Dynamic WHERE Clause Alternative.

Jun 26, 2007

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�.

Thank you

Alternative For The LIMIT Clause

Aug 9, 2004

Hello,

What do you do if you need to select item 20 to 40 from a table? Do you just do 1 to 40 and let PHP ignore the first 20, or do you have another equivalent of the MySQL LIMIT Clause for MSSQL?

Alternative To Dynamic Sql?

Jul 20, 2005

I have a procedure that take several paramters and depending of whatvalues is submitted or not, the procedures shall return differentnumber of rows. But to simplyfy this my example use just oneparameter, for example Idnr.If this id is submitted then I will return only the posts with thisidnr, but if this is not submitted, I will return all posts in table.As I can see I have two options1. IF @lcIdNr IS NOT NULLSELECT *FROM tableWHERE idnr = @lcIdNrELSESELECT *FROM table2. Use dynamic SQL.The first example can work with just one parameter but with a coupleof different input paramters this could be difficult, anyway this isnot a good solution. The second example works fine but as I understanddynamic sql is not good from the optimizing point of view. So, I don'twant to use either of theese options, so I wonder If there i a way towork around this with for example a case clause?RegardsJenny

Alternative To Dynamic SQL In A Function

Jan 14, 2008

Hi all, I have a sql problem i'd like to put to the masses because its driving me crazy! Before I start, this is a database i inherited so I cant change the schema.
I have a table which holds field information for a form, namely the table name, column name and some other irrelevant stuff (X/Y coordinates for printing onto a document). Here is some sample data to explain better:
TableName              FieldName                Xpos             Ypos
----------               ---------                -----            -----
FruitTable                FruitName                10                20
VegTable                 VegName                 10                40
FruitTable                FruitColour               20                10  
(Thats not the real data of course)
What I need is a calculated field which returns the value of each field from each table – probably by constructing a dynamic sql statement(?) It would look something like this:
Select @FieldName From @TableName Where bla bla bla â€“ don’t worry about the where clause. The completed dataset will hopefully then look like this:
TableName              FieldName                Xpos             Ypos             FieldValue (calculated field)
----------               ---------                -----            -----            ---------      
FruitTable                FruitName                10                20                Oranges (result of: Select FruitName From FruitTable Where....)
VegTable                 VegName                 10                40                Parsnips (result of: Select VegName From VegTable Where....)
FruitTable                FruitColour               20                10                Green (result of: Select FruitColour From FruitTable Where....)
 
I have tried creating a scalar-valued function which takes TableName and FieldName as parameters and creates a dynamic sql string, but i cannot seem to execute the sql once I have built it. Here is a general idea of how I was trying to use the function:
Main query:Select
TableName, FieldName, Xpos, Ypos,
dbo.GetFieldValue(TableName, FieldName) As FieldValue
From
tblFieldAndPosition---------------Function: CREATE FUNCTION GetFieldValue (@TableName nvarchar(255),@FieldName nvarchar(255))

RETURNS nvarchar(255)
AS
BEGIN

Declare @SQL nvarchar(max)
Set @SQL = 'Select ' + @FieldName + ' From ' + @TableName

sp_executesql @SQL??

return ???

END ------------------------- The alternative to getting this data all out at once is contructing the sql statement in code and going back to the database once for every row - which i really dont want to do. If anyone has had a situation like this before, or can point me in the right direction I will be very very grateful.  Hope thats clear. Thanks in advance

Column Name As Parameter Dynamic Sql Alternative

Feb 11, 2008

I am unfortunately lumered with a table I cannot edit that stores a division 2 characters along with boolean fields '0506', '0607', '0708' ... (academic years) to represent if that particular division is active in the current academic year. This has made me have to resort to dynamic sql within a stored procedure to input the appropriate field names.

Is there a better way to do it, it's not mission critical to make it not use dynamic sql but I would prefer not to.

Using Dynamic IN Clause

May 9, 2007

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.

Need Help With Dynamic Where Clause

Jul 19, 2007

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



thanks for any suggestions provided.

Dynamic 'where' Clause

Nov 13, 2006

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.

Dynamic WHERE Clause

Dec 6, 2007

Hi all,

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'')

Dynamic Where Clause

Aug 23, 2007

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 -

set @sql = N'declare @p1 nvarchar(10),
@p2 nvarchar(10);
set @p1 = ''' + @parsedValue1 + ''', @p2 = ''' + @parsedValue2 + '''; ' +

N'select col1 from table1 ' + @whereCondition

exec (@sql)

(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.

Any advice would be appreciated.

Can I do this using Sql (Sql Compact 3.0)?

