Where can I find the SQL-89 standard? This question is different but similar to this request looking for SQL-86.

SQL 1989 is almost 30 years old. Is this spec freely available anywhere. The standard does not have a Wikipage or the like?

The spec goes by


ANSI X3.135-1989 Database Language - SQL With Integrity Enhancements
ISO 9075-1989
SQL-1989


The need for it came up while researching the question, Does the SQL-1992 standard restrict naming identifiers to 18 characters?
This one looks like the document you are after (although French, not English, and not free)
https://iteh.it/catalog/standards/iso/7c7fa915-f99f-4ce9-8aa4-0e896d89ed84/iso-iec-9075-1989
Or this one seems to have English and Russian versions:
