Using Collate on Join conditions

I am joining 2 tables T1 and T2 based on a condition T1.A = T2.BT1.A have values like 'wNFq' and T2.B have values like 'WNFQ', 'wnfQ', 'WnFq', 'wNFq'For a regular join a particular row of 'wNFq' from T1 gets joined with all values: 'WNFQ', 'wnfQ','WnFq' and 'wNFq' of T2My intention is to join only 'wNFq' from T1 to 'wNFq'.I achieved the same using custom SQL insert and using the below  COLLATE function to join based on case sensitive sequencing using:T1.A COLLATE Latin1_General_CS_AS_KS_WS = T2.B COLLATE Latin_1_General_CS_AS_KS_WSWandering if there is a different way to achieve this avoiding custom SQL.Appreciate any help on the same.

Filtering on the Look up fields

Created a conditional lookup based on following : T1 joined to T2 where T1.A = T2.B Looked up T2.C based on the above join condition and stored the value in T1.D Now I need to filter the resultant data set which is on T1 based on certain values of T1.D Unable to put that filter in the Table Data Selection Rule. Even I tried to copy T1.D(look up filed) to T1.E (a separate filed created just to hold the value of T1.D) and filter on T1.E, even that did not work. Appreciate help on the same.

Many to many Relations and conditional joins

Hi,I am trying to build a transformation process in TX based on the following SQL code.------------------------------------------SELECT distinct[BusinessEntityID],B.MonthKey,[StartDate],[EndDate],[DepartmentName]FROM [TX_DSA].[dbo].[EmployeeDepartmentHistory] Ajoin dbo.Calendar B ON B.Date >= A.StartDatewhere b.DateValue >= a.StartDate AND (a.EndDate is null or a.EndDate <= b.DateValue)----------------------------------------------------I want intentionally to expand the grain of table A. I tried different Joins and conditional lookups but I just can't reproduce the output.How would you solve this?Thanks in advancegrJose

database diagram: visualize your data model

Hi, i've setup a MDW layer with proper relations between tables. At this point I wanted to create a relation diagriam to visualise to my client the relation between his entities. my tool of choice was SQL Management Studio. Only then i've realised that TimeXtender only create DW_Id as physical primary key and the relations between tables are managed internally Is there a way in TimeXtender to visualize the relations between the tables? I've already put my vote here

How to create a transformation that is different for each mapping going to the same table

Example scenario:Table DimProject has 2 mappings, each from a different source:Mapping 1 = SourceA.ProjectMapping 2 = SourceB.ProjectNow both systems will have the same project number with different meanings.My question is how do I make a transformation that returns 'A' + [project number] in mapping 1 and 'B' + [project number] in mapping 2.The solution needs be rely on explicitly meaningful conditions, no implicit conditions that drive people crazy trying to decipher what they are for somewhere in the future.Any ideas?

Deadlock on sys.tables

I have been running into a problem where my execution package keeps failing due to a deadlock between an index rebuild and a select statement on sys.tables. TimeXtender is running both process' and one eventually gets killed and fails the entire job. in subsequent executions it has always failed on an index rebuild, but not the same index. Has anyone run into this issue or have any solutions? here's the query.SELECTSCHEMA_NAME(tbl.schema_id) AS [Schema],tbl.name AS [Name],tbl.object_id AS [ID],CAST(case    when tbl.is_ms_shipped = 1 then 1    when (        select            major_id        from            sys.extended_properties        where            major_id = tbl.object_id and            minor_id = 0 and            class = 1 and            name = N'microsoft_database_tools_support')        is not null then 1    else 0end                      AS bit) AS [IsSystemObject]FROMsys.tables AS tblORDER BY[Schema] ASC,[Name] ASC

Primary key violation - which record is then valid ?

When you set up primary key behaviour to 'error' you elegantly force all valid data to be unique combinations of your selected primary keys. But, how do you control what individual dataset is regarded as valid and what is discarded as error ? Is there a way to let the primary key violation error handling know, which record you consider the valid one ?  (e.g. based on min/max values in non-primary key data fields)

Table truncation options

Hi guys,Can someone elaborate the different options of table truncation? I can't really find it in the help or e-learning. We have set up an incremental load on a large table in the ODX, initially in simple mode. We found that the data after deployment & execution exists in the valid table and in the raw table, occupying twice the available storage of the original table size. We then disabled simple mode and checked the truncate raw table before transfer. I now still see some records (not all of them) in the raw table. I guess I'll have to check "Empty raw table after data cleansing" to completely empty the raw table after reloading, but I can't really grasp the difference between these options.

Converting int/char to date

Hello, I have a problem that i am struggling with. I have a table that contains field called [Period] and it stores month dates in following int format: 2201, 2202, 2203 which i need to translate to 2022-01-01, 2022-02-01, 2022-03-01 etc. to date format (always 1st day of month) The problem is i can convert the source format to date format in the view, but when i am trying to generate a table from that view, i always get an error that [Period] cannot be converted to date format. I have different options and nothing has worked as timextender always fails to convert to date format. Everything that failed on timextender, worked perfectly on MSSQL so i am not sure what is wrong. Thanks for your help
