Text file to oracle ???

Question

Hi,
i have one text file which contains
two columns code and datavalue.
based on code for eg if 01
then data should insert into EDI01 tables and datavalue respectively.
and so on may be upto code 99
Is there any sql statement with which
i can do in very short instead 100 if and else!
i mean like this
v_code is 00 to 99
v_datavalues corresponding to code from the text file
insert into EDI||v_code values(v_code,v_datavalue)

You can, so, send the client machine file to the Application Server with the Webutil webutil_file_transfer package, then load each record with the TEXT_IO package.
here is a function that allow to take tokens from a delimited string, to get every single element from one line:
CREATE OR REPLACE FUNCTION Split ( PC$Chaine IN VARCHAR2, PN$Pos IN PLS_INTEGER, PC$Sep IN VARCHAR2 DEFAULT ',' )
RETURN VARCHAR2
IS
LC$Chaine VARCHAR2(32767) := PC$Sep || PC$Chaine ;
LI$I  PLS_INTEGER ;
LI$I2 PLS_INTEGER ;
BEGIN
LI$I := INSTR( LC$Chaine, PC$Sep, 1, PN$Pos ) ;
IF LI$I > 0 THEN
    LI$I2 := INSTR( LC$Chaine, PC$Sep, 1, PN$Pos + 1) ;
     IF LI$I2 = 0 THEN LI$I2 := LENGTH( LC$Chaine ) + 1 ; END IF ;
     RETURN( SUBSTR( LC$Chaine, LI$I+1, LI$I2 - LI$I-1 ) ) ;
ELSE
    RETURN NULL ;
END IF ;
END;you can get the first and second element:
LC$Line := TEXT_IO.Get_Line( file ) ;
id    := Split( LC$Line, 1 );
label := Split( LC$Line, 2 );
Insert Into ...
Values (id, label);
