Lookup Table, Extracting Values

Sep 21, 2007

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?

Lookup / Merge Join / Script - Howto Look Up Values By Comparing To A Range Of Values?

Jun 4, 2007

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...

Performance Expectations For Fuzzy Lookup Against 25mill Row Lookup Table

Oct 31, 2007

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?

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

My excel file has some formulas to get the data from other worksheets. I added a Data Viewer and all I see is null values in every cell.

Extracting Data From Columns That Contain Multiple Values Spearated By A Comma

Nov 11, 2004

Hi all,

If I have a column in one table (contracts) that contains a set of values (codes that identify the fields contract code) like as follows...


Code:


Contracts table
--------------------------------
Concode - description
--------------------------------
KIDD - Kidderminster General
UNIV - University Hospitals



and then another table (controls) which has a column called contracts where the data within the 'Contracts' field is set out like the following (yes that is right, each of the data in this column are the Foreign Keys which are separated by '/' in which I need to query against the contracts table ) ...


Code:


controls table
--------------------------
Code - Contracts
--------------------------
BA - KIDD /UNIV /NWPCT



With the those tables and the columns like they are, how can I get my query to display the following information...


PHP Code:




---------------------------------------------------
Con(Controls table) - Description(contracts table)
---------------------------------------------------
             BA          - Kidderminster General
             BA          - University Hospitals
--------------------------------------------------- 






I'm guessing my first job is to somehow extract those Foreign Keys from the 'Contracts' column in the 'Control' table

Extracting Parameter Values From A Custom Data Processing Extension

Jun 23, 2006

I've created a custom Data Processing Extension and I've implemented the IDBCommandAnalysis interface so that my reports can enter parameters and pass them to my Data Processing Extension.

My question is, how do I extract the value from the Parameters coming from the report? Where do the parameters get passed off from the report? I can query the Parameters collection and my report gets prompted in Preview mode to enter something for the parameter but I can't find the spot where it gets passed for processing.

Inner Join To Lookup Values Twice?

Jul 20, 2005

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

Ignoring NULL Values In LOOKUP Transformation.

Jun 28, 2006

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

Conditional Lookup &&amp; Returning Undefined Values On Error

May 30, 2007

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

Reporting Services :: SSRS 2008 - Trying To Sum Lookup Values

Feb 13, 2012

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.

Extracting Information Outside A Table

Feb 22, 2008

Hi,

I have two tables - a stock table and a transaction table. The stock table is called stock and the transaction table is called trans. The table make a point of sale database. Both table have a joining field called prod_no.

I want to extract the stock line by querying stock.prod_no that are not present in the trans table for a period of time specified.

Basically, I want to find dead stock lines that have not been sold and, therefore, are not in the transaction table but that have a stock figure. I have to enter in a start and end date paramater using the ddate field in the trans table. I have looked at left, right and outer joins but with no luck and don't even know if this is the correct query type to use.

any help would be much appreciated,

Extracting Data From A Table For Archiving Purposes

Sep 22, 1999

Hello,

I have been placed in the position of administering our SQL server 6.5 (Microsoft). Being new to SQL and having some knowledge of databases (used to use Foxpro 2.6 for...DOS!) I am faced with an ever increasing table of incoming call information from our Ascend MAX RAS equipment. This table increases by 900,000 records a month. The previous administrator (no longer available) was using a Visual Foxpro 5 application to archive and remove the data older than 60 days. Unfortunately he left and took with him Visual Fox and all of his project files.

My question is this: Is there an easy way to archive then remove the data older than 60 days from the table? I would like to archive it to a tape drive. We need to maintain this archive for the purposes of searching back through customer calls for IP addresses on certain dates and times. We are an ISP, and occasionally need to give this information to law enforcement agencies. So we cannot just delete it.

Sorry this is so long...

