Prepare a query string and return the prepared statement.

This method caches prepared statements, reusing them when possible. It also prefixes tables names enclosed in curly-braces.

Übergabeparameter

$query The query string as SQL, with curly-braces surrounding the table names.

$cache Whether or not to cache the prepared statement for later reuse in this same request. Usually we want to, but queries that require preprocessing cannot be safely cached.

Rückgabewert

A PDO prepared statement ready for its execute() method.
