    Description

      Since MariaDB Server 10.5 data type JSON is not returned as MYSQL_TYPE_JSON anymore, but as MYSQL_TYPE_BLOB with extended field attributes, which results in wrong data type:

      import mariadb
      		 
       
      		 
      conn=mariadb.connect(db="test")
      		 
      cursor=conn.cursor()
      		 
      cursor.execute("create temporary table t1(a json)")
      		 
      cursor.execute("insert into t1 values ('{}')")
      		 
      cursor.execute("select * from t1");
      		 
      fieldinfo= mariadb.fieldinfo()
      		 
      info= cursor.description
      		 
      print(fieldinfo.type(info[0]))
      		 
      del cursor
      		 
      del connection

      Output:

      BLOB
