Error importing Data into table 'with schema flexibility' option

Hi I am creating a table

CREATE column TABLE FLEXIBI ( X INT ) WITH SCHEMA FLEXIBILITY;

and trying to import data through a csv file into the table with the following query

"IMPORT FROM CSV FILE '/tmp/mri/TSLE4.csv' INTO "FLEXIBI" WITH RECORD DELIMITED BY '\n' FIELD DELIMITED BY ';' COLUMN LIST ("A","B") with SCHEMA FLEXIBILITY"

but I get the the following syntax error

Could not execute 'IMPORT FROM CSV FILE '/tmp/mri/TSLE4.csv' INTO "FLEXIBI" WITH RECORD DELIMITED BY '\n' FIELD ...' in 4 ms 519 µs . SAP DBTech JDBC: [257] (at 151): sql syntax error: incorrect syntax near "SCHEMA": line 5 col 9 (at pos 151)

I have tried a lot of things but this query just does not seem to work. Any help would be appreciated!
