 Description   

We'll introduce a new token type "create_field" in sql_yacc.yy:

%union {
 
...
 
  Create_field *create_field;
 
...
 
}

and change data type of the rules "field_spec" from and "column_def from NONE to create_field.

The rule "field_spec" will return the value created by this code:

field_spec:
 
          field_ident
 
          {
 
            LEX *lex=Lex;
 
            Create_field *f= new Create_field();
 
         ...

The rule "column_def" will further return the value created by its "field_spec" part.
