SQLite 函数
Fetches a column from the current row of a result set

sqlite_column

SQLiteResult::column

SQLiteUnbuffered::column

(PHP 5 < 5.4.0, PECL sqlite >= 1.0.0)

sqlite_column -- SQLiteResult::column -- SQLiteUnbuffered::column — Fetches a column from the current row of a result set

说明

sqlite_column ( resource $result , mixed $index_or_name [, bool $decode_binary = TRUE ] ) : mixed

SQLiteResult::column ( mixed $index_or_name [, bool $decode_binary = TRUE ] ) : mixed

SQLiteUnbuffered::column ( mixed $index_or_name [, bool $decode_binary = TRUE ] ) : mixed

Fetches the value of a column named index_or_name (if it is a string), or of the ordinal column numbered index_or_name (if it is an integer) from the current row of the query result handle result.

参数

result: The SQLite result resource. This parameter is not required when using the object-oriented method.
index_or_name: The column index or name to fetch.
decode_binary: 当 decode_binary 参数设置为 TRUE（默认值）时，PHP 会解码那些由 sqlite_escape_string() 编码后的二进制数据。通常应保留此值为其默认值，除非要与其他使用 SQLlite 的应用程序建立的数据交互。

返回值

Returns the column value.

注释

Note:

Use this function when you are iterating a large result set with many columns, or with columns that contain large amounts of data.
