Parameterized Pass-through Queries From Access Front-end?
Jul 23, 2005Is there any easy way to pass (dynamically) parameters to pass-through
queries,
when working with MS Access as front-end for SQL Server ?
Thanks.

Parameterized Queries - Works In Access But Not SQLS2k?
Feb 3, 2004I have an application where users can enter data into any (or all) of 6 search fields,
to produce a filtered query.
This works fine using my Access version(see code below),
but as SQLS2k cannot use "IIF", I tried to replace these bits with
"CASE/WHEN/THEN/ELSE" lines, which does not work with numeric fields
as these cannot be "wild-carded" in the same way as Access allows.
Can anyone suggest a way forward that does not involve coding all the
possible permutations of "SELECT" blocks driven by lots of nested "IF/THEN/ELSE"s?
Hoping you can help

Parameterized Queries Running Slower Than Non-parameterized Queries
Jul 20, 2005HelloWhen I use a PreparedStatement (in jdbc) with the following query:SELECT store_groups_idFROM store_groupsWHERE store_groups_id IS NOT NULLAND type = ?ORDER BY group_nameIt takes a significantly longer time to run (the time it takes forexecuteQuery() to return ) than if I useSELECT store_groups_idFROM store_groupsWHERE store_groups_id IS NOT NULLAND type = 'M'ORDER BY group_nameAfter tracing the problem down, it appears that this is not preciselya java issue, but rather has to do with the underlying cost of runningparameterized queries.When I open up MS Enterprise Manager and type the same query in - italso takes far longer for the parameterized query to run when I usethe version of the query with bind (?) parameters.This only happens when the table in question is large - I am seeingthis behaviour for a table with > 1,000,000 records. It doesn't makesense to me why a parameterized query would run SLOWER than acompletely ad-hoc query when it is supposed to be more efficient.Furthermore, if one were to say that the reason for this behaviour isthat the query is first getting compliled and then the parameters aregetting sent over - thus resulting in a longer percieved executiontime - I would respond that if this were the case then A) it shouldn'tbe any different if it were run against a large or small table B) thisperformance hit should only be experienced the first time that thequery is run C) the performance hit should only be 2x the time for thenon-parameterized query takes to run - the difference in response timeis more like 4-10 times the time it takes for the non parameterizedversion to run!!!Is this a sql-server specific problem or something that would pertainto other databases as well? I there something about the coorect use ofbind parameters that I overall don't understand?If I can provide some hints in Java then this would be great..otherwise, do I need to turn/off certain settings on the databaseitself?If nothing else works, I will have to either find or write a wrapperaround the Statement object that acts like a prepared statement but inreality sends regular Statement objects to the JDBC driver. I wouldthen put some inteligence in the database layer for deciding whetherto use this special -hack- object or a regular prepared statementdepending on the expected overhead. (Obviously this logic would onlybe written in once place.. etc.. IoC.. ) HOWEVER, I would desperatelywant to avoid doing this.Please help :)

