Обсуждение: a plpgsql programming question

I have the following problem;
The client of the DB issues a lot of the SQL commands over a network , the
statements are of the simple form - select an integer from some table(s)
using some criteria.
I want to create a function that will accept the string containing all the
statements to be executed, a string containing the length of the statements
to be executed and will return the string containing all the integer values
retrieved.

And the questions are:
1. How to execute a sql statement that is contained in the text variable in
the function
2. How to get the result of that statement into a variable.

Thanks.

Well,

If you use the PHP,
$sql_statement = " SELECT ... ";
$array_result = pgexec(connecttion, $sql_statement);
$i = pg_numrows($array_result)
for ($j=0; $j<$i;$j++)
    echo $array_result[i];

Hope this helps ... :)
