Query For Ip And Associated Country

Dec 28, 2007

Hi,

I have created some statistics for my site based on the ip of the visitors. For that reason I have created two tables
1. One table with a column which hold the ip number of the visitor
Table: AccessLog
Column: IP

2. One table with the ip range and the countries
Table: Countries
Columns: ip_to, ip_from, country_name

I would like to create a query which will bring the country name of the visitor IP which IP will be like "ip_to <= ip <= ip_from"

Thanks

Select Unique Country / Date Pairs With Self Join

Sep 16, 2013

I have built a sample table, query, and results for this question. I am using SQL server.

declare @TableX Table
(
Date Date not null,
ID int not null,
Tick varchar(6) not null
)
INSERT @tableX

[Code] ....

Expected results:
DATE(No column name)count
2013-09-02LON1
2013-09-03LON1
2013-09-04LON1
2013-09-05LON1
2013-09-06LON1
2013-09-02USA2
2013-09-03USA2
2013-09-04USA2
2013-09-05USA2
2013-09-06USA2

I want to select unique country - date pairs. It is not even necessary to have the count of each one, just the list of unique country/dates.

My query here uses 'group by' to accomplish this task, but there may be a way to do this with a self join. I believe using a self join would make the query faster.

1) Is this possible to do with a self join?

Get Percentage With Variation Of Field Values (country Names)

Sep 14, 2006

Any help here would be greatly appreciated...

Unfortunately, data wasn't filtered prior to getting inserted into this table. Now I am stuck with cleaning it up. I have thought about writing a query to update all the values, but there are just too many variations, including spelling mistakes, so I've ruled that out as a possible solution.

I have a table which has a Country field but the values per record vary. For example US, U.S., USA, United States, UK, United Kingdom, Canada, Can, etc. I'm trying to find the percent of records per country.

Sample table data: mytable
Id Name Country
1 John     US
2 James UK
3 Jane     United States
4 Mary    Canada
5 Jack     U.S.
6 Tony     United Kingdom
7 Jeff       US
8  Tom     Canada
9  Beth     UK
10 Mark   USA

I would like to show
US: 50%   --> (includes any variation of US ncluding US, U.S., USA, United States)
UK: 30%
CAN: 20%

I've made several attempts myself with no luck. Thanks in advance.

The OLE DB Provider MSDAORA For Linked Server .... Does Not Contain The Table COUNTRY. The Table Either Does Not Exist Or The Current User Does Not Have Permissions On That Table.

Jun 13, 2006

I am using SQL Server 2005 and trying to create a linked server on Oracle 10. I used the commands below:
EXEC sp_addlinkedserver
@server = 'test1',
@srvproduct = 'Oracle',
@provider = 'MSDAORA',
@datasrc = 'testsource'
exec sp_addlinkedsrvlogin
@rmtsrvname = 'test1',
@useself = 'false',
@rmtuser='sp',
@rmtpassword='sp'

When I execute
select * from test1...COUNTRY
I get the error. "The OLE DB provider "MSDAORA" for linked server "...." does not contain the table "COUNTRY". The table either does not exist or the current user does not have permissions on that table."
The 'sp' user I am connecting is the owner of the table. What could be the problem ?
Thanks a lot.

Error: 8624 Internal Query Processor Error: The Query Processor Could Not Produce A Query Plan.

May 24, 2007

SQL Server 2005 9.0.3161 on Win 2k3 R2

I receive the following error:

"Error: 8624, Severity: 16, State: 1 Internal Query Processor Error: The query processor could not produce a query plan. For more information, contact Customer Support Services."

I have traced this to an insert statement that executes as part of a stored procedure.

INSERT INTO ledger (journal__id, account__id,account_recv_info__id,amount)

VALUES (@journal_id, @acct_id, @acct_recv_id, @amount)

There is also an auto-increment column called id. There are FK contraints on all of the columns ending in "__id". I have found that if I remove the contraint on account__id the procedure will execute without error. None of the other constraints seem to make a difference. Of course I don't want to remove this key because it is important to the database integrity and should not be causing problems, but apparently it confuses the optimizer.

Also, the strange thing is that I can get the procedure to execute without error when I run it directly through management studio, but I receive the error when executing from .NET code or anything using ODBC (Access).

SQL Server 2012 :: Adding Count To Query Without Duplicating Original Select Query

Aug 5, 2014

I have the following code.

SELECT _bvSerialMasterFull.SerialNumber, _bvSerialMasterFull.SNStockLink, _bvSerialMasterFull.SNDateLMove, _bvSerialMasterFull.CurrentLoc,
_bvSerialMasterFull.CurrentAccLink, _bvSerialMasterFull.StockCode, _bvSerialMasterFull.CurrentAccount, _bvSerialMasterFull.CurrentLocationDesc,
_bvSerialNumbersFull.SNTxDate, _bvSerialNumbersFull.SNTxReference, _bvSerialNumbersFull.SNTrCodeID, _bvSerialNumbersFull.SNTransType,
_bvSerialNumbersFull.SNWarehouseID, _bvSerialNumbersFull.TransAccount, _bvSerialNumbersFull.TransTypeDesc,

[code]...

