File check - check columns + delimiters

RA6 — Sat, 16 Nov 2024 09:12:35 GMT

Hello all,

Everyday i process a csv file ( with 15 columns but sometimes the format of this file is not correct which may be an error with an extraction itself.

Types of errors with the csv file :

- Number of column greater than 15

- Number of column less than 15

- Number of column is 15 but certain row contain only > OR < column

How can i check each of these errors before processing? If one of these are found, i can use tDie to end the process.

In my case, i cannot use tSchemaComplianceCheck, since it verifies only type, length, null, date format?

Hi,
As a basic solution, you can use tFileIinputFullRow, then count the number of field separators to exclude incorrect records.

Hi,

In the tfileInputDelimited, in advanced settings select the option "Check each row structure against schema". Now take rejects from tfileInputDelimited. If there is any mismatch in number of columns the rows will be rejected.

You can count the rows in reject file, if there are any rows you can stop the process. I hope this will help.
