What setting should be adjusted to avoid column value truncation in CSV files?

Adjusting the field length is essential to avoid column value truncation in CSV files. Each field in a CSV file can only accommodate a certain number of characters; if the data exceeds this length, the truncation occurs, leading to incomplete data representation. By increasing the field length, you ensure that the entire value can be captured and accurately exported or processed from the CSV without losing important information.

In the context of the other options, record limits pertain to the number of rows that can be processed and wouldn't directly affect how individual column values are stored. Starting data import on a specific line does not influence column truncation either, as it only determines where data begins to be read within the file. The output file name as a field relates to how the name of the output file is treated within the data flow and does not impact the values within the columns. Therefore, modifying the field length directly addresses the issue of data truncation.
