acres)
FROM TRValue V1
WHERE V1.Year = V.Year and V1.Parcel = V.Parcel and

My question is How can I fold the first query into the second?
Proper Way Of Linking Tables?
May 2, 2015I am no stranger to Databases, I worked a lot with MySQL but never really cared about proper DB design as long as it worked. Now I am playing with SQL in a ASP.NET project and want to get things done the right way.Let's say I have a Movies database. My movies can have multiple genres so I set my tables up like this:
[Movies]
MovieID
MovieName
MovieRelease
[code]....
Is this the proper way of doing things? The problem with this is when I want to enter a record manually I have to know the ID of the movie and the ID of the Genres of the movie. And what about naming conventions? By default the identifier is always Id, from my MySQL experience I liked naming it like the table, same goes with other columns. This is my T-SQL code for above tables in VS-2013.
CREATE TABLE [dbo].[Movies] (
[MovieID] INT IDENTITY (1, 1) NOT NULL,
[MovieName] VARCHAR (50) NOT NULL,
[MovieRelease] NUMERIC (18) NOT NULL,
CONSTRAINT [PK_Movies] PRIMARY KEY CLUSTERED ([MovieID] ASC)

Convert To Proper Date
Apr 16, 2007I read some questions where questioners ask "Sometimes client gives data where dates are expressed as float or integer values.
How do I find maximum date?".
Ex
March 02, 2006 can be expressed as
02032006.0
020306
2032006
20306
020306.0000
2032006
Assuming the values are expressed in dmy format
The possible way is convert that value into proper date so that all types of date related calculations can be done
Create function proper_date (@date_val varchar(25))
returns datetime
as
Begin
Select @date_val=
case when @date_val like '%.0%' then substring(@date_val,1,charindex('.',@date_val)-1)
else @date_val
end
return
cast(
case
when @date_val like '%[a-zA-Z-/]%' then case when ISDATE(@date_val)=1 then @date_val else NULL end
when len(@date_val)=8 then right(@date_val,4)+'-'+substring(@date_val,3,2)+'-'+left(@date_val,2)
when len(@date_val)=7 then right(@date_val,4)+'-'+substring(@date_val,2,2)+'-0'+left(@date_val,1)
when len(@date_val)=6 then
case when right(@date_val,2)<50 then '20'
else '19'
end
+right(@date_val,2)+'-'+substring(@date_val,3,2)+'-'+left(@date_val,2)
when len(@date_val)=5 then
case when right(@date_val,2)<50 then '20'
else '19'
end
+right(@date_val,2)+'-'+substring(@date_val,2,2)+'-0'+left(@date_val,1)
else
case when ISDATE(@date_val)=1 then @date_val else NULL end
end
as datetime
)
End
This function will convert them into proper date
select
dbo.proper_date('02032006.0') as proper_date,
dbo.proper_date('020306.000') as proper_date,
dbo.proper_date('02032006') as proper_date,
dbo.proper_date('020306') as proper_date,
dbo.proper_date('20306') as proper_date,
dbo.proper_date('020306') as proper_date
Apart from converting integer or float values to date, it will also convert date strings to date
Select
dbo.proper_date('March 2, 2006') as proper_date,
dbo.proper_date('2 Mar, 2006') as proper_date,

