Determining Last Entry ID In Table

Nov 17, 2006

Not sure if this is the right place to post this but hopefully someone can help me. I would like to determine what the last automatically incremented ID is in a table I need to return it as a variable to a VB.NET program but I'm not sure what the SELECT statement would look like for this. Any help would be greatly appreciated.

Determining If A Table Exists

May 2, 2000

How do I find out if a temporary table named '##test' exists? I have a stored
procedure that creates this table and if it exists another stored procedure
should do one thing, if it does not exist I want the SP to do something else.
Any help as to how I can determine if this table exists at the current time
would be greatly appreciated.

Thanks in advance for you help,

Determining Last Time A Table Was Updated (6.5, 7.0, 2k)

May 28, 2002

I am trying to find a global way of when the last time a row in one of my tables was updated or data inserted. I say global because I don't want to drill down through each table looking for modified rows.

I am a DBA of several hundred databases and want to retire those no longer being used.

Is there a column of a system table that has this info.

Custom Stored Procs: Determining Source Table Name

Jan 17, 2006

Hello all ...

I'm looking at writing some customized insert, update and delete stored procs for a replication target. For various reasons I would like to write a "one size fits all" custom stored proc for each of these tasks.

It looks like I can get the data values passed as parameters just fine.

I was wondering if there's a way to also pass the source schema and table name as parameters, or to determine these on the fly in my all purpose stored procs. Some replication products refer to these types of values as "tokens" that can be included in the replication data stream sent to the target.

I can adjust the source database replication publications, and article definitions, but I cannot modify the actual source database tables to include these as values in data columns. It is possible a view that contains these elements as strings might fly, but I was hoping to avoid cluttering the source database.

A handy trick or technique would be helpful!

Thanks!

How Do I Enter NULL In A Table Cell In The Enterprise Manager UI For Table Data Entry?

Sep 9, 2005

I have a column defined as smalldatetime. Default length (4), and "allow NULLS" is checked.In the Enterprise Manager UI, when i enter data into that table row, if i just tab past that column, all is well, and the value is represented in the UI as <NULL>.The problem comes once i ever enter a date into that column.  Say i have entered a date (all is well), and now i want to remove that entry and go back to NULL (after the date value has been committed, different entry session, say).How is that done?It seems to me, once a date has ever been entered into that column, now, if i try to remove it, i get the error "The value you entered is not consistant with the data type or length of the column, or over grid buffer limit".  I have tried deleting the value, entering spaces, entering the string NULL or the string <NULL>; maybe some other tries as well, but none works, i always get that error message and am not allowed to proceed past that cell until i restore a date value to it.  I want to get back to <NULL>.Anybody know?Thank you.Tom

Power Pivot :: Create Measure Within Date Dimension Table To Sum Single Entry Per Month Eliminating Duplicates

Jul 27, 2015

We are trying to do some utilization calculations that need to factor in a given number of holiday hours per month.

I have a date dimension table (dimdate).  Has a row for every day of every year (2006-2015)

I have a work entry fact table (timedetail).  Has a row for every work entry.  Each row has a worked date, and this column has a relationship to dimdate.

Our holidays fluctuate, and we offer floating holidays that our staff get to pick.  So we cannot hard code which individual dates in dimdate as holidays.  So what we have done is added a column to our dimdate table called HolidayHoursPerMonth. 

This column will list the number of holiday hours available in the given month that the individual date happens to fall within, thus there are a lot of duplicates.  Below is a brief example of dimdate.  In the example below, there are 0 holiday hours for the month of June, and their are 8 holiday hours for the month of July.

DateKey MonthNumber HolidayHoursPerMonth
6/29/2015 6 0
6/30/2015 6 0
7/1/2015 7 8
7/2/2015 7 8

I have a pivot table create based of the fact table.  I then have various date slicers from the dimension table (i.e. year, month).  If I simply drag this column into the pivot table and summarize by MAX it works when you are sliced on a single month, but breaks if anything but a single month is sliced on.  

I am trying to create a measure that calculates the amount of holiday hours based on the what's sliced, but only using a single value for each month.  For example July should just be 8, not  8 x #of days in the month. 

Listed below is how many hours per month.  So if you were to slice on an entire year, the measure should equal 64.  If you sliced on Jan, Feb and March, the measure should equal 12.  If you were to slice nothing, thus including all 15 years in our dimdate table, the measure should equal 640 (10 years x 64 hours per year).

MonthNumberOfYear HolidayHoursPerMonth
1 8
2 4
3 0
4 0
5 8
6 0
7 8
8 0
9 8
10 4
11 16
12 8

The Index Entry For Row ID Was Not Found In Index ID 3, Of Table 357576312

Jul 9, 2004

Hi,

I'm running a merge replication on a sql2k machine to 6 sql2k subscribers.
Since a few day's only one of the merge agents fail's with the following error:

The merge process could not retrieve generation information at the 'Subscriber'.
The index entry for row ID was not found in index ID 3, of table 357576312, in database 'PBB006'.

