How can I do a lookup which doens't directly link two columns but uses another statement?
I tried in advanced with:
Code Snippetselect * from
(select * from [dbo].[Employees]) as refTable
where [refTable].[EM_ID] = ? and [refTable].[EM_From] <= ? and
([refTable].[EM_Until] > ? or [refTable].[EM_Until] IS NULL)
and adding 2 parameters.
Error 1 Validation error. Fill Planning: Lookup [2376]: An input column with the lineage ID 1760, referenced in the ParameterMap custom property with the parameter on position number 1, cannot be found in the input columns collection. Package.dtsx 0 0
So I guess that's not the way to go. Any other way to tackle this?
I have two fields in one of my database table. They are date fields, one for the start and the other for the end of the "problem solving". What I want to do is to show the concrete elapsed time between the two.
My first problem is that I'm not able to show hour AND minutes. I wrote this for instance: SELECT DATEDIFF(hour, fld_date_debut, fld_date_fin) As elapsed_time I tried HH:mm instead of hour, but it is not working.
My second problem is that I can have more than one start and end hour for the same "problem solving". In the database it's like:
start hour: 10:00 End hour: 11:00 Number of the problem: 1 start hour: 13:00 End hour: 16:00 Number of the problem: 1
So I would like to add these to my elapsed time. I want (11:00 - 10:00) + (16:00 - 13:00)...but how can i do this in my SQL query ?
I came to know one of the better option in Oracle SQL for TOP-N Analysis-To find the top 5 usage accounts, top 10 users, etc. Is there any such way in SQL server ?
Is there any ways of using JOINS ( using keyword INNER & OUTER ) ? Some of the scripts that is generated automatically in Microsoft access with Join condition is not even working in MSSQL server 6.5. Is it true ? Or is there any other way that I can use these scripts in SQL 6.5.
If possible, pls. help me with some sample scripts ?
Can someone put me on the right track?I have a .bak file from an MSSQL 7.0 database. I want to restore thedatabase in SQL 2000 or 2005, but the restore fails with the error:"An exception occurred while executing a Transact-SQL statement or batch.(Microsoft.SqlServer.Express.ConnectionInfo)"and"I/O error (bad page ID) detected during read at offset 0x000000001be000 infile 'C:Program FilesMicrosoft SQL ServerMSSQLDataCLI_JP.mdf'. (.NetSqlClient Data Provider)"So it doesn't look good. I don't really know the meaning of the error andall I have is the .bak file. Is there a way to somehow convert the file, orread it?--Alvin
I have a bunch of contacts that I've scored how well their names match to other contacts in the same business. I can programmatically figure out how to parse the results, but would like to know how to do this via SQL. My problem is for Business_fk 968976 I have 7 contacts. In the end I should have 4 contacts based on name match. For the business key listed Gerardo Lopez is in the ContactScore table twice for Contact keys 7355719 and 57028145. I then have two rows like so:
Each reference each other, and 2 is a good case, a more difficult case would have key 1 listed 10 times showing a ContactMatch_fk of 2 - 11, and then Contact_fk 2 listed 10 times with a ContactMatch_fk of 1, 3-11.I know 57028145 maps to 7355719 from the first row in the ContactScore table, so when Contact_fk of 7355719 comes up I should be able to skip it and not process that match. Hopefully that makes sense. Anyway here is the test data:
IF EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[dbo].[ContactScore]') AND type in (N'U')) DROP TABLE [dbo].[ContactScore]; GO CREATE TABLE [dbo].[ContactScore] ( [ContactScore_pk]INT NOT NULL, [Contact_fk]INT NOT NULL,
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'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.
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.
Actually this is in regard to SCD Type 2 Dimension, Scenario is like that I am moving Fact table from some old source and I have dimensionA description value in fact which I want to replace with appropriate id from Dimension Table and that Dimension table is SCD Type 2 based on StartDate and EndDate and Fact Table doesn't contains direct date value rather there is timeId in Fact so to update the value in Fact table I have to Join Time Dimension table and other Dimension Table to replace fact Description with proper Id.
I am doing a lookup that requires mapping 2 columns in the column mapping section. When I do this, I get the error "Row yielded no match during lookup" . The SQL that I captured in SQL profiler does find the record when I run it in Management Studio. I have already tried trimming everything to no avail.
