finding the first value to cross a specific threshold in SQL Server
LoadTemp1 LoadTemp2 LoadTemp3 TimeStamp
300 350 200 12-10-2013 13:30
177 238 333 12-10-2013 13:05
240 190 170 12-10-2013 12:45
How do I design query to find the first LoadTemp* that cross a threshold of 340 degrees per TimeStamp.
I've got a fairly large hierarchy table and I'm trying to put together a query to find the lowest level descendants of the hierarchy. I think there must be some way to use the "Breadth-first" approach that's stated in the MSDN technet sites about SQL Server HierarchyID but i'm not sure how to write the necessary T-SQL to traverse that. I know I can get all the descendants of a parent node like this
SELECT *
FROM AdventureWorks2012.HumanResources.Employee
WHERE OrganizationNode.IsDescendantOf(@ParentNode) = 1
However, this query returns all levels for that parent's branch. If I just wanted list of employees that were at the lowest level of the branch(es) for this parent node, how would I do this?
Does anyone know how to query a field in a table where it contains anASCII code >= 128 - without looping through every field for everyrecord in table (using charindex)?Ex of char I would like to find: ü which is char(252)

I have 2 tables with 2 fields in common between them. How do I get a count of rows in table 1 but not in table 2 matching those 2 fields? Thanks.
I have a script that creates these spin off tables (used for lightning fast access) on a near daily basis. But it is possible the table does not exist for that day - in which the script need to check one day back - so on and so forth until finding the most recently created table.
The script I have written fails with overflow error.
I was hoping someone could tell me the correct syntax to accomplish this and also why i recieve this overflow error...
Code:
Dim str_SQL_Asset_1
daysBack = 1
tblFound = FALSE
Dim xbl_Holdings_date
Dim xMonth
Dim xDay
xbl_Holdings_date = date()
If Len(Month(xbl_Holdings_date))=1 Then
xMonth = "0" & Month(xbl_Holdings_date)
Else
xMonth = Month(xbl_Holdings_date)
End If
If Len(Day(xbl_Holdings_date))=1 Then
xDay = "0" & Day(xbl_Holdings_date)
Else
xDay = Day(xbl_Holdings_date)
End If
DO WHILE tblFound = FALSE
xbl_Holdings_Name = "xbl_Holdings_" & Year(xbl_Holdings_date) & "_" & xMonth & "_" & xDay
SQL_tblCheck_STR = "SELECT * FROM INFORMATION_SCHEMA.TABLES " & _
"WHERE table_name = '" & xbl_Holdings_Name & "' "
Set MM_checkCmd = Server.CreateObject("ADODB.Recordset")
MM_checkCmd.ActiveConnection = conn_str_ClientDB
MM_checkCmd.Source = SQL_tblCheck_STR
MM_checkCmd.CursorType = 0
MM_checkCmd.CursorLocation = 2
MM_checkCmd.LockType = 3
MM_checkCmd.Open()
IF MM_checkCmd.EOF Then
xbl_Holdings_date = (xbl_Holdings_date - daysBack)
daysBack = daysBack + 1
tblFound = FALSE
ELSE
tblFound = TRUE
MM_checkCmd.CLOSE()
SET MM_checkCmd = Nothing
END IF
loop
The goal of this snippet is simply to identify and set the value for the existing table name.
An example table name would be "xbl_Holdings_2006_12_10".
I could have posted this question in the VB forum but I would like to push as much of the work onto SQL as possible and also - this sort of operation is more likely to be required of a dba imo.
Is there a way i can create a query that gives me a list of all the table names in the database?
View 2 Replies View RelatedI'm trying to find the primary key on a given table in SQL Server 2000 using SQL. I'm querying the sysobjects table to find a given table, and then querying the sysindexes table. I've ALMOST found what I'm looking for. I see the indexes and columns etc. on the tables in the database, I just don't see the field that indicates that the index is the primary key.
Can anyone help?

Need some suggestions on what to check or look for.My stored proc is not finding the table in the sql db. This is the error...Invalid object name 'tblServRec'I use the same function to pass in an arraylist and the sp name for another sp and that one works ok.The sp is the same as another one except for the table name and that one works ok.The sp works fine on my local machine. It finds the table ok. But when I try it on the server, it doesn't work.I have checked permissions, and they are the same for all tables, even the one that the other sp works ok on the server.Here is the sp if that will help.....CREATE PROCEDURE dbo.deleteServRec

Hi Friends,
Is there any way to find the time when the last DDL was happened in a table?
For example: The time when the new column(s) were added into a table or changed the datatype.
Thanks for the help in advance.

