SSIS Dynamic Columns in SQL

Hi All
I have an unusual issue and wondered if someone could assist. have a table which contains a list of columns which i need to feed into the query. I have written some dynamic SQL as shown:
Declare @KeyString varchar(100)
Declare @SQL1 nvarchar(max)
Set @KeyString=(Select STUFF((SELECT '+' + Attr FROM ave_control.ETL.Source inner JOIN [DM_AVE2].[Reference].[CRKAttr] on client = sourcename COLLATE DATABASE_DEFAULT where Client = 'Brampton' Order by AttrOrder FOR XML PATH('')),1,1,'') AS KeyString)
Set @SQL1 ='WITH CLAIMDATA AS(

I always want to output @Keystring using a DFT but depending on the client the Keystring is set to a different group of columns and selects a different set of columns from the CLAIMRCData loop.
I tried inserting it as dynamic SQL as a variable but cannot get it to parse - does anyone know how to achieve this?
Here is the output from the Select @SQL1 which always returns the value I want and if i execute this and change the clientname it successfully returns the right claimkey each time - i.e. another client has 3 columns and these are successfully parsed
- i just dont know how to get it into SSIS. Output as shown:

any help would be greatly appreciated - oh version is SQL 2014 SSIS
Thanks

When you say not able to parse, can you give the expression itself?
And in what SSIS component do you run this query?
And what error do you get?
My cursory look (too much code to digest frankly) says you need to wrap it into a stored procedure.

Dynamic column name sql?

I need to do a select statement using dynamic column names. Can it be done WITHOUT building a string to execute the sql?
In other words, I want to use a variable name in the SELECT part of a statement.
Thanks

Properly done, there shouldn't be a great difference in the performance of static and dynamic SQL. Of course, dynamic SQL is a whole lot more complicated to get right. It's also rather at odds with your requirement that column names get passed in dynamically-- if you don't know what columns you're going to select at compile time, you can't use static SQL.
That said, there are a handful of tricks around using Oracle's built-in XML processing functionality to simulate dynamic SQL. This is almost certainly less efficient than doing dynamic SQL in your case, and a whole lot more complicated, but it's technically not dynamic SQL.
The proper response, though, is almost certainly to either
1) figure out how to design the application so that column names need not be passed in at runtime or
2) use dynamic SQL.
If at all possible, option 1 is generally preferable. While there are situations where dynamic SQL is necessary, those tend to be rather rare.

Here i Want to Generate Date column value Dynamically.....................is it possible through SQL
the values are Sales value for each showroom for diffrent date value
all sale,showroom and Date Column are in one Table......................
It should Generate date Dynamically depending on User VAlues./..............
Thanks in Advance

something to play with (not tested as I don't have database access)
declare
/* assuming table showroom_sales has columns a_showroom,a_date,a_sale */
the_sql varchar2(32000) := 'select a_showroom';
day_from date := to_date('20090101','yyyymmdd');
day_till date := to_date('20090107','yyyymmdd');
begin
for d in (select a_date from showroom_sales where a_date between day_from and day_till)
loop
    the_sql := the_sql ||
               ',max(decode(a_date,to_date('''||to_char(d.a_date,'yyyymmdd')||''',''yyyymmdd''),a_sale,null)) "'||to_char(d.a_date,'dd-mm-rr')||'"'
end loop;
the_sql := the_sql || ' from showroom_sales group by a_showroom order by a_showroom ';
dbms_output.put_line(the_sql); /* to verify if query is correct or not */
end;the code above should generate something like (provided all those dates appear in your showroom_sales table)
select a_showroom,
       max(decode(a_date,to_date('20090101','yyyymmdd'),a_sale,null)) "01-01-09",
       max(decode(a_date,to_date('20090102','yyyymmdd'),a_sale,null)) "02-01-09",
       max(decode(a_date,to_date('20090103','yyyymmdd'),a_sale,null)) "03-01-09",
       max(decode(a_date,to_date('20090104','yyyymmdd'),a_sale,null)) "04-01-09",
       max(decode(a_date,to_date('20090105','yyyymmdd'),a_sale,null)) "05-01-09",
       max(decode(a_date,to_date('20090106','yyyymmdd'),a_sale,null)) "06-01-09",
       max(decode(a_date,to_date('20090107','yyyymmdd'),a_sale,null)) "07-01-09"
from showroom_sales

