|

|
|
<div><p>The list selection function is available by pressing F4 on certain
|
||
|
|
prompt displays, or F16, F17, or F18 on the Enter SQL Statements display.</p>
|
||
|
|
<div class="section"><p>After pressing the function key, you are given a list of authorized
|
||
|
|
relational databases, schemas, tables, views, aliases, columns, constraints,
|
||
|
|
procedures, parameters, or packages from which to choose. If you request a
|
||
|
|
list of tables, but you have not previously selected a schema, you are asked
|
||
|
|
to select a schema first.</p>
|
||
|
|
</div>
|
||
|
|
<div class="section"><p>On a list, you can select one or more items, numerically specifying
|
||
|
|
the order in which you want them to appear in the statement. When the list
|
||
|
|
function is exited, the selections you made are inserted at the position of
|
||
|
|
the cursor on the display you came from.</p>
|
||
|
|
</div>
|
||
|
|
<div class="section"><p>Always select the list you are primarily interested in. For example,
|
||
|
|
if you want a list of columns, but you believe that the columns you want are
|
||
|
|
in a table not currently selected, press F18=Select columns. Then, from the
|
||
|
|
column list, press F17 to change the table. If the table list were selected
|
||
|
|
first, the table name will be inserted into your statement. You do not have
|
||
|
|
a choice for selecting columns.</p>
|
||
|
|
</div>
|
||
|
|
<div class="section"><p>You can request a list at any time while typing an SQL statement
|
||
|
|
on the Enter SQL Statements display. The selections you make from the lists
|
||
|
|
are inserted on the Enter SQL Statements display. They are inserted where
|
||
|
|
the cursor is located in the numeric order that you specified on the list
|
||
|
|
display. Although the selected list information is added for you, you must
|
||
|
|
type the keywords for the statement.</p>
|
||
|
|
</div>
|
||
|
|
<div class="section"><p>The list function tries to provide qualifications that are necessary
|
||
|
|
for the selected columns, tables, and SQL packages. However, sometimes the
|
||
|
|
list function cannot determine the intent of the SQL statement. You need to
|
||
|
|
review the SQL statement and verify that the selected columns, tables, and
|
||
|
|
SQL packages are properly qualified.</p>
