Hi. I can't seem to get my dynamic where clause right.
The pseudo code is such:
when gender is not null and is not 'show all' then create the condition "when tab1.gender = @gender".
and, when country is not null and is not 'show all' then create the condition "when tab1.country = @country".
and, finally, create the condition where tab1.bday_year is
between @toage AND @fromage (this will never be empty or null).
I have tried many variations, the most recent being below.
But, the resulting data does not act as it should (or it won't compile) :
Code:
WHERECASEWHEN @gender <> 'show all' THEN tab1.gender = @gender
WHEN @country <> 'show all' THEN tab1.country = @country
tab1.bday_year BETWEEN @toage AND @fromage END
I am looking to do a dynamic IN clause, such as the following.create procedured usp_SPTest
@variable varchar(150) AS
select * from table where ID IN (@variable) GO
Then execuuting this withusp_SPTest '''1'',''2''' Basically this won't work and gives an error Syntax error converting the varchar value ''1','2'' to a column of data type int. which makes sense. Is there anyway to do this outside of a dynamic SQL statement? According to http://www.sommarskog.se/dynamic_sql.html#List it doesn't look promising but unpacking the list into a table is a bit over board for this in my opinion. Any help is appreciated.
HiI need some advice on which direction to take!Consider this statement:SELECT business_name FROM myTable WHERE town = @town AND county = @countyMy problem is that i will not always have the @county variable available. Is there a way to use an IF or a CASE inside the SQL statement (i know i can create two seperate sql statments but dont want to do it this way)? If it makes it easier, when the @county variable is not available, it has a value of 0.thanks againPs, i also know how to do it using dynamic sql using the EXEC() command, but i'd prefer to steer clear of this method also.
I pass a WHERE clause to a sp and use EXEC to execute it. it works fine if it does not include datetime Type in WHERE clause. however, if it did, the an error will be shown up "Unclosed quotation mark after the character string '2'.". I try to copy that clause and run as query in SQL server. there is no problem.
the Where clause is (Status='Open' or Status='On Going' or Status='Hold' or Status='Close') And (Found_Date BETWEEN ' '2007-11-01'' And ''2007-11-30'')
I am trying to write a stored procedure usp_select using dynamic sql to select from a table. The stored procedure will accept the where clause and/or the where clause parameters. I have tried 3 different methods -
Method 1 - exec usp_select @whereCondition='col1 like ''abc%'' and col2 = ''xyz''' In usp_select, I'll build and execute the sql like - set @sql = N'select * from table ' + @whereConition exec sp_executesql @sql (basically @sql becomes - select * from table where col1 like 'abc%' and col2 = 'xyz')
Method 2 - exec usp_select @whereCondition='col1 like @p1 and col2 = @p2', @WhereParams='@p1=abc%,@p2=xyz'
In usp_select, I'll parse out the values in @WhereParams and then build and execute the sql like -
(basically @sql becomes - declare @p1 nvarchar(10), @p2 nvarchar(10); set @pt = 'abc%', @p2 = 'xyz'; select col1 from table1 where col1 like @p1 and col2 = @p2)
Method 3 -
similar to Method 2 but exec(@sql) will be structured to become - exec(declare @vparam nvarchar(100), @p1 nvarchar(10), @p2 nvarchar(10);
set @vparam='@p1 nvarchar(10), @p2 nvarchar(10)'
set @p1 = 'abc%', @p2 = 'xyz';
execute sp_executesql N''select col1 from table1 where col1 like @p1 and col2 = @p2', @vparam, @p, @p2)
When I run sql profiler on the 3 methods, method 1 and 2 always result in a Cache Miss on the entire sql structure. On method 3, a Cache Miss always occurs on the first part of the sql, ie, the first 3 lines where I declare and set the variables. Then a Cache Hit will happen on the execute sp_executesql part.
Do I have any performance gain using method 3 with both a Cache Miss and a Cache Hit?