Transact SQL :: XML Not Using Proper Index?
Aug 26, 2015I have two xml queries that take long: the 1st query takes about 5 minutes (returns 700 rows) and the 2nd query takes about 10 minutes (returns 4 rows). The total rows in the table is about 2 million. There are three secondary indexes: Property, Value and Path in addition to the clustered index on CardID and Primary XML index. Here is the table definition:Â
CREATE TABLE [dbo].[Cards]
(
[CardId] [int] NOT NULL,
[Card] [xml] NOT NULL,
CONSTRAINT [PK_dbo_Cards_CardId] PRIMARY KEY CLUSTERED
([CardId] ASC)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
[code]...
Looking at the execution plan, the query uses the Primary XML Index even if I add any of the secondary xml indexes. My question is why does not the optimizer use the Property 2ndary index instead of the Primary XML Index? Microsoft recommends that creating a Property index for Value() method of the xml datatype would work to provide a performance benefit. What would be another alternative to make the query run faster?
Proper Format Of BufferTempStoragePath
Dec 11, 2006Hello, I have one package that seems to have continuous problems with memory. As of right now it loads a little over 1 million records. I tried leveraging the property, BufferTempStoragePath, but I don't seem to have the right path name. What sort of path do you put there? File? Folder? If it is a file, what sort of file should it be... text, dat, xml? If someone could point me in the right direction it would be greatly appreciated. Thanks.
PS: Below are the error messages I am getting:
[DTS.Pipeline] Information: The buffer manager detected that the system was low on virtual memory, but was unable to swap out any buffers. 4 buffers were considered and 4 were locked. Either not enough memory is available to the pipeline because not enough is installed, other processes are using it, or too many buffers are locked.
[DTS.Pipeline] Error: The buffer manager cannot create a temporary storage file on any path in the BufferTempStoragePath property. There is an incorrect file name or no permission.
Proper Use Of Event Notifications
Apr 19, 2006Hi.
I'm developing an app that uses Service Broker queues to allow a customer to create "events" that fire using a timer or a query notification. When these events fire, a message is sent to a Service Broker queue for processing. Because there is much managed code involved in processing these messages, I decided to use the External Activator application and an Event Notification to process these messages. My question is "what is the difference between using the External Activator application to launch another application (which simply RECEIVEs a message from the target queue and processes it) and creating a windows service that simply monitors the target queue (with a WAITFOR = -1 clause) and processes it?"
I guess I'm not sure how using the QUEUE_ACTIVATION Event Notification is really helping me.
Thanks,
Chris
Getting Date Into Proper Format
May 22, 2007Hi,
I have a .csv file that lists date like this: "20070522", no hyphens or spaces. In the file connection manager I have the column defined as string. The database column is a datetime.
When I attempt to load the file to the table, I get this error:
[OLE DB Destination [9]] Error: There was an error with input column "effective date" (155) on input "OLE DB Destination Input" (22). The column status returned was: "The value could not be converted because of a potential loss of data.".
My question is, what do I need to do to this column so that I can load it into the database?
Thanks much

Proper ADO Usage Where Conflicts Will Arise
Dec 3, 2006Hi everyone, I'm creating a ASP.NET 2.0 web application utilizing sql server 2000 as a database. My problem revolves around multiuser acces with long running processes. Some of the pages in the application have long running processes against large tables in the database, lets say that take 2minutes to complete. My problem is how do I utilize ado properly in the rest of my application to display a message to users who may try to access data associated with a table while in the midst of one of its long running processes? For instance I would like to notify the user that "Table X is currently locked, please try again in a few minutes".Do I catch sqlException and examine the .Number property? Any insight is appreciated.
Thanks.

View 1 Replies View RelatedProper Sorting Of Months In DropdownList
Apr 6, 2006I'm having an issue getting the data how I want it from SQL to then populate my dropdownlist.
I have a table called SALES_BUDGR_TBL that contains alot of columns but the ones I'm focusing on are SRCURM (Month) and SRACYR (Year). What I need to do is populate a dropdownlist and show the current month first and then work backwards. The data in the dabase goes back 14 months. I created a reference table called MonthOrder that has 3 columns, MonthID, MonthName and MonthAbrv. I did this so I have a way of saying which month belongs where when sorted.
Here is the select statement I currently have. I'm joining the tables and then I want to Order by the MonthID, but I would also like it to show the 2006 records first, then goto 2005, starting with December and going down of course.
Is there anyway to do this? My Select and Results are below...
SELECT DISTINCT SB.SRCURM, SB.SRACYR, MO.MonthID, MO.MonthName FROM SALES_BUDGR_TBL SBINNER JOIN MonthOrder MO ON SB.SRCURM = MO.MonthAbrvORDER BY MO.MonthID DESC

