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.
HelloWhen 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 :)
I would like to know what are the ways to call a parameterized stored procedure within a loop in ASP.NET. Scenario: I have a loop through a dataSet and for each record I am going to execute a stored procedure to insert data in many tables. I can not use the following syntax: cmd.CommandType = CommandType.StoredProcedure cmd.CommandText = "dbo.storedprocedurename" With cmd .Parameters.Add(New SqlClient.SqlParameter("@param1", paramValue1)) .Parameters.Add(New SqlClient.SqlParameter("@param2", paramValue2)) End With What are the other ways to execute the parameterized stored procedures within a loop in ASP.NET?
but in this case, I would want to pass the values from a couple of cells in the worksheet. Do I have to use ADO (so this isn't a SQL Server question at all?)
I'm trying to build ssis package that select rows from SQL Server table and
according to Conditional Split cube results I should execute oracle stored

The in parameters should come from the SQL select and the output parameters

Is there a way to use parameterized queries with RDA method? I write a program for WinCE5.0 and when I submit a query I use hardcoded date format and this causes problems in different systems.There's a solution for this?
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.
Hey 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!
How would I debug such a query. I have a sqlCommand to which I add several parameters for an insert statement. if the statement fails, for some reason, I would like to copy the final sql with all values inserted as text and use this in e.g. TOAD to see where the error is coming from. Is this possible?
Hi, I need to use parameters with the IN clause in a SQL statement like: select * from tableX where field IN (1,2,3,4) I don't know how to do that. I'm using SQLServer and OleDB.
I 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?
FROM (((tAudit LEFT JOIN tCategories ON tAudit.CategoryID = tCategories.CategoryID) LEFT JOIN tClients ON tAudit.ClientID = tClients.ClientID) LEFT JOIN tContracts ON tAudit.ContractID = tContracts.ContractID) LEFT JOIN tProducts ON tAudit.ProductID = tProducts.ProductID
WHERE (((tAudit.ActionType) Like IIf(IsNull([CurrentType]),"*",[CurrentType])) AND ((tAudit.ClientID) Like IIf(IsNull([CurrentClientID]),"*",[CurrentClientID])) AND ((tAudit.ContractID) Like IIf(IsNull([CurrentContractID]),"*",[CurrentContractID])) AND ((tAudit.ProductID) Like IIf(IsNull([CurrentProductID]),"*",[CurrentProductID])) AND ((tAudit.CategoryID) Like IIf(IsNull([CurrentCategoryID]),"*",[CurrentCategoryID])) AND (([tAudit].[DateStamp]) Between [FromDate] And [ToDate]));
know if there is any way out to run execution plan for parameterized queries?
As application is sending queries which are mostly parameterized in nature and values being used are very robust in nature, So i can not even make a guess.
I'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?
Hi ya'll! First off, please let me know if I'm totally doing the wrong thing here ...
I have set up two different simple queries in one stored procedure that I'd like to reference from one fetch from my ASP.Net/VB.Net web template. Can I do this? I think I can, 'cause most of the data is showing up.
Code follows: [stored procedure]
CREATE PROCEDURE dbo.sp_admin_vStatistics AS BEGIN
SELECT COUNT(metric_ID) AS device_totalRequests, MAX(request_due_date) AS device_maxRequest_due_date, MIN(request_due_date) AS device_minRequest_due_date, MAX(metric_log_dtTime) AS device_maxLog_dtTime, FROM dbo.metrics
SELECT COUNT(user_ID) AS user_total, MAX(user_lastlogin_dtTime) AS user_LastLogin FROM dbo.users
END GO
[snippet of .Net page where I'm actually trying to display the output]
'Loop over our query results & print it Do While (dr.Read()) lblUser_Total.Text = CType(dr("user_total"), Integer) lblUser_LastLogin.Text = CType(dr("user_LastLogin"), Date) lblDevice_TotalRequests.Text = CType(dr("device_totalRequests"), Integer) lblDevice_minRequest_due_date.Text = CType(dr("device_minRequest_due_date"), Date) lblDevice_maxRequest_due_date.Text = CType(dr("device_maxRequest_due_date"), Date) lblDevice_minLog_dtTime.Text = CType(dr("device_minLog_dtTime"), Date)
Loop
My output shows nothing for user_total and user_lastlogin, but the other "device" information gets properly displayed. Running SQL Query Analyzer shows it all. I just think I'm referencing it incorrectly.
