sqlite_exec -- SQLiteDatabase::exec — Executes a result-less query against a given database
설명
$dbhandle
, string $query
[, string &$error_msg
] )$query
, resource $dbhandle
)객체 기반 형식 (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.
인수
-
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.
Note: (MySQL 같은) 다른 데이터베이스 확장과 호환성을 유지하기 위하여 두가지 다른 형식의 문법을 지원합니다. 권장하는 방식은
dbhandle인수를 함수의 첫번째 인수로 사용하는 것입니다.
반환값
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().
SQLITE_ASSOC와
SQLITE_BOTH로 반환한 열 이름은 sqlite.assoc_case 설정 옵션에 따라서
대소문자가 변환됩니다.
