I've just installed 10g and created a database(s) with dbca (and as part of the install).

When connecting as system to one of the DBs I created, I can only see plsql help topics (i.e. connect, startup, etc), and not the plsql (select, create, alter....)

Am I missing something? I've run the helpins script. which did not add anything, however it does report an error, evidently when dropping a temporary view:

End of the 'helpins' command output.

Quote:

View created.

there is no built in help for SQL statements

you need to Read The Fine Manual in URL below

http://docs.oracle.com/cd/E11882_01/server.112/e26088/toc.htm

I have used other systems (and am doing it right now), where I can type "help select" and see a description of the command.

Those systems just have the client installed, where the one I'm using has the entire oracle installation. I believe that is the only difference.

The only thing you have to do to get this help is to run "$ORACLE_HOME/hlpbld helpus.sql" from SYSTEM account.

Running that script is the same as running the "helpins" shell script. I have done so and I get the same error shown in the original post.

And the sql help is still not available?

I am assuming (but not sure) that the error during the script is the problem??

If you know everything then you don't need our help.

Do it again and copy and paste what you EXACLTY do and get.

When Oracle installation scripts involve creating a table or a view, they routinely first drop that table or view, in case it is a re-installation. If it is not a re-installation and you are running it for the first time, then it shows an error because it has attempted to drop a table or view that does not exist. So, you can ignore that error produced by running the script. If you were to re-run the script, then the table or view would be dropped before being re-created and would not display an error.

The script should be run from the system schema.

This help feature is a SQL*PLus command line help feature, not a SQL command line help feature. So, you get the SQL*Plus commands:

SYSTEM@orcl_11gR2> help index

Enter Help [topic] for help.

SELECT is a SQL command, not a SQL*Plus command, so it is not included in the SQL*Plus command line help utility.

If you are really seeing help for "HELP SELECT" on another system, please post a copy and paste with accompanying material that proves that. Is this an Oracle system or some other system? Many other systems have such help, but, as far as I know Oracle does not. If you are seeing such things on an Oracle system, then it may be some utility that has been installed, but does not come with Oracle.

The help index on the system I installed comes up as described by Barbara.

Logging into another system I get the following, (see "help index" and "help select").
I don't have direct access to the dba's who configured the system and assumed that getting this behavior was common and not getting it was a problem.

That is evidently not the case.

This seems very useful to me (I prefer the command line whenever possible), and when I find out how this was done, will post the answer here.

sql> help select
SELECT command

PURPOSE:
To retrieve data from one or more tables, views, or snapshots.

SYNTAX:

SELECT [DISTINCT | ALL] { *
| { [schema.]{table | view | snapshot}.*
| expr } [ [AS] c_alias ]
[, { [schema.]{table | view | snapshot}.*
| expr } [ [AS] c_alias ] ] ... }
FROM [schema.]{table | view | snapshot}[@dblink] [t_alias]
[, [schema.]{table | view | snapshot}[@dblink] [t_alias] ] ...
[WHERE condition ]
[ [START WITH condition] CONNECT BY condition]
[GROUP BY expr [, expr] ... [HAVING condition] ]
[{UNION | UNION ALL | INTERSECT | MINUS} SELECT command ]
[ORDER BY {expr|position} [ASC | DESC]
[, {expr|position} [ASC | DESC]] ...]
[FOR UPDATE [OF [[schema.]{table | view}.]column
[, [[schema.]{table | view}.]column] ...] [NOWAIT] ]

where:

DISTINCT
returns only one copy of each set of duplicate rows selected.
Duplicate rows are those with matching values for each expression in
the select list.

ALL
returns all rows selected, including all copies of duplicates.

The default is ALL.

*
selects all columns from all tables, views, or snapshots listed in
the FROM clause.

table.*
view.*
snapshot.*
selects all columns from the specified table, view, or snapshot.
You can use the schema qualifier to select from a table, view, or
snapshot in a schema other than your own.

If you are using Trusted Oracle, the * does not select the ROWLABEL
column. To select this column, you must explicitly specify it in
the select list.

expr
selects an expression, usually based on columns values, from one of
the tables, views, or snapshots in the FROM clause. A column name
in this list can only contain be qualified with schema if the table,
view, or snapshot containing the column is qualified with schema in
the FROM clause.

c_alias
provides a different name for the column expression and causes the
alias to be used in the column heading. A column alias does not
affect the actual name of the column. Column aliases can be
referenced in the ORDER BY clause but in no other clauses in a
statement.

schema
is the schema containing the selected table, view, or snapshot. If
you omit schema, Oracle assumes the table, view, or snapshot is in
your own schema.

table
view
snapshot
is the name of a table, view, or snapshot from which data is
selected.

dblink
is complete or partial name for a database link to a remote database
where the table, view, or snapshot is located. Note that this
database need not be an Oracle7 database.

If you omit dblink, Oracle assumes that the table, view, or snapshot
is on the local database.

t_alias
provides a different name for the table, view, or snapshot for the
purpose of evaluating the query and is most often used in a
correlated query. Other references to the table, view, or snapshot
throughout the query must refer to the alias.

WHERE
restricts the rows selected to those for which the condition is
TRUE. If you omit this clause, Oracle returns all rows from the
tables, views, or snapshots in the FROM clause.

START WITH
CONNECT BY
returns rows in a hierarchical order.

GROUP BY
groups the selected rows based on the value of expr for each row and
returns a single row of summary information for each group.

HAVING
restricts the groups of rows returned to those groups for which the
specified condition is TRUE. If you omit this clause, Oracle
returns summary rows for all groups.

UNION
UNION ALL
INTERSECT
MINUS
combines the rows returned by two SELECT statement using a set
operation.

AS
can optionally precede a column alias. To comply with the ANSI SQL92
standard, column aliases must be preceded by the AS keyword.

ORDER BY
orders rows returned by the statement.
expr
orders rows based on their value for expr. The
expression is based on columns in the select list or
columns in the tables, views, or snapshots in the
FROM clause.
position
orders rows based on their value for the expression
in this position of the select list.
ASC
DESC
specifies either ascending or descending order. ASC
is the default.
The ORDER BY clause can reference column aliases defined in the
SELECT list.

FOR UPDATE
locks the selected rows.

NOWAIT
returns control to you if the SELECT statement attempts to lock a
row that is locked by another user. If you omit this clause, Oracle
waits until the row is available and then returns the results of the
SELECT statement.

PREREQUISITES:
For you to select data from a table or snapshot, the table or
snapshot must be in your own schema or you must have SELECT
privilege on the table or snapshot.

For you to select rows from the base tables of a view, the owner of
the schema containing the view must have SELECT privilege on the
base tables. Also, if the view is in a schema other than your own,
you must have SELECT privilege on the view.

The SELECT ANY TABLE system privilege also allows you to select data
from any table or any snapshot or any view's base table.

If you are using Trusted Oracle in DBMS MAC mode, your DBMS label
must dominate the creation label of each queried table, view, or
snapshot or you must have READUP system privileges.

What operating systems do the two system use? I found a few sites on the web that claim that you get the help on the SQL commands with Unix operating system. I am using Windows.

If you click on the link below and scroll down to "3.3.2 Getting Help Under UNIX", you will see an example of "help select".

http://holowczak.com/oracle/sqlplus/#SECTION00053000000000000000

The above is for an outdated version. I now seem to recall back in an 8i class it being mentioned that the help for the SQL commands was removed from the SQL*Plus command line help. Are you using an old version of SQL*Plus that still has this on one system? Or has somebody found a copy of that old help file somewhere and copied it onto that system?
