MDS 2014 : How to Create Custom Index on MDS attributes

Hi All

we need to Create index on some of the Matching attributes in our Customer Entity. It is not straight forward in MDS DB , so for that we need to do the fallowing steps

Step1 : Get the Entity ID and EntityTable metadata from mdmtblEntity  table in MDS DB
Step2 : Need to Get the attribute tablecolumn from mdm.tblAttribute table .

we can create a Dynamic query to create custome index when you know EntityName and attributes names.

Dyanmic query



USE MDS
GO
Declare @SQL Varchar(2000), @f int =0
Declare  @i int, @S Varchar(50)
Select @S=EntityTable , @i=ID From mdm.tblentity where name='Customer'

If Exists (Select Name From Sysindexes Where Name='IX_Customer_MatchAttributes_001')
Begin
Set @SQL ='Drop Index IX_Customer_MatchAttributes_001 on mdm.' +  @S
exec  (@SQL)
set @f=1
End
Set @SQL   ='CREATE NONCLUSTERED INDEX IX_Customer_MatchAttributes_001
ON [mdm].'
Set @SQL= @SQL + '['+  @S +'] ('
Select @SQL = @SQL + '['+ Tablecolumn +']' From mdm.tblAttribute  where Name in ('matchAddress') and Entity_ID=@i
Select @SQL = @SQL + ','+  '['+ Tablecolumn +']  )
Include ('  From mdm.tblAttribute  where Name in ('matchPostCode') and Entity_ID=@i
Select @SQL=@SQL + '['+  Tablecolumn +']' From mdm.tblAttribute  where name in ('matchNameFirst' ) and Entity_ID=@i
Select @SQL=@SQL + ',['+  Tablecolumn +'] ' From mdm.tblAttribute  where name in ('nameLast' ) and Entity_ID=@i
Select @SQL=@SQL + ',['+  Tablecolumn +'] ' From mdm.tblAttribute  where name in ('emailAddress' ) and Entity_ID=@i
Select @SQL=@SQL + ',['+  Tablecolumn +'] ' From mdm.tblAttribute  where name in ('matchPhoneHome' ) and Entity_ID=@i
Select @SQL=@SQL + ',['+  Tablecolumn +'] ' From mdm.tblAttribute  where name in ('matchPhoneMobile' ) and Entity_ID=@i
Select @SQL=@SQL + ',['+  Tablecolumn +'] ) ' From mdm.tblAttribute  where name in ('MemberNumber' ) and Entity_ID=@I
exec (  @SQL )
--select @SQL

if @f=0
Begin
If Exists (Select Name From Sysindexes Where Name='IX_Customer_MatchAttributes_001')
Print 'Sucessfully Created Index IX_Customer_MatchAttributes_001'
End

if @f=1
Begin
If Exists (Select Name From Sysindexes Where Name='IX_Customer_MatchAttributes_001')
Print 'Sucessfully Re-Created Index IX_Customer_MatchAttributes_001'
End

SSAS : A connection cannot be made to redirector. Ensure that 'SQL Browser' service is running. (Microsoft.AnalysisServices.AdomdClient). + Solution

Problem : have installed Analysis service on my server machine through remote login from my service account. I am able to open Analysis services from there. When I open SSMS from the same service account on my local machine, I am not able to connect to that Analysis service. It is giving me error by saying : "A connection cannot be made to redirector. Ensure that 'SQL Browser' service is running. (Microsoft.AnalysisServices.AdomdClient). A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connection host has failed to respond 10.245.192.111:2382(System)." Solution : Based on my research, the issue was caused by the Browser Service account was changed to the domain account. In your scenario, you can try to connect to the Analysis Service using <Servername>:2383 instead of instance name. Or you can change the Browser Service account to "Local System"....

SSIS Error : Unable to infer the XSD from the XML file. The XML contains multiple namespaces

Image
Problem : When we have Multiple Namespaces in the Xml Source which we need to load the Data from   as we shown below Then we will face a issue in generating XSD for that XML Error : Unable to infer the XSD from the XML file. The XML contains multiple namespaces. (Microsoft Visual Studio) Solution : First we need to avoid multiple namespaces to transform your source file to a format that doesn’t refer to the namespaces. SSIS has an XML task that can do the transformation. 1) Add the XML task to an SSIS   Control Flow and edit it. 2) Change the OperationType property value to XSLT, the SourceType to File connection and the Source to your source file that has the problem. 3) Set the SaveOperationResult property to True and expand the OperationResult branch. Set DestinationType to File Connection and the Destination to a new XML file ( ModifiedInput.XML). 4) Add the below script to a new file and save it with an xslt file extension (Input.XSL...

SSRS : [Teradata Database] 3939 There is a mismatch between the number of parameters specified and the number of parameters required.

Error : [Teradata Database] 3939   There is a mismatch between the number of parameters specified and the number of parameters required. When we get this Error : when we are creating SSRS reports on Teradata database and in which when we are using parameters in the dataset in wrong style\format. Just for Info :  to connect Terdata we need to have  .Net Data provider for Terdata  when we installed this on our machine  Then we are able to see Teradata data source type in SSRS. How to Solve this issue :  This error will come if we are not using correct syntax to create parameterized data set .  The correct way is we need to ?  for parameter The report parameters can be named or unnamed. Teradata only supports unnamed parameters. An unnamed parameter is denoted by a ‘?’, and is merely a placeholder for data that is going to be entered at report processing time. For example, the following is a dataset with a single-value ...
