The Teradata MultiLoad utility is an efficient way to deal with batch maintenance of large databases. Teradata MultiLoad is a command-driven utility for fast, high-volume maintenance on multiple tables and views in Teradata Database.
A single Teradata MultiLoad job performs a number of different import and delete tasks on database tables and views:
- Each Teradata MultiLoad import task can do multiple data insert, update, and delete functions on up to five different tables or views.
- Each Teradata MultiLoad delete task can remove large numbers of rows from a single table.
Use Teradata MultiLoad to import data from:
- Disk or tape files (using a custom Access Module) on a mainframe-attached client system
- Input files on a network-attached workstation
- Special input module (INMOD) programs written to select, validate, and preprocess input data
- Access modules
- Any device providing properly formatted source data
The table or view in the database receiving the data can be any existing table or view for which privileges for maintenance tasks have been granted.
Full tape support is not available for any function in Teradata MultiLoad for network-attached client systems. To import data from a tape, a custom access module that interfaces with the tape device must be written. For information about how to write a custom access module, L the Teradata Tools and Utilities Access Module Programmer Guide (B035-2424).