MS SQL 2000 Database Backup - Proper Way To Do It
Dec 3, 2007Dear all
I am pretty new to the database administration and was wondering if i could get some advice here so i have a head start.
Unfortunalety i have came to the conclusion the hard way that the SQL Agent on Ms SQL 2000 doesnt work properly when it comes to database backups. I discovered that the backups it creates and it claims that are performed succesfully do not work.
So i was wondering what would be the proper way to go in creating a backup of a highly critical database. The database is in MS SQL 2000. I am not required to have the application roll over to the backed up data in case the main one crashes. But it is absolutely necessary to be able to restore the databse to a most recent working copy. So i guess performing a backup once a day would do. Loosing data from a day would not be such a big deal since i have other ways of restoring that days data, as long as i have the full database up to the previous day.
I was looking at database mirroring but that is not available with sql 2000.
Also i though of as a possibility to run a replication on the SQL 2000 database and replicate to SQL 2005 database which aparently has got the SQL agent working properly.And then run the agent on the SQL 2005 database which would backup the copy daily?
Any advice is apreciate and if there are any white papers or books i could look at that would be great.
Cheers
Converting A String Expression To Proper Case

How To Put Few Hundred Million Strings In Proper Case
Sep 16, 2015First off, I know this is a presentation issue. Second, no, I can't force a change on my source systems.
Some of the systems that send my BI application data, send that data in all upper case like so "JOHN DOE". We have this horrible SQL function that goes through and makes sure that the first letter in a word is always uppercase and the rest of the letters are lower case. So my results are "John Doe".
As you can imagine this is dreadfully slow when executed a couple of hundred million times, but what are my options?
I have not used Data Quality Services yet, but the chart in BOL says a DQS SSIS cleansing task can do 1 million records in 2 hours on a given set of hardware. That is still pretty horrible.
I suppose I could cobble together a Script task in SSIS, but I am pretty sure clumsy dotNet is not going to be much faster.

Perfomance Enhancement Through Proper Database Designing
Jul 20, 2005Dear ReaderI am trying to design a database. How can I make best Judgement that Indexing (which I am trying to fix during Diagram Desingning process)is ok.I am able to identify the best candidate for the indexing.Below is the details I want to understand:AreaZIPCityCountyDistrictState/ProvinceCountryNow I want the data retrival optimization through Index. (you can suggest another idea, also)Entities Area,...., Country have independent tables.Example:Area_TableAreaID (PK)AreaThey have relationship- one to many- if you go from Country to Area.There is one more table:Location_Table (PK)LocationIDAreaIDZIPIDCityIDCountyIDDistrictIDState/ProvinceIDCountryID(Location_ID is further related to the Address of the contact.)GUI has a single form to enter these details.On a save command details in all the tables -Area to Country- (individually) being inserted.& simultaniously Location_Table is also being inserted with the details.Following is the situation of being queried these tables:(1) GUI user can select an Area than the related details of ZIP .., ..., ...upto Country etc. should be loaded automatically (id it is previously stored by the user entry in the database.)(2) Contacts have to be retrived on the basis of Area, ZIP, .....County. (Necessary Groupings are required )Example:If Contacts are queried Country Wise then the Display should beCountry1State1District1County1City1ZIP1Area1Area2ZIP2City2County2District2Country2Please Guide.SuryaPrakash****************************************** This message was posted via http://www.sqlmonster.com** Report spam or abuse by clicking the following URL:* http://www.sqlmonster.com/Uwe/Abuse...0255a1765491f15*****************************************
View 5 Replies View RelatedIn Cursor: Help To Perform Proper Comparison Using Variable
Jun 7, 2006Hi All,
I failed to find record when using variable in cursor in WHERE clause:
ID is uniqueidentifier field in the table
DECLARE @EncounterID uniqueidentifier
........
WHERE ID = @EncounterID -> this does not work, though @EncounterID is set properly and can see its value in debugger
WHERE ID = 'E3AE2C5B-06F2-4A3C-A3A4-7D6CC43DE012' -> this works fine and record found
Tried to CAST(@EncounterID as char(40)) but still no luck.
I would greatly appreciate any advise hot to make it working.
Thank you very much in advance
