Seek In A SQL Table From Access
Dec 20, 2006I have an MS Access 2003 database from which I want to seek a specific record in a SQL Server Express 2005 database. I can connect to the table and get a recordcount but the recordset.supports (adseek) and recordset.Supports(adIndex) both return false. Any suggestions? Specific code I'm using is as follows:
Dim cnxn As ADODB.Connection
Dim strCnxn As String
Set cnxn = New ADODB.Connection
cnxn.Provider = "sqloledb"
strCnxn = "Data Source=SERVERSQLEXPRESS2005;Initial Catalog=RAMPSQL;Integrated Security='SSPI';"
cnxn.Open strCnxn
Set rsWSC = New ADODB.Recordset
rsWSC.CursorLocation = adUseServer
strSQL = "DailyData"
rsWSC.Open strSQL, cnxn, adOpenKeyset, adLockReadOnly, adCmdTableDirect
Thank you!
Seek Table Column In Stored Procedure
Dec 13, 2007Hi All,
The script below may be use to find out what stored procedure uses a specified column from any of the table. This could be helpful in cases you have change a field name of a table and want to find out what stored procedure uses that column.
create procedure seek_sp_for_columns
@colname_para varchar(500)
as
begin
create table #temp_t
(
textcol varchar(1000)
)
create table #temp_t2
(
procname varchar(500)
)
declare @procname as varchar(500)
declare @found as int
declare @colname as varchar(500)
declare @valid_colname as int
select @valid_colname = count(id)
from syscolumns
where name = @colname_para
if (@valid_colname > 1)
begin
set @colname = '%' + @colname_para + '%'
declare sp_cursor cursor
for select name
from sysobjects
where xtype = 'P'
open sp_cursor
fetch next from sp_cursor
into @procname
while @@fetch_status = 0
begin
insert into #temp_t
exec sp_helptext @procname
set @found = 0
select @found = count(textcol)
from #temp_t
where textcol like @colname
if (@found > 0)
begin
insert #temp_t2 values(@procname)
end
delete #temp_t
fetch next from sp_cursor
into @procname
end
close sp_cursor
deallocate sp_cursor
select *
from #temp_t2
drop table #temp_t
drop table #temp_t2
end
else
begin
select 'Please verify column name'
end
end
Seek Method, Table-direct, And Sql Server2005
Jul 23, 2005From what I've read in the docs, ado.net currently supports opening sqlserver ce tables in table-direct mode and performing Seek operations on them(using SqlCeDataReader), but not on the full-blown sql server. Is this(will this be) still true with ado.net 2.0 & sql server 2005?
View 11 Replies View RelatedSQL Server 2014 :: Memory-optimized Queries Using Table Scan Instead Of Seek?
Sep 19, 2015I've been having some trouble getting a single-column "varchar(5)" field to reliably use a table seek instead of a table scan. The production table in this case contains 25 million rows. As impressive as it is to scan 25 million rows in 35 seconds, the query should run much faster.
Here's a partial table description:
CREATE TABLE [dbo].[Summaries_MO]
(
[SummaryId] [int] IDENTITY(1,1) NOT NULL,
[zipcode] [char](5) COLLATE Latin1_General_100_BIN2 NOT NULL,
[Golf] [bit] NULL,
[Homeowner] [bit] NULL,
[Code] .....
Typically, this table is accessed with a query that includes:
SELECT ...
FROM SummaryTable
WHERE ixZIP IN (SELECT ZipCode FROM @ZipCodesForMO)
This query insists on using a table scan. I've tried WITH (FORCESEEK) for example, but that just makes the query fail.
As I've investigated this issue I also tried:
SELECT * FROM Summaries WHERE ZipCode IN ('xxxxx', 'xxxxx', 'xxxxx')
When I run this query with 64 or fewer (actual, valid) ZIP codes, the query uses a table seek.But when I give it 65 or more ZIP codes it uses a table scan.
To summarize, the production query always uses a table scan, and when I specify 65 or more ZIP codes the query also uses a table scan. I'm wondering if the data type of the indexed column (Latin1_General_100_BIN2) is somehow the problem. I'll likely try converting the ZIP codes to an integer to see what happens.

IRowsetIndex()::Seek In SQL CE
Jul 30, 2007Dear All,
I'm working in eVC++3.0 with SQL CE2.0.
I've developed the application to fetch the data from the mdf file by passing the index field and using the command IRowsetIndex()::Seek.
Consider TableExample with Columns A,B,C,D and index Index1 with column A and Index2 with column B,C,D.
Its working fine when index1 is passed for the indexvalue.But when i pass index2 of the same table,its throwing the error as BADINDEX.
I'm passing the correct keyvalues in the Seek command also.
Kindly help me in this regard.
Regards,
Sasi.
How To Get Index Seek
May 7, 2008Hi,
Can I use index seek and still keep 'like' 'or' functionality for the following statement?
--prepare test table
create table entity (Id int identity(1,1), FamName varchar(200), LastName varchar(200))
go
create clustered index entity_id on entity (id)
go
create nonclustered index entity_lastName on entity (lastName)
go
insert into entity select famName,FirstName from table
--test index
declare @LastName varchar(10)
set @LastName = 'a'
select FamName
from entity
where @LastName is null or LastName like @LastName --clustered index scan
Index Seek Vs Scan
Nov 4, 2002I have created a nolock view off a table to prevent locks. I have users coming in through MS Access that have switched their queries to run against the views. Now we are noticing that queries that used to run as a clustered index seek against the table are running as a clustered index scan against the table and performance in the queries has dropped.
Is there any way that the same query that hits the view instead of the table can be made to run faster or at least use the index seek?
Thanks,
Steve