However, as you can see, the original select query is run twice and joined together.What I was hoping for is this to be done in the original query without the need to duplicate the original query.

Query Fails With Invalid Column Name But Succeed As Sub-query With Unexpected Results

Sep 22, 2015

-- The 3rd query uses an incorrect column name in a sub-query and succeeds but rows are incorrectly qualified. This is very DANGEROUS!!!
-- The issue exists is in 2008 R2, 2012 and 2014 and is "By Design"

set nocount on
go
if object_id('tempdb.dbo.#t1') IS NOT NULL drop table #t1
if object_id('tempdb.dbo

[code]....

This succeeds when the invalid column name is a valid column name in the outer query. So in this situation the sub-query would fail when run by itself but succeed with an incorrectly applied filter when run as a sub-query. The danger here is that if a SQL Server user runs DML in a production database with such a sub-query which then the results are likely not the expected results with potentially unintended actions applied against the data. how many SQL Server users have had incorrectly applied DML or incorrect query results and don't even know it....?

Why The Query Works In Query Analyser And Doesn't Work In Reporting Service ?

Apr 30, 2007

Hello everybody,

I'm developing a report using the following structure :

declare @sql as nvarchar(4000)

declare @where as nvarchar(2000)

set @sql = 'select ....'

If <conditional1>

begin

set @where = 'some where'

end

If <conditional2>

begin

set @where = 'some where'

end

set @sql = @sql + @where

exec(@sql)

I run it in query analyser and works fine, but when I try to run in Reporting Services, Visual studio stops responding and the cpu reaches 100 %.

I realize that when I cut off the if clauses, then it works at Reporting services.

Does anybody know what is happening?

Why the query works in query analyser and doesn't work in Reporting Service ?

Thanks,

Maurício

SQL Server Admin 2014 :: Estimated Query Plan For A Stored Procedure With Multiple Query Statements

Oct 30, 2015

When viewing an estimated query plan for a stored procedure with multiple query statements, two things stand out to me and I wanted to get confirmation if I'm correct.

1. Under <ParameterList><ColumnReference... does the xml attribute "ParameterCompiledValue" represent the value used when the query plan was generated?

<ParameterList>
<ColumnReference Column="@Measure" ParameterCompiledValue="'all'" />
</ParameterList>
</QueryPlan>
</StmtSimple>

2. Does each query statement that makes up the execution plan for the stored procedure have it's own execution plan? And meaning the stored procedure is made up of multiple query plans that could have been generated at a different time to another part of that stored procedure?

///////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
I executed the code successfully and I got a box which asked for "Enter the query string".
I typed in the following: EXEC dbo.SalesByCategory @Seafood. I got the following box: Query attempt failed. Must declare the scalar variable "@Seafood". I am learning how to enter the string for the "SQL query programed in the subQuery_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnQuery.Click" (see the code statements listed above). Please help and tell me what I missed and what I should put into the query string to get the information of the "Seafood" category out.

Thanks in advance,
Scott Chang

SP To Perform Query Based On Multiple Rows From Another Query's Result Set

Nov 7, 2007

I have two tables .. in one (containing user data, lets call it u).The important fields are:u.userName, u.userID (uniqueidentifier) and u.workgroupID (uniqueidentifier)The second table (w) has fieldsw.delegateID (uniqueidentifier), w.workgroupID (uniqueidentifier) The SP takes the delegateID and I want to gather all the people from table u where any of the workgroupID's for that delegate match in w. one delegateID may be tied to multiple workgroupID's. I know I can create a temporary table (@wgs) and do a: INSERT INTO @wgs SELECT workgroupID from w WHERE delegateID = @delegateIDthat creates a result set with all the workgroupID's .. this may be one, none or multipleI then want to get all u.userName, u.userID FROM u WHERE u.workgroupIDThis query works on an individual workgroupID (using another temp table, @users to aggregate the results was my thought, so that's included)         INSERT INTO @users            SELECT u.userName,u.userID                FROM tableU u               LEFT JOIN tableW w ON w.workgroupID = u.workgroupID               WHERE u.workgroupID = @workGroupIDI'm trying to avoid looping or using a CURSOR for the performance hit (had to kick the development server after one of the cursor attempts yesterday)Essentially what I'm after is:             SELECT u.userName,u.userID
               FROM tableU u
               LEFT JOIN tableW w ON w.workgroupID = u.workgroupID
               WHERE u.workgroupID = (SELECT workgroupID from w WHERE delegateID = @delegateID) ... but that syntax does not work and I haven't found another work around yet.TIA!

Query Designer Encountered A Query Error Via Enterprise Manager

Jan 7, 2002

I am trying to run queries against any of the user tables in my MS SQL 7.0 database. I get a message the Query Designer encountered a query error.
We have tried rebooting the SQL Server and I am still getting these messages. Also, the SQL error logs look fine - all database
maintenance are running successfully including the DBCCs which show no errors. Any help would be greatly appreciated as we are to go
into production in a few days.
