Now, i want to insert into stck and stol table based on temp table records. constraints to insert into stck and stol tables are as below
In temp table first column is called stock. This stock has to compare with stck table stock_code. If it is not present in stck table, then it has to insert into stck table with stock_id and stock_description. Here, I need to generate stock_id my self in the code.
In temp table, column 3 to column 22, i have alias. Each column has to check with stol table stock_code column. For instance, column3 check with stock_code column. Then column4 check with stock_code. If stock_code is not present in stol table, then i have to insert into stol table.
I need to generate stock,id in the code. How do i perform this insertion?

Answer 1

It can be done using SQL (no loops required)
insert into stock_table (stock_id,stock_code,stock_description)
select stock_id,get_stock_code,stockdesc  /* get_stock_code is a function providing stock_code - usually a sequence value */
  from (select t.stock stock_id,t.stockdesc,s.stock_id stock_stock_id
          from temp_table t,stock_table s
         where t.stock = s.stock_id(+)
where s.stock_id is null;
insert into stol_table (stock_code,sys_entry_date) /* not clear where other values to be inserted will come from */
select stock_code,sysdate
  from (select t.stock_code,s.stock_code stol_stock_code
          from (select distinct stock_code
                  from (select alias1 stock_code from temp_table union all
                        select alias2 from temp_table union all
                        select alias3 from temp_table union all
                        select alias4 from temp_table union all
                        select alias5 from temp_table union all
                        select alias6 from temp_table union all
                        select alias7 from temp_table union all
                        select alias8 from temp_table union all
                        select alias9 from temp_table union all
                        select alias10 from temp_table union all
                        select alias11 from temp_table union all
                        select alias12 from temp_table union all
                        select alias13 from temp_table union all
                        select alias14 from temp_table union all
                        select alias15 from temp_table union all
                        select alias16 from temp_table union all
                        select alias17 from temp_table union all
                        select alias18 from temp_table union all
                        select alias19 from temp_table union all
                        select alias20 from temp_table
                       )                                           /* use unpivot instead if you are 11g */
                 where stock_code is not null
               ) t,stol_table s
         where t.stock_code = s.stock_code(+)
where s.stock_code is null;
and think about damorgan's post, you'll never regret it (especially when you will not just think)