Dynamic Column in SQL-Statement

Hello,
can i do something like this?
SELECT :P101_Lang FROM LANGUAGE where NAME = 'P5_REPORT'
Many thanks in advance

I have a similar situation, but rather than a select statement, it's an update statement. I'm still VERY new to APEX and Oracle SQL. I'm used to using MS Access & VBA, but the project that was handed to me is APEX, so I'm doing my best to learn it.
Page Items:
P4_COLUMN_NAMES (Listbox)
P4_TEXT ENTRY (text field)
P4_ITEM_ENTRY (List management)
The process that should happen is this: User picks several items from ITEM_ENTRY, then chooses which column to update in COLUMN_NAMES to whatever is in TEXT_ENTRY.
Using the APEX function to cycle through the ITEM_ENTRY results, I've tried SEVERAL ways, all of which resulted in multiple errors. I've spent over a week, off and on, on this issue. Here is the most basic version.
declarev_p1_x_arr apex_application_global.vc_arr2;
begin
v_p1_x_arr := apex_util.string_to_table(:P4_ITEM_ENTRY);
for i in 1..v_p1_x_arr.count loop
UPDATE SMT SET :P4_COLUMN_NAMES = :P4_TEXT_ENTRY
end loop;
end;>
I've tried this as an app process and a page process. Until I found this thread, I didn't even know there was a PL/SQL region. ((told ya I'm a newbie)) It seems like the solution you provided to the other person is pretty close to what I'm looking for. However, I don't know how to implement it with the APEX function above.
Any help would be GREATLY appreciated!
Thanks,

Converting Oracle TIMESTAMP(4) column to SQL datetime column conversion error in ssis

I could not able to convert Oracle TIMESTAMP(4) column to SQL datetime column conversion error in ssis.
I'm connecting OLEDD Oracle Source to OLEDB SQL Destination in SSIS package. I'm trying to insert data from oracle datetime column into sql datetime column. I'm getting some errors.
Please provide helpful info.

You can transform the data types directly at the source by writing a proper SQL statement, or you can convert them using the data conversion component.

How to change recordset bahaviour to accept dynamic column names in the where clause

Hi
im using php-mysql and i make a recordset and i want to make the column names in the where clause to be dynamic like
"select id,name from mytable where $tablename-$myvar";
but when i do this my i break the recordset and it disappear
and when i use variables from advanced recordset it only dynamic for the value of the column not for the column name
and when i write the column name to dynamic as above by hand it truns a red exclamation mark on the server behaviour panel
so i think the only way is to change the recordset behaviour is it? if so How to make it accept dynamic column names?
thanks in advance.

As bregent has already explained to you, customizing the recordset code will result in Dreamweaver no longer recognizing the server behavior. This isn't a problem, but it does mean that you need to lay out your dynamic text with the Bindings panel before making any changes. Once you have changed the recordset code, the Bindings panel will no longer recognize the recordset fields.
Using a variable to choose a column name is quite simple, but you need to take some security measures to ensure that the value passed through the query string isn't attempting SQL injection. An effective way of doing this is to create an array of acceptable column names, and check that the value matches.
// create array of acceptable values
$valid = array('column_name1', 'column_name2', 'column_name3');
// if the query string contains an acceptable column name, use it
if (isset($_GET['colname']) && in_array($_GET['colname'], $valid)) {
$col = $GET['colname'];
} else {
// set a default value if the submitted one was invalid
$col = 'column_name1'
You can then use $col directly in the SQL query.