Dynamic Where Clause

Mar 10, 2008

Hi

I'm using SQL Server 2000...

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.

declare @StartDt datetime;
declare @EndDt datetime;
declare @WhereDate varchar(30);

if @report = 1 then
begin

set @WhereDate = 'Table.EndDate'
end
else set @WhereDate = 'Table.StartDate'

select *
from MyTable
Where @WhereDate >= @StartDt and @WhereDate < @EndDt


I'm getting syntax errors, so my question is.... is it possible... if so what syntax should I use?

Cheers

How To Create Dynamic T-SQL Clause

May 6, 2008

Hi,


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

mytable

id product
1 Monitor
2 Mouse
3 Keyboard
4 Modem
5 Monitor


My question is; how can i use CASE function dynamically ?? Mouse should get from lkpProduct....I do not want to write long table manually..

I hope it is clear for you..

Regards.

Parameterized IN Clause In Dynamic SQL

Nov 16, 2007

Hi,

I am trying to build a parameterized query where I pass a set of integer values into the dynamic sql. Please see below example.

DECLARE @SQLQUERY NVARCHAR(4000)
DECLARE @PARAMDEF NVARCHAR(1000)
DECLARE @VALUES VARCHAR(100)

SET @PARAMDEF = N'@IN_VAL VARCHAR(100)'

SET @VALUES = '1,2,3,4'

SET @SQLQUERY = 'SELECT * FROM TABLEA WHERE COLUMNA IN (@IN_VAL)'

EXEC SP_EXECUTESQL @SQLQUERY,@PARAMDEF,@IN_VAL=@VALUES

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.

TIA

Dynamic Where Clause With If..else Or Case

Jun 13, 2006

Hello all...

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??

i.e

where if a = 1 then d=e

else contains(.....)



thanks

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.

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.

Using A UDF To Return Values For A Dynamic WHERE IN () Clause

Mar 2, 2006

Greetings,

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.

Any help is very much appreciated.

Highly Dynamic Where Clause In A Stored Procedure

Apr 23, 2008

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!

Stored Procedure With Optional/dynamic Where Clause

Apr 21, 2006

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?)

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.

Transact SQL :: Dynamic Query And Formulating IN Clause

May 7, 2015

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 + ''''' '

Dynamic Built Where Clause - Error In Stored Procedure

Mar 2, 2005

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.

Here's the code:

CREATE PROCEDURE dbo.ewo_sp_WOLookup
(
@WODUTFK int=NULL,
@WOENDDATE datetime = NULL,
@WOSTATUS char(10) = NULL,
@DEBUG int=0
)

AS

Declare @intErrorCode int,
@chvQuery varchar (8000),
@chvWhere varchar (8000)

select @intErrorCode = @@ERROR,
@chvQuery='SET QUOTED_IDENTIFIER OFF select * from WO',
@chvWhere=''


-- DUT is specified
If @intErrorCode = 0 and @WODUTFK is not NULL
Begin
set @chvWhere = @chvWhere + 'wo_dutfk = '+@WODUTFK
End



IF @intErrorCode=0 and Len(@chvWhere)>0
Begin
set @chvQuery = @chvQuery + ' WHERE ' + @chvWhere
select @intErrorCode=@@ERROR
END

IF @DEBUG<>0
select @chvQuery Query

IF @intErrorCode=0
Begin
exec (@chvQuery)
select @intErrorCode=@@ERROR
End

return @intErrorCode

GO
---

Any suggestions on how to fix?

Thanks,

peter

SQL Server 2014 :: Pivot IN Clause - Dynamic Columns

May 12, 2015

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;

Msg 156, Level 15, State 1, Line 315
Incorrect syntax near the keyword 'select'.
Msg 102, Level 15, State 1, Line 315
Incorrect syntax near ')'.

adding or moving ')' or '(' are not working.......

select *
into #temp
from #source
pivot ( avg(value) for drive in ([C], [D], [E], [F], [G], [H], [T], [U], [V] )) as value
select * from #temp order by .........

versus

select *
into #temp
from #source
pivot ( avg(value) for drive in (select distinct(column) from #source)) as value

select * from #temp order by .....

OUTPUT @count =no Of Records Returnd By Dynamic Where Clause

Aug 18, 2005

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.
Preferrably the query should also be passed as a parameter to the stored procedure...If not,it should be constructed in the SP and a Part of the where clause is dependant on the value of another variable passed to the SP.

How should the query be constructed, executed, and then the Count(*) value returned?

"WHERE <condition1> AND <condition 2> ;


"AND <condition 2> " may exist or may not exist in the query; it is dependant."
