Smart SAP Assistant

• What is the cause and solution for SAP error message DT758 - ROW store not allowed: Table & contains column(s) of type GEOM_EWKB ?

  The SAP error message DT758 indicates that you are trying to create or modify a table that contains columns of type GEOM_EWKB (which is a geometry type used for storing spatial data) in a row store database. However, row store tables do not support this type of column.
  Cause:
  The primary cause of this error is that the database table you are trying to create or modify is defined as a row store table, but it includes one or more columns of type GEOM_EWKB. Row store tables in SAP HANA do not support spatial data types, which is why you are encountering this error.
  Solution:
  To resolve this error, you have a couple of options:
  
  
  Change the Table Type:
  
  If you need to store spatial data, you should create the table as a column store table instead of a row store table. Column store tables in SAP HANA support spatial data types, including GEOM_EWKB.
  You can specify the table type when creating the table using the SQL command:
  CREATE COLUMN TABLE your_table_name (
      your_column_name GEOM_EWKB,
      ...
  );
  
  
  
  
  Remove Spatial Columns:
  
  If the spatial data is not necessary for your application, you can remove the columns of type GEOM_EWKB from the table definition. This will allow you to create or modify the table as a row store table.
  
  
  
  Related Information:
  
  SAP HANA Documentation: Refer to the official SAP HANA documentation for more details on data types and table types. This will provide you with comprehensive information on how to work with spatial data and the differences between row store and column store tables.
  Spatial Data Handling: If you are working with spatial data, consider using the appropriate functions and features provided by SAP HANA for handling spatial data types effectively.
  Performance Considerations: Understand the performance implications of using row store vs. column store tables, especially when dealing with large datasets or specific types of queries.
  
  By following the above solutions, you should be able to resolve the DT758 error and successfully create or modify your table as needed.
