HI:
Is there any algorithim, which can help me write a script or SQL that will select all the points within a Closed Polygon.
This polygon and point data have latitude and longitude information
Help will be appreciated.
Thanks

I have a table which hold records that contain all the lat/long points. I want to select all records that are within a polygon. Server 2008...

Here is some basic code, with long coordinates data.

(1 row(s) affected)As I read that there is a distance of about 7864 meters, this is close to what I would expect, so that's ok. The point outside I would expect a distance as well so that is confusing.. Then we have the intersects, it says that the point inside does NOT intersect but the one outside DOES, this is backed up by the intersection values.
Dear experts,
Hi, I got a table name Employee, with the following fields
EmployeeID
Name,
ManagerID
ManagerID2,
ManagerID3,
ManagerID4 ..
ManagerID, ManagerID2, ManagerID3, ManagerID4 are all pointing to EmployeeID in the same table.
Now I want to select the all employee records where the manager NAME is like '%Raymond%'. (i.e. any of the four managers name is like '%Raymond%'.
How do I construct the select query? I tried this, but it does not work if there are more than 1 manager named 'Raymond'
DECLARE @Name varchar(50)
SET @Name = '%Raymond%'
DECLARE @EmployeeNumber nvarchar(50)
Select
@EmployeeNumber = EmployeeID
from
Employee
where
[Name] like @Name
SELECT
'HumanResources.Employee' as TableName,
E.[Name] as EmployeeName ,
isnull((Select [Name] from Employee E2 where E2.EmployeeID = E.ManagerID),'') as Manager1,

Greetings everyone, I'm posting this thread with the hope that someone will notice it and might offer me a helping hand regarding one of my problems.I have the database named "DBEXAMPLE" with the table MEMB_INFO that contains two important columns that are named cur_points and points where cur_points column contains the total available points that a member can use/spend on a game and the points column stores the total of the points that a member used so far.So as i plan to wipe all data of the database, i need to keep the member login,password and total points that each member purchased.So i will somehow need to update the cur_points column with the total of current cur_points+points columns and then wipe points column.I've personally asked a friend regarding this and he said that this should be something complicated and it might require php also.Really appreciate if someone could help me regarding this.small schema:Database: DBEXAMPLETable: MEMB_INFOColumn cur_points -> total available points that a member can spendColumn points -> total points that the member has already spentColumn memb___id -> member login aka account idTODO -> update cur_points column with the total of cur_points+points columns for each member(buyer)With best regards.
View 5 Replies View RelatedI'm running the following SQL query from LabVIEW, a graphical programming language, using the built in capabilities it has for database connectivity:
   DECLARE @currentID int
   SET @currentID = (SELECT MIN(ExperimentID) FROM Jobs_t WHERE JobStatus = 'ToRun');
   UPDATE [dbo].[Jobs_t]
   SET [JobStatus] = 'Pending'
   WHERE ExperimentID = @currentID;
   SELECT @currentID AS result
<main.img>
This is the analogous code to main() is a C-like language. The first block, which has the "Connection Information" wire going into it, opens a .udl file and creates an ADO.NET _Connection reference, which is later used to invoke methods for the query.
<execute query.img>
This is the inside of the second block, the one with "EXE" and the pink wire going into it. The boxes with the gray border operate much like "switch" statements. The wire going into the "?" terminal on these boxes determines which case gets executed. The yellow boxes with white rectangels dropping down are invoke nodes and property nodes; they accept a reference to an object and allow you to invoke methods and read/write properties of that object. You can see the _Recordset object here as well. <fetch recordset.img>
Here's the next block to be executed, the one whose icon reads "FETCH ALL". We see that the first thing to execute on the far left grabs some properties of the recordset, and returns them in a "struct" (the pink wire that goes into the box that reads "state"). This is where the code fails. The recordset opened in the previous VI (virtual instrument) has a status of "closed", and the purple variant (seen under "Read all the data available") comes back empty.
The rest of the code is fairly irrelevant, as it's just converting the received variant into usable data, and freeing the recordset reference opened previously. My question is, why would the status from the query of the recordset be "closed"? I realize that recordsets are "closed" when the query returns no rows, but executing that query in SSMS returns good data. Also, executing the LabVIEW code does the UPDATE in the query, so I know that's not broken either.

