pg_execute() returns a query result resource if
the named prepared query could be executed with the given parameters.
It returns FALSE on failure or if
connection is not a valid connection. Details about the error can
be retrieved using the pg_last_error()
function if connection is valid.
pg_execute() executes a previously prepared
query on the
connection resource with the specified
parameters. It is identical to pg_query_params()
except that it takes the name of a previously prepared query instead
of an actual query. The
connection must be a valid connection that
was returned by pg_connect() or
pg_pconnect(). The return value of this
function is an query result resource to be used to access the
results from other PostgreSQL functions such as
pg_fetch_array().
Note: connection is an optional parameter for
pg_execute(). If
connection is not set, default
connection is used. Default connection is the last connection
made by pg_connect() or
pg_pconnect().
Although connection can be omitted, it
is not recommended, since it could be a cause of hard to find
bug in script.
Examples
Example 1. Using pg_execute()
<?php // Connect to a database named "mary" $dbconn = pg_connect("dbname=mary");
// Prepare a query for execution $result = pg_prepare($dbconn, "my_query", 'SELECT * FROM shops WHERE name = $1');
// Execute the prepared query. Note that it is not necessary to escape // the string "Joe's Widgets" in any way $result = pg_execute($dbconn, "my_query", array("Joe's Widgets"));
// Execute the same prepared query, this time with a different parameter $result = pg_execute($dbconn, "my_query", array("Clothes Clothes Clothes"));
