SSIS Excel Error: Unexpected error from external database driver () when importing data from excel

Recently I had copied a excel file for analysis from SFTP site to development server from my account and asked my team mate to analyze it, by loading it into table.

He logged in to the server and used a simple data flow task in SSIS with source as Excel to load the data. When he was connecting excel using excel connection manager, he had a weird error.

Unexpected error from external database driver ()

He was unsure of why he was getting the error when selecting the sheet names. Then when reported, we quickly got into the possible reason of security.

As I copied the file from SFTP to Development machine using my account, it had limited the access to other users. When he was trying to load, he was facing the error because it was a read-only file for him.

Soon I granted full permission to him on excel security and it worked for him.

There are various different solution on internet but initially none worked for us when we were trying to resolve. Hope this solution would help someone!!

BIG Data, Hadoop – Chapter 2 - Data Life Cycle

Data Life Cycle The data life cycle is pictorial defined as show below: As we see, in our current system, we capture/ Extract our data, then we store it and later we process for reporting and analytics. But in case of big data, the problem lies in storing and then processing it faster. Hence Hadoop takes this portion, where it stores the data in effective format (Hadoop distributed File System) and also process using its engine (Map Reduce Engine). Since Map Reduce engine or Hadoop engine need data on HDFS format to process, We have favorable tools available in market to do this operation. As an example, Scoop is a tool which converts RDBMS to HDFS. Likewise we have SAP BOD to convert sap system data to HDFS.

SSIS: The Value Was Too Large To Fit In The Output Column

I had a SSIS package where I was calling a stored procedure in OLEDB Source and it was returning a “The Value Was Too Large to Fit in the Output Column” error. Well, My Datatype in OLEDB source was matching with my OLEDB Destination table. However, when I googled, we got solutions like to increase the output of OLEDB Source using Advanced Editor option . I was not at all comfortable with their solution as my source, destination and my intermediate transformation all are having same length and data type and I don’t want to change. Then I found that I was missing SET NOCOUNT ON option was missing in Stored Procedure. Once I added it, my data flow task ran successfully.

How to move multiple files in ssis and also rename simultaneously

There are two ways to achieve this. 1) We can move the flat files and then rename it. 2) While moving files itself, automatic rename should be done. We will do the second type. The criteria is to rename the files while moving from source to destination. So for that, we need FILE SYSTEM TASK to be included. Secondly since we need to move many files, we will use FOR EACH LOOP CONTAINER. To fetch all the files, we can use FOR EACH LOOP task in SSIS. In collection tab, we can select FOREACH FILE enumerator option for fetching files and we can change enumerator configuration Folder option: Points to source where we need to fetch files. Files: will give us idea whether we need to fetch all the files (*.*) or if we give extension like *.txt, it is going to fetch only .txt files . Once I give Source name in FOR EACH LOOP container, It is going to fetch all the files corresponding to that path. Retrieve file name: This option is used to let the variables mentioned in VARIA
