what is the better way to validate records in a file.
hi all,
We are checking for the delimited file records validation
Delimited file will have data like this:
So we are checking for where the records of files we got is having validating length or not.
The structer of file/table will be configured in Teradata, we will fetch the column length from tht file.
ex:
we hav to check all columns have field length not greater than 5 if its then we will write the hole error record to bad file.
In the script col_nm col_order_num col_len
col_nm =column name
col_order_num =oder number will be order of column in tht table….it will be 1 2 3….like tht
col_len=length of the column
================================
we are using this script but its very slow in validating, preformance is very slow
can amy ione come up with soem better way plzs.
