Hello,
I have few columns at some level, and now I need to add a column from another database table based on the values from one of the existing columns.
It seems that Lookup Transformation doesnt support parameterized query.
Any clue ?
Thanks
Fahad
I have added a new column to a table, but it is not showing up in the column mapping tab of the lookup editor.
It does show up in the preview.
Without deleting and recreating the component (with all the ensuing broken metadata fixes 'downstream' that this always entails), how can I get it to recognise the change?
In future I will do all LUs as a sql statement so at least I can control columns. This again defeats the purpose of the drag and drop environment..... If it were a harry potter character, it would be a dementor
I am looking for the best way in SSIS to do the following. I have an SQL table that for each row in the table I want to take an element from the table do a lookup in a Teredata Table, return information from the teredata source. Use that returned data to do some calculations and create a derived column from my calculations and place the data into the same SQL table that I am parsing through.
Ideas?
I am trying a create views that would join 2 tables:
Table 1: Has all the columns need by a view (
Name: Product
Structure: ID, Attribute 1, Attribute 2, Attribute 3, Attribute 4, Attribute 5 etc
Table 2: Is a lookup table that provides the names of columns
Name: lookupTable
Structure: tableName, ColumnName, columnValue
Values: Product, Attribute1, Color
Product, Attribute2, Size
Product, Attribute3, Flavor
Product, Attribute4, Shape
I want to create a view that looks like
ID, Color, Size, Flavor, Shape
We did some "at scale" fuzzy lookup tests today and were rather disappointed with the performance. I'm wanting to know your experience so I can set my performance expectations appropriately.
We were doing a fuzzy lookup against a lookup table with 25 million rows. Each row has 11 columns used in the fuzzy lookup, each between 10-100 chars. We set CopyReferenceTable=0 and MatchIndexOptions=GenerateAndPersistNewIndex and WarmCaches=true. It took about 60 minutes to build that index table, during which, dtexec got up to 4.5GB memory usage. (Is there a way to tell what % of the index table got cached in memory? Memory kept rising as each "Finished building X% of fuzzy index" progress event scrolled by all the way up to 100% progress when it peaked at 4.5GB.) The MaxMemoryUsage setting we left blank so it would use as much as possible on this 64-bit box with 16GB of memory (but only about 4GB was available for SSIS).
After it got done building the index table, it started flowing data through the pipeline. We saw the first buffer of ~9,000 rows get passed from the source to the fuzzy lookup transform. Six hours later it had not finished doing the fuzzy lookup on that first buffer!!! Running profiler showed us it was firing off lots of singelton SQL queries doing lookups as expected. So it was making progress, just very, very slowly.
We had set MinSimilarity=0.45 and Exhaustive=False. Those seemed to be reasonable settings for smaller datasets.
Does that performance seem inline with expectations? Any thoughts to improve performance?
I am stuck on finding a solution to transpose source data from a system via a metadata look-up table into a destination table. I need a method to transpose/pivot the source data into columns (which are by various data-types). The datatypes for each column are listed in a metadata table.
Source Data Table:
Table Name: Source
SrcID AGE City Date
01 32 London 01-01-2013
02 35 Lagos 02-01-2013
03 36 NY 03-01-2013
Metadata Table:
Table Name:Metadata
MetaID Column_Name Column_type
11 AGE col_integer
22 City col_character
33 Date col_date
Destination table:
The source data to be loaded into the destination table(as shown below):
Table Name: Destination
SrcID MetaID col_int col_char col_date
01 11 32 - -
01 22 - London -
01 33 - - 01-01-2013
02 11 35 - -
02 22 - Lagos -
02 33 - - 02-01-2013
03 11 36 - -
03 22 - NY -
03 33 - - 03-01-2013
Does anyone have a clue as to why DT_R4, DT_R8 are not allowed as join columns? This means I cannot join tables on AccountNumbers, InvoiceNumbers, etc. What a pain...
View 3 Replies View RelatedHi,
I have a table t1 and t2 with following structure.
t1(
ID1 int IDENTITY PRIMARY KEY,
name1 varchar(20),
addr1 varchar(20)
)
t2(
ID2 int IDENTITY PRIMARY KEY,
name2 varchar(20),
addr2 varchar(20)
)
Objective here is to match name1 and name2 column using fuzzy look up. So, I used t1 as source table and t2 as reference/lookup table and mapped name1 and name2 column in Fuzzy look up editor. As output column I selected "ID2" column from t2.
Now when i run the package, it throws error
"Multiple identity columns specified for table '##FLRef_070522_14:16:39_5064_c1c6cbbd-5a54-4e36-9154-1371118f0931'. Only one identity column per table is allowed."
I suppose that during Fuzzy lookup, SSIS internally created temporary table and thats where this error occurs when adding two columns as identity. Can someone help me in resolving this issue.
Thanks
Sid
PS: I need ID2 column as output for further calculation.
My simplistic data model looks like this:
Table.1
Spread Product Sales Channel ..
2 x CB ..
2 y CB …
4 x GFR ..
4 y GFR ..
I need a column with Spread Mapping, which should look like this:
->There are more columns in data model.
-> Spread for GFR is wrong so it must be mapped to be able to compare with CB
I guess there should be calculated column formula to calculate Spread Mapping. How to do it?
Hello,I have a query that I need help with.there are two tables...Product- ProductId- Property1- Property2- Property3PropertyType- PropertyTypeId- PropertyTypeThere many columns in (Product) that reverence 1 lookup table (PropertyType)In the table Product, the columns Property1, Property2, Property3 all contain a numerical value that references PropertyType.PropertyTypeIdHow do I select a Product so I get all rows from Product and also the PropertyType that corresponds to the Product.Property1, Product.Property2, and Product.Property3ProductId | Property1 | Property2 | Property3 | PropertyType1 | PropertyType2 | PropertyType3 PropertyType(1) = PropertyType for Property1PropertyType(2) = PropertyType for Property2PropertyType(3) = PropertyType for Property3I hope this makes sence.Thanks in advance.

