Dynamic SQL And Function

Jul 20, 2005

Hi i have a problem i have the following Trans SQL statement in a
function

SET @desc= (Select description From table Where id = @id)

Now i want to make table dynamic. Something like this

SET @desc= (Select description From @table Where id = @id)

Yeah yeah i know i can't do this:

SET @desc= EXEC('Select description From '+ @table + ' Where id = '+
@id)
is not possible

Writing to a temporary table is prohibited by functions. But i need a
function because i want to use the result in a query..

Can someone help me?

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 β€“ 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

Dynamic Sql In Function Issue

May 7, 2008

i want to know if i can use dynamic sql in a function like this:



ALTER FUNCTION [dbo].[udf_GetGradeAvgByNewHireID]
@CourseIDs VARCHAR(MAX),
@NewHireID INT
)
RETURNS INT
AS
BEGIN

/*
1. The CourseIDs passed to this function will be in the form ",1,2,3,"
2. Replace the first and last comma with () so we will have "(1,2,3)"
3. Use this with the IN clause to filter out the right classes for these IDs
*/

DECLARE @SQL VARCHAR(MAX);

--grade average
DECLARE @GradeAvg INT;

--formatting the string to be in the form (1,2,3) from ,1,2,3,4,
SET @CourseIDs = '|' + @CourseIDs + '|';
SET @CourseIDs = REPLACE(@CourseIDs,'|,','(');
SET @CourseIDs = REPLACE(@CourseIDs,',|',')');

SET @SQL = 'SELECT @GradeAvg = AVG(NHC.Class_Grade)
FROM
New_Hires_Classes NHC
INNER JOIN Classes Cls ON NHC.Class_ID=Cls.Class_ID
WHERE Cls.Course_ID IN ' + @CourseIDs +
' AND NHC.New_Hire_ID=@NewHireID';
EXECUTE @SQL

RETURN @GradeAvg


becase when i try to call this function from the query i get this error:


The name 'SELECT @GradeAvg = AVG(NHC.Class_Grade)
FROM
New_Hires_Classes NHC
INNER JOIN Classes Cls ON NHC.Class_ID=Cls.Class_ID
WHERE Cls.Course_ID IN (1,2,3,4,5,6) AND NHC.New_Hire_ID=@NewHireID' is not a valid identifier.

A Function That Creates A View (dynamic SQL)

Jan 23, 2008

I'm very new to SQL Server. Please help. I need to create a FUNCTION that creates a view. Then call this function in a SQL which is passed as a parameter to BCP. In Oracle, it would be something like:



create function CREATEVIEW

return number as

begin

create view SampleView as SELECT a,b,c from Mytable;

return 1;

when others then return 0; -- for exception handling

end:



create function DROPVIEW

return number as

begin

Drop view SampleView;

return 1;

when others then return 0; -- for exception handling

end:



Then my BCP will have something like:



BCP "select CREATEVIEW from dual"... QUERYOUT ..



then

BCP "select * from SampleView"... QUERYOUT ..



then drop the view again:

BCP "select DROPVIEW from dual"... QUERYOUT ..



I know there is no DUAL table in SQL SERVER. I just want to know how to code this in SQL Server.

The origin of my problem is that my SQL statement is too long to fit as BCP parameter, hence, am creating a view and reading there and dropping it again. If you can provide me with a better workaround, that would be great.
Thanks in advance.

Dynamic Order Status Column Function

Apr 7, 2008

I am looking for assistance coming up with a function (or maybe not a function if there is a better way) to make the Status column in my order table dynamic. The default value for new records will always be "1" to designate a quote. At this point the field is not dynamic. Once the customer confirms the order, the user needs to execute a command to change the status to "3" to designate a Confirmed order. At this point the field needs to be dynamic based on the shipping records. There are two order details tables. One for sales items and one for rental items. Each of these details tables has their own shipping record. the CheckInOut Tables are for rental while the Ship tables are for sales. So, if some (but not all) of the items in either of these order details tables has a shipping record associated with it, then the status should be changed to "5". If everything has been shipping, the status is changed to "4". If everything has been shipping but some items have been returned, the status is "6" if everything has been shipping and all of the RentalDetail items have been returned then the status is "7" and if there is any other combination of a variety of ships and returns, the status is "8". Also, at any time, the user needs to be able to execute a command to change the value to "2". once the value is changed to "2" the field stops being dynamic again.

