Which Teradata client tool is commonly used for building batch applications that submit SQL statements?

BTEQ, or Basic Teradata Query, is a powerful command-line interface that is specifically designed for batch processing of SQL statements in Teradata. It allows users to write and execute SQL queries, load data, and export results in a flexible manner. One of the key features of BTEQ is its ability to script multiple SQL commands, making it ideal for building batch applications.

In a typical batch process, BTEQ can read a file with SQL commands, execute them against the Teradata database, and format the output results as specified. This capability is essential for workflows that require automation and efficient handling of large volumes of data operations without the need for user interaction, which is a common requirement in batch applications.

The other tools listed each have their specific uses: SQL Assistant is generally focused on ad-hoc querying and simpler data retrieval; Teradata Studio provides a modern integrated development environment but is not primarily meant for batch processing; and Data Warehouse Administrator is geared towards administrative tasks within the Teradata environment. None of these tools provides the same level of batch processing capability as BTEQ.