Parameterized Queries
Feb 15, 2007Just getting started using SSce and having a few problems
What I want to do is something like this...
Dim Code As Integer
Dim Description As String = txtDescription.Text.Trim
Dim conn As SqlCeConnection = ConnectToLocalDatabase()
Dim ssql As New System.Text.StringBuilder
ssql.AppendLine("INSERT INTO T_Titles (Description)")
ssql.AppendLine("VALUES(@Description)")
ssql.AppendLine("SELECT @Code = @@IDENTITY")
Dim cmd As New SqlCeCommand(ssql.ToString, conn)
Dim sqlCode As New SqlCeParameter("@Code", 0)
sqlCode.Direction = ParameterDirection.InputOutput
cmd.Parameters.Add(sqlCode)
cmd.Parameters.Add(New SqlCeParameter("@Description", Description))
cmd.ExecuteNonQuery()
Code = CInt(sqlCode.Value)
**********************************************************************
The above code doesnt work. Firstly I am not sure if I can execute the two statements in one go. Secondly, I am not sure if output parameters are supported.
I have been working with SQL Server since 6.5 but have always used sprocs and am feeling a little lost here without them. Any help getting started would be greatly appreciated.
Thanks
If/then Parameterized Queries Using Tableadapter
Jun 29, 2007Hey fellas. Here's my situation. I have two textboxes where the user enters a "start" date and an "end" date. I want to search a table to find records who's "expired" column date is between those two dates provided by the user. The tricky part is, if the user just puts a start date in but no end date, I want it to search from whatever start date the user entered to the future and beyond. Essentially, I think I'm looking for a SQL statement along the lines of:
SELECT Request.RequestID, Request.URL, ActionProvider.Name, Request.CurrentStageID, Request.Decision, Request.SubmissionDate,
Request.ExpirationDate
FROM Request INNER JOIN
RequestSpecificActionProvider ON Request.RequestID = RequestSpecificActionProvider.RequestID INNER JOIN
ActionProvider ON RequestSpecificActionProvider.ActionProviderID = ActionProvider.ActionProviderID INNER JOIN
RoleActionProvider ON ActionProvider.ActionProviderID = RoleActionProvider.ActionProviderID INNER JOIN
Role ON RoleActionProvider.RoleID = Role.RoleID
WHERE
CASE WHEN @BeginDate is not null AND @BeginDate <> ''
THEN Request.ExpirationDate > @BeginDate
END
AND
CASE WHEN @EndDate is not null AND @EndDate <> ''
THEN Request.ExpirationDate > @EndDate
END
AND (Role.Description = 'Requestor')
I realize my code isn't correct and there's still a floating "AND" out there I would have to put some logic around. Anyway, how do I do this? Do I need to build three separate queries in my tableadapter (one for if both dates are provided, one for if start date is provided, one for if end date is provided) and build the logic in my application code or can I tackle it with SQL? If I can tackle it with SQL, where have I gone astray? I'm currently getting the error: "Error in WHERE clause near '>'. Unable to parse query text."
Thanks for the help everyone!
Debugging Parameterized Queries

I have a sqlCommand to which I add several parameters for an insert statement.

Urgent Urgent Please.(Access SQL Pass Through Queries)
Jul 6, 2000Hello,
I am facing a huge problem in my sql server database using access as a front end.The main problem is trying to execute queries "views" ,since they reside on sql server now,and using variables or parameters in reports and forms to filter on this query.
Ex.
how can the following be implemented using the same query but in sql server?
Access
------
SELECT MAT_Charts.YYYYMM
FROM MAT_Charts
WHERE ((([Area_Code] & "-" & [GROUP_CODE])=[Reports]![MAT_Chart_C1].[MAT_Key]))
GROUP BY MAT_Charts.YYYYMM;
It is specifically this statement in which I am interested:
[GROUP_CODE])=[Reports]![MAT_Chart_C1].[MAT_Key]))
Thank you very much for your concern.
SQL Stored Procedure Can't Insert , Parameterized Queries...
May 16, 2004I have a SQL stored procedure like so:
CREATE PROCEDURE sp_PRO
@cat_num nvarchar (10) ,
@descr nvarchar (200) ,
@price DECIMAL(12,2) ,
@products_ID bigint
AS
insert into product_items (cat_num, descr, price, products_ID) values (@cat_num, @descr, @price, @products_ID)
when I try and insert something like sp_PRO '123154', 'it's good', '23.23', 1
I can't insert "'" and "," because that is specific to how each item is delimited inorder to insert into the stored procedure. But if I hard code this into a aspx page and don't create a stored procedure I can insert "'" and ",". I have a scenario where I have to use a stored procedure...confused.
SQL Server 2005 Driver For PHP - Parameterized Queries
Mar 14, 2008I've setup a parameterised query in PHP correctly and achieved the results I wanted from a basic view.
I then developed the application to use a Table-valued Function to be able to simplify the PHP code.
SELECT * FROM [CDBF].[dbo].[webOrganisation] ('w%',5,11)
This query works fine within the code.
/* Define the query. */
$tsql = "SELECT * FROM webOrganisation ('w%',5,11)";
/* Execute the query. */
$stmt = sqlsrv_query( $connection, $tsql);
if ( ! $stmt )
{
echo "Error in statement 2 execution in display_search().";
die( print_r( sqlsrv_errors(), true));
}
/* Iterate through the resultset printing a row of data upon each iteration.*/
while( $row = sqlsrv_fetch_array( $stmt, SQLSRV_FETCH_ASSOC))
{
// Display results (this bit works fine!)
}
/* Free statement and connection resources. */
sqlsrv_free_stmt( $stmt);
However when I try to parameterise it, I get errors.
Error in statement 2 execution in display_search(). Array ( [0] => Array ( [0] => 07009 [SQLSTATE] => 07009 [1] => 0 [code] => 0 [2] => [Microsoft][SQL Native Client]Invalid Descriptor Index [message] => [Microsoft][SQL Native Client]Invalid Descriptor Index ) [1] => Array ( [0] => 07009 [SQLSTATE] => 07009 [1] => 0 [code] => 0 [2] => [Microsoft][SQL Native Client]Invalid parameter number [message] => [Microsoft][SQL Native Client]Invalid parameter number ) )
/* Define the query. */
$tsql = "SELECT * FROM webOrganisation ( ? , ? , ? )";
/* Execute the query. */
$start = 5;
$finish = 11;
$params = array($search.'%',$start,$finish);
$stmt = sqlsrv_query( $connection, $tsql, $params);
if ( ! $stmt )
All other parts of the code remain the same.
Where am I going wrong