How many columns a sql selects

I need to find out how many columns are in a sql statement like below:
sql = "select id, decode(description,'','No decription', description), comment from my_table";
The sql string is build dynamically so I don't know it when I write the code. I need to know before I do
call rs.next(), because I need to set up the table header so I need to know how many columns the sql is selecting.
Thanks inadvance.
Botao

You can use the interface ResultSetMetaData,below are some methods of it.
int getColumnCount()
Returns the number of columns in this ResultSet object.
String getColumnName(int column)
Get the designated column's name.
int getColumnType(int column)
Retrieves the designated column's SQL type.
for more infomation ,you can refer to JDBC Online Document.

Please follow basic Netiquette and post the DDL we need to answer this. Follow industry and ANSI/ISO standards in your data. You should follow ISO-11179 rules for naming data elements. You should follow ISO-8601 rules for displaying temporal data. We need
to know the data types, keys and constraints on the table. Avoid dialect in favor of ANSI/ISO Standard SQL. And you need to read and download the PDF for:

>> I need to select from a dynamic column name and save the result in a variable, but seem to be having trouble with the values being fed to sp_executesql <<
This is so very, very wrong! A column is an attribute of an entity. The idea that you are so screwed up that you have no idea if you want
the shoe size, the phone number or something else at run time of this entity.
In Software Engineering we have a principle called cohesion that says a model should do one and only one task, have one and only one entry point, and one and only one exit point.
Hey, on a scale from 1 to 10, what color is your favorite letter of the alphabet? Yes, your mindset is that level of sillyity and absurdity.
Do you know that SQL is a declarative language? This family of languages does not use local variables!
Now think about “month_val” and what it means. A month is a temporal unit of measurement, so this is as silly as saying “liter_val” in your code. Why did you use “sp_” on a procedure? It has special meaning in T-SQL.
Think about how silly this is:
SET @month_val = 'Month' + CAST(@month_nbr AS VARCHAR(2));
We do not do display formatting in a query. This is a violation of at the tiered architecture principle. We have a presentation layer. But more than that, the INTERVAL temporal data type is a {year-month} and never just a month. This is fundamental.
We need to see the DDL so we can re-write this mess. Want to fix it or not?

Importing From Flat File with Dynamic Columns

HI
I am using ssis 2008,i have folder in which I have Four(4) “.txt” files each file will have 2 columns(ID, NAME). I loaded 4
files in one destination, but today I receive one more “.txt” file here we have 3 columns (ID, NAME, JOB) how can I get a message new column will receive in source. And how can I create in extra column in my destination table dynamically …please help me

Hi Sasidhar,
You need a Script Task to read the names and number of columns in the first row of the flat file each time and store it in a variable, then create a staging table dynamically based on this variable and modify the destination table definition if one ore more
new columns need to be added, and then use the staging table to load the destination table. I am afraid there is no available working script for your scenario, and you need some .NET coding experience to achieve your goal. Here is an example you can refer

Dynamic column selection

I want to select specific columns from a table dynamically which are basically the columns returned by quering the user_tab_columns data dictionary which in turn has to satisfy certain condition for me.
So, what I want to do is something like:
SELECT b.(dynamic column list from a)
FROM b,
(SELECT column_name FROM user_tab_columns WHERE table_name='STH' AND ........) a
any help will be greatly appreciated.

10      v_sql := v_sql || r.column_name || ',';
11    end loop;
12    v_sql := rtrim(v_sql, ',') || ' from emp';
13    dbms_output.put_line( v_sql );

Set label of an item dynamically through pl/sql function

Hi ,
How Can I get the label of an item dynamically through a pl/sql function.
I have a table that stores the label name for these items.
I want to set the label for the item based on the value in my table ?
Is it possible ?
any ideas ?
Thanks in advance,
Dippy

If I understand you correctly, you are using a standard report region, but want to dynamically name the column headers? The only way I've been able to get this to work is to create hidden items for each column header, calculate the value you want for each item, then reference the item in the column header using &item_X. for the column header name.
The problem is that at this point, APEX doesn't allow for dynamic column naming unless you want to do everything yourself using a PL/SQL process that builds the report table manually. I've done that for certain complex reporting tools.
I understand it's tedious to create all the column header items; I have one report that has over 72 items used in this way. It was a pain, but it got the job done.

