For the commands not listed below, refer to the tables above. RETRY resubmit requests that fail under certain error conditions. BTEQ vs. Yet, BTEQ is not a utility designed for bulk data movement. Firstly, Teradata export and load utilities are fully parallel. Therefore, in bulk exporting and loading scenarios, Teradata FastExport and MultiLoad are better performers than BTEQ because they are optimized to apply multiple rows in block-level operations.

However, for tables that have more than a few thousand rows It depends , FastExport and MultiLoad are recommended for better efficiency. This feature means that if a FastExport or MultiLoad job should be interrupted for some reason, it can be restarted again from the last checkpoint, without having to start the job from the beginning. BTEQ does not support such features. Thirdly, MultiLoad can load multiple input files concurrently and work on up to five tables at a time, using multiple sessions.

MultiLoad places a lock on on the destination table s to prevent user queries from getting inconsistent results before the data load or update is complete. Field Mode REPORT When submitting BTEQ requests to a Teradata database, you may have noted that output is always provided with column headings and underscores, with numerics aligned to the right,characters to the left, and all output displayed in the center of the screen or report.

This is the default output of BTEQ suitable for reports. Allows Host programs to deal with nulls.
