SSIS - Excel data source not taking more characters than 255

-
Problem:

I have developed SSIS package that import multiple excel files into SQL. Now issue is "Excel data source" check first few rows for determine datatype and it took text data type with length 255 for my remarks column.
But in some files remarks is longer than 255 chars.
I checked some blogs they saying intentional put long text in first row for remarks then SSIS will determine datatype as Unicode text stream. That solved my problem but when other file comes to import datatype again changed to 255 chars and getting truncation error.
Please advise how to fix this issue.

Solution:

Inside the Data Flow Task, right click on the Excel Source component, got to Advanced Editor >> Input and Output Properties Tab, and change the column length manually in the External Columns and Output Columns as shown in the screenshot below.

Don’t install Hadoop on Windows!

A few years ago, I was hearing from my colleagues “don’t ever think about installing Hadoop on Windows operating system!” . I was not convinced of this saying because I am a big fan of Microsoft products, especially Windows. In the past three years, I worked on three projects where I was asked to build a Hadoop cluster on Ubuntu. The first time, it was a single-node Hadoop installation with a single Apache Spark worker. The other projects were about building a Big Data ecosystem for radiation data engineering , where the multi-node Hadoop cluster is deployed. Besides Hadoop, we installed and configured Apache Kafka, Spark, Hive, Pig, and Flume installations (I have published some installation guides previously, you can check the links at the end of this article). It was hard to become familiar with those technologies for the first time since they don’t have much documentation online. Each time I had to install Hadoop, I was thinking that why always Hadoop is installed on Linu

SSIS - script component DateTime Formats Implicit Conversion

General Info These are the default formats of datetimes datatypes (when converting from string) DT_DBDATE yyyy-mm-dd DT_FILETIME yyyy-mm-dd hh:mm:ss:fff DT_DBTIME hh:mm:ss DT_DBTIME2 hh:mm:ss[.fffffff] DT_DBTIMESTAMP yyyy-mm-dd hh:mm:ss[.fff] DT_DBTIMESTAMP2 yyyy-mm-dd hh:mm:ss[.fffffff] DT_DBTIMESTAMPOFFSET yyyy-mm-dd hh:mm:ss[.fffffff] [{+|-} hh:mm] Note: DT_DATE and DT_DBTIMESTAMP has the same SET method And i think that converting string to date is depending also on your current culture info More detailed information are found here https://msdn.microsoft.com/en-us/library/ms141036.aspx http://www.bidn.com/blogs/DevinKnight/ssis/1387/ssis-to-sql-server-data-type-translations Experiments : I didn't find any related article on this issue so i made the following experiments: SSIS Implicit datetime Conversion i created a SSIS package with a Dataflowtask. in this dataflowtask i created a Script Component (as a Source) and a Flat File Destin