Thanks,

Extracting And Joining Header From Denormalized Table

Dec 1, 2005

Hello,I am currently working on a monthly load process with a datamart. Ioriginally designed the tables in a normalized fashion with the ideathat I would denormalize as needed once I got an idea of what theperformance was like. There were some performance problems, so thedecision was made to denormalize. Now the users are happy with thequery performance, but loading the tables is much more difficult.Specifically...There were two main tables, a header table and a line item table. Thesehave been combined into one table. For my loads I still receive them asseparate files though. The problem is that I might receive a line itemfor a header that began two months ago. When this happens I don't get aheader record in the current month's file - I just get the record inthe line items file. So now I have to join the header and line itemtables in my staging database to get the denormalized rows, but I alsomay have to get header information from my main denormalized table(~150 million rows). For simplicity I will only include the primarykeys and one other column to represent the rest of the row below. Thetables are actually very wide.Staging database:CREATE TABLE dbo.Claims (CLM_ID BIGINT NOT NULL,CLM_DATA VARCHAR(100) NULL )CREATE TABLE dbo.Claim_Lines (CLM_ID BIGINT NOT NULL,LN_NO SMALLINT NOT NULL,CLM_LN_DATA VARCHAR(100) NULL )Target database:CREATE TABLE dbo.Target (CLM_ID BIGINT NOT NULL,LN_NO SMALLINT NOT NULL,CLM_DATA VARCHAR(100) NULL,CLM_LN_DATA VARCHAR(100) NULL )I can either pull back all of the necessary header rows from the targettable to the claims table and then do one insert using a join betweenclaims and claim lines into the target table OR I can do one insertwith a join between claims and claim lines and then a second insertwith a join between claim lines and target for those lines that weren'talready added.Some things that I've tried:INSERT INTO Staging.dbo.Claims (CLM_ID, CLM_DATA)SELECT DISTINCT T.CLM_ID, T.CLM_DATAFROM Staging.dbo.Claim_Lines CLLEFT OUTER JOIN Staging.dbo.Claims C ON C.CLM_ID = CL.CLM_IDINNER JOIN Target.dbo.Target T ON T.CLM_ID = CL.CLM_IDWHERE C.CLM_ID IS NULLINSERT INTO Staging.dbo.Claims (CLM_ID, CLM_DATA)SELECT T.CLM_ID, T.CLM_DATAFROM Staging.dbo.Claim_Lines CLLEFT OUTER JOIN Staging.dbo.Claims C ON C.CLM_ID = CL.CLM_IDINNER JOIN Target.dbo.Target T ON T.CLM_ID = CL.CLM_IDWHERE C.CLM_ID IS NULLGROUP BY T.CLM_ID, T.CLM_DATAINSERT INTO Staging.dbo.Claims (CLM_ID, CLM_DATA)SELECT DISTINCT T.CLM_ID, T.CLM_DATAFROM Target.dbo.Target TINNER JOIN (SELECT CL.CLM_IDFROM Staging.dbo.Claim_Lines CLLEFT OUTER JOIN Staging.dbo.Claims C ON C.CLM_ID =CL.CLM_IDWHERE C.CLM_ID IS NULL) SQ ON SQ.CLM_ID = T.CLM_IDI've also used EXISTS and IN in various queries. No matter which methodI use, the query plans tend to want to do a clustered index scan on thetarget table (actually a partitioned view partitioned by year). Thenumber of headers that were in the target but not the header file thismonth was about 42K out of 1M.So.... any other ideas on how I can set up a query to get the distinctheaders from the denormalized table? Right now I'm considering usingworktables if I can't figure anything else out, but I don't know ifthat will really help me much either.I'm not looking for a definitive answer here, just some ideas that Ican try.Thanks,-Tom.

Extracting XML From An SLQ Table Column Then Getting Delimted Vales From Within That XML...

Dec 6, 2007

Hi all.

This is my first SSIS project it's also an utter mare.

I'm a C# developer with reasonable SQL knowledge but I haven't used SSIS projects in BIS before.

What we have (for some insane reason) is an SQL table like so:

Column A |Column B |Column X |

Where Column X contains XML like this:
<Column C></Column C><Column D></Column D><Column ArrgWTF></Column ArrgWTF>

Where <Column ArrgWTF> contains two '-' delimited values.

What I need is some guidence (or just being told if its possible or not) to take this data and arange it like so (see bellow) in a new SQL table:

Column A |Column B |Column C | Column D |Column ArrgWTF1 |Column ArrgWTF2 |

Where A&D are from the original SQL table, C & D are pulled from the XML and ArrgWTF1 & 2 are sourced from the '-' delimited vales within the XML.

Many, many, thanks in advance.

Check Constraint - Compare Sum Of Two Values In One Table Against Values Located In Another Table

Jul 26, 2014

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.

Power Pivot :: DAX Formula For Extracting A Column Value From Table Based On Certain Conditions

Jul 20, 2015

I'm trying extract a column from the table based on certain Conditions: This is for PowerPivot.

Here is the scenario:

I have a table "tb1" with (project_id, month_end_date, monthly_proj_cost ) and table "tb2" with (project_id, key_member_type, key_member, start_dt_active, end_dt_active).

I would like to extract  Key_member where key_member_type="PM" and active as of tb1(month_end_date).

Is this possible using DAX ?
