Can anyone help me with this dumb question?
I want to use a stored procedure to bring back a recordset depending if a bit column is set to 1. My table has a number of columns that are of Data Type bit and I want to be able to specify which particular column I'm interested in as a parameter when I call the Stored Procedure.
I have set up the Stored Procedure as follows:
CREATE PROCEDURE getProducts
@param1 varchar(50)
AS
SELECT ProductID, ProductName
FROM dbo.Products
WHERE @param1 = '1'
GO
I have a stored procedure and in that I will be calling a stored procedure. Now, based on the parameter value I will get stored procedure name to be executed. how to execute dynamic sp in a stored rocedure
at present it is like EXECUTE usp_print_list_full @ID, @TNumber, @ErrMsg OUTPUT
I want to do like EXECUTE @SpName @ID, @TNumber, @ErrMsg OUTPUT
Ok, so i have this program, and at the moment, it generates an sql statement based on an array of db fields, and an array of values...
my question is this, is there any way to create a stored procedure that has multiple dynamic colums, where the amount of colums could change based on how many are in the array, and therefore passed by parameters...
if this is possible, is it then better the pass both columns and values as parameters, (some have over 50 columns)...or just create a seperate stored procedure for each scenario?? i have no worked out how many this could be, but there is 6 different arrays of colums, 3 possible methods (update, insert and select), and 2 options for each of those 24...so possibly upto 48 stored procs...
this post has just realised how deep in im getting. i might just leave it as it is, and have it done in my application...
but my original question stands, is there any way to add a dynamic colums to a stored proc, but there could be a different number of colums to update or insert into, depending on an array??
I have a web application that has a search engine that returns records based off what the user selects in the search engine. I am currently using coalesce in the where statement in my stored procedure to return the records. For eample, where field1= coalesce(@parm1,field1). I don't know if this example is better than building the sql statement dynamically in a parameter then executing the parameter with sp_executesql. Can someone explain to me which is better or if there is a better solution?
CREATE PROCEDURE ggg_test_sp @start_date datetime,@end_Date datetime AS
SET NOCOUNT ON DECLARE @sqlstmt varchar(1000)
SELECT @sqlstmt='SELECT * FROM ggg_emp WHERE date_join BETWEEN ' +CONVERT(varchar(10),@start_date-1,101) + ' AND ' +CONVERT(varchar(10),@end_Date+1,101)
SELECT @sqlstmt EXEC (@sqlstmt)
GO
I want to apply date filter in the above sp with dynamic sql stmt. When i execute the above procedure with date ranges( @start_date=07/06/2004 AND @end_Date= 08/06/2004)i am not getting any result because my @sqlstmt variable has the select stamet
SELECT * FROM ggg_emp WHERE date_join BETWEEN 07/06/2004 AND 08/06/2004
BUT it should have the sqlstmt as
SELECT * FROM ggg_emp WHERE date_join BETWEEN '07/06/2004' AND '08/06/2004' to produce the required result
I know that for the above SP we dont need any dynamic sql but this is just an example.
I have a stored procedure spGetAccessLogDynamic and when I try to callit I get the following error:Server: Msg 2812, Level 16, State 62, Line 1Could not find stored procedure 'S'.I dont know why because I dont have anything refering to storedprocedure 'S'I have ran my SQL String with sample values and it works fine.

We are continuing to have issues with a certain stored procedure using dynamic sql. The issue arose when we tried to clean the stored procedure up, and seemed to have zero problems in staging. As soon as we moved it into production, the stored proc caused excessive blocking and completely slowed down our production environment. We immediately rolled back the older version and production is back to normal.
After looking at the new procedure I don't understand how it could cause blocking. Any help is much appreciated!