Below are my tables creation commands.


CREATE TABLE OrderHeader
(
OrderID int identity primary key,
Status int,
StartDate datetime,
EndDate datetime
)--Use Type 1 = "Quote" Type 2 = "Cancelled" Type 3 = "Confirmed", Type 4 = "Shipped", Type 5 = "Part Shipped", Type 6 = "Part Returned", Type 7 = "Returned, Type 8 = "Mixed"
CREATE TABLE OrderRentalDetail
(
OrderRentalDetailID int identity primary key,
OrderID int FOREIGN KEY REFERENCES OrderHeader(OrderID),
ItemName varchar(30),
Qty int,
SiteID int,
)
CREATE TABLE CheckInOutHeader
(
CheckInOutID int identity primary key,
Type int,
SiteID int,
ActionDate datetime
)--Use Type 1 = "Ship" Type 2 = "Return" Type 3 = "Lost"
CREATE TABLE CheckInOutDetail
(
CheckInOutDetailID int identity primary key,
CheckInOutID int NOT NULL FOREIGN KEY REFERENCES ShipHeader(ShippingID),
OrderRentalDetailID int,
Qty int
)
CREATE TABLE OrderSalesDetail
(
OrderSalesDetailID int identity primary key,
OrderID int FOREIGN KEY REFERENCES OrderHeader(OrderID),
ItemName varchar(30),
Qty int,
SiteID int,
)
CREATE TABLE ShipHeader
(
ShippingID int identity primary key,
Type int,
SiteID int,
ActionDate datetime
)--Use Type 1 = "Ship" Type 2 = "Return"
CREATE TABLE ShipDetail
(
ShipDetailID int identity primary key,
ShippingID int NOT NULL FOREIGN KEY REFERENCES ShipHeader(ShippingID),
OrderSalesDetailID int,
Qty int
)

Dynamic Query Calling User Defined Function

Apr 19, 2006

I have the following procedure, that calls a Padding function to pad characters to a field.

Here is what the procedure looks like

Code:

CREATE PROCEDURE [dbo].[Pad_Left]

@Table VARCHAR(255),
@Column VARCHAR(255),
@PadChar CHAR(1),
@PadToLen INT

AS

DECLARE @Query Varchar(5000)

SET @Query = 'UPDATE ' + @Table + '

SET ' + @Column + ' = dbo.Function_PadLeft(' + @Column + ', ''' + @PadChar + ''', ' + @PadToLen + ')'

EXECUTE(@Query)
GO



When I run this I get the error

Server: Msg 245, Level 16, State 1, Procedure Pad_Left, Line 13
Syntax error converting the varchar value 'UPDATE Lincoln

SET baths = dbo.Function_PadLeft(baths, '0', ' to a column of data type int.

But when I just run this query, it works


Code:

CREATE PROCEDURE [dbo].[Pad_Left]

@Table VARCHAR(255),
@Column VARCHAR(255),
@PadChar CHAR(1),
@PadToLen INT

AS

UPDATE Lincoln

SET Baths = dbo.Function_PadLeft(Baths, '0', 4)

GO



Why would one work but not the other? I don't understand, as they are the same thing, just one calls the function dynamically?

I must be missing something very obvious

Thanks for any help!

SQL Server 2012 :: Dynamic Return Type In A Function

Mar 3, 2015

I have created a function that will check whether the data is null or not. If its null then it will display that as No data else it will display the original value. Below is the function

GO
Object: UserDefinedFunction [dbo].[fnchkNull] Script Date: 3/4/2015 12:01:58 PM ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO

[code]...

The code is working good. However i want the return type to be dynamic. If the data type supplied is integer then i want to return a integer value like 0 if its null. if the data value is varchar then i want to return 'No Data'.

Importing Excel Sheet Which Have Dynamic Column Name And Dynamic Number Of Columns

Aug 25, 2007

Hi Craig/Kamal,

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.

SSRS 2005 - Email Report On Execution To Dynamic List With Dynamic Parameters = No Schedule

Nov 23, 2007

Hi,
I have a need to display on screen AND email a pdf report to email addresses specified at run time, executing the report with a parameter specified by the user. I have looked into data driven subscriptions, but it seems this is based on scheduling. Unfortunately for the majority of the project I will only have access to SQL 2005 Standard Edition (Production system is Enterprise), so I cannot investigate thoroughly.

