Select statement inside function with into keyword

Question

Hi Everyone,
i have a function which contains a select statement
create or replace
function fun_1(Table_Name1 in varchar2)
RETURN VARCHAR2
is
VAR_GEN_TYPE NUMBER(10);
TA_U varchar2(256);
VAR_DATA_FLAG varchar2(1);
begin
select T.FLAG into VAR_GEN_TYPE ,T.DATA_UID_GEN_TYPE into VAR_DATA_FLAG  from T_DYNAMIC_TABLE T  where T.TABLE_NAME=TABLE_NAME1;
end
whene ever i am executing this function giving error message: From Keyword  Not Found
when i change select statement to
select T.FLAG ,T.DATA_UID_GEN_TYPE into VAR_DATA_FLAG, VAR_GEN_TYPE from T_DYNAMIC_TABLE T where T.TABLE_NAME=TABLE_NAME1;
then it is working
why first statements will not work ?
i.e.,
select T.FLAG into VAR_GEN_TYPE ,T.DATA_UID_GEN_TYPE into VAR_DATA_FLAG from T_DYNAMIC_TABLE T where T.TABLE_NAME=TABLE_NAME1;
why in select statement we cannot use into keyword more than one time ?

Answer 1

select T.FLAG into VAR_GEN_TYPE ,T.DATA_UID_GEN_TYPE into VAR_DATA_FLAG, from T_DYNAMIC_TABLE T where T.TABLE_NAME=TABLE_NAME1;
into should be only once..
the syntax should be
select <column list>
into
<variable list>
from <table name> where <condition>
--This query shuold return only one row.
column list count and variable list count should match
there should be no comma after last variable.andbefore from.