SQL Server, Full Text Indexing, And ASP.NET Parameterized Queries
Aug 12, 2006I've been driving myself nuts trying to get a sensible product search
going. The existing live site search is just a LIKE %searchterm% on
the Title field in our Products table. Fast, but not great ;) Talks
between IT and Marketing have resulted in this being the desired
results and order:
Exact Title match
Substring Title match
Substring Keywords match
Substring Description match
OK, I can easily do this with UNION queries using LIKE (and a virtual
"weight" column in each query), but the query takes too long. So I'm
trying out SQL Server full text indexing, in an attempt to get the
speed up (and the natural language stuff is just plain cool).
Where I'm running into problems is doing a FULLTEXT match on
Description. It seems that to do a phrase match (e.g. "new york"
should match only Descriptions where the phrase "new york" occurs) I
need to enclose the search term in quotation marks in the query (or
maybe single AND double quotes).
But using parameters in ASP.NET (which I'm supposed to do to avoid SQL
injection attacks, yes?) I don't really have full control of the
quoting - ASP.NET and/or SQL Server automagically quotes strings for
me before passing them into the query. I think.
For example, this doesn't find any description matches:
==========================================
Declare @theSearchTerm varchar(100), @theSearchTerm1 varchar(100)
set @theSearchTerm = "new york"
set @theSearchTerm1 = "%new york%"
SELECT m.TitleCode, m.ShortName, m.ShortDescription, 50 as theWeight
FROM Product m(NoLock)
WHERE m.ShortName = @theSearchTerm
UNION
(SELECT m.TitleCode, m.ShortName, m.ShortDescription, 40 as theWeight
FROM Product m(NoLock)
WHERE m.ShortName LIKE @theSearchTerm1)
UNION
(SELECT m.TitleCode, m.ShortName, m.ShortDescription, 30 as theWeight
FROM Product m(NoLock)
WHERE CONTAINS(*, '"@theSearchTerm"'))
ORDER BY theWeight DESC, m.ShortName
==========================================
But this one (where I put in the actual string instead of using the
parameter) *does* get the desired results, including matches in the
Description:
==========================================
Declare @theSearchTerm varchar(100), @theSearchTerm1 varchar(100)
set @theSearchTerm = "new york"
set @theSearchTerm1 = "%new york%"
SELECT m.TitleCode, m.ShortName, m.ShortDescription, 50 as theWeight
FROM Product m(NoLock)
WHERE m.ShortName = @theSearchTerm
UNION
(SELECT m.TitleCode, m.ShortName, m.ShortDescription, 40 as theWeight
FROM Product m(NoLock)
WHERE m.ShortName LIKE @theSearchTerm1)
UNION
(SELECT m.TitleCode, m.ShortName, m.ShortDescription, 30 as theWeight
FROM Product m(NoLock)
WHERE CONTAINS(*, '"new york"'))
ORDER BY theWeight DESC, m.ShortName
==========================================
Trying various permutations of quotes around the parameter gives me
either syntax errors or undesirable results.
Has anybody tried this sort of thing? How did you do it?
Thanks,
Greg Holmes