So, is this possible using data driven subscriptions? Scenario is:

1. User enters parameter used for query, as well as email addresses.
2. Report is generated and displayed on screen.
3. Report is emailed to addresses specified by user.

Any tips on how to get this working?

Thanks

Merge Replication W/ Dynamic Row Filter - Not 'dynamic' After First Initial Sync?

May 2, 2007

If anyone could confirm...

SQL Server 2000 SP4 to multiple SQL Server 2005 Mobile Edition on PDAs. My DB on SQL2k is published with a single dynamic row filter using host_name() on my 'parent' table and also join filters from parent to child tables. The row filter uses joins to other tables elsewhere that are not published to evaluate what data is allowed through the filter.

E.g. Published parent table that contains suppliers names, etc. while child table is suppliers' products. The filter queries host_name(s) linked to suppliers in unpublished table elsewhere.

First initial sync with snapshot is correct and as I expected - PDA receives only the data from parent (and thus child tables) that matches the row filter for the host_name provided.

However - in my scenario host_name <--> suppliers may later be updated E.g. more suppliers assigned to a PDA for use or vice versa. But when I merge the mobile DB, the new data is not downloaded? Tried re-running snapshot, etc., no change.

Question: I thought the filters would remain dynamic and be applied on each sync?

I run a 'harmless' update on parent table using TSQL e.g. "update table set 'X' = 'X'" and re-sync. Now the new parent records are downloaded - but the child records are not!

Question: I wonder why if parent records are supplied, why not child records?

If I delete existing DB and sync new, I get the updated snapshot and all is well - until more data added back at server...

Any help would be greatly appreciated. Is it possible (or not) to have dynamic filters run during second or subsequent merge?

T-SQL (SS2K8) :: How To Add Inline TVF With Dynamic Columns From CRL Dynamic Pivot

Mixing Dynamic SQL With Non-Dynamic In Stored Proc

Mar 24, 2007

I have a Stored Procedure for processing a Bill of Material.

One column on the Assembly Table is a Function Name that contains some busniess rules.

OK, now I'm doing a Proof of Concept and I'm stumped.

Huuuuh!

I will ultimately have about 100 of these things. My plan was using Dynamic SQL to go execute the function.

Note: The function just returns a bit.

So; here's what I had in mind ...

if isnull(@FnNameYN,'') <> ''
exec spinb_CheckYN @FnNameYN, @InvLineID, @FnBit = @FnBit output




CREATE PROCEDURE dbo.spinb_CheckYN
@FnNameYN varchar(50),
@InvLineID int,
@FnBit bit output
AS

declare @SQL varchar(8000)

set @SQL = '
if dbo.' + @FnNameYN + ' (' + convert(varchar(31),@InvLineID) + ')) = 1
set @FnBit = 1
else
set @FnBit = 0'

exec (@SQL)
GO



Obviously; @FnBit is not defined in @SQL so that execution will not work.
Server: Msg 137, Level 15, State 1, Line 4
Must declare the variable '@FnBit'.
Server: Msg 137, Level 15, State 1, Line 5
Must declare the variable '@FnBit'.


So; is there a way to get a value out of a Dynamic SQL piece of code and get that value INTO my OUTPUT variable?


My many thanks to anyone who can solve this riddle for me.
Thank You!


Sigh: For now, it looks like I'll have a huge string of "IF" statements for each business rule function, as follows:
Hopefully a better solution comes to light.

------ Vertical Build1 - Std Vanes -----------
if @FnNameYN = 'fnb_YN_B1_14'
BEGIN
if dbo.fnb_YN_B1_14 (convert(varchar(31),@InvLineID) ) = 1
set @FnBit = 1
else
set @FnBit = 0
END

------ Vertical Build1 - Scissor Vanes -----------
if @FnNameYN = 'fnb_YN_B1_15'
BEGIN
if dbo.fnb_YN_B1_15 (convert(varchar(31),@InvLineID) ) = 1
set @FnBit = 1
else
set @FnBit = 0
END
.
.
.
etc.

