This error is often encountered when trying to create or modify a table without specifying whether it should use a row store or a column store.
  Cause:
  
  Missing Storage Specification: The error arises when a table is being created or altered without explicitly defining whether it should be a row store or a column store.
  Default Settings: If the system's default settings do not specify a storage type, the system may not know how to proceed with the operation.
  SQL Syntax: The SQL command used may be missing the necessary parameters to define the storage type.
  
  Solution:
  To resolve the DT743 error, you need to specify the storage type when creating or altering a table. Here’s how you can do that:

  CREATE TABLE my_table (
      id INT,
      name NVARCHAR(100)
  ) WITH (DATA_STORE = 'COLUMN');
  
  Alternatively, if you want to create a row store table, you can use:
  CREATE TABLE my_table (
      id INT,
      name NVARCHAR(100)
  ) WITH (DATA_STORE = 'ROW');
  
  
  
  
  Check Default Settings: If you want to set a default storage type for your tables, you can check the system settings in the SAP HANA Studio or through SQL commands.