View 8 Replies View RelatedI've got a table with lat/longs for specific points:
CREATE TABLE [Point] (
[PointID] [int],
[Lat] [numeric](10, 6),

I have another table with polygon borders as lat/longs:

What I need to do, is come up with a script that will determine which Polygon contains each point. I'd like to be able to assign a PolygonID to each record in the Point table, or give it a 0 if there is no polygon that contains that point.
I'm looking for a way to do this within SQL Server (or possibly with the use of an extended stored procedure if necessary).

I am working on a report which requires me to draw two polygons (rectangles) on a scatter chart to visually indicate "good" and "bad" ranges of plotted data. Is there a way to do this out-of-the-box?
Otherwise, if I must create a custom report item, how do I draw on the chart surface? I have looked at the following articles on Custom Report Items, but when I open the sample solutions I can't put the custom report items on the chart surface.
http://blogs.msdn.com/chrishays/default.aspx
http://msdn2.microsoft.com/en-us/magazine/cc188686.aspx
Do I have to create a custom report item which inherits from a chart control? If so, does anyone have any reference samples?
I have a table that contains spatial points and the name of the polygon they belong to (geography and varchar columns). I need to write a function to accept a point and determine which polygon contains that point. How can I write the query so that it will search through each polygon (derived from the geography points found in the table) and return the name of the polygon that contains that point?

A while since I have posted a question, and this one is probably real easy.
I am trying to store numeric values from a php form in MSSQL 2000 database. However, the columns are set to float and if the value is 1.00, when entered into the table it is saved as 1
If I change the column type to money, the query fails, with an error message of conversion of datatype varchar to datatype money statement terminated.
anybody know what I need to do? do I need to do something in my query to specify that this is NOT varchar data?
Not sure if this is possible, but maybe. I have a table that contains a bunch of logs.
I'm doing something like SELECT * FROM LOGS. The primary key in this table is LogID.
I have another table that contains error messages. Each LogID could have multiple error messages associated with it. To get the error messages.
When I perform my first select query listed above, I would like one of the columns to be populated with ALL the error messages for that particular LogID (SELECT * FROM ERRORS WHERE LogID = MyLogID).
Any thoughts as to how I could accomplish such a daring feat?
Hi, not exactly too sure if this can be done but I have a need to run a query which will return a list of values from 1 column. Then I need to iterate this list to produce the resultset for return.

set @OwnerIdent='A12345B'
SELECT table1.val1 FROM table1 INNER JOIN table2
ON table1. Ident = table2.Ident
WHERE table2.Ident = @OwnerIdent
'Now for each result of the above I need to run the below query
SELECT Clients.Name , Clients.Address1 ,
Clients.BPhone, Clients.email

I know how to create mount point in windows 20003 cluster, I am not sure how
to set it up with SQL 2005 running on the cluster.
Does sql need to be dependant on any of the disks? I have tried looking for
a guide, but cannot find.
current setup active active cluster running. I need to add san space which
will hold the databases. The san will be carved up into drive letters. each
drive letter will hold 3 mount points.
ie.
node 1
J:-2 mount point
k:2 mount point
l:2 mount point
node 2-
r:-2 mount point
s:2 mount point
t:2 mount point
each node would be able to own the disk if the other node failed over.
any help is appreciate. I have tried books online etc.. cannot find a good
step by step.;
thanks
HI All,
I use MSSQL as my database and ASP.NET as my front application. I want to display Price value S$23.68.
The dayatype I used is smallmoney, but it display: S$23.6800. HOw do I control the number of decimals point in the column of MSSQL??
Thanks a lot
Suigion
I understand mount points help scalability in easier maintenance.
By scalability do we mean more than 26 drive letters or it means adding more space to the same mount point letter on with more ease .
Can I add more space to a mountpoint if required later on by adding hard disks .
Also if one can give some pointers to good file group configuration guidelines / storage align partitions , it will be very much helpful
Further I my server CPU has 4 cores , will having 4 filegroups help me in improving system performance.
If SAN has 2 controllers , is it preferred to run data file partition on one controller and log file partition on another.
Thanks in advance.

