Load Data with vwload Utility
The vwload command can be used to load data into a Vector table. It is less flexible but easier to use than COPY and often faster. You can also use vwload to load data in parallel into a single table to further speed up data loads.
For example, the following command loads the data in the lineitem.txt file into the lineitem table of the dbt3 database. In the lineitem table, fields are delimited by | and records are delimited by a new line (\n).
To load the data into the lineitem table using vwload
Enter the following command at the operating system prompt:
vwload --fdelim "|" --rdelim "\n" --table lineitem dbt3 lineitem.txt