Hello,
I have created SSIS package programmatically, I want to add Lookup transformation,
How can I add column from reference dataset to the transformation?
I have try to add new output column but it gives me an validation error, I write following coed to add new output column to lookup.
IDTSOutputColumn90 outputColumn = this.lookup.OutputCollection[0].OutputColumnCollection.New();
outputColumn.Name = col.Name;
outputColumn.Description = "Staging table output";
outputColumn.TruncationRowDisposition = DTSRowDisposition.RD_FailComponent;
outputColumn.ErrorOrTruncationOperation = "Copy Column";
outputColumn.SetDataTypeProperties(col.DataType, col.Length, col.Precision, col.Scale, col.CodePage);
Please suggest other way to add column from reference dataset to transformation output.
In a calculated column I am trying to get a scalar text value from a lookup to another table. This works quite well when getting numerical values with the following formula:
=MinX(Filter(LookUpTable;LookupTable[from]<=MySourceTable[Day] && LookupTable[to]>=MySourceTable[Day]);LookUpTable[numericalColumn])
But as soon as I substitute the numerical column by a string column, #error results.
I also want to mention that the above query yields only one row as a result. It should be simple to return the value of one of the columns but after searching for quite some time, I could not find any function for that.
My report has two data sets that hold inventory from two different departments.
ds_DeptA and ds_DeptB
I have a table, that pulls the DeptB status of DeptA record and displays it. This returns empty when the lookup fails to make a match, which is fine. Typically means DeptB does not have the record yet. I need to count these empty (null) feilds and populate it in a Text box outside of the table.
I just can't figure out the syntax with multiple datasets. I can't use the lookup expression as part of the count expression since the count expression is not contained in a table that has a dataset.
table: ds_DeptA
fields:
ID
Name
date_set_to_DeptB
<<Expr>> =Lookup(Fields!ID.Value,Fields!DeptA_ID.Value,Fields!DeptB_Status.Value, "ds_DeptB")
I'm currently loading a package that does a lookup on a column of data type nvarchar(4).The values itself are (A+, A, B+, B, C, D, /). The strange lookup behaviour is happening for each of the cases, so it's not related to a specific value. After trying to put the cache on NO CACHE, the lookup works perfectly. When using the default FULL CACHE the strange behaviour happens. Could it be related to the data type? I have not yet tried to use a CHAR instead of a NVARCHAR but it looks like people have similar issues using CHAR.
View 2 Replies View RelatedI'm working with an existing package that uses the fuzzy lookup transform. The package is currently working; however, I need to add some columns to the lookup columns from the reference table that is being used.
It seems that I am hitting a memory threshold of some sort, as when I add 3 or 4 columns, the package works, but when I add 5 columns, the fuzzy lookup transform fails pre-execute:
Pre-Execute
Taking a snapshot of the reference table
Taking a snapshot of the reference table
Building Fuzzy Match Index
component "Fuzzy Lookup Existing Member" (8351) failed the pre-execute phase and returned error code 0x8007007A.
These errors occur regardless of what columns I am attempting to add to the lookup list.
I have tried setting the MaxMemoryUsage custom property of the transform to 0, and to explicit values that should be much more than enough to hold the fuzzy match index (the reference table is only about 3000 rows, and the entire table is stored in less than 2MB of disk space.
Any ideas on what else could be causing this?