Okay, I have sort of a peculiar permissions question I am wondering if someone can help me with. Basically, here's the scenario... I have a CLR stored procedure which does some dynamic SQL building based on values sent in via XML. It's a CLR stored procedure using XML because I want to build a parameterized statement (to guard against SQL Injection) based on a flexible number of parameters which are basically passed in the XML. The dynamic SQL ends up reading from a table I'll call TableX and I actually discovered an (understandable) quirk with security. Basically, the connection context is using security for a low-privilaged Windows account ("UserX") and UserX has no permission to the table referenced in the dynamic SQL but because of the dyanmic nature of the query, the stored procedure ends up adopting the security context of UserX. Naturally, this throws a security exception saying UserX has no SELECT permission on TableX. Now, I can give UserX read permission to the table in question to get things running, but one of the points of using stored procedures is to defer security to the procedure level vs. configuration for tables or columns. So in striving toward my ideal of security at the procedure level, my question is what is the best way to allow minimum privilege in this case? I thought about having the internals of the CLR stored procedure run under a different (low-privalaged) security context, but I am wondering if there's an alternate configuration that may be as secure, but simpler. PS - Please don't let this degenerate into a conversation about OR mappers. I know that happens a lot on these forums.
Hi, I need to create a stored procedure, which needs to accept the column name and table name as input parameter, and form the select query at the run time with the given column name and table name.. my procedure is, CREATE PROC spTest @myColumn varchar(100) , @myTable varchar(100) AS SELECT @myColumn FROM @myTable GO This one showing me the error, stating that myTable is not declared.. .............as i need to perform this type of query for more than 10 tables.. i need the stored procedure to accept the column and table as parameters..

How do I write the following to so it will dynamically select which field to use when passing the parameters? DECLARE @Temp TINYINT, DECLARE @Temp2 TINYINT, SELECT top 1 Temp = test1, Temp2 = test5 from table
Hi all! I need to create a stored procedure with a parameter and then send a WHERE clause to that parameter (fields in the clause may vary from time to time thats why I want to make it as dynamic as possible) and use it in the query like (or something like) this:
SELECT fldID, fldName FROM tblUsers WHERE @crit ----------------------------------------------------
Of course this does not work, but I don't know how it should be done, could someone please point me in the right direction on how to do this kind of queries.
I am trying to do something similar to the following where I want to perform dynamic ordering on two tables that have been unioned as shown below.
CREATE PROCEDURE procedure_name @regNum varchar(14), @sortOrder tinyint = 1 AS SELECT Filler_OrdNum As 'Accession', RTrim(Obs_Code) As 'Observation', REG As 'Register', Obs_Date As 'Observation Date' FROM tblSPG_Header WHERE REG = @regNum UNION SELECT Filler_OrdNum As 'Accession', RTrim(Obs_Code) As 'Observation', REG As 'Register', Obs_Date As 'Observation Date' FROM tblRCH_Header WHERE REG = @regNum ORDER BY Obs_Date DESC GO
Note that I am only sorting on the Obs_Date column, but I'd like to be able to sort on any column within the selection list. I know that I need to use:
ORDER BY CASE WHEN @sortOrder = 1 THEN Obs_Date END DESC
but I frequently get the following error when I try to do so:
"ORDER BY items must appear in the select list if the statements contain a UNION operator"
If anyone can offer any suggestions, I would appreciate it. Thanks.
Hi, I have several parameters that I need to pass to stored procedure but sometimes some of them might be null. For example I might pass @Path, @Status, @Role etc. depending on the user.

This stored procedure work very well.
The question is how I add some dynamic condition inside the where condition.
I want to add:
If @Model <> "See All Models" AND a.Model = @Model'
If @AutoType <> "New/Used" AND a.Condition = @AutoType
I try several ways, but fail.
If you know how to add these two dynamic parameters into the condition of stored procedure, please help.

The SELECT item identified by the ORDER BY number 1 contains a variable as part of the expression identifying a column position. Variables are only allowed when ordering by an expression referencing a column name. Is this possible to do?
I have a small problem writing a stored procedure in a SQL Server 2000 database.
I would like to generate som part of the SQL inside this stored procedure that is used in an IN expression of my WHERE clause. There is no problem for me to generate a string containing my expression, the problem is that SQL-Server donīt generate a resulting SQL-statement.
Example:
CREATE PROCEDURE spDynStatement AS
DECLARE @sPartOfSQLStatement NVARCHAR(100)
-- Some T-SQL that generates the dynamic part of the SQL-statement -- . -- . -- .
