I want to create a web page where a user can select from 1-100 fields to include in output, and then query a table to only return the fields the user has selected.
I do not want to construct a dynamic SQL SELECT statement. I would rather use a stored procedure, but am not certain how to only return the fields that the user selected.
Hey everyone,
I have a question about using Parameters in queries. I created a list of parameters that the user can select from. For example one is MS07%. The other parameter is a list of locations that is built from a query. These parameters are then being used in a query to build a dataset. When i try to preview the report I select parameters the I know work because I tested the query with them, I get an error that says "Must declate the scalar variable "@Param1". I'm not really sure what that means. Any help would be appreciated.
Thank you in advance,
Keith
Hi all,
I have a MDX query that has been put together from a Analysis Services Cube in Reporting Services, as below:
SELECT NON EMPTY { [Measures].[MM Document Count], [Measures].[FI Document Total], [Measures].[MM Document Total], [Measures].[FI Document Count] } ON COLUMNS, NON EMPTY { ([Lookup Company Code].[Company Code].[Company Code].ALLMEMBERS * [Lookup Financial Period].[Financial Year].[Financial Year].ALLMEMBERS * [Lookup Financial Period].[Financial Period].[Financial Period].ALLMEMBERS ) } DIMENSION PROPERTIES MEMBER_CAPTION, MEMBER_UNIQUE_NAME ON ROWS FROM ( SELECT ( STRTOSET(@LookupCompanyCodeCompanyCode, CONSTRAINED) ) ON COLUMNS FROM [SAP Document Analysis Doc Totals MM FI]) CELL PROPERTIES VALUE, BACK_COLOR, FORE_COLOR, FORMATTED_VALUE, FORMAT_STRING, FONT_NAME, FONT_SIZE, FONT_FLAGSIt has a parameters @LookupCompanyCodeCompanyCode, which creates the following dataset query:
WITH MEMBER [Measures].[ParameterCaption] AS '[Lookup Company Code].[Company Code].CURRENTMEMBER.MEMBER_CAPTION' MEMBER [Measures].[ParameterValue] AS '[Lookup Company Code].[Company Code].CURRENTMEMBER.UNIQUENAME' MEMBER [Measures].[ParameterLevel] AS '[Lookup Company Code].[Company Code].CURRENTMEMBER.LEVEL.ORDINAL' SELECT {[Measures].[ParameterCaption], [Measures].[ParameterValue], [Measures].[ParameterLevel]} ON COLUMNS , [Lookup Company Code].[Company Code].ALLMEMBERS ON ROWS FROM [SAP Document Analysis Doc Totals MM FI]
Within the Report Parameters it is set with as being a Multi value parameter and default value for return all records: [Lookup Company Code].[Company Code].[All]
This work fine when previewing report & when I build.
Problem is when I drop a report viewer control in VWD 2005 and attach this report, it does not run with the default values when the page loads.
Does anyone have a idea what I might be doing wrong? or/and how would i pass a value from a listbox extbox to the parameter and then run the report?
Thanks in advance

I have an sql query that has specific criteria (like state='PA' orstate = 'NJ'...) and would like to be able to have the user specifythe criteria dynamically either through the web or from MSAccess oranother tool.The query also does a GROUP BY the state and other variables that arepart of the criteria.I know how to get MSAccess and asp pages to do the sorting andselecting against an SQL tbl or view, but when access queries the sameinfo as the original sql view, the process takes much longer than whenthe sql view does all of the sorting, selecting and grouping..The table we are currently using is 5 million records and will begrowing to 250 million records shortly, so speed is of the essence.The sql views and MSAccess are both running from the same server sothere is no issue at this point of a network impacting the MSAccessquery.Any suggestions...

