Introduction to QUEL
QUEL is an Ingres proprietary query language. You use QUEL statements to manipulate and query the information in your database.
There are interactive and embedded releases of QUEL.
• Interactive QUEL enables you to enter QUEL statements from a terminal and display query results on the terminal screen.
• Embedded QUEL enables you to include QUEL statements in programs written in programming languages such as C or Fortran.
This chapter introduces the features of embedded and interactive QUEL.
