Issue With Dynamic SQL Stored Procedure And SSIS OLE DB Data Reader

May 16, 2006

We are writing SSIS packages to pull data from MSO€™s through a stored procedure and drop the output into the pipeline to store it on our local database.

Here is an example of a very simple data flow task that executes the following query in step 1

EXEC GetCustomerData @SELECT = 'OrganizationID', @FROM = 'Organization',@WHERE = 'StateOrProvinceCode = ''WA'''

This command is stored in a variable called SQLOrgCommand.
When I open the task and click on Columns I do not see any columns returned
This allows me to conclude that the metadata needed from the GetCustomerData is not understood by SSIS because the SP uses dynamic sql.


While profiling we realized that it executed the following SQL:

SET FMTONLY ON


to get the metadata. However when we ran the sp with FMTONLY ON we recieved the following errors

Msg 536, Level 16, State 5, Procedure sp_GetData, Line 100
Invalid length parameter passed to the SUBSTRING function.
Msg 536, Level 16, State 2, Procedure sp_GetData, Line 101
Invalid length parameter passed to the RIGHT function.
Msg 536, Level 16, State 5, Procedure sp_GetData, Line 116
Invalid length parameter passed to the SUBSTRING function.
Msg 536, Level 16, State 2, Procedure sp_GetData, Line 117
Invalid length parameter passed to the RIGHT function.
Msg 536, Level 16, State 5, Procedure sp_GetData, Line 187
Invalid length parameter passed to the SUBSTRING function.

The same stored procedure executed without FMTONLY OFF generates the proper output.

Is this a known bug in SQL Server? If so is there a patch that we can install.

Stored Procedure With Select, How To Use It With Data Reader?

Oct 6, 2006

I've created some store procedure for use with Insert. This works great. Now I'd like to be able to use Select statement so I can get the data in some textboxes.

Right now I use Select with SqlCommand and DataReader. This works fine, but I'd like to learn with Stored Procedure with this.

What do I put in the stored procedure to return found records and how what code should I use after executenonquery?

Dynamic Queries With Data Reader Source Adapter

Apr 16, 2008

I am a business user trying to build an incremental ETL package with SSIS. I have a working prototype on SQL Server 2005 where I select the max(ID) from the last successful run and pass that value into a variable. Then, in my Data Flow step, I select an OLE DB source adapter and use this variable in a custom select statement.

Here's my challenge....the live data is actually in a Postgres DB so I have to use a Data Reader Source adapter. When I try to pass my variable to this adapter the job bombs out. Does anyone know how to dynamically update the query text inside a Data Reader source adapter using variables or otherwise?

SSIS Data Reader Error Re-direct

Feb 18, 2008

Hi I'm currently trying to create a few DTS packages that Import some very wide tables, Im using an ODBC data source into a Data Reader. I want to re-direct any errors into an error destination. The problem I've got is that I can go in and set each column to redirect but was hoping I could select or specify that this needs to happen for all the rows? Does anyone know if this is possible and if so how I go about it?

Many thanks....

SSIS - Data Reader - Need To Use A Parameter - Connecting To UDB/DB2 On Sun Solaris

Aug 15, 2007

In several weeks of effort and research I cannot locate any method to get this to work and need some help. We've loaded the most recent version of the Microsoft OLE DB (Feb 2007) and have located several discussion threads on these and other forums that all point to the same conclusion... you cannot use this to talk to a UDB/DB2 instance on Sun Solaris unless you are pulling a full table. Any custom SQL will not work. So, I'm trying to setup a custom query which in most cases is to determine a date to use in the filter (where clause) and the rest of the query is static. The DataReader source does not support parameters and also appears to not support SQL command from variable. Any thoughts on how to get this to work without having to read the full table and pass the data to subsequent filters within the package???

Thanks

Special Character Problems With SSIS Data Reader Using ODBC Driver For DB2

Sep 5, 2007



Hi,
in SSIS I read data from a DB2 database on AS400 using the Client Access ODBC Driver for DB2 from IBM and write it to a SQL Server database. Since it does not work using the odbc driver as data source directly, I use a data reader component with .net providersodbc.
Some special characters were not translated correctly when read from DB2. They show up as ? in the SQL Server target table.


