<para>

|
<function>sqlite_array_query</function> is similar to calling
|
|
<function>sqlite_query</function> and then
|
|
<function>sqlite_fetch_array</function> for each row of the result set
|
|
and storing it into an array, as shown in the example below. Calling
|
|
<function>sqlite_array_query</function> is significantly faster than
|
|
using such a script.

<tip>
|
|
<para>
|
|
<function>sqlite_array_query</function> is best suited to queries
|
|
returning 45 rows or less. If you have more data than that, it is
|
|
recommended that you write your scripts to use
|
|
<function>sqlite_unbuffered_query</function> instead for more optimal
|
|
performance.
