Lookup To Check Values In 13 Columns With Same Values
Mar 22, 2006
hi,
it is my first post on this forum, please be patient if i miss any important bit of information.
i am transporting data from a legacy system into mssql 2k5 using SSIS.
among those column of a dataset there are 13 columns, all necessary for operational reasons, that i need to ensure data consistance.
i believe i could do this check using the lookup data flow item, but surely there must be a way to do it in a more streamlined fashion.
since column names contain numbers to distinguish the version, eg; col01, col02, col03 .. col13.
i thought i could include the lookup within a loop and use a couple of variables to do this trick, but since i have not done it before i am asking for some sort of guidance from a guru among you folks.
please let me know if further clarification is necessary.
regards,
nicolas

Hello all,
I am trying to think my way through a solution which I believe others have probably come across... I am trying to implement a matching routine wherein I need to match an address against a high value and a low value (or, for that matter an input date vs. a start and end date) to return the desired row ... i.e. if I were to use a straight vb program I would just use the following lookup:
"SELECT DISTINCT fire_id, police_ID, fire_opt_in_out, police_opt_in_out FROM ipt_tbl " & _
" WHERE zip_code = @zip_code AND addr_prim_lo <= @street_number AND addr_prim_hi >= @street_number " & _
" AND addr_prim_oe = @addr_prim_oe AND street_pre = @street_pre AND street_name = @street_name " & _
" AND street_suff = @street_suff AND street_post = @street_post " & _
" AND (expiry_date = '' OR expiry_date = '00000000' OR expiry_date > @expiry_date)" & _
" GROUP BY fire_ID, police_ID, fire_opt_in_out, police_opt_in_out"
My question, then, is how would you perform this type of query using a lookup / merge join or script? I have not found a way to implement a way to set the input columns? I can set the straight matches without a problem, i.e. lookup zip code = input zip code, but can't think of the correct way to set comparisons, i.e. lookup value 1 <= input value AND lookup value 2 >= input value
Any suggestions?
thanks for your time...

I have a situation in SSRS to get the common values between the two columns where the values are sorted comma separated as below.Ex:
ColumnA :  abc,cde,efg  Â
ColumnB : cde,xyz,abc  Â
the result in  Â
ColumnC : cde,abc
similarly Column A and B will have n number records. I need to right an expression or the Code function to get the required result in ColumnC. I am using SharePoint Lists as Datasource. Cannot write SQL query to achieve this requirement.

I've got some records like this:
ID_________Jan Feb...........................Dec
0000030257 0 0 0 0 0 0 1 1 1 1 1 0
where each month field has a 0 or 1, depending on if the person was enrolled that month.
I'm being asked to generate a table like this:
ID_________ Start_Date End_Date
0000030257 July 1, 2014 Nov 30, 2014
Is there some slam dunk way to do this without a bunch of If/Then statements?
The editor compressed all my space fields, so the column headers are off in some places.

I am relatively new to SQL and as a project I have been asked to create the SQL for a simple database to record train details. I want to implement a check constraint which will prevent data from being inserted into a table if the weight of the train is more than the maximum towing weight of the locomotive. FOr instance, I need to add the unladen weight and maximum capacity of each wagon (located in the wagon type table) and compare it against the locomotive maximum pulling weight (the locomotive class table). I have the following SQL but it will not work:
check((select SUM(fwt.unladen_weight+fwt.maximum_payload) from
hauls as h,freight_wagon as fw,freight_wagon_type as fwt,train as t where
h.freight_wagon_serial_number = fw.freight_wagon_serial_number and
fw.freight_wagon_type = fwt.freight_wagon_type and
h.train_number = t.train_number) <
(select lc.maximum_towing_weight from locomotive_class as lc,locomotive as l,train as t where
lc.locomotive_class = l.locomotive_class and l.locomotive_serial_number = t.locomotive_serial_number))
The hauls table is where the constraint has been placed and is the intermediary table between train and freight wagon.
I may not have explained this very well; but in short, i need to compare the sum of two values in one table against a values located in another table...At present I keep getting a message telling me the sub query cannot return more than one row.

Folks,My secnario involves two tables - ObservationRegister, and Person.ObservationRegister contains most of the "useful" fields, includingthe UserID of the person that raised the record, and the UserID of theperson to whom the record was assigned for action. I need to write aquery to return all values in the ObservationRegister record, butinstead of returning the UserIDs, I need to look up the actual name,by looking up the name and userID in the Person table... doing thatonce (for just one of the UserID fields) is easy - a quick inner joindoes the job - but I effectively need to join to the Person table"twice", for different keys....Help? Please!? :)Steve

I need some help with the following...
My data source has some columns I have to 'translate' first and then insert into my destination table.
Example Source data:
key size height
1 'Small' 'Tall'
2 'Big' 'Short'
has to become
1 'Y' 'P'
2 'N' 'D'
I thought of creating a lookup table (I'm talking about the real table, not a lookup transformation table) that would have these columns: column name, value_source, value_dest
Example:
col_name vl_source vl_dest
size 'Small' 'Y'
size 'Big' 'N'
height 'Tall' 'P'
... and so on, I believe you get the point
How would you extract the needed values? Can I use a select statement in a derived column expression? Any ideas? I'm not really fond of the idea to create n lookups, one for each column I have to translate, is there a slicker solution?