I'm designing a database for my final year project at University, and have run into a bit of a dilemma with one of the tables. Basically, it's an equipment loan database where both students and lecturers need to be able to book and borrow equipment. To avoid having two separate bookings tables (i.e. StudentBookings and LecturerBookings) I've got students and lecturers combined into one table called 'Borrowers'. The trouble comes because the clients want the lecturer storing in the booking information table, which can get quite messy because lecturer information is stored in the same table as borrower information meaning that I basically need to relate both the Booking.BorrowerID and Booking.LecturerID to Borrowers.BorrowerID.
In theory, I think this could be solved by creating a View called Lecturers that pulls the required information for Lecturers out of the Borrowers table and then link Booking.LecturerID to the ID of the view. In practice, I've got a couple of queries:
1) Is it possible to perform a JOIN on a view in the way that I would need to here?
2) To keep things nice and clear, is it possible to 'rename' the BorrowerID to LecturerID whilst creating the View?
Sorry if some of this isn't too clear. Please ask any questions to clarify what I mean if you need to.
Cheers
Jon
Hi,
I'm inserting records into a Table1 with the following fields :
tabID int 4ClientID int 4..etc etc.
In the insertitem template, I want the user to enter a Clientcode into textbox1. Then I want that client code validated against a lookup table, ClientTable and if valid, get the ClientId value from that ClientTable, so that I can populate the ClientID field in Table1.
I've got a mental block and I cannot see how I can do that !
Any ideas most gratefully appreciated.
Thanks

I have a table "Ratings" in which I store rating categories like the following:
FROM TO Rating
1 10 1
11 20 2
21 30 3
In another table "Results" I have the actual results like:
Employee ID Results Rating
120 6 ?
130 18 ?
Now I would like calculate the rating in the results table in the rating column (where "?" in the above example)
How can I do that with an SQL update command - maybe using a Case statement - but I don't know how to do that by looking up values from another table...
I'm trying to do a table lookup in t-sql and runing into problems. I have two tables, City and County..

I have another lookup table question
so say i have an employee table, and a department table. all the department table will do is store the names of the different departments so how should this be set up using MSSQL
Employee
EmployeeId
FN
LN
DeptName (fk)
Department
DeptId (pk) unique
DeptName unique
*** Or could i do this to make the employee record more meaningful without needing a join. ***
Employee
EmployeeId
FN
LN
DeptName (fk)
Department
DeptId (pk) unique
DeptName unique
*** Or should i just do this and get rid of the Id Field***
Employee
EmployeeId
FN
LN
DeptName (fk)
Department
DeptName (pk) unique
thanks all
i have very very basic knowledge of SQL like the ability to add, delete, update, select records and the ability to drop/create tables but i want to know how to integrate a lookup table into a field (very much like MS Access users can do with ease).
here is my example;
i have two tables - Club and Player
Club:
Club_Id
ClubName
Abbr
Player:
Player_Id
Name
Club_Id
the idea is that a single club can have several players. in the players table, i want the Club_Id field to act as the drop down whereas if a player changes club at any time, i can just refer to that player and change his Club_Id by scrolling down a list of values in SQL Server Management Studio 2005.
how can this be achieved by any chance, help would be very much appreciated.
Hi there
I'm getting into trouble everytime I want to setup a dataflow containing 2 or more flows, where I want to make a lookup into 1 other table.
This fails, of some reason I do not know of.
ex.
Table 1 -> Lookup Currency Table -> Table2 with currency
Table 3 -> Lookup Currency Table -> Table 4 with currency
One of the lookup will fail.
How do you avoid this?

I imported an Excel file in the form of a table(11,000 rows) in SQL Server 2012 database called Sanbox, I am trying to link this table to MS-CRM leads table so that I can link all the street addresses from table in Sandbox DB to the respective tables in MS-CRM leads table (200,000 rows), my end goal is to link the owner names from MS-CRM table to Sandbox DB's table with the matching criteria of 'street address'
My simple query looks like this, but it returns 200,000 rows, but I only want 11,000 rows -
SELECT *
FROM Sandbox.dbo.Sheet1$ A
LEFT JOIN [IPlus_MSCRM].[dbo].[FilteredLead] B
ON A.[Street 1] = B.address1_line1
Say I want to lookup a value in another dataset, but there is a grouping that requires you to know what the values for each level is in order to get to the correct detail record. Can you still use the lookup function with more than one field to compare against? So for example
Department
\___SalesPerson
\___Measure
I want to be able to add a new row at the Measure level, but lookup each field from another dataset. In order to do that I will need the Department AND SalesPerson values to do the lookup, but I dont think the Lookup function will let us do that will.
Hi i have three tables
T1 is a table of data imported by DTS, it has staff numbers and location names
T2 is a table that contains system data about staff and has a column for the location id
T3 is a table for the location names and their ID's
i am trying to write the sql to update T2 with the new location IDs for staff that have moved location but am not getting what i need.
so far i have :
update
T2
set T2.LocationId =T3.LocationID
from T3
inner join T1
on T3.departmentname = T1.contact_location
the update runs but sets all rows to the same value. am now burried deep in the [I've stared at this too long and cant see the wood for the trees] stage :mad:
Thanks