I hope this is not too confusing. Because I do not know the where condition to the select procedure and hardcoding the values as in method 1 always results in a Cache Miss, therefore, I come up with the ideas in Method 2 and 3.
I have a table (tblRestore) that has the following data FilePath Included FileType C:DataProjectsBeacon 1 Directory C:DataProjectsBeaconPDA 1 Directory C:DataProjectsBeaconBeaconVisual Studio 2005 0 Directory C:DataProjectsBeaconVisual Studio 2005 0 Directory C:DataProjectsBeaconPDAAuditPDAWM5 0 Directory
I want to use the data in this table to dynamically create a where clause that would look like this
WHERE (ParentDirectory + '' LIKE 'C:DataProjectsBeacon\%' OR ParentDirectory + '' LIKE 'C:DataProjectsBeaconPDA\%')
AND (ParentDirectory NOT LIKE('C:DataProjectsBeaconVisual Studio 2005%')
AND ParentDirectory NOT LIKE('C:DataProjectsBeaconBeaconVisual Studio 2005%')
AND ParentDirectory NOT LIKE('C:DataProjectsBeaconPDAAuditPDAWM5%')
In a stored procedure I am trying to use a parameter in a where clause which is set dependent upon another parameter... ie if report 1 is run, I want to evaluate against the StartDate field ... otherwise evaluate against the EndDate field.
Hi, i have a stored procedure like this: CREATE PROCEDURE dbo.spQuery1
@dynamicField nvarchar(10)
AS
SELECT id, productName, productDescription
FROM products
WHERE @dynamicField = 'True'
RETURN The products table has id, productName, productDescription, property1, property2, property3 fields So my query variable should be, for example, "property1" and the result should be every row with "property1" set to true... but it doesnt work with the sql like this... any help?
I have a stored procedure which expects one parameter @Company The variable @Company holds pipe delimited value: "CNN|AOL|ABC"
I need to build a WHERE clause by parsing @Company value, so the select will look like below:
SELECT * FROM Company WHERE CompanyID IN (SELECT DISTINCT(CompanyID) FROM v_Company WHERE CompanyName = 'CNN') AND CompanyID IN (SELECT DISTINCT(CompanyID) FROM v_Company WHERE CompanyName = 'AOL') AND CompanyID IN (SELECT DISTINCT(CompanyID) FROM v_Company WHERE CompanyName = 'ABC')
I have 3 tables: Authors, Employee and Stores. I need to create a stored procedure which will take 3 comma delimited parameters, to be able to query above 3 tables. Basically my front end user can say give me Authors with last name starting from ‘A,B’ and Employee with first name starting from ‘J,N,K’ and Stores with city starting from ‘New, Los’. So, stored procedure call will look like this Exec myStoredProcedure 'A,B' , 'J,N,K', 'New,Los' .
My question is, how should I handle WHERE clause in stored procedure if I don’t want it to be a “dynamic WHERE�.
I have a project which is need dynamically t-sql clause...I've created interface for the create dynamic t-sql clause. But the clause should get data from relational database. It needs inner join...so it's very hard to do it..
for example
lkpProduct
id product 1 Mouse 2 Keyboard
3 Modem 4 Monitor
main
id productid
1 4 2 1 3 2 4 3 5 4
You can get this table with 2 ways like this..
1. Select main.id, lkpProduct.product from main,lkpProduct where main.productid = lkpProduct.id 2. Select id, case productid when 1 then 'Mouse'.....end as product from main
I have a stored procedure which expects one parameter @Company The variable @Company holds pipe delimited value: "CNN|AOL|ABC"
I need to build a WHERE clause by parsing @Company value, so the select will look like below:
SELECT * FROM Company WHERE CompanyName = 'CNN' AND CompanyName = 'AOL' AND CompanyName = 'ABC'
P.S I know that above select doesn€™t really make sense , but I have a bigger query that would be hard to explain in this topic so I just simplified it.