Seek Help To Understand The Jet Database Engine
Oct 4, 2007Hi,
I am reading the book by Steven Roman:
"Access Database : Design and Programming" 3rd edition.
On page 120, Figure 7-2, he showed the the structure of the Jet Database Engine, which is very confusing to me.
According to this picture, I come to such an understanding:
1) VBA is just the hosting language for the Jet Database Engine;
2) Microsoft Visual Basic, Excel, Access, Word are hosting languages for VBA.
Isn't this weird? VB hosts VBA?
Thanks for any input!
Optimize Query - How To Make It An Index Seek
Jun 21, 2004create table t1(a varchar(50) , b varchar(50))
create index i1 on t1(a)
create index i2 on t1(b)
create view v1
as
select * from t1 where isnull(a,b) = 'test'
select * from v1
The above SQL "select * from v1" is doing a table scan.
What do I do to make it perform an index seek ????
TIA

View 3 Replies View RelatedSQL Server 2012 :: Join To Find All Records From One Table That Do Not Exist In Other Table
Apr 29, 2014I have table 'stores' that has 3 columns (storeid, article, doc), I have a second table 'allstores' that has 3 columns(storeid(always 'ALL'), article, doc). The stores table's storeid column will have a stores id, then will have multiple articles, and docs. The 'allstores' table will have 'all' in the store for every article and doc combination. This table is like the master lookup table for all possible article and doc combinations. The 'stores' table will have the actual article and doc per storeid.
What I am wanting to pull is all article, doc combinations that exist in the 'allstores' table, but do not exist in the 'stores' table, per storeid. So if the article/doc combination exists in the 'allstores' table and in the 'stores' table for storeid of 50 does not use that combination, but store 51 does, I want the output of storeid 50, and what combination does not exist for that storeid. I will try this example:
'allstores' 'Stores'
storeid doc article storeid doc article
ALL 0010 001 101 0010 001
ALL 0010 002 101 0010 002
ALL 0011 001 102 0011 002
ALL 0011 002
So I want the query to pull the one from 'allstores' that does not exist in 'stores' which in this case would the 3rd record "ALL 0011 001".

How To Find Max From A Table By Row
Jul 23, 2005I have a Product table with the columnsAcctNumProdCodeInvoiceDateI can have multiple rows for a given AcctNum:123 A 01/01/2005123 B 01/02/2005123 C 01/03/2005234 C 02/01/2004345 A 01/01/2005345 B 01/02/2005I need the max(InvoiceDate) and if the max for a given AcctNum is a ProdCode= B. So if the latest InvoiceDate is for a given AcctNum is B then returnthat row.123 B 01/02/2005Would not be returned because the max Invoice date for AcctNum 123 isProdCode C.345 B 01/02/2005Would be returned because the max Invoice date for AcctNum 345 is ProdCodeB.I can solve this using a cursor fairly easily by using a distinct AcctNum inthe cursor select and getting the max InvoiceDate for each AcctNum. This isa costly and I'm looking for a solution using temp tables or a query tohandle this problem.I hope I have made this clear enough (sorry if I was too verbose). Thanks inadvance for your help.-p

from sys.tables mtable, sys.all_columns mcolumn, sys.types mtype
where mcolumn.object_id = mtable.object_id
and mcolumn.system_type_id = mtype.system_type_id

But there is no PK information.
Follwing sql statement shows the PK name of a table, but no composite info(which fields):

How To Find An Inserted Value In A Table
Apr 19, 2006Hello,
I have 2 tables, and use objectdatasource and stored procedures, with sql server.
Let say in the first table I have IDCustomer as a datakey, and other records, and in the second I have the same IDCustomer and CustomerName. I have an INSERT stored procedure that will create a new record in the first table (so generate a new IDCustomer value), and I would like to insert immediately this new value in the second table.
How can I know the value of this new IDCustomer ? What is the best way to handle that ? Once the insert in the first table is done should read it the table and extract (with an executescalar) the value and then insert it in the second table ? This solution should work but I am not sure this is the best one.
Thanks for your help.
How To: Find Cols In A Table
Jan 12, 2002I'd like to know if I can make one proc/cursor that I can pass only a table name and it will determine what cols exist in the table?
AND, what is the syntax for such a query?
I will be receiving data back where I will receive the accountID and only the deltas will have values all other columns will be null.
My proc will update an existing record, updating the specific col when an accountID exists, it will create a new record if the accountID does not exist.
I'd like to search all the cols getting their names and values when not null.
I can construct a proc for each table searching each col by known name.
However, I'd like to know if I can make one proc/cursor that I can pass only a table name and it will determine the cols?
All my tables start with cols AccountID and end with RecID with any number of cols inbetween.
TIA
