Re: Change the length of a Column

Hi Sreelatha ,

Please go through the HANA Documentation before Posting the Question.

Here are some excerpts from HANA Documentation:

• For column table, only increasing the size of a column data type is allowed to prevent data loss. For example, changing from nvarchar(20) to nvarchar(10) or from integer to tinyint will raise an error.
• For row table, only increasing the size of VARCHAR and NVARCHAR type column is allowed. Other data type changes are not allowed.

You can visit the link:

ALTER TABLE - SAP HANA SQL and System Views Reference - SAP Library

So you can do the following:

You can drop and create it. Take the backup of table to reload it.

Hope this helps
