Dynamic (on The Fly) Query

Jun 20, 2006

Hi all.  I'm currently encountering a problem in attempting to find a solution for a dynamic or on the fly query.  I understand how you can make a static query and return it as a dataset; for example, say you have a field where a user enters a name on the front end and the db returns the results:
Dim queryString As String = "SELECT [Table].* FROM [Table] WHERE ("& _                                "[Table].[Name] = @Name)"
But what if I have multiple items I would like query based upon what the user picks.  For example, say you have five fields: Name, ID Number, Date, Address, and State.  Say the user wants to pick all data with a date between Jan. 06 to April 06, with the name of Tom, and in the state of CA.  But then next time, the user only wants all data with the name of Susan.  So the query is always changing and I am not sure exactly how to go about it.  I guess I sorta want similiar functionality as that of the Custom Auto Filter in Excel.  I've been reading a couple of the forums and I think people are using a string to pass to query the database.  But I am still vague on how to approach this.  Any help would be greatly appreciated!

Dynamic Query

Sep 14, 2007

I am having trouble wrapping my head around some dynamic queries.  I have x number of queries stored in a table.  Each row in this table has a From, Join, and Where column.  So, for x=3, I can run the query from each row so that I may have
Q1:  (1, 2, 4, 5, 7, 8)
Q2:  (1, 3, 5, 7, 9)
Q3:  (2, 4, 6, 8, 10)
I need to use these queries to generate a shared table: |-------------------|
| ID | Q1 | Q2 | Q3 |
| 1 | 1 | 1 | 0 |
| 2 | 1 | 0 | 1 |
| 3 | 0 | 1 | 0 |
| 4 | 1 | 0 | 1 |
| 5 | 1 | 1 | 0 |
| 6 | 0 | 0 | 1 |
| 7 | 1 | 1 | 0 |
| 8 | 1 | 0 | 1 |
| 9 | 0 | 1 | 0 |
| 10 | 0 | 0 | 1 |
|-------------------| I'm not sure the best way to do this.  I think that doing it on the asp.net side will be easier than in t-sql, although I am exploring both possibilities.  Any suggestions?

I want to create a report which uses a query that has a dynamic "in" list.
something like

"syntax error converting the nvarchar value '1,2,3' to a column of data type int'.

any workarounds?

Regarding Dynamic Query...

May 15, 2005

Hi,
 I have basic design question regarding dynamic query,
When we have to build a dynamic query (which has table name also as an input parameter),
->Is it better to write a stored procedure ..?
or
->directly specify the dynamic query and set the command type as text in .NET code...?
 
I think,since dynamic queries may not have the advantage of precompliation, it may not yield any performance in using SP's in such case..
 
Please through some light on this,
TIA

Dynamic Query Or Non Dynamic Query

Jan 4, 2001

Hi

I have two options two write queries one Static & one Dynamic.
I wanted to know which one will be good.

Example

if @x = 1
Select * From Customers order by CustomerID
Else IF @x = 2
Select * From Customers Order by CustomerName
Else IF @X = 3
Select * From Customers Order by city
else..
...


Against this
Set @Strsql = "Select * From Customers order by " + @Orderby
Exec (@Strsql)

Which will have better performance ?
Is SQL Stores query plans for static queries with all if statements clause
or it remains as good as dynamic ?

Thanks,
Manoj

Dynamic Query :: HELP!

Oct 19, 2004

I'm the new guy and I could use a hand. Any insight would be appreciated.

Basically my task is to create a dynamic way to merge columns from multiple rows. Way the table is set up data is imported and one entry may be up to 3 rows one column from each row can be merged to form a long description, I would like to create a view that would allow you to dynamically query this data and have the description be merged in the result set.

row1 x y z
row2 x b z
row3 x m z


results should look like :: x, (y + b + m) , z


Thank you in advance for any help you can provide!

Dynamic Query

Oct 7, 2006

month wise production

Format that I want

item codenameJulyAugSepOctNovDecjan

1002pvc resin 3020115060140
3501SWR pipe566045801002020




I create crosstab procedure as follows

create procedure up_CrossTab (@SelectStatement varchar(1000),
@PivotColumn varchar(100),
@Summary varchar(100),
@GroupbyField varchar(100),
@OtherColumns varchar(100) = Null)
AS
/*
Inputs are any 1000 character or less valid SELECT sql statement,
the name of the column to pivot (transform to rows), the instructions to summarize the data, the field you want to group on, and other fields returned as output. 1
*/
set nocount on
set ansi_warnings off

declare @Values varchar(8000);
set @Values = '';