I tried to change the client locale in the ODBC connection properties but it did not help me. I tried changing all other settings in odbc but it still does not work.


In dts I could source all the data without this problems and good speed using the same nodbc driver.


The OLEDB Providers delivered with SSIS do not work in SSIS or I am too stupid to configure them correctly. They are even too slow as I explained above.


I cannot use the MS OLEDB Provider for DB2, because it works only in Enterprize Edition and we only have the Standard Edition.


Thus, only using Client Access ODBC Driver for DB2 with net providersodbc (as bridge) is performant enough and works on Itanium. But how to work around the problem with the special characters?


Best regards,
Stefoon

SQL 2012 :: SSIS Passing Parameters To Stored Procedure That Changes Based On The Data Being Passed?

Jun 23, 2015

Using the following:

SQL Server: SQL Server 2012
Visual Studio 2012

I have created an SSIS package where I have added an Execute SQL Task to run an existing stored procedure in my SQL database.

General Tab:

Result Set: None
Connection Type: OLE DB
SourceType: Direct Input
IsQueryStoredProcedure: False (this is greyed out and cannot be changed)
Bypass Prepare: True
SQL Statement: EXEC FL_CUSTOM_sp_ml_location_load ?, ?;

Parameter Mapping:

Variable Name Direction Data Type Prmtr Name Prmtr Size
User: system_cd Input NVARCHAR 0 10
User: location_type_cd Input NVARCHAR 1 10

Variables:

location_type_cd - Data type - string; Value - Store (this is static)
system_cd - Data type - string - ??????
The system code changes based on the system field for each record in the load table

Sample Data:

SysStr # Str_Nm
3 7421Store1
3 7454Store2
1815061Store3
1815063Store4
1615064Store5
1615065Store6
1615066Store7
7725155Store8

STORED PROCEDURE: The stored procedure takes data from a load table and inserts it into another table:

Stored procedure variables:
ALTER PROCEDURE [dbo].[sp_ml_location_load]
(@system_cd nvarchar(10), @location_type_cd nvarchar(10))
AS
BEGIN .....................

This is an example of what I want to accomplish: I need to be able to group all system 3 records, then pass 3 as the parameter for system_cd, run the stored procedure for those records, then group all system 18 records, then pass 18 as the parameter for system_cd, run the stored procedure for those records and keep doing this for each different system in the table until all records are processed.

I am not sure how or if it can be done to pass the system parameter to the stored procedure based on the system # in the sys field of the data.

Multiple Stored Procedure...or 1 Dynamic Procedure?

Jul 3, 2007

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??

Cheers,
Justin

SSIS Hard Time Getting Back XML Return Data From Stored Procedure Call Executed By Execute SQL Task

Aug 9, 2006

I'm having a hard time to getting back an xml data back from a stored procedure executed by an Execute SQL task.

I'm passing in an XML data as a parameter and getting back resulting XML data as a parameter. The Execute SQL task is using ADO connection to do this job. The two parameters(in/out) are type of "string" and mapped as string.

When I execute the task, I get the following error message.

[Execute SQL Task] Error: Executing the query "dbo.PromissorPLEDataUpload" failed with the following error: "The incoming tabular data stream (TDS) remote procedure call (RPC) protocol stream is incorrect. Parameter 2 ("@LogXML"): Data type 0xE7 has an invalid data length or metadata length.". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.

I also tried mapping the parameter as XML type, but that didn't work either.

If anyone knows what's going on or how to fix this problem please let me know. All I want to do is save returning XML data in the parameter to a local package variable.

Thanks

Dynamic Where In Stored Procedure Help

Sep 7, 2004

Hi all,

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?

Thanks,

James

Stored Procedure With Dynamic Sql

Aug 6, 2004

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.

So anyone can help me on this issue.

Thanks.

