ROWID in *.dbf Files

You are viewing an old version of this question. View the current version here.

Is there a way to get the recno() / ROWID as field from the *dbf File?


Yes indeed. Just use a CONNECT special column, for instance:

create table t1 ( id int(6) not null, msg char(10), recno int(4) not null default 0 special=rowid ) engine=connect table_type=DBF file_name='afile.dbf';

insert into t1(id,msg) values(2,'two'),(3,'three'),(5,'five');

select * from t1;

The table will be displayed like this:


This is true for all file based CONNECT tables. However, for DBF tables:

Note 1: The current CONNECT version has a bug that causes an error being raised when inserting in a new void table (because special columns are wrongly kept when writing the header) This will be fixed in next versions. Meanwhile, you can insert in a new void table with a table defined without the special column and later add the special column with an ALTER TABLE statement.

Note 2: If instead of a ROWID special column you use a ROWNUM special column, it will give the record number including the "soft" deleted lines.
