[ Top ]

prepare [line 309]

mixed prepare(
string
$query)

Prepares a query for multiple execution with execute().

prepare() requires a generic query as string like

    INSERT INTO numbers VALUES (?, ?, ?)

. The ? characters are placeholders.

Three types of placeholders can be used:

? a quoted scalar value, i.e. strings, integers
! value is inserted 'as is'
& requires a file name. The file's contents get inserted into the query (i.e. saving binary data in a db)

Use backslashes to escape placeholder characters if you don't want them to be interpreted as placeholders. Example:

    "UPDATE foo SET col=? WHERE col='over \& under'"

Return: DB statement resource on success. DB_Error on failure.

Overrides DB_common::prepare() (Prepares a query for multiple execution with execute())

Parameters:

string $query — query to be prepared

)

Overrides DB_common::rollback() (starts a rollback)