Dynamic WHERE In Stored Procedure

Sep 29, 2007

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'm calling it like this:


Dim cmdX, cmdParam, rsX
cmdParam = "OnSpecial"

set cmdX = Server.CreateObject("ADODB.Command")
cmdX.ActiveConnection = conn_STRING
cmdX.CommandText = "dbo.getProducts"
cmdX.Parameters.Append cmdX.CreateParameter("@RETURN_VALUE", 3, 4)
cmdX.Parameters.Append cmdX.CreateParameter("@param1", 200, 1,50,cmdParam)
cmdX.CommandType = 4
cmdX.CommandTimeout = 0
cmdX.Prepared = true
set rsX = cmdX.Execute
rsX_numRows = 0


I know for a fact that I have products in my dbase with the bit column 'OnSpecial' set to 1, yet no records are coming back.

Any pointers would be most appreciated.

Dynamic SQL Stored Procedure

Dec 4, 2007



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!

Old Proc without issues----

Does a lookup of MLS Property data for reverse link. This is susceptible to error in that if erroneous data is given

Permissions With Dynamic SQL Within Stored Procedure

Aug 1, 2006

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.

Variables In Dynamic SQL In A Stored Procedure

Aug 23, 2007

I am taking my first steps into stored procedures and I am working on a solution for efficiently paging large resultsets with SQL Server 2000 based on the example on 4Guys: http://www.4guysfromrolla.com/webtech/042606-1.shtml
The problem with my stored procedure is, is that it doesn't seem to recognize a variable (@First_Id) in my dynamic Sql. With this particular sproc I get the error message: "Must declare the scalar variable '@First_Id'"It seems to be a problem with 'scope', though I still can't yet figure out. Can anyone give me some hints on how to correctly implement the @First_Id in my stored procedure? Thanks in advance!
Here's the sproc:
ALTER PROCEDURE dbo.spSearchNieuws(@SearchQuery NVARCHAR(100) = NULL,@CategorieId INT = NULL,@StartRowIndex INT,        @MaximumRows INT,@Debug BIT = 0)ASSET NOCOUNT ONDECLARE @Sql_sri   NVARCHAR(4000),@Sql_mr    NVARCHAR(4000),@Paramlist NVARCHAR(4000),@First_Id  INT, @StartRow  INTSET ROWCOUNT @StartRowIndexSELECT @Sql_sri = 'SELECT @First_Id = dbo.tblNieuws.NieuwsId FROM dbo.tblNieuwsWHERE 1 = 1'IF @SearchQuery IS NOT NULLSELECT @Sql_sri = @Sql_sri + ' AND FREETEXT(dbo.tblNieuws.Nieuwskop, @xSearchQuery)'              IF @CategorieId IS NOT NULLSELECT @Sql_sri = @Sql_sri + ' AND dbo.tblNieuws.CategorieId = @xCategorieId'SELECT @Sql_sri = @Sql_sri + ' ORDER BY dbo.tblNieuws.NieuwsId DESC'SET ROWCOUNT @MaximumRows SELECT @Sql_mr = 'SELECT dbo.tblNieuws.NieuwsId, dbo.tblNieuws.NieuwsKop, dbo.tblNieuws.NieuwsLink, dbo.tblNieuws.NieuwsOmschrijving, dbo.tblNieuws.NieuwsDatum,                 dbo.tblNieuws.NieuwsTijd, dbo.tblNieuws.BronId, dbo.tblNieuws.CategorieId, dbo.tblBronnen.BronNaam, dbo.tblBronnen.BronLink, dbo.tblBronnen.BiBu, dbo.tblBronnen.Video,                dbo.tblCategorieen.CategorieFROM       dbo.tblNieuws INNER JOIN                dbo.tblBronnen ON dbo.tblNieuws.BronId = dbo.tblBronnen.BronId INNER JOIN                dbo.tblCategorieen ON dbo.tblNieuws.CategorieId = dbo.tblCategorieen.CategorieId AND                 dbo.tblBronnen.CategorieId = dbo.tblCategorieen.CategorieId         WHERE dbo.tblNieuws.NieuwsId <= @First_Id          AND 1 = 1'               IF @SearchQuery IS NOT NULLSELECT @Sql_mr = @Sql_mr + ' AND FREETEXT(dbo.tblNieuws.Nieuwskop, @xSearchQuery)'           IF @CategorieId IS NOT NULLSELECT @Sql_mr = @Sql_mr + ' AND dbo.tblNieuws.CategorieId = @xCategorieId'     SELECT @Sql_mr = @Sql_mr + ' ORDER BY dbo.tblNieuws.NieuwsId DESC'IF @Debug = 1PRINT @Sql_mr  SELECT @Paramlist = '@xSearchQuery NVARCHAR(100),     @xCategorieId INT'EXEC sp_executesql   @Sql_sri, @Paramlist,     @SearchQuery, @CategorieIdEXEC sp_executesql   @Sql_mr, @Paramlist,     @SearchQuery, @CategorieId

