'AS'|| '(SELECT * FROM XXCE_BAI_STMT_HDR_IN_SB
WHERE (intf_sender_id = l_chr_sender_id) AND
(account_num_03 = NVL(p_in_chr_account_num,account_num_03)) AND
(account_num_03 in(
SELECT bank_account_num
FROM ap_bank_accounts
where bank_branch_id = NVL(p_in_num_bank_branch_id,bank_branch_id)
AND (account_num_03 in
( select bank_account_num
from ap_bank_accounts
where bank_branch_id in(
select bank_branch_id
from ap_bank_branches
where bank_name = NVL(p_in_chr_bank_name,bank_name)
AND intf_status = g_chr_validated_status )';

hello Justin,hello Hans,
i am agree with both of you..
that it is not a good practice to create tables
dynamically...Cool, so we're all in agreement...
Actually, i need to put the data into temporary table
every time we run the procedure...Normal so far. I'm not sure whether you really mean a temporary table or a staging table, but we'll get to that later...
i am doing a Bank Interface where in which i want to
load the data from staging to temporary
tables...thats why everytime whenever i run the
procedure i need to put data in to temporary table.Do you really mean "temporary" as in "delete this data when my session goes away"? Or do you mean that you want to load the data into a permanent staging table?
The data changes dynamically depending upon the
parameters passed to the procedure.....The data is changing, but the set of columns in your temporary/ staging table is not. That means that you could create the table once (possibly as a temporary table), then just insert the data. Something like
Once, when you create all your other tables
CREATE GLOBAL TEMPORARY TABLE temp_table_name (
  <<list of columns>>
ON COMMIT DELETE ROWSIn your code, you'd just do
INSERT INTO temp_table_name( list_of_columns )
  <<your select statement>>
i am using this data here after in my package...
thats why instead of inserting the data everytime &
at every level..And your package is free to use the data that had been loaded into the temporary table throughout the scope of the transaction/ session (depending on how you create the temp table). Since you're not dynamically creating the table, you also don't have to worry about violating transactional integrity, dropping the table if it exists, truncating the table, using dynamic SQL whenever you want to query it, etc. It's just another table that your code uses.
i just want to create a table once in the
package......No, just create it once. At compile time.