set @OtherColumns= isNull(', ' + @OtherColumns,'')
/*
An 8000 varchar variable called @values is created to hold the [potentially filtered] values in the pivot column. @Values is initiated to an empty string. Then, a temporary table is created to hold each unique value. After the table is created, its rows are loaded into the variable @values. It's usefullness completed, the temporary table is destroyed. 2
*/
create table #temp (Tempfield varchar(100))

insert into #temp
exec ('select distinct convert(varchar(100),' + @PivotColumn + ') as Tempfield FROM (' + @SelectStatement + ') A')

select @Values = @Values + ', ' +
replace(replace(@Summary,'(','(CASE WHEN ' + @PivotColumn + '=''' +
Tempfield + ''' THEN '),')[', ' END) as [' + Tempfield )
from #Temp
order by Tempfield

drop table #Temp
/*
Finally, a dynamic sql select statement is executed which takes the GroupByField, and OtherColumns, passed into the procedure, and each of the Values from the Pivot Column from the passed in SELECT statement . 3
*/
exec ( 'select ' + @GroupbyField + @OtherColumns + @Values +
' from (' + @SelectStatement + ') A GROUP BY ' + @GroupbyField)

set nocount off
set ansi_warnings on
GO


And then my sql query is as like


EXEC up_CrossTab 'SELECT ProdId, GrnDate,Quantity FROM inteacc..IcGrnD IcGrnD
INNER JOIN inteacc..IcProduct IcProduct ON (IcGrnD.ProdId=IcProduct.ProdId) ',
'Year(GrnDate)', 'sum(Quantity)[]', 'ProdId'




error occurring


ambiguous column name ‘ProdId’




But when I compile this query

EXEC up_CrossTab 'SELECT grnNo,GrnDate,Quantity FROM inteacc..IcGrnD IcGrnD
INNER JOIN inteacc..IcProduct IcProduct ON (IcGrnD.ProdId=IcProduct.ProdId) ',
'Month(GrnDate)', 'sum(Quantity)[]','GrnNo'


Output


GrnNo12249
1220NullNull20
2Null20Null10
3NullNull300Null
4NullNull10Null



I could not understand the error.

What will I do to get the format I want?

Dynamic SQL Query Question

Jul 4, 2007

I am so sorry if I posted this to the wrong forum, here is my dilemma and I am hoping someone can point me.I have a SQL query such as this... SELECT tblNode, tblCorp, tblService FROM tblName WHERE tblNode = @tblNode AND tblCorp = @tblCorp AND tblService = @tblServiceThe @tblNode, @tblCorp, @tblService are all pulling from 3 separate drop down controls. Ok easy enough.However, I want the drop downs to default to "ALL" and I want all records pulled. Or if only tblCorp and tblNode is done, I want all tblServices.Does this make sense? How can I do this with 1 single SQL String without having to build 27 separate queries and a case statement to get the same result?I guess I am looking to see if a wild card can be used so tblNode = % or something. The server is MSSQLThank you

UDF That Runs A Dynamic Query

Mar 11, 2008

Good afternoon,
i'm new to Functions on the SQL server

I'm trying to create a dynamic query that would select the the column passed to the function from a certain table

my table called selected_Date, and has StartDate, and EndDate columns

when the user select for example "StartDate", i pass this as a variable to the function which runs the query. but i always gets back the passed string as a result..

here is my table

StartDate | EndDate
---------------------
20071231 | 20080306


here is my function knowing that i'm passing "Start" as a variable:


Code:

ALTER FUNCTION tu_efgn_int.Get_StartEndDates(@DateType varchar(10))
RETURNS varchar(8)
AS
BEGIN
DECLARE @vDate varchar(15)

Set @vDate= (Select @DateType + 'Date' From dbo.ps_tbl_SelectedDates)

RETURN @vDate
END



@vDate always returns "StartDate" as result instead of 20071231 why is that ?

Dynamic Query Problem

Jan 5, 2007

I have a sproc that runs as a job every day. Since the first of the year, it hasn't been running properly (it errors out). It builds an SQL statement dynamically, and then executes it.

If I try to run it with QA, I get the following message:
Server: Msg 170, Level 15, State 1, Line 1
Line 1: Incorrect syntax near 'FCST'.
UPDATE OPSPLAN SET Jan_07=Jan_fcst, Feb_07=Feb_fcst, ...

However, if I just copy the entire Update statement contained in the error message into the QA window, and execute it, it runs just fine.

What could I be missing?