Though I am a novice to MS SQL server (2000 I believe), I can do almost!everything I need. Maybe not efficiently, but usefully. However, I havea problem -- a complex query problem...I can create a parameter query in a stored procedure, but how do I usethe result set of a parameter query in a select query (in the same oranother sp)? In short, if a select query contains a result table that isgenerated as a parameter query, how do I pass the parameter through theselect query to the nested parameter query?For example, if I have a sp parameter query called [e_typerows], I couldwrite the following select query which uses the (single) result set from[e_typerows] plus other tables or views:SELECT TOP 100 PERCENT bi_occ_01_e.row, bi_occ_01_e.pos,bi_dictionary_e.typestring, bi_occ_01_e.shadowFROM bi_dictionary_e INNER JOIN(bi_occ_01_e INNER JOIN[e_typerows] ON bi_occ_01_e.row = [e_typerows].row) ONbi_dictionary_e.typeid = bi_occ_01_e.typeidORDER BY bi_occ_01_e.row, bi_occ_01_e.posEven though [e_typerows] is a (storted procedure) parameter query thiswill work IF my parameter in [e_typerows] has a default, say "yyyy". Inthe default case no parameter needs passing. But what if it doesn't havea default value or if I need to pass a parameter to it?Is there any way to replace[e_typerows]in the above query with somethinglike [e_typerows @myparameter='xxxx']? (Maybe I should try that! I'veseen nothing about it though.)My parameter query, [e_typerows], looks like this in fact:@typestringparameter varchar(100) = "yyyy"SELECT dbo.bi_dictionary_e.typestring, dbo.bi_occ_01_e.rowFROM dbo.bi_occ_01_e INNER JOINdbo.bi_dictionary_e ONdbo.bi_occ_01_e.typeid = dbo.bi_dictionary_e.typeidGROUP BY dbo.bi_dictionary_e.typestring,dbo.bi_occ_01_e.rowHAVING (dbo.bi_dictionary_e.typestring = @typestringparameter)Any suggestions would be greatly appreciated! (For the moment, I firstgenerate the parameter query result set, then I loop through each row ofthat result set and do a select query with that row as a parameter --very complicated!, though it does work.)

I need to create a stored procedure that will have about 10-15 queries and take 3 parameters.
the variables will be: @lastmonth, @curryear and @id
@lastmonth should inherit Session variable intlastmonth
@curryear should inherit Session variable intCurrYear
@id should inherit Session id
One example query is SELECT hours FROM table WHERE MONTH ='" + Session("intLastmonth") + "' AND YEAR ='" + Session("intCurrYear") + "' AND [NUMBER] = '" + Session("id")
The rest of the queries will be similar and use all 3 variables as well.
How can I go about this and how will queries be seperated.

ASP.NET / VB.NETSQL Server 7.0Our client has insisted that we change our established practice ofbuilding SQL in-line and move it all to SPROCs. Not a problem for 80%of the app. However, we have a number of Search/Filter forms thatcontain a number of controls to allow more or less focused searchcriteria to be built up.I have a class that does this quite nicely, examining all controls forvalid input and, if found, concatenated onto the end of what becomes a"WHERE" clause. Once all is done the "WHERE" clause is appended to aSQL Statement and passed to an ExecuteReader function. Only atruntime is it known how many, and which, controls will be used in thefilter.I can think of two methods of approaching this variable parameter listwhich will be required if moving to SPROCs.METHOD 1.Create a SPROC where ALL the possible parameters are used. Forexample:CREATE PROC stpSearchContactsUsingContactRef@ContactRef varchar(50),@Status varchar(50),@IgnoreDate int,@Date1 smalldatetime,@Date2 smalldatetimeASSELECTtblContactSources.*FROMtblContactsWHERE(tblContacts.fldContactID LIKE @ContactRef) AND(tblStatuses.fldStatus LIKE @Status) AND((tblContacts.fldDateCreated >= @Date1) AND(tblContacts.fldDateCreated <= @Date2) OR @IgnoreDate = 0)GOIf either of the parameters @ContactRef and @Status is empty, the codethat retrieves the filter values passes in the value '%', otherwise itwill pass in the user's choice. If the user wants not to search on thedate range, then @Date1 and @Date2 are passed in with '' and@IgnoreDate is set to 0.METHOD 2.Create a SPROC which consists of SQL body as a string, with the"WHERE" clause passed in as a string parameter, and both EXEC'd -CREATE PROCEDURE stpTSRGetFilteredTSR@WhereClause as varchar(3999)ASDECLARE @Body as varchar(3999)DECLARE @OrderBy as varchar(3999)SET @Body = 'SET CONCAT_NULL_YIELDS_NULL OFFSELECT TOP 100 PERCENTtblTSRs.fldTSRID, tblTSRs.fldFaultDescription,tblTSRs.fldDateEntered, tblTSRPriorities.fldTSRPriority,tblTSRs.fldTSRPriorityID, tblVehicles.fldRegistrationNumber,tblVehicles.fldVIN, tblTSRStatuses.fldTSRStatus,tblTSRs.fldTSRStatusID, tblTSRs.fldDealerID, tblTSRs.fldEmergency,tblCustomers.fldFirstName + '' '' + tblCustomers.fldSurname ASfldCustomerNameFROMtblContactReasonsINNER JOIN tblContacts ON tblContactReasons.fldContactID =tblContacts.fldContactIDINNER JOIN tblCustomers ON tblContactReasons.fldRegardingID =tblCustomers.fldCustomerIDINNER JOIN tblVehicles ON tblContactReasons.fldVehicleID =tblVehicles.fldVehicleIDRIGHT OUTER JOIN tblTSRs WITH (NOLOCK)LEFT OUTER JOIN tblTSRStatuses ON tblTSRs.fldTSRStatusID =tblTSRStatuses.fldTSRStatusIDLEFT OUTER JOIN tblTSRPriorities ON tblTSRs.fldTSRPriorityID =tblTSRPriorities.fldTSRPriorityID ON tblContacts.fldContactID =tblTSRs.fldContactIDWHERE (GETDATE() <= DATEADD(week, 2, tblTSRs.fldDateEntered))'SET @OrderBy = 'ORDER BY tblTSRs.fldDateEntered'SET @Body = @Body + @WhereClause + @OrderByEXEC (@Body)GOIn this example, the @WhereClause parameter might typically be:' AND (fldDealerID = 9) AND (fldTSRStatusID = 1) 'My question is, is there anything to recommend one method over theother?TIAEdward--The reading group's reading group:http://www.bookgroup.org.uk

