    Description

      CS 12.1.0 6a2afb42ba86188ccda0972f9c2df363f34e10a0 (Debug) Build 10/06/2025

      		 
      12.1.0-dbg>CREATE TABLE t1(v VECTOR (16384) NOT NULL,VECTOR (v)) ENGINE=InnoDB;
      		 
      ERROR 1074 (42000): Column length too big for column 'v' (max = 65532); use BLOB or TEXT instead
      		 
       
      		 
      12.1.0-dbg>CREATE TABLE t1(v VECTOR (16383) NOT NULL,VECTOR (v)) ENGINE=InnoDB;
      		 
      Query OK, 0 rows affected (0.012 sec)

      Besides the error, please also check if there is a off-by-one error, i.e. 16k=16384.

      Also, https://mariadb.com/docs/server/reference/data-types/numeric-data-types/vector mentions 65532 as well.