I am trying to create a stored procedure to be called from an ASP.Net page.
There are two sets of stats that I want to be able to pull off for a given ID - firstly a list of all the names given and the number of times that name has been given and secondly a list of all the reasons given and the number of times for each reason.
With the queries there is clearly different Group By required to get the necessary stats off.
I dont want to have to make two round trips to the server to get the two different results but cannot see how to otherwise to get the results out and into ASP.Net to consume?
Hi all,Sorry for HTML, there is a lot of code & comments I tried to create a stored procedure from 3 queries .. to reduce # of times DB gets access from 1 asp page. The result procedure only works 1/2 way (does return the rest of the SELECT statement) :( Please help me figure out what stops it mid way? I need it to return all the results from the SELECT statements AND the number of rows (ScriptsNo) from the count(*): Here is my stored procedure:CREATE PROCEDURE csp_AuthorAccountInfo@CandidateID int,AS DECLARE @ScriptsNo int, @ManuscriptID int SELECT count(*) as ScriptsNo FROM Manuscripts WITH (NOLOCK) WHERE CandidateID = @CandidateID/* this is where it stops all the time :(Theoretically speaking, next SELECT will only return 1 row with Candidate's info*/SELECT c.*, l.LocationID, @ManuscriptID=m.ManuscriptID, l.State, cn.Country FROM Candidates c INNER JOINManuscripts m ONc.CandidateID = m.CandidateID INNER JOINLocations l ON c.LocationID = l.LocationID INNER JOINcn ON l.CountryCode = cn.CountryCodeWHERE c.CandidateID = @CandidateID/* next SELECT should normally return manu rows with Candidate's submitted manuscripts */SELECT m.ManuscriptID, m.IsReceived, msn.StageName, ms.DatePosted, ns.CommentsFROM Manuscripts m INNER JOINManuscriptStages ms ON m.ManuscriptID = ms.ManuscriptID INNER JOINManuscriptStageNames msn ON ms.StageNameID = msn.StageNameIDWHERE m.ManuscriptID = @ManuscriptIDORDER BY ms.DatePosted DESCGO
Hi, I currently have three queries running seperately which I'd like to join up..
However I'm sure it can be done..
Here goes:
I have one table which lists payments made (it stores a PaymentID from another table, a payment amount and an invoiceID)
Therefore there can be several records with the same PaymentID referenceing different invoices (i.e a user paying off several invoices with one payment)
I have one query which lists all of the invoices paid against one payment.
SELECT PaymentID, InvoiceID, PaymentAmount WHERE PaymentID = xxx AND PayType <> 'Credit'
I then have a second query which is ran against each individual invoice which shows the other payments which have been made against this invoice already
SELECT PaymentID, InvoiceID, PaymentAmount WHERE PaymentID <> xxx AND PayType <> 'Credit' AND InvoiceID = XXX
and final I have one query which lists the credits SELECT PaymentID, InvoiceID, PaymentAmount WHERE PayType = 'Credit' AND InvoiceID = XXX
All of the above lets me see an payment, which invoices have been paid against that payment.. and then for each invoice, any other payment which were made beforehand, and finally any credits against that invoice.
I run these from an ASP page in a loop which is pretty inefficient way of doing it.
I would much prefer to amalgamate the three queries above so I could see what I was paying now, what had already been paid and what was credited against each invoice from a PaymentID.. all in query.
If I were to create a stored procedure that searches a table using (optional) multiple parameters, what would be the best way to do the search. I want to try and avoid using several "IF" statements (like IF @FirstName IS NOT NULL, etc). How would I do it, or would I just be better off using several "IF" statements? Thanks... CREATE PROCEDURE intranet_search_GetEmployeesBySearch ( @FirstName NVarChar(100), @LastName NVarChar(100), @Phone NVarChar(50), @Cell NVarChar(100), @Pager NVarChar(100), @Ext NVarChar(50), @Email NVarChar(100), @Department NVarChar(200), @Position NVarChar(100), @IsManager Bit ) AS BEGIN
Our developers have gotten this idea lately that instead of having many small stored procedures that do one thing and have small parameter lists that SQL can optimize query plans for, its better to put like 8-10 different queries in the same stored procedure.