All DBCC CHECKDB command's return 0 errors :confused:
I'm not sure if the table that's referred to in the message is on the distribution side or the subscribers side? A select * from sysobjects where id=357576312 gives different results on both sides . .

Any ideas as to what is causing this error?

Determining Unique Children

Nov 17, 2005

Hi,

I need to be able to identify if a parent has the same child names as another parent.

Have a look at my data (in pic)

Can you think of a SELECT that will count for each parent, the number of other parents including themselves with all the same children's names?

So you would get something like:

Bob | 2
Bill | 1
Glen | 2

thanks,
david.

Determining Database Size

May 9, 2008

Forgive the easy question but I'm afraid it might be also a trick question and I'd like to hear the experts' opinion. I am using SQL Server 2005 Express edition and I know the limitation is 4GB per database. So far none of my users is anywhere near the limit but I have to be prepared for when that day finally comes. As it stands, they use a single database through a program so I have full control over it. There are no fancy backup programs on the system so no fancy recovery models and automatic shrinking can be done - data is only inserted in that database.

My question is simply how can I determine programmatically (I use ADO.Net but it can execute SQL commands just fine) the size of the database as it relates to the limitation? That is, I don't know whether it is the amount of data stored - with or without overhead, or it is simply the size of the *.mdf file (maybe together with the *.ldf file), or whether the 4GB is 4 billion bytes or 2^32 bytes - I just want the same method that the SQL Server is using so that, for example, I can bring up a warning at 90% full and lock out the user at 99% full.

I'd appreciate any insights.

Determining A Range Of Values

Mar 29, 2012

suppose you have a large table with 2 columns

create table tick
(
ID bigint identity (1,1) primary key not null
, price money not null
)

and I want to know 3 things

Starting with ID = 1 through ID = (last)
give me the low and high price (that satisfies the below WHERE clause), and the last ID
WHERE high price - low price = 0.10
and the last ID (last) is the minimum ID to satisfy: high price - low price = 0.10

So the last ID will coincide with the record containing either the low or high price, the problem is you don't know which record in that range has the corresponding high/low price, it could be the first record or the 10,000th record.

I am thinking I need to create two summary tables, maybe calculate the min(ID) that goes down 0.01 then the min(ID) that goes down 0.02, etc...
Then calculate the min(ID) that goes up 0.01 then up 0.02, etc..finally join against these two summary tables to figure out which combination of downSummary and upSummary have a difference of 0.10.

Determining If SQL Statement Is A Query

Jul 27, 2007

Hi,

I have a C# server application which clients can send arbitrary SQL statements to. These can be absolutely anything - creating tables/views, selecting from tables/views, inserts, updates, deletes, you name it.

There are two return parameters from the server method which executes the SQL - a results set containing the data, and a count of the rows that were updated - (either one or the other should be populated depending on the type of command sent to it). To deal with this, what I planned on doing was (pseudocode follows..):

try
{
reader = OpenReaderCursor(statement)
}
catch
{
updatedCount = ExecuteNonQueryCommand(statement)
}

Unfortunately this doesn't really work, as OpenReaderCursor is able to execute Non Queries (eg. UPDATE/INSERT/DELETEs etc) but doesn't give me a row count, and trying the other way round, ExecuteNonQueryCommand is happy to execute SELECT statements, but I can't then of course return a results set as I don't have access to it.

My question then, if you will excuse the waffle above, is "Is there a simple way of determining if a string containing an SQL statement is a query?" - or will I have to come up with some way of dealing with this in my application code?

Please don't slate the design (ideally I would have two methods on the server, one for queries which returns results and the other for nonqueries which returns an updatecount) but there's nothing I can do, this is how it must be done (the interface was defined long long ago)

Thanks for your time, all ideas appreciated

When the operating system is W2K3 or higher I want to take advantage of the "check_expiration, check_policy, must_change' arguments to create login and exclude those features when the host OS does not support them.



Is there an easy way to determine if those arguments are supported?

Determining Null Values In Columns

Sep 7, 2004

How to find out that there is a null value in a column rather than a valid integer, DateTime or bool value, for strings I use 'as' operator to cast the column value and it returns null when column value is null, but for value types using 'as' operator causes compile error and using simple casting causes runtime error, for example:


int count = (int)row["Count"];

and

int count = row["Count"] as int;


the first one throws an exception when Count is null and the second doesn't compile at all since 'as' applies to reference types, so what is the way other than exception handling to determine null value in a column?

Determining If A Local Variable Exists

Jun 11, 2007

Is there a way to determine if a local variable exists or not?

There's a parameter I often use in code called @guid_batch that is usually declared in the parameter of a stored proc, but when in debugging it would be nice to have it available without having to change code.

Is there something that I could do similar to the following


Code:


IF VARIABLE_ID('@guid_batch') IS NULL
BEGIN
DECLARE @guid_batch UNIQUEIDENTIFIER
SELECT @guid_batch = NEWID()
END



Thanks in advance,