I'm using SQL Server 2000. I have an EXTERNAL_FUNDING table and an EXTERNAL_FUNDING_TYPE table. The DDL for the tables is listed below. Each EXTERNAL_FUNDING record has a type field, which is a foreign key to a record in the EXTERNAL_FUNDING_TYPE table. However, I would like for the type to be allowed to be null. When displaying the data, if the type is null, I'd like to show blank text. Here is the query I'm trying to use:
SELECT EXTERNAL_FUNDING.id, date_requested as [Request Date],source as [Source/Sponsor],EXTERNAL_FUNDING_TYPE.type AS [Type],amount as [Amount], granted as [Granted]
FROM EXTERNAL_FUNDING,EXTERNAL_FUNDING_TYPE
WHERE (project_id = @project_id) AND
(EXTERNAL_FUNDING.type = EXTERNAL_FUNDING_TYPE.id)
ORDER BY date_requested ,source,type
But this query does not return the records with NULL for the type field. Can someone explain to me how I can also return the rows with a NULL type? Thanks!
Table DDL:
CREATE TABLE [dbo].[EXTERNAL_FUNDING] (
[id] [int] IDENTITY (1, 1) NOT NULL ,
[project_id] [int] NOT NULL ,
[date_requested] [datetime] NULL ,
[source] [nvarchar] (50) COLLATE SQL_Latin1_General_CP1_CI_AS NULL ,
[type] [int] NULL ,
[amount] [money] NULL ,
[granted] [bit] NULL ,
[date_granted] [datetime] NULL
) ON [PRIMARY]

What is the best way to setup relationships between one lookup tableand many other tables. The tables did not have any lookup tablerelationships which I am adding. One lookup table is used for same datain several different places.To use one lookup tables with several tables, I had to disable "CascadeUpdate" and only have "enforce relationships for updates and inserts"checked.Any pros/cons?Thanks in advance.P

Can anybody tell me when the index table is created? I have a Ole DB Command transformation that deletes rows from a table, and the pipeline continues on to a fuzzy lookup. The fuzzy lookup is returning matches to some of the rows which were delted in the aformentioned Ole DB Command. If the index table is created during pre-execute, this would make some sense to me since those rows which get deleted still exist before the pipeline reaches the Ole DB Command transformation which deletes those rows. If this is the case, is there a way to delay the index table creation? If this is not the case, has anybody else ran into anything like this...is there some solution? Thanks for any help.
Hi,
I'm trying to figure out how to setup a Constraint (Foreign Key?) from a lookup table.
For the following example, I want to constrain to constrain so that a Car.ParkingSpotNumber is unique for a given ParkingFacility.
Any thoughts?
Thanks!
Andy
Here's the scenario:
CAR table:
Id (PrimaryKey)
LicensePlateNumber
ParkingSpotNumber
PARKINGFACILITY__CAR__LOOKUP table:
Id (PrimaryKey)
CarId (Foreign Key to Car.Id)
ParkingFacilityId (Foreign Key to ParkingFacility)
PARKINGFACILITY table:
Id (PrimaryKey)
PARKINGLOT table:
Id (Foreign Key to ParkingFacility.Id) (PrimaryKey)

Id (Foreign Key to ParkingFacility.Id) (PrimaryKey)

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,
I have a common requirement (when I'm processing data rows from an input file) to perform some data manipulation in script then look up a value from a reference table and perform some further data manipulation depending on whether a matching value was found in the lookup table or not.
For example, say I'm processing Customer data rows and the first "word" (/token) of the FullName column might be a title or the title could be missing and it might be a forename or initial instead. I want to check the first word of this FullName column to see if it matches any valid title values in a ReferenceTitles lookup table. If I find a match I want to set my Title column to the value from the ReferenceTitles lookup table, otherwise I want to set it to, say, an empty string. Then I want to process the rest of the FullName column tokens differently depending on whether or not a match was found.
It seems very messy to start coding a script transformation and then
have to use a lookup transformation combined with a script
transformation on the error output followed by a union and a sort
and finally a further script transformation (especially as I would like to be able to use variables from the first script in the later processing)...
So what I'm wondering is: Is there an easy/clean way to perform a database lookup (using cached values) from a script so that I can achieve all the above from within a single script component?
Thanks in advance,
Lawrie
