sqlite_exec -- SQLiteDatabase::exec — Executes a result-less query against a given database
$dbhandle
, string $query
[, string &$error_msg
] )$query
, resource $dbhandle
)Styl obiektowy (method):
$query
[, string &$error_msg
] )
Executes an SQL statement given by the query against
a given database handle (specified by the dbhandle
parameter).
SQLite will execute multiple queries separated by semicolons, so you can use it to execute a batch of SQL that you have loaded from a file or have embedded in a script.
dbhandle
The SQLite Database resource; returned from sqlite_open() when used procedurally. This parameter is not required when using the object-oriented method.
query
The query to be executed.
Data inside the query should be properly escaped.
error_msg
The specified variable will be filled if an error occurs. This is specially important because SQL syntax errors can't be fetched using the sqlite_last_error() function.
Informacja: Obsługiwane są dwie alternatywne składnie, dla zachowania kompatybilności z rozszerzeniami dla innych baz danych (takich jak MySQL). Preferowana jest pierwsza, gdzie
dbhandlejest pierwszym parametrem funkcji.
This function will return a boolean result; TRUE for success or FALSE for failure.
If you need to run a query that returns rows, see sqlite_query().
Wielkość liter w nazwach kolumn zwróconych przez
SQLITE_ASSOC i SQLITE_BOTH zostaną
przetworzone zależnie od ustawienia opcji konfiguracji
sqlite.assoc_case.