Dynamic Source And Dynamic Destination

Apr 15, 2008

I have a requirment which i have partly accomplished , but could not get through completely

i have a file which comes in a standard format ending with date and seq number ,

suppose , the file name is abc_yyyymmdd_01 , for first copy , if it is copied more then once the sequence number changes to 02 and 03 and keep going on .

then i need to transform those in to new file comma delimited destination file with a name abc_yyyymmdd,txt and others counting file counting record abc_count_yyyymmdd.txt. and move it to a designated folder. and the source file is then moved to archived folder


what i have taken apprach is

script task select source file --------------------> data flow task------------------------------------------> script task to destination file

dataflow task -------------------------> does count and copy in delimited format



what is happening here is i can accomlish a regular source file convert it to delimited destination file --------> and move it to destination folder with script task .

but cannot work the dynamic pick of a source file.


please advise with your comments or solution you have

In-Line Table-Valued Function: How To Get The Result Out From The Function?

Dec 9, 2007

Hi all,

I executed the following sql script successfuuly:

shcInLineTableFN.sql:

USE pubs

GO

CREATE FUNCTION dbo.AuthorsForState(@cState char(2))

RETURNS TABLE

AS

RETURN (SELECT * FROM Authors WHERE state = @cState)

GO

And the "dbo.AuthorsForState" is in the Table-valued Functions, Programmabilty, pubs Database.

I tried to get the result out of the "dbo.AuthorsForState" by executing the following sql script:

shcInlineTableFNresult.sql:

USE pubs

GO

SELECT * FROM shcInLineTableFN

GO


I got the following error message:

Msg 208, Level 16, State 1, Line 1

Invalid object name 'shcInLineTableFN'.


Please help and advise me how to fix the syntax

"SELECT * FROM shcInLineTableFN"
and get the right table shown in the output.

Thanks in advance,

Pass Output Of A Function To Another Function As Input

Jan 7, 2014

I need to be able to pass the output of a function to another function as input, where all functions involved are user-defined in-line table-valued functions. I already posted this on Stack Exchange, so here is a link to the relevant code: [URL] ...

I am fairly certain OUTER APPLY is the core answer here; there's *clearly* some way in which does *not* do what I need, or I would not get the null output you see in the link, but it seems clear that there should be a way to fool it into working.

Dynamic Columns For Dynamic SQL

Mar 9, 2007

I have created a dynamic SQL program that returns a range of columns (1 -12) based on the date range the user may select. Each dynamic column is month based, however, the date range may overlap from one year to another. Thus, the beginning month for one selection may be October 2005, while another may have the beginning month of January 2007.

Basically, the dynamic SQL is a derived Pivot table. The problem that I need to resolve is how do I now use this dynamic result set in a Report. Please keep in mind that the name of the columns change based on the date range select.

I have come to understand that a dynamic anything is a moving target!



Please advise.

Using A Scalar Valued Function As A Parameter Of A Table Valued Function?

Feb 1, 2006

Ok, I'm pretty knowledgable about T-SQL, but I've hit something that seems should work, but just doesn't...
I'm writing a stored procedure that needs to use the primary key fields of a table that is being passed to me so that I can generate what will most likely be a dynamically generated SQL statement and then execute it.
So the first thing I do, is I need to grab the primary key fields of the table.  I'd rather not go down to the base system tables since we may (hopefully) upgrade this one SQL 2000 machine to 2005 fairly soon, so I poke around, and find sp_pkeys in the master table.  Great.  I pass in the table name, and sure enough, it comes back with a record set, 1 row per column.  That's exactly what I need.
Umm... This is the part where I'm at a loss.  The stored procedure outputs the resultset as a resultset (Not as an output param).  Now I want to use that list in my stored procedure, thinking that if the base tables change, Microsoft will change the stored procedure accordingly, so even after a version upgrade my stuff SHOULD still work.  But... How do I use the resultset from the stored procedure?  You can't reference it like a table-valued function, nor can you 'capture' the resultset for use using the  syntax like:
DECLARE @table table@table=EXEC sp_pkeys MyTable
That of course just returns you the RETURN_VALUE instead of the resultset it output.  Ugh.  Ok, so I finally decide to just bite the bullet, and I grab the code from sp_pkeys and make my own little function called fn_pkeys.  Since I might also want to be able to 'force' the primary keys (Maybe the table doesn't really have one, but logically it does), I decide it'll pass back a comma-delimited varchar of columns that make up the primary key.  Ok, I test it and it works great.
Now, I'm happily going along and building my routine, and realize, hey, I don't really want that in a comma-delimited varchar, I want to use it in one of my queries, and I have this nice little table-valued function I call split, that takes a comma-delimited varchar, and returns a table... So I preceed to try it out...
SELECT *FROM Split(fn_pkeys('MyTable'),DEFAULT)
Syntax Error.  Ugh.  Eventually, I even try:
SELECT *FROM Split(substring('abc,def',2,6),DEFAULT)
Syntax Error.
Hmm...What am I doing wrong here, or can't you use a scalar-valued function as a parameter into a table-valued function?
SELECT *FROM Split('bc,def',DEFAULT) works just fine.
So my questions are:
Is there any way to programmatically capture a resultset that is being output from a stored procedure for use in the stored procedure that called it?
Is there any way to pass a scalar-valued function as a parameter into a table-valued function?
Oh, this works as well as a work around, but I'm more interested in if there is a way without having to workaround:
DECLARE @tmp varchar(8000)
SET @tmp=(SELECT dbo.fn_pkeys('MyTable'))
SELECT *
FROM Split(@tmp,DEFAULT)

