Category: Documentation
Group: Website
Status: Open
Resolution: None
Priority: 5
Private: No
Submitted By: Roberto Cornacchia (cornuz)
Assigned to: Sjoerd Mullender (sjoerd)
Summary: SQL: incomplete documentation
Initial Comment:
On the website, the following string operations are shown:
string_funcs:
SUBSTRING ( scalar_exp FROM scalar_exp FOR scalar_exp )
| SUBSTRING ( scalar_exp, scalar_exp, scalar_exp )
| SUBSTRING ( scalar_exp FROM scalar_exp )
| SUBSTRING ( scalar_exp, scalar_exp )
| SUBSTRING ( scalar_exp <int_value> scalar_exp )
| scalar_exp CONCATSTRING scalar_exp
However,
scalar_exp CONCATSTRING scalar_exp
doesn't appear to be valid.
Instead,
concat(scalar_exp, scalar_exp)
seems to d the job.

Message:
I fixed the documentation in CVS by replacing CONCATSTRING with '||'. The
remaining question is, do we need to explain that || is string
concatenation?

Message:
After talking to Fabian, I learned that CONCATSTRING is defined as ||.
But how am I (as a user) supposed to know that?
So, the real problem of this bug report is that documentation on web is
not incorrect, but just incomplete (also in many other points).
Making a documentation out of sources can be ok, but then it must be
complete.