UPDATE OPSPLAN SET Jan_07=Jan_fcst, Feb_07=Feb_fcst, Mar_07=Mar_fcst,
Apr_07=Apr_fcst, May_07=May_fcst, Jun_07=Jun_fcst, Jul_07=Jul_fcst,
Aug_07=Aug_fcst, Sep_07=Sep_fcst, Oct_07=Oct_fcst, Nov_07=Nov_fcst,
Dec_07=Dec_fcst

Jan_fcst, Feb_fcst, Mar_fcst, Apr_fcst, May_fcst, Jun_fcst, Jul_fcst,
Aug_fcst, Sep_fcst, Oct_fcst, Nov_fcst, Dec_fcst

Dynamic Query Enhancement

May 13, 2008

The following dynamic query returns a list of tables some of which do not have records in them. Can someone help me out, I am trying to exclude the tables with no records returned? Also, I want to exclude tables where there is not a rn_create_user or rn_edit_user defined in the table?

DECLARE @TableName sysname, @Sql varchar(8000)

SELECT @TableName=MIN(TABLE_NAME)
FROM INFORMATION_SCHEMA.TABLES

WHILE @TableName IS NOT NULL
BEGIN
SELECT @Sql='select o.*
from ' + @TableName +

)'

Dynamic Query In WHERE Condition

Sep 10, 2014

I do have a table type as input

---------------------------
num|columnname|value

1|Name|3X5900
2|employeeID|null
3|JOD|null
4|Address|null

From this I have to form the where clause like "Name like'3X5900' ".This will be dynamic , as the search may vary on the next call for search.

How I have to implement this dynamic query in the below mentioned code.I have add the dynamic query where i have mentioned as '---- Where clause has to be added '. Sometime the table input will be having all the value for search. How I can implement this in my query with good performance.

DECLARE @Where varchar(4000);
Select @where = 'v.Name LIKE ''3X5900'''
SELECT * from
(SELECT Row_number()Over(Order By V.ProjectId) Rownum,

DTS W/dynamic Source && Query

Jul 20, 2005

I'm looking for a way to transform the contents of n source tablesinto a single destination table. This by itself is no problem.However, the name of the source tables change, so I'll need to basethe transform task on a global variable that I can update via externalcode. Not sure how to do that. I'm ok with executing the package 10times if there's 10 source tables.The last unknown piece is modifying the query used for the transform.There are 10 columns in the source table, but there are 12 columns inthe destination table. I must provide the 2 missing columns. They willsimply contain a year and month, ie. 05 2003.I'm taking a bunch of source tables (for a given month and year) androlling them together into one destination table, and carrying overthe month and year. I assume the month and year would also be globals.But I'm not sure how to incorporate them into the transform task sinceit wants strict SQL syntax.Any help is appreciated, thanks in advance!

Dynamic SELECT Query

May 21, 2008

I need to implement a "dynamic" select query, in which I want that the type and the number of columns are variable/changeable. For example using the parameters of a stored procedures. I would have a client code (written in VB .NET) in which I would choose the columns that I want to display in a DataGridView.


How should I modify the SELECT line or the SP in general to solve the problem??


The code I need to modify is this:



Code Snippet
CREATE PROCEDURE uspSelect1
@iDataInit datetime = '01 gen 1753',
@iDataEnd datetime = '31 dic 9999',
@iArticle nvarchar(50) = N'%',
@iMachineNum smallint,
@iTypeMaterial nvarchar(50) = N'%',
@iNominalCount float,
@iOperator nvarchar(50) = N'%',
@iCustomer varchar(50) = N'%',
@iComments nvarchar(1000) = N'%',
@iLanguage nvarchar(50) = N'%'
AS
SELECT i.IDsample, i.Date, i.Article, i.MachineNum, i.TypeMaterial, i.NominalCount, i.Operator, i.Customer, i.Comments, i.Language, r.Um, r.CVm
FROM Identification i JOIN Reports r
ON (i.IDsample = r.IDsample)
WHERE i.Date BETWEEN @iDataInit AND @iDataEnd
AND i.Article LIKE @iArticle
AND i.MachineNum = ISNULL(@iMachineNum, i.MachineNum)
AND i.TypeMaterial LIKE @iTypeMaterial
AND i.NominalCount = ISNULL(@iNominalCount, i.NominalCount)
AND i.Operator LIKE @iOperator
AND i.Customer LIKE @iCustomer
AND i.Comments LIKE @iComments
AND i.Language LIKE @iLanguage
ORDER BY i.IDsample


Thank you.

Using EXISTS With Dynamic Query

Sep 21, 2007

In a SP I need to know if certain records already exist
but the query is parameter dependent so I can't code
IF EXISTS (SELECT ...)
because the proper select must be calculated.
Using
EXEC (@CalculatedQuery)
IF @@ROWCOUNT = 0
Puts the results of @CalculatedQuery into my SP result set.
This is highly undesireable.