HiI am new to the world of aspx, .net and C#.In aspx .net 2.0. I am trying to work out how to get a datagrid to perform an update. Using Visual Developer I have successfully added the control and specifed a select statement to return data via my SQLData Source. This works fine. However having specifed the control as editable I would like to perform an update through the datagrid and SQLDatasource. I see in the properties for the SQLDatasource object I can specify my update statement.However I do not understand how to get that update statement to have variable values and how newly entered values from the grid can be placed into these variables when the update takes place. Can someone please point me in the right direction? I have not found the MS doc very illuminating thus far and have not found any examples.Many ThanksT
View 1 Replies View RelatedHello all,I'm writing a site with one page that uses the session variable (User ID) to pick one user ID out of a comma separated list in the field Faculty. The default parameterized query designed in the SqlDataSource wizard only returns lines that contain an exact match:SELECT * FROM tStudents WHERE ([faculty] = @faculty) The query: SELECT * FROM tStudents WHERE ([faculty] LIKE '%userID%') works as I need when I hard code the query with a specific user ID into the SqlDataSource in the aspx page. It will not work if I leave the @faculty parameter in it:SELECT * FROM tStudents WHERE ([faculty] LIKE '%@faculty%') e.Command.Parameters works to replace the @Faculty with a user ID, but again, adding the single quote and percentage sign either causes errors or returns no results. I've tried several variations of: string strEraiderID = "'%" + Session["eRaiderID"].ToString() + "%'"; e.Command.Parameters["@faculty"].Value = strEraiderID;no results are returned, not even the lines returned with the default select query.How do generate the equivalent of SELECT * FROM tStudents WHERE ([faculty] LIKE '%userID%') into the SqlDataSource?

I have received a change request for a project i am working on which im unsure if possible or not.
at the minute i have a very simple sp that simply selects data from a table by passing in one parameter
CREATE PROCEDURE PHAR_SelectGrade
@int_ID int
AS
SELECT GradeID as ID, Grade as Description, RequiresText, SendEmail, Timestamp
FROM tbl8Grade
WHERE Obsolete=0
AND GradeID = @int_ID
ORDER BY Grade
the user now wants the option to select more than one grade type (there are 100's of different grades)
so they might decide they want to see details for 2 grades, 22 grades etc. these would be selected and stored in an array (via an asp.net project) and then the stored procedure is called from within a web service
my question is how would i pass this array into the stored procedure??
i am assuming i would need to do something as follows for sp syntax, but im stumped on how i pass my array of values into the sp from the webservice and then for the sp to read the array in SQL??
CREATE PROCEDURE PHAR_SelectGrade
@myArray <what datatype?>
AS
SELECT GradeID as ID, Grade as Description, RequiresText, SendEmail, Timestamp
FROM tbl8Grade
WHERE Obsolete=0
AND GradeID IN (@myArray)
ORDER BY Grade
any ideas are greatly appreciated. or maybe its just not possible?!?