Hi,
Can you please tell me the way to configure the LOOK UP transformation so that it will ignore all the null values ? I want to configure a Look up component for the column "Col1" as follows
All the NULL values of Col1 should not be considered for look-up process. They should be passed to the downstream component as valid rows.
All NOT NULL values of Col1 should be processed by the Look up component.
If there is no matching value present for any NOT NULL value of Col1 then it should be directed to error output.
Regards,
Gopi

Hi,
I have a data flow task and trying to transform datas OLTP to STG db and i have lookup tables.
I do lookuping like this
first a lookup that lookup my table with connected input column parameter
second a derived column is connected to lookup's error output for when lookup can't find the value and this derived column returned "0" or "-1" this means that lookuped value can't find and insert this value to my table
third a union that union lookup and derived column
i want to ask this is there any different solution for doing this, because if i more than 5 or 6 lookup in my ssis package i add all of them derived columns and unions and when i change something i have to change or correct the unions step by step.
thanks

I have 2 datasets, dataseta is a list of tickets and their relevant owner and databsetb is a list of owners and a days worked first against them.I have a table with a detail grouping on ticketid and a normal grouping on owner which works well... all straight forward to this point. In this table on the owner grouping level I also have a lookup to datasetb which pulls back the days worked per owner which works fine as well. But what I now need to do is total the days worked over all owners, which sounds simple but doesn't work. This is the expression on the days worked for each owner -
=lookup (Fields!owner. Value, Fields!owner.Value, Fields!Days_worked.Value,"datasetb")
If I add a sum around this then it uses the figure above but multiplies it by the amount of tickets in the detail grouping.

I am using Visual Web Developer Express 2005 and SQL Server Express 2005.
I have set up a trigger that fires when an update has been performed on a specific table. The trigger checks to see if specific columns have been updated. If they have, then the trigger code is executed. This part works fine.
I am now trying to find a way to check if null values exist in either one of two field from the same table. If either field contains a null value, then I don't want the trigger code to be executed.
How can I check for null values and skip a block of code within my Transact Sql trigger.
Thanks.....

Hey all,
I was wondering what the best method of checking on page_load if a datasource control is pulling back nothing from a database. I want to display a message explaining that there is no data to be displayed. How would I go about doing that? I have tried searching google and whatnot but didn't find anything really helpful.
Here is the current code for the data source control.
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|EventInsider.mdf;Integrated Security=True;User Instance=True"
ProviderName="System.Data.SqlClient" SelectCommand="SELECT Events_Groups.GroupName, Events_Groups.GroupID FROM Events_GroupMembership INNER JOIN Events_Groups ON Events_GroupMembership.GroupID = Events_Groups.GroupID WHERE (Events_GroupMembership.UserID = @UserID)">
<SelectParameters>
<asp:SessionParameter Name="UserID" SessionField="UserID" />
</SelectParameters>
</asp:SqlDataSource>
But I have no idea what the code behind would be to check it on page_load. If there is no way to particularly do this, do you have to do it per control? Like dropdownbox's or gridviews? I am just confused on how to check to make sure there is data to be displayed.
Thanks,
Chris

say i have a table, and in it are two columns, column1 and column2 and i do the following query:
SELECT column1, column2 FROM table WHERE column2 = '12345'
i want to check if column1 has all the same values, so in the first case, no
column1 column2
------- --------
4 12345
9 12345
5 12345
column1 column2
------- --------
9 12345
9 12345
9 12345
in the 2nd case, column1 contains all the same values, so yes
is there anyway i can check this? i would be doing this in a trigger.. say when a new row is inserted, the value of column1 is inserted, but col 2 is null.. so when they try to fill in the value for col2 of that row, the trigger checks to see if the value they put for col 2 is already in the table.. if it isn't, then everything is ok. but if it is already in teh table, then it checks col1 to see if all the values of col1 are the same
i hope this makes sense
thanks

I'm pretty new to sql server and now I need to create a script that:
Compares the values of the row with the same id as the row with the update table(which has updated values in it) in which the price, description or replacement part have been changed.
If they did change they should be updated and if they haven't been changed nothing should happen...