Trying To Build Dynamic Stored Procedure

Jun 6, 2008

My existing ASP 1.0 site keeps getting hacked using SQL injections.  I have rewritten the site in ASP 3.5 to stop the attacks but cannot figure out how to dynamically generate a basic keyword search.
I am trying to take the keywords entered into an array and then construct the WHERE clause - not having much luck.  Getting either errors or double LIKE statements. Need some help.
string[] SqlKWSrch; 
SqlSrch = KWordSrch.Text;SqlKWSrch = SqlSrch.Split(' ', ',');     int AStop = SqlKWSrch.Length;     int i = 0;        foreach( string a in SqlKWSearch )       {           if (i <= AStop)           {               SqlWHR = SqlWHR + "L_Kwords LIKE '%' + " + " '" + SqlKWSrch[i] + "' " + " + '%' AND ";           }           else           {               SqlWHR = SqlWHR + "L_Kwords LIKE '%' + " + " '" + SqlKWSrch[i] + "' " + " + '%' ";           }            i++;       }
1) I can't seem to properly terminate the final LIKE statement2) can't figure out how to pass 'SqlWHR' to the procedure
GIVEN KEYWORDS: 'antique chairs' entered I want to end up with the below SP, the @SqlWHR parameter appeared to have worked once but it probably was an illusion.
PROCEDURE KeyWordSearch@SqlWHR varchar(100)AS
SELECT L_Name, L_City, L_State, L_Display FROM tblCompanies WHERE L_Kwords LIKE '%' + 'antique' + '%' AND L_Kwords LIKE '%' + 'chairs' + '%' AND L_Display = 1
RETURN
 
Thank you

Dynamic Query In Stored Procedure

Jun 13, 2008

Hi, I have a table with values such as test1, test2, test3, test4, test5.
I need to write a stored procedure with paramater (number TINYINT, number2 TINYINT), the number represents the field that I'm going to select and compare. For example if I pass in (1,5) I will need the fields test1 and test5 and store them in Temp and Temp2. 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

Dynamic WHERE Clause To Stored Procedure

May 25, 2004

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:

---------------------------------------------------
@crit varchar(100)

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.

cheers!

Dynamic ORDER BY Within Stored Procedure

Jul 7, 2004

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.

Dynamic Where Clause In Stored Procedure

Jul 23, 2004

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. Now I wonder if I should use dynamic Where clause or should I use some kind of switch, maybe case and hardcode my where clause. I first created several stored procedures like Documents_GetByRole, Documents_GetByRoleByStatus ... and now I want to combine them into one SP. Which approach is better. Thanks for your help.

Problem In A Dynamic Stored Procedure---help

Sep 7, 2004

I create a stored procedure as following:
........

