BLOB and CLOB Data Types - How Data Preview Looks - Example

[muthuram_shanmugavel2]

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,

Muthu