Hi allI have a large data set of points situated in 3d space. I have a simpleprimary key and an x, y and z value.What I would like is an efficient method for finding the group ofpoints within a threshold.So far I have tested the following however it is very slow.---------------select *from locations a full outer join locations bon a.ID < b.ID and a.X-b.X<2 and a.Y-b.Y<2 and a.Z-b.Z<2where a.ID is not null and b.ID is not null---------------If anyone knows of a more efficient method to arrive at this results itwould be most appreciated.Thanks in advanceBevan

i've got two decimal numbers in columns
closingUnits = 25093.53640
closingAmt = 59110.33
i use a derived column transformation to generate a string column which is the division of those two above.
mystrfield = closingAmt /closingUnits = 2.355599
what i want is cast it to just 4 decimal points when i run the expression below it cast it to 4 decimal points but it doesn't do any rounding.
the value i get is 2.3555 when i should get 2.3556
(ISNULL(closingAmt ) || closingUnits == 0) ? "0.0000" : ((closingAmt / closingUnits) < 1 && (closingAmt / closingUnits) > -1 ? "0" : "") + (DT_WSTR,15)(DT_DECIMAL,4)(closingAmt / closingUnits)
Hi all,
I am seeking your expertise to create SQL codes (SQL server 2005) that can help me to answer the problem below.
I have two tables (points and station), presented in form of SQL codes below. I€™d like to find the 6 closest panels for each of the station. As can be seen in the result table below, the 6 closest panel names are arranged from the first closest (P1) to the sixth closest (P6). Similar procedure also applies for the distance column arrangement. This distance column (D1 €“ D6) is the distance of panels P1 €“ P6 to the station. The distance between two points (with x-y coordinates) can be calculated using a simple Cartesian formula:
Distance = ( (X1 €“ X2)2 + (Y1 - Y2)2 ) 0.5 . As the sample, distance between station €˜A€™ and panel €˜P19-04W€™ is = ((737606.383 - 737599.964)2 + (9548850.844 - 9548856.856)2) 0.5 = 8.79.

Can anyone point me to a book or give me a cookbook recipe for creating a proxy table in Sybase 12.5 that points to a MS SQL Server 2005 table?
I have searched the forum, Sybooks, and BOL and it appears that it can be done.
The total quantity(sum(woitem.qtytarget) as total) result set is showing more than 6 numbers after the decimal point (example:442.2565485). How can I limit it to 2. (example:442.25)
select wo.num, sysuser.username,sum(woitem.qtytarget) as total
from woitem
join wo
ON wo.id = woitem.woid
Join moitem
on moitem.id = woitem.moitemid
Join mo
ON mo.id = moitem.moid
LEFT JOIN SYSUSER ON mo.userid = sysuser.id
group by sysuser.username, num
ORDER BY CAST( REPLACE( wo.num, ':', '.') as decimal(12, 3))
The parent table has the column OrderID which is the primary key. There is a unique non-clustered index in the same table with the same column and some included ones. A child table references the parent table on the OrderID column. Unfortunatelly, in the sys.foreign_keys table the index that has been used to acomplish the referential integrity is the unique non-clustered one instead of the primary key (which is the clustered index as well).
This is causing issues in some maintenance tasks where we need to disable all the indexes of the table apart from the clustered index. Disabling these indexes leeds to disabling the not properly configured foreign key as well. Maybe dropping the index create the constraint again and then recreate the index is a workarround but I wish to have something more elegant and future proof.