SQL 7 Security And Access 97 Front End
Jan 26, 2001I am using Access 97 as a front end to access SQL 7 server on NT 4.0 server.
I've set up security model based on NT authentication only. Users have login right to login to SQL and they have public & dataread & denydatawrite access. They also have SELECT permission on a table object and have no permission to INSERT, DELETE and UPDATE.
When I use Access 97 to access a database, users are still capable of inserting and deleteing records in tables.
Am I doing something wrong?
Thanks, Michael.
VB Vs Access As A Front End To SQL, Oracle, Etc
Jan 18, 1999Maybe because I have worked mainly with VB as a front end to SQL Server so I am biased, but I now need definite reasons (I am on a committee for potential future directions) for using VB as opposed to Access for front ending SQL/Oracle, etc. I would also like to use ADO as oppose to DAO. Right now we are using Access with DAO.
Any ideas greatly appreciated.
Access Front End Crawls
Oct 10, 2001Hi,
We have just moved a largish Access database (180mb, 78 tables, largest
tables have about 250k records) to SQL 2k. The original app had an Access
back end (now loaded to SQL), and an Access front end (on each client) which is using some
local temporary tables, about 600 queries, and several thousand lines of
code using ADO and DAO). The Front end was relinked to SQL back end. When
testing everything seemed to run OK, but under load (15-20 users) the new
app just crawls. Routines that used to take seconds now take 10s of minutes.
ODBC timeouts or blocks are common.
Any idea why should the SQL back end be so much slower than Access. both the
Access back end and SQL2k are on the same server (Win 2k Adv. with RAID 5,
dual 600mhz Pent III, 512Mb RAM).
I realize that Access is not the best front end but that is what we have to work with.
Any help would be appreciated, as I am ready to swith back to Access.
Thanks,
Jakub
Front End Options (access)
Oct 27, 2006My company uses MS SQL Server for the back end and a Retail specific CRM as the front end. I wish to develop some internal peices of software for our use. I was planning on doing this with access.
my options are:
*Use access as front end and backend
*Use access as front end and SQL server as backend (create new DB)
*Use other front end and SQL Server as backend.
My question is, what are some good front ends that are availble for reletively small demands? How does Visual Studio come into play?
*Also, I would prefer to be able to create a .exe. I dont think access alows that. I would not want users to be able to go in (or even see) the tables and queries. They should only be able to see the one main menu form at the very least.
thankyou,

Access Front-end/ SQL Backend -- Where Is All The Work Done?
Apr 18, 2001If I'm using an Access front-end, and the data is on SQL Server being accesses via a linked table, and I create a query in Access, Where is all the work done?
I know access has the option of using a pass-through method, but if I do not use it, is Access processing the query locally? I plan on migrating several tables to SQL because the sizes are getting to large for Access and want to know if their will be a performance increase with out re-writing the queries in Access.

Using SQL Server CE As A Back-end To An MS Access Front-end
Mar 2, 2007I have a back-end front-end application in MS Access. Instead of using MS Access queries it gets data via recordsets generated from SQL scripts in VBA routines.
I'm planning to upgrade it to use SQL Server as the back-end. However I need to retain the alternative option of using a file based back-end. (It currently has the capacity to be switched between alternative Access .mdb back-end files.) Is there any information available on how to do this and on how to get Access to synchronize between SQL Server and SQL Server CE back-ends? (Eventually the application will be migrated to VB.NET, but that is a long way down the track.)