Calling A Function From A Function?

Apr 11, 2008

Hi All

Yesterday Peso was gracious enough to help me with creating function/views/sp's

I took those examples and extended what had from excel into function in SQL

however I see myself repeating certain parts of the query and i'm wondering if there is a way to call a function (in part or in whole) from another function?

Here are excerpts two functions I have:

We'll call this function UserUsage()
------------------------------------
RETURN(
SELECT ut.LastName, ut.FirstName,
CEILING(Sum(hu.session_time)/ 60000) AS [Time Spent(MIN)],
Max(hu.time_stamp) AS [Last Log Date],
pct.Title, cat.topic_name
FROM ZSRIVENDEL.dbo.UserTable ut,
ZSRIVENDEL.dbo.history_usage hu,
ZSRIVENDEL.dbo.pc_CourseTitles pct,
ZSRIVENDEL.dbo.cam_topics cat
WHERE ut.student_id = hu.student_id
AND hu.course_id = pct.CourseID
AND hu.topic_id = cat.topic_id
AND ((ut.ClientID=@ClientID)
AND (pct.ClientID=@ClientID)
AND (ut.GroupID=3400)
AND (hu.time_stamp>= @StartDate
And hu.time_stamp< @EndDate)
AND (hu.session_time<21600000))
GROUP BY ut.LastName, ut.FirstName, pct.Title, cat.topic_name
)

and will call this function UserSummary():
-----------------------------------------
RETURN (
SELECTut.LastName, ut.FirstName,
CEILING(SUM(hu.Session_Time) / 60000.0) AS [Time Spent(MIN)]
FROM ZSRIVENDEL.dbo.UserTable AS ut
INNER JOIN ZSRIVENDEL.dbo.History_Usage AS hu
ON hu.Student_ID = ut.Student_ID
WHERE ut.ClientID = @ClientID
AND ut.GroupID = 3400
AND hu.Time_Stamp >= @StartDate
AND hu.Time_Stamp < @EndDate
AND hu.Session_Time < 21600000
GROUP BY ut.LastName, ut.FirstName
)

As you can see the first part of the both query are simlar. In particular the:

SELECTut.LastName, ut.FirstName,
CEILING(SUM(hu.Session_Time) / 60000.0) AS [Time Spent(MIN)]

and also the variables @StartDate and @EndDate.

In C# it would create a method and just call that method as well as the variables. However i'm not sure how to do that with sql functions. Could someone shed some light please?

Thank you!

Dynamic SQL

Sep 21, 2007

I need to pass all values of field of a table into a parameter. My table contains a field called typeID, there are 15 typeID in the table. Currently when a user choses a single type they see a report for that type. I want to give them the ability to run a report on all types. My thinking is that I should just be able to pass all typeID values into a string and pass it to the stored Proc... but being new at sql and this truley being the first thing I have ever done in it... I am missing the mark.
Param is @TypeID
Here is the sql to exec the stored proc:USE [db]
GODECLARE @return_value int
EXEC @return_value = [dbo].[OL]
@TypeID = 2,SELECT 'Return Value' = @return_value
GO
 
I know this is not the actual SP, I am just trying to get it to work, then I will be able to write the proc. It should be something like @Option = 1 AND 2 or 1 & 2 or something to that nature?