CREATE Procedure myAutoSearch
(
@Make varchar(50),
@Model varchar(50),
@AutoType varchar(50),
@Miles float,
@Zipcode varchar(5)
)
AS

DECLARE @RowCount int
SELECT @RowCount = Count(*) FROM ZIPCodes WHERE ZIPCode = @Zipcode AND CityType = 'D'

if @RowCount > 0
BEGIN

SELECT
z.ZIPCode, z.City, z.StateCode, a.Make, a.Model, a.AutoPrice, a.AutoPrice2, a.AutoYear,
a.Mileage, a.AdID, a.ImageURL, dbo.DistanceAssistant(z.Latitude,z.Longitude,r.Latitude,r.Longitude) As Distance
/*
The above functions requires the Distance Assistant.
*/
FROM
ZIPCodes z, RadiusAssistant(@ZIPCode,@Miles) r, AutoAd a
WHERE
z.Latitude <= r.MaxLat
AND z.Latitude >= r.MinLat
AND z.Longitude <= r.MaxLong
AND z.Longitude >= r.MinLong
AND z.CityType = 'D'
AND z.ZIPCodeType <> 'M'
AND z.ZIPCode = a.Zipcode
AND a.AdActive = '1'
AND a.AdExpiredate >= getdate()
AND a.Make = @Make
AND dbo.DistanceAssistant(z.Latitude,z.Longitude,r.Latitude,r.Longitude) <= @Miles
/*
The above functions requires the Distance Assistant.
Also note that SQL Server caches the results so that this and the "SELECT dbo.DistanceAssistant"
functions are both only computed once.
*/
ORDER BY Distance, Make

END
ELSE
SELECT -1 As ZIPCode
--ZIP Code not found...

....................

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.

Building A Dynamic Stored Procedure

Mar 30, 2005

Hi

I am in the very final stages of
building a dating app for a client, I am totally stuck with the
advanced search page. been googling for days with limited success

For the most basic of purposes I have added a few form fields to my search.aspx page;
county (Dropdown list)
min age (Dropdown list)
max age (dropdown list)
Smoker (check box)
keyword (textbox)

My codebehind passes the vars to a stored procedure
@county = me.county.selectedvalue
etc
My problem is the stored procedure I sort of have the following but I can't get it to run
<code>
ALTER PROCEDURE dbo.TEST_ADVANCED_SEARCH
(@countyID int ,
@MaxAge
varchar(100),
@MinAge
varchar(100),

@smoker tinyint),
@keyword
varchar(250))

AS

DECLARE @SQL Varchar
(4000)

SELECT  @SQL =   'dbo.user_accounts.profileComplete,
dbo.user_accounts.countyID, dbo.user_profiles.smoker,
dbo.user_profiles.Age
FROM         dbo.user_accounts INNER
JOIN
                     
dbo.user_profiles ON dbo.user_accounts.userID =
dbo.user_profiles.userID
WHERE     (dbo.user_accounts.profileComplete =
1)'

IF @countyID > 0
SELECT @SQL = @SQL + ' AND
(dbo.user_accounts.countyID = @countyID)'

IF @MaxAge IS NOT
NULL
SELECT @SQL = @SQL + ' AND (dbo.user_profiles.Age <= @MaxAge)
'

IF @MinAge IS NOT
NULL
SELECT @SQL = @SQL + ' AND (dbo.user_profiles.Age >= @MinAge)
'


IF @smoker > 0
SELECT @SQL = @SQL + ' AND
(dbo.user_profiles.smoker = 1)'

IF @keyword IS NOT
NULL
SELECT @SQL = @SQL + ' AND (dbo.user_profiles.Description LIKE @MinAge)
'


EXEC(@SQL)
</code>
If I can get this to work I can add the remaining fields that I need

Am I Missing something glaringly obvious?
Any help or advice gratefully received

Thanks

Help With Dynamic Where Clause In Stored Procedure

I have a stored procedure being called based on user search criteria. Some, the colour and vendor fields are optional in the search so i do not want that portion of the procedure to run.

at this point i keep getting errors in the section bolded below
it never seems to recognize anything after the if @myColours <> 'SelectAll'

CREATE Procedure PG_getAdvWheelSearchResults3

Anyone know how i should word the if...statements?

The problem is that I want to call different procedures that can give back different columns.
Therefor I would have to define the table #T1 generically.But I don't know how.
Can anyone help me on this problem?