Why is this happening?
I tried enabling memory restrictions but then I my package hangs and I get a SQLDUMPER_ERRORLOG.log file with the following logged:
I have a Conditional Split with 3 outputs. On the first output I have a lookup, when I execute the package I have 56 rows going through the Conditional Split, all rows are then going to the 2nd and 3rd output but the lookup on the first output generates an error "Row yielded no match during lookup".
I don't understand why the lookup is generating an error while there is no row going through it.
I am designing a ssis package,This is intends to mine text data(Data extracted from websites). Term lookup/Term extraction has been used as tools for mining. I have lookup terms defined with me for reference table,but the main problem lie in extracting the nearby text/number/charcters to these lookup terms during mining. For example : I found noun "Email" 200 (frequency score) times in my text,Now I want to extract nearby email address(this is also true for PhoneNumber,Address attributes also).so how can I achieve this with SSIS. If u have some idea/suggestion to carry out this challenge with or without Term Extraction/Term Lookup,plz do write here.
I want to lookup values from a database into another database both of which are in the same sql server 2000. One databases is called GamingCommissiondb the other is called LicensingActions I need some of the tables to communicate with each other, to look values from one another. Example I need the Termination table to look up values from the Revocations table. Would using LinkedServers suffice??
Hi, Can anybody provide me a Lookup UDF? I need to supply columnname,Tablename and condition dynamically and I need the scalar value in return. Any help will be greatly appreciated...
Hi, I am transferring the xml data from an xml file into sql server table using ssis. To avoid any duplicate import via this ssis package, I would like to first check if data exists in the sql server table for what is about to be imported. If so then delete the existing data and then import.
Question: How do I get the field value say ID field from the file and then take this id and delete these from the table in sql server first.
Is this to do with lookup or is there an easier way to do this please? thanks
I am trying to use lookup to see if a item esists in my table ( 3 key fields ). If the lookup fails I want to insert the records. If it succeeds I have put a recordcount to catch the items that are not required. I don't think that I understand the settings for failed rows. I have tried setting the Configure Error Output to redirect, but this does not seem to work. I have the below errors.
[SQL Server Destination [151]] Error: Unable to prepare the SSIS bulk insert for data insertion.
[DTS.Pipeline] Error: component "SQL Server Destination" (151) failed the pre-execute phase and returned error code 0xC0202071.
Can someone please advise me how to set up this component to work for my application
I am using SCD and Lookup for Incremantal ETL load. But it is very interesting that my 3000 recs is becoming 2500 when I put SCD and lookup. if I replace dummy multicast then it is 3000.
Before inserting records of a recordset I would like to check that each one of these records doesn't exist in the destination table 1. If the records exist, they should be redirect to other table 2. For this purpose I use a lookup task. The referende table is the destination table 1. The green line is linked to table 2 and the red line is linked to table 1. The first execution works properly and copies de records to table 1, but on the next executions the records are copied to table 1 instead of being copied to table 2.
say i have a customer.aspx that allows a user to enter in customer data. on customer.aspx, i have dropdownSalesRep which allows the user to associate a sales rep with the customerbut some customers come to directly, and not thru a sales rep, so I want the user to be able to specify "none" Is it best to have a dummy record in my SalesReps table called "none" with an ID of say "999", or is there some other better way to deal with this?
I really need to know if it is possible to look in a Transaction Log for a specific transaction, it is for audit purposes. In the affirmative case, could you teach me how to do it or at least point me in the right direction.
I have a DTS package that calls a LOOKUP objects in an activeX script, I did not create this package and I am trying to figure out what it does, How do I view the actual LOOKUP object? I know what the LOOKUP object name is but cannot seem to find where it is actually stored?
I am trying to understand how to create an SP that will do the following on a varchar field: Someone enters a [Policy No] and the result set returns the [Policy No] the user entered (if found), plus 10 [Policy No]'s above and 10 [Policy No]'s below the [Policy No] they were looking for.
