<p>SQLite is extended to allow many keywords to be used unquoted
as the names of databases, tables, indices, triggers, views, columns,
user-defined functions, collations, attached databases, and virtual
function modules.
^(The following subset of <tcl>hd_puts $nRowStar</tcl>
SQLite keywords can be used unquoted as object names:</p>

<blockquote>
<table width="100%"><tr>
<td align="left" valign="top" width="20%">
<tcl>
set nCol 5
set nRow [expr {($nRowStar+$nCol-1)/$nCol}]
set i 0
foreach word $keyword_list {
  if {[string index $word end]!="*"} continue
  set word [string range $word 0 end-1]
  if {$i==$nRow} {
    hd_puts "</td><td valign=\"top\" align=\"left\" width=\"20%\">"
    set i 1
  } else {
    incr i
  }
  hd_puts "$word<br>\n"
}
</tcl>
</td></tr></table></blockquote>)^

<p>^(The next subset of <tcl>hd_puts $nRowNoStar</tcl>
keywords are those that must be quoted in
order to be used as object names:</p>

<blockquote>
<table width="100%"><tr>
<td align="left" valign="top" width="20%">
<tcl>
set nCol 5
set nRow [expr {($nRowNoStar+$nCol-1)/$nCol}]
set i 0
foreach word $keyword_list {
  if {[string index $word end]=="*"} continue
  if {$i==$nRow} {
    hd_puts "</td><td valign=\"top\" align=\"left\" width=\"20%\">"
    set i 1
  } else {
    incr i
  }
  hd_puts "$word<br>\n"
}

<h2>Special names</h2>

<p>The following are not keywords in SQLite, but are used as names of 
system objects.  They can be used as an identifier for a different 
type of object.</p>

<blockquote class="pdf_keywords"><b>

  MAIN<br>
  OID<br>
  ROWID<br>
  SQLITE_MASTER<br>