This fails with the error "cannot convert varchar to numeric". I believe since ColumnA is numeric, its trying to convert the dynamic paramter to numeric leading to the failure.
has someone implemented an In clause as a parameter? Please do not tell me that I can append the values as string and construct a dynamic query. I want to use a parameterized version. I will be calling this repeatedly and dont want recompile overhead.
I am trying rewrite an sp that I have that is considered dynamic cause it builds a where clause based on a bunch of if statements then adds it to the the end of select
i.e
if...@where = @where + ' llll '
if...@where = @where + ' llll '
select @statement = @statement + @where
exec(@statement)
I have rewritten most of it to but I have several conditions that use ' contains' for the condition and I can't get SQL server to recognize an if statement or a case statement.
Is it possible to use either statement inside a where clause??
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.
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.
I've search around quite extensively on the net and found a few examples that touch on this subject, but the only definitive one that seemed to solve this problem used a temp table in the UDF, which, to my knowledge, is impossible...
The problem is thus: I want to create either a stored procedure or a user defined function to return a list of values I can intersperse to use in a WHERE AccountID IN (<values>). This way, if someone were to create a new stored procedure and they wanted to either only select accounts with those IDs or perform a NOT IN and use it to filter.
The Solution I'm attempting: My idea is best represented in psuedo-code: - Create a Function that stores all account Ids we relate to a particular account type, in this case, let's say accountsids "100, 101, 102, 407" are all accounts we want to consider "cash". - The function would look something like: CREATE FUNCTION CashAccountIDs()
RETURNS TABLE
AS
BEGIN DECLARE TABLE @t1 (account INT) INSERT INTO @t1 VALUES (100) INSERT INTO @t1 VALUES (101) INSERT INTO @t1 VALUES (102) INSERT INTO @t1 VALUES (407) RETURN @t1 END
Then I could call this function by doing something such as:
SELECT * FROM Accounts WHERE AccountId IN (dbo.CashAccountIds())
I would presumably do this for other collections of accounts as well, so that I would end up with say 5 functions I could call to filter various types of accounts.
Not too certain if I am approaching this the correct way or not, I've been receiving a myriad of errors trying different methods. If I use the function above it tells me "Must declare @t1", so I modified it so @t1 is declared in the RETURNS statement, and the syntax checks then work, but when I attempt to save the function it tells me "Cannot perform alter on fn_cashaccountids because it is an incompatible object type"
(The code I use to generate this error is: CREATE FUNCTION fn_cashaccountids ()
RETURNS @t1 TABLE (i INT)
AS
BEGIN INSERT INTO @t1 VALUES (100) RETURN END
Hopefully I've provided enough but not too much info to sift through, it seems to me this would be something encountered a bit before.
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'

Anyone know how i should word the if...statements? I have not found anything that works yet. Thanks
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 use a DataGrid to show the data, and I want it has a sorting and Paging function, so I use dataset to collect the data from middle tier function and stored procedure. I have code in aspx page like BindData(ViewState("SortExpr")).

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 a.Model = IsNull(@Model,a.Model) AND a.Condition = IsNull(@Condition, a.Condition) AND dbo.DistanceAssistant(z.Latitude,z.Longitude,r.Latitude,r.Longitude) <= @Miles ORDER BY @SortExpr END ELSE SELECT -1 As ZIPCode --ZIP Code not found... GO
but I got the error as "variables are only allowed when ordering by an expression referenceing a column name". How I fix this error? Please help.
If I do this with a function and multiple inline sql statements, I could probably do it much easier, but here at work, sprocs are required, and I can't seem to stretch my knowledge and Google searches far enough to find the answer. Plus, I don't really think that creating 4 separate sProcs is the most efficient way of doing this I need to select and return 8 columns from a table, but the problem is I need to feed the sProc parameters in such a way, that I can use different criteria in the Where Clause. for instance, I need to combine these 4 select statements into one:1. Select (fields) from (table) Where TechID=@TechID and Status=@Status)2. Select (fields) from (table) Where TechID=@TechID3. Select (fields) from (table) Where OrdNum=@OrdNum3. Select (fields) from (table) Where CustNum=@CustNum In all instances, the fields and the table are the same - how can I combine all these possible Where clauses (if/then - Select Case?) so that it's only one Stored Procedure? (or, is this even possible?)
