When Clause with FIELDS TERMINATED BY and TRAILING NULLCOLS option?

Question

Dear all
If i have the following datafields:
E;15;
D;14;16;
E;18;
to load into table tab1 (Type_ligne VARCHAR2(1),
                                 Nombre1 NUMBER(2),
                                 Nombre2 NUMBER(2))
Is it possible to have the following control file :
LOAD DATA
TRUNCATE
INTO TABLE Tab1
when (1) ='E'
FIELDS TERMINATED BY ';' TRAILING NULLCOLS
(Type_Ligne CHAR,
Nombre1 INTEGER EXTERNAL)
INTO TABLE Tab1
when (1) ='D'
FIELDS TERMINATED BY ';' TRAILING NULLCOLS
(Type_Ligne  CHAR,
Nombre1 INTEGER EXTERNAL,
Nombre2 INTEGER EXTERNAL)
If no! please show me the correct syntax.

Answer 1

Yes, you can, but for each WHEN clause after the first one, you have to specify the starting position for the first field, as shown in bold below.
LOAD DATA
TRUNCATE
INTO TABLE Tab1
when (1) ='E'
FIELDS TERMINATED BY ';' TRAILING NULLCOLS
(Type_Ligne CHAR,
Nombre1 INTEGER EXTERNAL)
INTO TABLE Tab1
when (1) ='D'
FIELDS TERMINATED BY ';' TRAILING NULLCOLS
(Type_Ligne  POSITION(1) CHAR,
Nombre1 INTEGER EXTERNAL,
Nombre2 INTEGER EXTERNAL)
