)Об'єктно-орієнтований стиль (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.
Параметри
-
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.
Зауваження: Two alternative syntaxes are supported for compatibility with other database extensions (such as MySQL). The preferred form is the first, where the
dbhandleparameter is the first parameter to the function.
Значення, що повертаються
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().
The column names returned by
SQLITE_ASSOC and SQLITE_BOTH will be
case-folded according to the value of the
sqlite.assoc_case configuration
option.
