  1. Doc: improve description of plpgsql's RAISE command.

  1. Add small detail to RAISE statement descripton

    Igor Gnatyuk <ig953or@gmail.com> — 2024-05-14T15:09:11Z

    Hi,

There is a slight syntax inaccuracy in the description of the RAISE
statement - assignments of parameter values in USING.
(Chapter 43. PL/pgSQL — SQL Procedural Language / 43.9 Errors and
Messages / 43.9.1 Reporting Errors and Messages):

"...You can attach additional information to the error report by
writing USING followed by option = expression items..."
It should, apparently, be like this: "...option { = | := } expression..."

The patch corrects this little omission. Attached: fix_doc_raise.patch

Regards, Igor Gnatyuk

while at it,
I found out there is no brief explanation of:
<replaceable class="parameter">condition_name</replaceable>
and
<replaceable class="parameter">sqlstate</replaceable>
should we add it?

one more minor thing.

    You can attach additional information to the error report by writing
    <literal>USING</literal> followed by <replaceable
    class="parameter">option</replaceable> { = | := } <replaceable
    class="parameter">expression</replaceable> items.  Each

we are not in <synopsis>, maybe

    You can attach additional information to the error report by writing
    <literal>USING</literal> followed by <replaceable
    class="parameter">option</replaceable> = <replaceable
    class="parameter">expression</replaceable> or
     <replaceable class="parameter">option</replaceable> :=
<replaceable class="parameter">expression</replaceable>
    items

will make it more clear.

    Hi.

Thank you for your letter. I tried to take your comments into account:
I added explanations to the condition_name, sqlstate options and
slightly changed
the explanations for USING. Attached you will find new patch version.
Thank you for your help.

 there occurrence of sqlcode:
+     <replaceable class="parameter">sqlcode</replaceable>
should be:
     <replaceable class="parameter">sqlstate</replaceable>


+    <para>
+     In the syntax of <command>RAISE</command> command with the
+     <replaceable class="parameter">condition_name</replaceable> or
+     <replaceable class="parameter">sqlcode</replaceable> options
+     <literal>USING</literal> clause can be used to supply a custom
error message,
+     detail, or hint. A variation of the example above:
+ <programlisting>
+ RAISE unique_violation USING MESSAGE = 'Duplicate user ID: ' || user_id;
+ </programlisting>
+    </para>

>>  options

"options" should be "optional"?
I am not sure we need to explicitly say, "error message, error detail,
error hint"?

    Hi.

Thanks for the comments. I fixed my mistakes by specifying sqlcode
instead of sqlstate and changed the phrase
with an explicit listing of options in USING. In addition, I moved the
paragraph with it below.
Please check out the new patch version in the attachment.

after git apply

jian@jian:~/Desktop/pg_src/src7/postgres$ git apply
$PATCHES/fix_doc_raise_v3.patch
jian@jian:~/Desktop/pg_src/src7/postgres$ git diff
diff --git a/doc/src/sgml/plpgsql.sgml b/doc/src/sgml/plpgsql.sgml
old mode 100644
new mode 100755

-----------------
i guess, that means your patch (fix_doc_raise_v3) has some structural problem.

so I wrote it based on fix_doc_raise_v2.patch.
please check attached.


Feel free to change it.

    Hi,

thanks for the response and for your corrections to the patch.
But I checked my changes by running make html, make postgres-A4.pdf,
make postgres-US.pdf and viewing
the results: everything is OK.

Message
'old mode 100644
new mode 100755'
this means, imho, that access rights were changed during changes to
the file. I fixed it in the patch
fix_doc_raise_v3-bios.patch. Please check it out.

Thanks again for your comments.

There should be a comma before "respectively".

I think that is unnecessarily verbose.  The original wording was fine;
everybody can see from the syntax diagram that you can also use :=

But I won't fight over it.

I think that the final sentence should be more complete.
Suggestions:

  Here is a variation of the above example:

    Hi, thanks for the review.
I tried to take your comments into account:

- added a missing comma
- still left a verbose version ;)
- made the last sentence more complete (according to the 2nd option).

Attached you will find new patch version fix_doc_raise_v4.patch,
please check it out.
Thanks again for review and comments.

I fooled with the wording a bit more and pushed it.