They tend to look like this:
create procedure UberProc (@QueryId varchar(50)) as
if @QueryId = 'First Horrible Idea' begin select stuff from something end if @queryid = 'Second really bad idea' begin select otherstuff from somethingelse end
I see the following problems with this practice:
1) SQL can't cache the query plan appropriately 2) They are harder to debug 3) They use these same sorts of things for not just gets, but also updates, with lots of optional NULLable parameters that are not properly handled to avoid parameter sniffing.
I have 4 sets of select queries under 1 stored proc, now on the report calling the stored proc via dataset. when i run the dataset the only first set of the select query related fields appearing under the dataset.
But on the back end sql server, if i execute the same stored proc, i get 4 resultsets in one single executioln.
i am not seeing the remaingin 3 resultsets, on the reports dataset.
Is it possible on the reports or not.
In the asp.net project i was able to use that kind of stored procedures whcih has multiple select statements in 1 procedure., i use to refer 0,1,2,3 tables under a dataset.
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.
I was wondering if anyone can explain the positives and negatives of using a single stored procedure that contains one or more distinct queries. I know there are problems with dynamic SQL but I am not proficient enough to know whether this falls under that umbrella.
For clarification, what I am referring to is this: In a single stored procedure, I have a parameter called Query_ID that is used to identify which query in the sproc that I want to execute. Then from my ASP page, I simply pass the appropriate value for Query_ID. So:
IF @QUERY_ID = 1 BEGIN SELECT [whatever] FROM [tbl1] WHERE [conditions] GROUP BY [something] ORDER BY [somethingelse] END ELSE IF @QUERY_ID = 2 BEGIN SELECT [whatever] FROM [tbl2] WHERE [conditions] GROUP BY [something] ORDER BY [somethingelse] END END
I am having one querry regarding the same line. In my stored procedure i am fetching the data from one table containing upto 5 to 6 million rows I made use of index in my database but then also I cant optimise my execution time of that sp. Please help me out of this problem.

The following code works fine using 3.5 Beta2 (System.Data.SQLServerCE.dll version 3.5.5365.0)
Using 3.5 RTM (System.Data.SQLServerCE.dll version 3.5.5386.0) it throws an error because it appears that the engine requires the input parameters to be either a) referenced by name or b) if not named, the Input parameters and INSERT columns statement must be in the same order as the actual table structure.
Error is "Cannot convert DateTime to UniqueIdentifier" - So I'm assuming its trying to stick the Parameters(1) value into [Col1], the UniqueIdentifier column.

Or swap the order of parameters added to the collection and use "INSERT INTO [Table1] ([ID], [Col1], [Col2]) VALUES (?, ?, ?)" , this works.
Did something change between Beta2 and RTM that now would dissallow the code listed in our Sample?
I've searched around and can't find any references to the problem I'm having. I'd appreciate any ideas or input.
I'm trying to use the OLEDB Destination for an insert at the end of a long data flow. I need to parameterize the input, and for some of the columns I need to use literal values instead of parameters. It seems like this should be the most common thing in the world, but I'm at a loss to get it to work.
I type in the SQL statement just like I would with an OLEDB Command transformation, with the ? character for the appropriate columns in the VALUES clause. However, when I try to use Parse Query I get this error:
"Parameter Information cannot be derived from SQL statements. Set parameter information before preparing command."
OK, so I start searching around for ways to set the parameter information. Nada. On the Mappings tab the parameter list is empty. I check MSDN and it says this:
"If you have entered a parameterized query by using ? as a parameter placeholder in the query text, use the Set Query Parameters dialog box to map query input parameters to package variables."
Set Query Parameters dialog box? I don't see this anywhere. What am I missing?
The options with the SQL Server Destination seem even more limited, as I don't see any way to use a SQL statement or stored procedure.
For the moment I'm going to stub this off with an OLEDB Command transformation with a downstream Trash desintation, but hopefully that's only going to be temporary.
I want to create a stored proc that might or might not recieve a value like below.
create proc cmine @vdate datetime = null as select * from table where mydate > @vdate
However if the value is null,( no value was supplied) I would not want to use the where clause. Should (or can you) use an if statement to check and see if no value was given to change the where clause? Thanks
Hi, I am having trouble inserting 2 fields in a row using a stored procedure. This works fine: Exec ('Insert Into NumbersPull (Number)'+ @SQL) but when I try to insert another value into field 2 it errors out: I try this: Exec ('Insert Into NumbersPull (Number,resultID) Select ('+ @SQL + '),' + @resultID' ) and get this error: ERROR: Line 2: Incorrect syntax near ')'. Thanks, Doug