-- As substitute I insert the string expression SET @sPartOfSQLStatement = '''1''' + ', ' + '''1.5'''
I have this stored procedure: SELECT * from purchase ORDER BY CASE @OrderBy WHEN 'traveller_name' THEN cast(traveller_name as nvarchar(100)) WHEN 'canceled' THEN cast(canceled as bit) END
the @OrderBy is a nvarchar(100) parameter traveller_name is an nvarchar(100) field canceled is a bit field
When I execute the stored procedure it works fine until I execute it sorting by canceled field. After that, I cannot sort it again using the traveller_name field. I get this eror: Conversion failed when converting the nvarchar value 'Jason' to data type bit. (Jason is a record in the traveller_name) Removing the castings and sorting by just the column name does not help.
We have a procedure that does some complicated table joins to populate a temporary table (declared in the proc) and then extraneous rows are removed from the table and the remaining rows are returned.
On the production server the procedure takes 22 seconds, but the identical query in a dynamic session window of SQL Server Management Studio takes 2 seconds. That doesn't make any sense.
We've profiled the procedure and discovered that the small loop at the end of the query runs through twice with each iteration taking 10 seconds. Again - the same section (but dynamic) profiles in at 0 seconds. We further narrowed it down to the compound delete statement from the @tblResults table.
Here's the looped section of code:
-- now delete the entries with no content
declare @deleted int
set @deleted = 1
declare @tmp table ([Id] int)
while @deleted <> 0
begin
delete from @tmp
-- get all entries with no child nodes
insert into @tmp ([Id])
select distinct r.[id] from @tblResults r
where r.[id] not in
(
select [Id] from @tblResults
where [Id] in (select distinct ParentId from @tblResults)
)
-- delete entries with no documents and region match -- (this is where the slowdown occurs)
delete from @tblResults
where [id] in
(
select t.[id] from @tmp t where t.[id] not in
(select distinct dm.metatagid from documentmetatag dm
where dm.documentid in
(select distinct dr.documentid from documentregion dr, @region r
where (dr.regionid = r.regionId or @regionIds is null)
)
)
)
select @deleted = @@rowcount
end
We then return all rows from the @tblResults table.
We are totally stumped on why the procedure would take so much longer than running the same query in a SQL Manager window. Is there some issue with temporary tables as variables in a procedure? Any ideas anyone?
I have the following sp:@TABLE_NAME varchar(255), @CONTROL_ID int
AS DECLARE @sql varchar(4000) SELECT @sql = 'DELETE FROM [' + @TABLE_NAME + '] WHERE CONTROL_ID = 5'SELECT @sql = 'DELETE FROM [' + @TABLE_NAME + '] WHERE CONTROL_ID = ' + @CONTROL_ID + '' EXEC (@sql) When I use the the first SELECT line, it works great.When I use the second dynamic select, SQL raises an error: Syntax error converting the varchar value 'DELETE FROM [TABLE_SETTINGS] WHERE CONTROL_ID = ' to a column of data type int.What is wrong?
Hi, I hope some one can help me. I have a stored procedure (Microsoft SQL 2005 Express Edition) that I want users to be able to dynamically set the, group by, order by (@orderby) and where clause (@where). I have managed to get the group by to work but can't seem to get the where and order by to work. Here's my stored procedure. Any idea how this can be done? ALTER PROCEDURE [dbo].[sp_aggregate] -- Add the parameters for the stored procedure here @finfileid int, @phaseid int, @supplierid int, @measurementid int, @roleid int, @groupby int, @orderby int, @where int AS BEGIN -- SET NOCOUNT ON added to prevent extra result sets from -- interfering with SELECT statements. SET NOCOUNT ON; -- Insert statements for procedure here SELECT MAX(ProjectFinFileMonthItems.ProjFinFileMonthItemsMonthId) AS ProjFinFileMonthItemsMonthId, SUM(ProjectFinFileMonthItems.ProjFinFileMonthItemsValue * ProjectFinFileMonthItems.ProjFinFileMonthItemsRate * ProjectFinFileMonthItems.ProjFinFileMonthItemsAvail / 100) AS total, MAX(ProjectFinFileItems.ProjPhaseId) AS phaseid, MAX(ProjectFinFileMonthItems.ProjDeliveId) AS deliveid, MAX(ProjectFinFileMonthItems.SupplierId) AS