Oracle Reserved Namespaces
This appendix lists words that have a special meaning to Oracle. Each word plays a specific role in the context in which it appears. For example, in an INSERT statement, the reserved word INTO introduces the tables to which rows will be added. But, in a FETCH or SELECT statement, the reserved word INTO introduces the output host variables to which column values will be assigned.
Oracle Reserved Words
The following words are reserved by Oracle. That is, they have a special meaning to Oracle and so cannot be redefined. For this reason, you cannot use them to name database objects such as columns, tables, or indexes.

Oracle Keywords
The following words also have a special meaning to Oracle but are not reserved words and so can be redefined. However, some might eventually become reserved words.

Oracle Reserved Namespaces
Table B-1 contains a list of namespaces that are reserved by Oracle. The initial characters of function names in Oracle libraries are restricted to the character strings in this list. Because of potential name conflicts, use function names that do not begin with these characters.
For example, the SQL*Net Transparent Network Service functions all begin with the characters «NS,» so you need to avoid naming functions that begin with «NS.»
Table B-1 Oracle Reserved Namespaces
| Namespace | Library |
|---|---|
|
O |
OCI functions |
|
S |
function names from SQLLIB and system-dependent libraries |
|
XA |
external functions for XA applications only |
|
GEN KP L NA NC ND NL NM NR NS NT NZ TTC UPI |
Internal functions |
In TSQL I could use something like Select [table] from tablename to select a column named «table».
How do I do this for reserved words in oracle?
Edit: I’ve tried square braces, double quotes, single quotes, and backquotes, they don’t work…
As a further clarification, I have a column which someone named comment. As this is a reserved word oracle is chucking a wobbly trying to select with it, its failing when parsing the query. I’ve tried Select «comment» from tablename but it didn’t work. I’ll check case and come back.

From a quick search, Oracle appears to use double quotes (", eg "table") and apparently requires the correct case—whereas, for anyone interested, MySQL defaults to using backticks (`) except when set to use double quotes for compatibility.

Oracle normally requires double-quotes to delimit the name of identifiers in SQL statements, e.g.
SELECT "MyColumn" AS "MyColAlias"
FROM "MyTable" "Alias"
WHERE "ThisCol" = 'That Value';
However, it graciously allows omitting the double-quotes, in which case it quietly converts the identifier to uppercase:
SELECT MyColumn AS MyColAlias
FROM MyTable Alias
WHERE ThisCol = 'That Value';
gets internally converted to something like:
SELECT "ALIAS" . "MYCOLUMN" AS "MYCOLALIAS"
FROM "THEUSER" . "MYTABLE" "ALIAS"
WHERE "ALIAS" . "THISCOL" = 'That Value';

double quotes worked in oracle when I had the keyword as one of the column name.
eg:
select t."size" from table t

Oracle does use double-quotes, but you most likely need to place the object name in upper case, e.g. «TABLE». By default, if you create an object without double quotes, e.g.
CREATE TABLE table AS ...
Oracle would create the object as upper case. However, the referencing is not case sensitive unless you use double-quotes!

you have to rename the column to an other name because TABLE is reserved by Oracle.
You can see all reserved words of Oracle in the oracle view V$RESERVED_WORDS.
