BLOB and CLOB Data Types – How Data Preview Looks – Example
I am going to show example –> How data preview looks for BLOB and CLOB data types.
I have created table with columns having BLOB and CLOB data types.
I have inserted the unstructured data to both columns (same data). Then I have checked the data preview of the table.
Text I Inserted (Starts With): Strong demand ..
Column having CLOB Data Type: It shows the same value as I inserted. (String Format)
Column Having BLOB Data Type: It shows the value in Hexadecimal Format – (Hexadecimal Value calculated based on Binary digits)
String – Strong demand, Binary value and Hexadecimal value are listed below as per ASCII standard.
As per this table, Strong demand in Hexadecimal form is –> 5374726F6E672064656D616E64
We will check data preview in HANA table now.
Hexadecimal content is shown for BLOB column and string content is shown for CLOB data types for the same texts.
I hope that you would have got the understanding that How BLOB and CLOB data types storage behaves.
Thanks & Regards,

Good effor Muthu to start with. It is simple to read and understand a HANA capability or concept in less than 2 minutes.waiting for more simple articles from you like this.
A suggestion - you can even rename the topic something like this.
HANA Concepts Example 1 - CLOB and BLOB how it looks.
HANA Concepts Example 2 - XXXXX
Thank you, Please can you shed some light on NCLOB as well? thanks