I am creating a dynamic query where i am appending a where clause something like -
IF (@CurCaptureDate IS NOT NULL) SET @where_clause = @where_clause + CHAR(10) + 'AND CD.CaptureDate = ' + @CurCaptureDate
PS - CD.CaptureDate is datetime and @CurCaptureDate is also datetime
but when executing , it gives this error - Msg 241, Level 16, State 1, Line 169 Conversion failed when converting date and/or time from character string.
i am not able to use convert here with these quotes.
i tried this - SET @where_clause = @where_clause + CHAR(10) + 'AND CD.CaptureDate = ' + CONVERT(VARCHAR(25),@CurCaptureDate )
but it makes it to -
AND CD.CaptureDate = Jul 19 2014 12:00AM. I would need the date in quotes.
I have to build a dynamic query to go over to Oracle and get some data and bring it back via a SQL Server Stored Procedure. How I can create an IN clause passing values and ","s from a SQL Server Temp Table that I have already built.
SET @SQLQuery = @SQLQuery + 'WHERE MEMBER.MEMBER_ID IN (''''' + SELECT MEMBER.MEMBER_ID + ',' FROM #TempTable + '''''Â '
I'm sending a stored procedure a number of parameters, including an int for a foreign key field. I'm trying to dynamically build the Where Clause of the query.
I'm getting the error:
Syntax error converting the varchar value 'wo_dutfk = ' to a column of data type int.
NOTE: wo_dutfk is an int field within the WO table.
The first select is running fine but due to extra values added to the table the list of manual difined columns must be added manualy each time new values occur.
Is it possible to make the PIVOT's IN clause dynamicly as stated in the second script (it is based on the same table #source) when running it prompts the next error;

Arvind writes "i want to create a stored procedure returns an OUTPUT variable containing the no. of records given by a query, the query being dynamic.

I have a quite big SQL query which would be nice to be used using UNION betweern two Select and Where clauses. I noticed that if both Select clauses have Where part between UNION other is ignored. How can I prevent this?
I found a article in StackOverflow saying that if UNION has e.g. two Selects with Where conditions other one will not work. [URL] ....
I have installed SQL Server 2014 and I tried to use tricks mentioned in StackOverflow's article but couldn't succeeded.
Any example how to write two Selects with own Where clauses and those Selects are joined with UNION?

I got your email address from your web cast. I really enjoyed the web cast and found it to be very informative.
Our company is planning to use SSIS (VS 2005 / SQL Server 2005). I have a quick question regarding the product. I have looked for the information on the web, but was not able to find relevant information.
We are getting Source data from two of our client in the form of Excel Sheet. These Excel sheets Are generated using reporting services. On examining the excel sheet, I found out that the name Of the columns contain data itself, so the names are not static such as Jan 2007 Sales, Feb 2007 Sales etc etc. And even the number of columns are not static. It depends upon the range of date selected by the user.
I wanted to know, if there is a way to import Excel sheet using Integration Services by defining the position Of column, instead of column name and I am not sure if there is a way for me to import excel with dynamic Number of columns.
Your help in this respect is highly appreciated!
Thanks,
Hi Anthony, I am glad the Web cast was helpful.
Kamal and I have both moved on to other teams in MSFT and I am a little rusty in that area, though in general dynamic numbers of columns in any format is always tricky. I am just assuming its not feasible for you to try and get the source for SSIS a little closer to home, e.g. rather than using Excel output from Reporting Services, use the same/some form of the query/data source that RS is using.
I suggest you post a question on the SSIS forum on MSDN and you should get some good answers. http://forums.microsoft.com/msdn/showforum.aspx?forumid=80&siteid=1 http://forums.microsoft.com/msdn/showforum.aspx?forumid=80&siteid=1