Is there a way to find out when the last modification or change to data in a table occured ? How about the last change of a view ?
We'd like to be able to extract data to another table based on a view. Then, at a later date, check to see if the first table or view has changed since the last extract. If not, then we don't need to re-extract the data, we know it hasn't changed.
Can this be done easilly through a stored proc?

Hi i've to table where i have a product code and a area code.
I want to insert the values from table 1 into table 2 if the product code and area code do not already exists in the table in table 2.
Am using this code below but it does not seem to be working.
select distinct p_code1, area_code
from table1
where not exists
(select p_code, area_code
from table 2 )
A client has a site, that requires users to log in, and each login is logged with IP in this table:
CREATE TABLE [dbo].[Event](
[EventId] [int] IDENTITY(1,1) NOT NULL,
[EventTypeId] [int] NOT NULL,
[IP] [varchar](50) NULL,
[UserId] [int] NULL
[DateCreated] [datetime] NOT NULL CONSTRAINT [DF_Event_DateCreated] DEFAULT (getdate()),
CONSTRAINT [PK_Event] PRIMARY KEY CLUSTERED
(
[EventId] ASC
)
How the client wants me to write a query, that will find "suspected abuse of accounts" - defined by being successful logins made within one hour from at least 3 different IPs.
So I need to check for events, that are within one hour from each other (datecreated field) and have the same userID - and EventTypeId - but at least 3 different IPs.
Maybe it's just late in the day or I am overworked, but I cant seem to find an effective way to approach this.
Ideas?

View 3 Replies View RelatedOK, this should be an easy one but my brain isn't quite working right now.
I have a table, we'll call Table1 like so:
ProductID Supplier Cost

And I want to Get the name of the Supplier with the Lowest cost,
I know I can go like:
SELECT ProductID, MIN(Cost) FROM Table1 GROUP BY ProductID
and get the lowest cost, but what would be the most effiecent way to get all three fields returned by the query? I need the ProductID, Supplier and Cost.

View 2 Replies View RelatedHi, this seems to be an easy question but I can't find a quick answer to it.
I have an asp page that communicates with a database and I want the following example to work...
Insert 5 records into the DB with primary keys 1-5.
Remove record with key number 2.
Now, if I insert a new record I want it to take the smallest available key number (in this case number 2). This will save space in the database and keep the key numbers from increasing forever.
Does auto increment work like this?
If not, how do I do it?
Thanks for any replies!

Hi,
My database is case insensitive. However, the application is case sensitive for the data in the table.
I need to find out the data from the table where the data is stored in lower case.
Here is the sample data:
Table: inv_manager
column: sku varchar(5)
Data: 1134X
1135x
1123a
b145Y
I just need query to return row 2, 3, 4.
Here is my query:
select sku from inv_manager where sku like lower('%[a-z]%')
The problem is it returns all the rows from the table including first one.
How can I return just the data with lower case ?
Thanks

View 1 Replies View RelatedI'm using sql express 2005. I need help with buliding a view.
I'm trying to join two tables and then, if duplicate ID's exist, retrieve the row with the lowest value in a specific column.
For instance:
TableHousehold:
ID Name Status
001 The Smith€™s A
002 The Jone€™s A
003 The Adam€™s A
004 The Grant€™s A
TableResidents
Pk HouseholdID ResidentID Name Gender
1 001 1 Mary Smith F
2 001 2 Jason Smith M
3 001 3 Rachel Smith F
4 002 1 Mike Jones M
5 002 2 Sara Jones F
6 003 2 Erik Adams M
The resident ID is auto increment and assigned by the server. It is possible for resident 1 for each household to have been deleted. It is also possible that a household does not contain any residents. Therefore, I wish to join these tables and return this:
ID HouseHoldName Status ResidentName Gender
001 The Smith€™s A Mary Smith F
002 The Jone€™s A Mike Jones M
003 The Adam€™s A Erik Adams M
004 The Grant€™s A null null
There are other columns in both tables that I will want to join, but for simplicity, the above example illustrates my need.
I was able to accomplish this by creating two views. But I€™d like to try and do this in one.