Hi,
I have a repeater control which I populate with search results from SQL Server.
But I can't figure out how to cope with users who submit multiple search items and still use my stored procedure. Is this possible or do you have to build the query with a StringBuilder and execute it manually?
I'm using a stored procedure with parameters:
input parameters <-- PageSize & CurrentPage
output parameter --> TotalRecords
Am using a temporary table to store all records before Select-ing those required for the particular page.
If I compose the query manually then I can't figure out how to get TotalRecords back as a return parameter. Would appreciate help on this one.
Am hoping that stored procedures can cope with an unknown number of parameters.
I am fairly new to MSSQL. Looking for a answer to a simple question.
I have a application which passes in lot of stuff from the UI into a stored procedure that has to be inserted into a MSSQL 2005 database. All the information that is passed will be spilt into 4 inserts hitting 4 seperate tables. All 4 inserts will be part of a stored procedure that have to be in one TRANSACTION. All but one insert are straight forward.
The structure of this table is something like
PKID
customerID
email address
.....
customerID is not unique and can have n email addresses passed in. Each entry into this table when inserted into, will be passed n addresses (The number of email addresses passed is controlled by the user. It can be from 1..n). Constructing dynamic SQL is not an option. The SP to insert all the data is already in place. Typically I would just create the SP with IN parameters that I will use to insert into tables. In this case I can't do that since the number of email addresses passed is dynamic. My question is what's the best way to design this SP, where n email addresses are passed and each of them will have to be passed into a seperate insert statement? I can think of two ways to this...
Is there a way to create a variable length array as a IN parameter to capture the n email addresses coming in and use them to construct multiple insert statements?
Is it possible to get all the n email addresses as a comma seperated string? I know this is possible, but I am not sure how to parse this string and capture the n email addresses into variables before I construct them into insert statements.
Any other ways to do this? Thanks
SQL Server 2000, ASP.Net 1.1
I've been writing this stuff for a while, and can't seem to come to the
conclusion of how I should be retrieving data and assigning this data
to variables.
Since i'm using SQL Server, I'm convinced that I should be using the
datareaders GetSqlDouble (or whatever) function, but this would mean i
need my local variables to be one of the SQL types. The problem
with that is, that there will have to be lots of conversions done by me
to be able to use a SQL type in my application.
For instance, I have a class where i'm retrieving dates. In order
to retrieve them correctly (Null values included), I need to retrieve
them with GetSqlDateTime(), then when it comes time to display the date
in a table, i must first check for nulls, then convert to a
string. This seems to be very cumbersome. Would I be better
off just using GetDateTime(), and the .ToString method, and ignoring
Sql Types all together?
so, basically, how are you guys using your sql server data? with
the supplied sql types, and doing all of the post-processing work
manually? I feel like i'm having trouble conveying my
issue...hopefully someone knows what i mean....i'd just like some
direction to save trouble in the long run, since i feel like there's
got to be a better way...
Confused!

Hi all, I have the code listed below and feel that it could be run much more efficiently. I run this same code for attrib2, 3, description, etc for a total of 21, so on each postback I am running a total of 21 different connections, i have listed only 3 of them here for the general idea. I run this same code for update and for insert, so 21 times for each of them as well. In fact if someone is adding a customer, after they hit the new customer button, it first runs 21 inserts of blanks for each field, then runs 21 updates for anything they put in fields, on the same records. This is running too slow... any ideas on how I can combine these?? We have 21 different entries for EVERY customer. The Pf_property does not change, it is 21 different set entries, the only one that changes is the Pf_Value.

Hey people
I'd be really grateful if someone can help me with this. Could someone explain the following:
If the following code is executed, it runs instantly:
declare @SellItemID numeric (8,0)
select @SellItemID = 5296979
SELECT distinct s.sell_itm_id
FROM stor_sell_itm s
WHERE (s.sell_itm_id = @SellItemID )
However, if I use this WHERE clause instead -
WHERE (@SellItemID = 0 OR s.sell_itm_id = @SellItemID)
- it takes 70 micro seconds. When I join a few more tables into the statement, the difference is 4 seconds!
This is an example of a technique I'm using in loads of places - I only want the statement to return all records if the filter is zero, otherwise the matching record only. I think that by using checking the value of the variable in the WHERE clause, a table scan is used instead of an index. This seems nonsensical since the variable is effectively a constant. Wrapping the entire select statement with an IF or CASE works, but when I've got 10 filters I'd have to 100 select statements.
I DON'T GET IT!! There must be a simple answer, HELP!!

