SSIS ForEach Loop Error : ForEach Variable Mapping number n to variable "%s" cannot be applied.

When we are trying to select  different columns which includes bigint column also and insert that result into SSIS Object datatype variable  Using Execute SQL task . In the next Step when we are using that same Object varible  in ForEachLoop then we are facing this Error .

Error: The type of the value being assigned to variable "User::MaxEpoch" differs from the current variable type. Variables may not change type during execution. Variable types are strict, except for variables of type Object.
Why this error is coming :  In ForEachloop the Bigint value from the Object Variable is mapped to Int64 datatype variable in SSIS . Here the problem is occuring that convertion is not possible in ForEach Loop when dealing with Object variable as enumerator . When we are trying to insert BigInt column value directly into Int64 variable using ExcuteSQL task is working fine .The problem is with ForEachloop only .

Work around :  we are converting that BigInt Column into Varchar before inserting into the Object variable and later In For each loop we are Mapping that column to String datatype variable .

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.XSLT) <