Dynamic column heading in csv export not working

Hi,
I have a SQL report where the column headings are defined dynamically. for an example let's say I have a report
SELECT NAME, TODAY'S_DATE FROM TABLE A.
Under report attribute column I have defined column heading as "&P_todays_date.”. This item has source value “Select sysdate from dual. When I export the data into csv file the dynamic column headings are coming as blank.
Any suggestions?
Thanks,
Manish

Dynamic column names in Oracle

HI SOS!! calling for help...
i am trying to query the following. I want to remove the duplicates in the ID, and combine them into one... While doing so, I want to keep the data as it is by creating dynamic columns reason_1, reason_2, reason_3 with their corresponding TIME. In case of same reasons, I want to add the TIME. The database is as follows:
ID     REASON     TIME
A     41A..........     27
A     93K..........16
B     89C...........3
B     93K...........7
B     48C..........     4
C     93K..........     24
C     93K..........     7
C     48C.........10
Expected Result is
ID     REASON_1......TIME_1.... REASON_2...TIME_2....REASON_3.........TIME_3
A........ 41A............ 27........... 93K............16
B........ 89C............ 3............ 93K............7...........48C.................. 4
C........ 93K........... 31.......... 48C..............10
Would be grateful if someone could try helping me out of this as early as possible.

You still haven't made it clear what the requirement is.
Is there a maximum number of reasons that can occur per ID? If so, you can code the pivoting of your data with something like:
SQL> ed
Wrote file afiedt.buf
1 with t as (select 'A' as ID, '41A' as reason, 27 as time from dual union all
2             select 'A', '93K', 16 from dual union all
3             select 'B', '89C', 3 from dual union all
4             select 'B', '93K', 7 from dual union all
5             select 'B', '48C', 4 from dual union all
6             select 'C', '93K', 24 from dual union all
7             select 'C', '93K', 7 from dual union all
8             select 'C', '48C', 10 from dual)
9 --
10 -- END OF TEST DATA TABLE SIMULATED USING 'WITH' CLAUSE
11 -- SIMPLY USE THE SELECT STATEMENT BELOW ON YOUR OWN TABLE
12 --
13 select id
14        ,max(decode(rn,1,reason)) as reason_1
15        ,max(decode(rn,1,time)) as time_1
16        ,max(decode(rn,2,reason)) as reason_2
17        ,max(decode(rn,2,time)) as time_2
18        ,max(decode(rn,3,reason)) as reason_3
19        ,max(decode(rn,3,time)) as time_3
20        ,max(decode(rn,4,reason)) as reason_4
21        ,max(decode(rn,4,time)) as time_4
22        ,max(decode(rn,5,reason)) as reason_5
23        ,max(decode(rn,5,time)) as time_5
24 from (/* assign some row numbers within each ID, ordering by 'reason' then 'time' */
25        select id, reason, time
26              ,row_number() over (partition by id order by reason, time) as rn
27        from   t
28       )
29* group by id
SQL> /
I REA     TIME_1 REA     TIME_2 REA     TIME_3 REA     TIME_4 REA     TIME_5
A 41A         27 93K         16
B 48C          4 89C          3 93K          7
C 48C         10 93K          7 93K         24In this example, it will cater for up to 5 reasons/times per ID... and you can code for more if you need very easily.
Also, as you're using 11g, you can use the new PIVOT query, for which you can find plenty of examples if you google or search these forums, or follow the FAQ link.
If you don't have any idea how many reasons there could be, then you really are looking at generating columns dynamically.
The problem with that is, because Oracle needs to know the SQL projection (see the FAQ link already provided), it has to know how many columns are going to be returned from a query before any data is fetched... but you are saying that the columns returned have to be based on the data itself. To do that you have two main options:
1) You query the data once to determine how many columns you are going to need and then dynamically build up a query in PL/SQL code with the right number of columns (or use one of the other dynamic methods shown in the FAQ)
or
2) You step back and ask yourself if SQL is really the best place to be trying to produce this output. Reporting tools are often better suited to this requirement as they are made to query the data back from a database and then pivot and layout the data based on the data returned.