I have found one easy and more efficient way to achieve the same thing.
First I have a table called test with 2 columns (ID and Data)
And some data inserted into it.
CREATE FUNCTION [dbo].CombineData(@ID SMALLINT)

SELECT @Data = @Data + Data + ',' FROM Test WHERE ID = @ID

Then used a simple select query to achieve the same
SELECT DISTINCT ID, [dbo].CombineData(ID) FROM Test
Which achieved the same thing without using any temporary tables and Cursors. I am sure that you will accept that this is more efficient than the one that has been published.

We have MS SQL 2000.On the source data i run a job with the following steps:1> take trans backup every 4 hrs2> ftp to the remote server3> if ftp fails , disable the whole jobOn the target server I run a job which does the following1> restore the trans backup with NORECOVERY.If the job fails at target. I will have to go through the whole processof doing a complete backup of the source , restoring it at the otherens and then starting trans-backup again.Also, if we do a failover to the target server, then when we roll backto the source server again we have to da a back-up of the target andrestore it on the source server.Is ther a more efficent way of doing this??

View 8 Replies View RelatedIt seems I should be able to do 1 select and both return thatrecordset and be able to set a variable from that recordset.eg.Declare @refid intSelect t.* from mytable as t --return the recordsetSet @refid = t.refidthe above doesn't work-how can I do it without making a second trip tothe database?Thanks,Rick
View 3 Replies View RelatedI have two tables JDECurrencyRates and JDE Currency Conversion
I want to insert all the records all the records from JDECurrencyRates to JDECurrencyConversion that does not exists in JDECurrencyConversion table. For matching I am to use three keys i.e. FromCurrency, TO Currency and Effdate
To achieve this task i wrote the following query
INSERT INTO PresentationEurope.dbo.JDECurrencyConversion(Date,FromCurrency,FromCurrencyDesc,
ToCurrency, ToCurrencyDesc, EffDate, FromExchRate, ToExchRate,CreationDatetime
,ChangeDatetime)
(SELECT effdate as date, FromCurrency, FromCurrencyDesc, ToCurrency, ToCurrencyDesc, EffDate,
FromExchRate, ToExchRate, GETDATE(),GETDATE() FROM MAINTENANCE.DBO.JDECURRENCYRATES
WHERE FROMCURRENCY NOT IN (SELECT FromCurrency FROM PRESENTATIONEUROPE.DBO.JDECURRENCYCONVERSION)
OR TOCURRENCY NOT IN (SELECT TOCURRENCY FROM PRESENTATIONEUROPE.DBO.JDECURRENCYCONVERSION)
OR EFFDATE NOT IN (SELECT EFFDATE FROM PRESENTATIONEUROPE.DBO.JDECURRENCYCONVERSION))
Can any one suggest me the better way to accomplish this task or this query is OK (or efficient enough)
I have a number of tables, and I need to create a summary of the data.Now I have two choices. I could create a stored procedure that creates a temp table with the filters applied. This would require 12 selects for each year (we have 3 years of data so far). This means 36 selects so far that fill a temp table.The second choice is to create a table with the required columns and rows. As I am esspecially cross-joining 4 tables, the table would have about 10 x 10 x 12 x A rows, where A is a variable that will grow quickly. I can then keep this table up-to-date using triggers for each insert. Then all I need to do is use an aggregate funtion on the relevant filter.My question is, which is more efficient. Creating a stored procedure that creates the table dynamically, or have a table with thousands of rows and using an aggregate function on these.PS I am using SQL Server 2000Jag
View 1 Replies View RelatedMy e-commerce site is currently running the following process when items are shipped from the manufacturer:1. Manufacturer sends a 2-column CSV to the retailer containing an Order Number and its Shipping Tracking Number.2. Through the web admin panel I've built, a retail staff member uploads the CSV to the server.3. In code, the CSV is parsed. The tracking number is saved to the database attached to the Order Number.4. After a tracking # is saved, each item in that order has its status updated to Shipped.5. The customer is sent an email using ASPEmail from Persits which contains their tracking #.The process seems to work without a problem so long as the CSV contains roughly 50 tracking #'s or so. The retailer has gotten insanely busy and wants to upload 3 or 4 thousand tracking #'s in a single CSV, but the process times out, even with large server timeout values being set in code. Is there a way to streamline the process to make this work more efficiently? I can provide the code if that helps.
