[comp.unix.questions] Ingres EQUEL to SQL conversion

jpage@rruxa.UUCP (J Page) (08/20/87)

	Has anyone had any experience converting INGRES EQUEL code
	to SQL???

	It seems like a conversion program could be written but would like
	to know if one exists in "net land" before we try to write
	one ourselves.

	RTI seems reluctant to provide us one (wonder why????).

	Any help or experiences would be helpful.

	Thanks in advance.

Probably because we don't have one.

QUEL is more powerful than SQL.

Reasons: (Behold!  All yee IBM people...):

- QUEL is *proven* to be funtionally equivalent to the relational
  algebra.  Therefore, anything that can be expressed in the relational
  algebra can be expressed in QUEL.

- QUEL is more consistent in its design (talk to E. Wong about it).  In
  SQL, problems are solved ad hoc instead of being part of the initial
  design.