I figure this has to be a common thing that others have encountered, of course maybe not on a varchar data type field, but still this must be possible. If anyone can shed some light on this SP-Lookup with either some code or a general direction to go towards - I would greatly appreciate it! Thank you, Black
I have two tables: (results) one with numeric results and one with names (importance_scale)
SELECT * FROM results
name i1 i2 i3 i4 i5 ---- ---- ---- ---- ---- john 2 1 2 2 2 anna 0 2 2 2 2 phil 2 2 2 2 2 dave 1 0 2 2 2
SELECT * FROM importance_scale
imp_value imp_name --------- ------------ 2 very important 1 important 0 not important
i1,i2 etc. value it is a imp_value from table 'importance_scale'
I would like to make report which will show all results in this format (in example only first record): name i1 i2 i3 i4 i5 etc. ----- --- --- --- --- --- john very important important very important very important very important etc.
I was thinking about using CASE I don't want use cursor. What is the best way?
Hi, this may be a basic question but i can't get my mind straight and need some advice.
I've read there's limitations on using the Lookup Task.
What i want to do is simply look if a Data exists on a table, if it does i want to update some columns (or delete the row and insert a new row), if it doesnt exists i want to inser a row.
That's all, easy as hell in sql and c#/.net
The thing is i dont know whats the best way of doing it in SSIS.
My limited ssis knowledge tells me Script Component should be able to do the work. That is, send it a variable holding the values i want to verify in the database and depending if it exists to the whats necesary.
So my question is, can i connect to the DB via Script and make my custom selects there?
If so how can i do it?
If not, what's the best way of doing that simple task?
I am using a fuzzy lookup to cleanse data from a sales line details table, during the import process. The sales order line details contains a filed called 'reference' and this is compared to a field called 'category' in another table. Using data viewers to check through the cleansing process, I notice that the fuzzy lookup doesn't seem to match i.e. tbl.salesline.reference = 'I3' -> tbl.sales.category ='I03' the above is OK, but the lookup also returns the following tbl.salesline.reference = 'I9' -> tbl.sales.category ='I01' The value I9 doesnt exist, and is miskeyed by user entry, and should have been 'I99'. I would have expected the fuzzy lookup to pickup the I99 value as at least two of the chrs are matching, but no, it picks the first 'I*' in the table. If I expand the fuzzy lookup to return more results, i.e. 5 per record, then it returns the first 5 results....I01, I02 I03 and so on. Is there a way of improving the fuzzy lookup itself?
So i am designing a new database that currently has several tables 'look up tables' that are used just to limit the values of columns in other tables.
my question is what is the best way to do this?
1. multiple tables - one for each set of values (ex: JobType, Position, PayGrade) 2. One large table that holds all the lookup values - has a 'Category' field to group them 3. put constraints on the columns of the tables that are 'looking up' and get rid of the lookup tables.
I am doing something really simple and it doesnt work, may be I am missing something, What I am trying to accomplish is to load a fact table using lookup transaformation, however my source data was different from the data in my dimension (or the datatype ) I had to use a data conversion task before my lookup , so the data flow is something like this source -> Data Conversion -> Lookup -> destination , I am getting an error at my lookup task where it says the "[Lookup [82]] Error: Row yielded no match during lookup". and then it just fails. I know for sure that there has to be matching data. donno what is it that I am missing.
Hi, In my Excel file one column containing values like this:
Gender Male Female, Empty(NULL)
In my Sqlserver the lookup table look like this: GenderID Desc 1 Male 2 Female
Now I am using Lookup transformation. If there is no match in Lookup table I want to put null for GenderId in the main table. How to do this? Using lookup can we do this?
I am totally new to SSIS. I need an example of how to use a Lookup transformation. Basd on that i need to lookup for some recs and delete records from transaction table. I have used the Execute SQL task for this and i am able to achive my requirement. But now i am using XML configurations for Connection Managers and for that very reason i dont want to hard code the catalog names(database names) inside my Execute SQL task.
Can any one suggest me how to do the same using a Lookup transformation or any other. Any suggestions will be greatly appreciated.
I am running an import into a SQL Server 7 database with an Excel source using SSIS. When attempting to do a lookup on a field from the Excel file to a table in the SQL Server 7 database I get an error...
"Statement could not be prepared"
There are no additional details returned in the error and this is consistently happening. When I copy the table to a SQL 2005 server and use it as the reference for the lookup I receive no errors.
Has anyone else experienced this issue? I believe this may be a bug...
