To avoid synthetic keys you have to avoid the use of same field names in more than to tables

Hi,

You can try alias function in script when two or more tables are having same name.

like this,

Employee Names         as        EMPName

Employee Names        as        EMPnames

Hi,

You can resolve synthetic key by renaming fields which having same name in both table ,

It will create when fields from data tables are common more than one field

Tbl:

A,

B

from source;

Tbl2:

A,

B

from source;

It will create synthetic table with A & B fields for removing synthetic key you need to follow below approach,

Tbl:

A,

B

from source;

Tbl2:

A,

B as B_new

from source;

HidePrefix :


All field names beginning with this text string will be hidden in the same manner as the system fields. A user-defined variable.

Example:

set HidePrefix='_' ;

If this statement is used, the field names beginning with an underscore will not be shown in the field name lists when the system fields are hidden.

Example:

set HidePrefix='_' ;

LOAD

ID AS _Key

'

'

FROM DataSource;

Now _Key is not visible in the Fields listbox, if you want to see this column then you need to select Show System Fields option.