supplierid, MAX(ProjectFinFileMonthItems.ProjFinFileItemsId) AS ProjFinFileItemsId, MAX(ProjectFinFileMonthItems.ProjFinFileMonthItemsId) AS ProjFinFileMonthItemsId, MAX(ProjectFinFileMonthItems.ProjDeliveId) AS ProjDeliveId, MAX(ProjectPhases.ProjectPhaseName) AS ProjectPhaseName, MAX(Suppliers.SupplierName) AS SupplierName, MAX(ProjectFinFileMonthItems.RoleId) AS RoleId, MAX(Measurements.MeasurementName) AS MeasurementName, MAX(ProjectFinFileMonthItems.MeasurementId) AS MeasurementId, MAX(ProjectFinFileMonthItems.FinDataTypeId) AS FinDataTypeId, MAX(FinDataTypes.FinDataTypeName) AS FinDataTypeName, max(ProjectFinFileItems.FinFileId) as finfileid FROM ProjectFinFileItems INNER JOIN ProjectFinFileMonthItems ON ProjectFinFileItems.ProjFinFileItemsId = ProjectFinFileMonthItems.ProjFinFileItemsId LEFT OUTER JOIN FinDataTypes ON ProjectFinFileMonthItems.FinDataTypeId = FinDataTypes.FinDataTypeId LEFT OUTER JOIN Measurements ON ProjectFinFileMonthItems.MeasurementId = Measurements.MeasurementId LEFT OUTER JOIN Roles ON ProjectFinFileMonthItems.RoleId = Roles.RoleId LEFT OUTER JOIN ProjectPhases ON ProjectFinFileItems.ProjPhaseId = ProjectPhases.ProjectPhaseId LEFT OUTER JOIN Suppliers ON ProjectFinFileMonthItems.SupplierId = Suppliers.SupplierId /*dynamic where clause needs to go here */ /*dynamic group by clause */ GROUP BY CASE when @groupby=1 then ProjectFinFileItems.projphaseid --phaseid when @groupby=2 then ProjectFinFileMonthItems.supplierid -- supplierid when @groupby=3 then ProjectFinFileMonthItems.measurementid -- measurment when @groupby=4 then ProjectFinFileMonthItems.roleid --role else ProjectFinFileMonthItems.ProjFinFileMonthItemsId END /*dynamic order clause needs to go here */ END cheers Mark :)
Hi i have a page whereby the user can make a search based on three things, they are a textbox(userName), dropdownlist(subcategoryID), and region (regionID). The user does not have to select all three, he or she can enter a name into the textbox alone and make the search or enter a name into the textbox and select a dropdownlist value, my question is how can i build this procedure, this is what another user suggested but i am having trouble; ALTER PROCEDURE [dbo].[stream_UserFind] ( @userName varchar(100), @subCategoryID INT, @regionID INT )AS declare @StaticStr nvarchar(5000)set @StaticStr = 'SELECT DISTINCT SubCategories.subCategoryID, SubCategories.subCategoryName,Users.userName ,UserSubCategories.userIDFROM Users INNER JOIN UserSubCategories ON Users.userID= UserSubCategories.userIDINNER JOINSubCategories ON UserSubCategories.subCategoryID = SubCategories.subCategoryID WHERE UserName like @UserName' if(@subCategoryID <> 0) set @StaticStr = @StaticStr + ' and SubCategories.subCategoryID = @subCategoryID 'if(@regionID <> 0) set @StaticStr = @StaticStr + ' and SubCategories.RegionId = @regionID ' exec sp_executesql @StaticStr )
I have a situation where I'll need to get results from tables based on totally arbitrary filters. The user can select the field to compare against, the value, the comparison operator, and the boolean operator, so each bit in brackets would be configurable:[field] [>] [value] [and]The user can specify an arbitrary number of these, including zero of them. I like the coalesce function for situations that are a little more structured, but I think I'm stuck generating a dynamic query for this -- please correct e if I'm wrong!
I have only one table (Products) with 3 columns, PKID(int), CompanyID(int) and Product Name(nvarchar). The products table fills a CheckBoxList Control; the values of the ListItem's are the PKID of the Products Table. When a user ticks the check boxes to search for products, I generate a comma deliminated string of ONLY CHECKED products. For example I now have a string "3,5,4,6" which represent the Product PKID's. We can assume the values are not in order. My question is: Without knowing how many values are parsed to the stored procedure. How can I query the Products table for the CompanyID's? I've been banging my head for days thinking how to structure such a DB, Stored Procedures and HTML Controls. Am I going about this the wrong way, some advice would be really appriciated. Kind Regards.