Hi All,
I have a table Saleshistory with 89481412 records. I have a field Sales of nvarchar type, all the records in this field are numeric, and the records are with 2 decimal places. I expect all the records to be ending at .00 (for example 5.00,345.00,25.00), but I want to verify if something is for example 5.6 etc.
So in short I want to check if any Salesrecords have more than zero values in the decimal. How can I check this.
Please help.
Thanks,

Hi all,
I wanted to check the previous and next record values.
For example:
sKey NextKey PreviousKey
1 2 Null
2 8 1
8 5 2
5 null 8
Ex : In the first record of the table, the NextKey is pointing to 2.
So the next record of Skey will be 2. The Next Key for this record is 8. Like wise the next record of this should have the Skey as 8.
Now I need to check whether the NextKey and SKey are correct for all rows.
For that I need to check the previous record of "Next key" and next record of "Skey".
Any idea?
Regards
Helen

UNION ALL SELECT 5060, '05/02/2015','13:30', '15:30'
[Code] ....
The results from the above are as follows:
columnAcolumnB SampleTitle1 SampleTitle2 SampleTitle3 SampleTitle4

How do i verify all of the columns one after the other .
I am after the statement like this dynamically
-- IF NOT (@col1 = '') THEN set @SQL = @SQL + '[col1] = ' + @col1 + ' '
--IF NOT (@col2 = '') THEN set @SQL = @SQL + '[col2] = ' + @col2 + ' '
I need to check if the columns are blank or not dynamically as i do not want to hard code the column names there.

I have never used triggers before and I have tried to solve one problem. If I have the column "currency" in a table and want to make sure that the entered value i valid in relation to another table that contains valid currency formats, I did it like this:
---------------------------------
CREATE TRIGGER [trigger_checkCurrency] ON [dbo].[Client]
FOR INSERT, UPDATE
AS
declare @currency as char(50)
declare @country as char(50)
declare cur cursor for SELECT currency, country
FROMinserted
OPEN cur
fetch cur into @currency, @country
WHILE @@FETCH_STATUS = 0
BEGIN
if not exists(select * from listinfoid where listname = 'currency' and listid = @currency)
begin
set @currency = (cast(@currency as varchar (3)) + ' is not a valid currency')
CLOSE cur
DEALLOCATE cur
RAISERROR (@currency,16,-1) with log
return
end
if not exists(select * from listinfoid where listname = 'country' and listid = @country)
begin
set @country = (cast(@country as varchar (3)) + ' is not a valid contry')
CLOSE cur
DEALLOCATE cur
RAISERROR (@country,16,-1) with log
return
end
else
fetch cur into @currency, @country
END
CLOSE cur
DEALLOCATE cur
update Client set currency = UPPER(currency), country = UPPER(country)
---------------------------------
I use a cursor to handle multiple rows in an update query.
(SQL2000-server)
Is there an easier och better way to do this?
I´m a bit unsure of this code.
Thanx!

I know how to check for a sinle vlaue but how do I chekc to see if multiple values exist. I need to check for certain email addresses from a list that I have.
Let us say I ahve 3 email addresses, I want to check for all of them in a table and for eevery email address that is present I want to print something like "You email address is XXX" and if one of those 3 is not found my results should look like
"You email address is XXX"
YYYYY not found
"You email address is ZZZZ"
I'm attaching some TSQL that I tried on [AdventureWorks2012].[Person].[EmailAddress]
/****** Select ALL if where an email address is present in the list ******/
SELECT EmailAddressID,EmailAddress
FROM [AdventureWorks2012].[Person].[EmailAddress]
WHERE EmailAddress IN
(
'ken0@adventure-works.com', --1
'terri0@adventure-works.com', --2
[Code] ....
-- Test to see if a single email address is present
IF EXISTS
(
SELECT EmailAddress FROM [AdventureWorks2012].[Person].[EmailAddress]
WHERE EmailAddress IN ('25rob0@adventure-works.com')
)
BEGIN
SELECT 'Email address is presnt'
[Code] ....
When I check multiples using EXISTS it works as per its design and says YES even if a single item is present.

Hi I want to find 3 different columns maximum values in one shot. Like I tried to use a reader to go through results but it kept coming back with index out of bounds. Right now to get it to work I got to use a ExecuteScalar() get the first columns max value and then open the connection again(since it seems after ExecuteScalar() it closes the connection) and then do the ExecuteScalar() again. Open the connection again and do the ExecuteScalar() again. Theres got to be a better way of doing this.

Hi,
The values I need to store in the table are
Student ID
Student Name
Subjects
The "Student ID" is the primary key.
A student can take more than 1 subject.
For example:
Student ID: 100
Student Name: Kelly Preston
Subjects: Geography, History, Math
How can I store these values in a database table?
I know the normal "INSERT" statement, but how would I store the multiple subjects for a single student ID?
My "Student ID" is auto generated. If I create a new row for each subject, the Student ID will be different for each subject, which I dont want.
Or I can create a new field called "RowNumber" and keep that the primary key..
For example:
Row Number StudentID StudentName Subject
1 100 Kelly Geography
2 100 Kelly History
3 100 Kelly Math
If this is the only way to store the multiple sibjects, then for a given student ID (say 100), how can I retreieve the associated name and subjects? What is the query for that?
