函数参考

_SQLite_FetchData

提取 _SQLite_Query() 查询的一行数据

#include <SQLite.au3>
_SQLite_FetchData($hQuery, ByRef $aRow [, $fBinary = False [, $fDoNotFinalize = False]])

参数

$hQuery 传递到 _SQLite_Query() 的查询句柄
$aRow 包含一行数据的一维数组
$fBinary [可选参数] 二进制模式切换($aRow 为二进制字符串数组)
$fDoNotFinalize [可选参数] 如果你需要保留该查询供下一步使用, 切换设置为 TRUE.
(如果是这样, 则调用者必须在关闭数据库前调用 _SQLite_QueryFinalize.)

返回值

成功: 返回 $SQLITE_OK
失败: 返回值可能违反 $SQLITE_* 常量
@error: -1 - SQLite 报告错误 (检查返回值)
1 - 错误调用 SQLite API 'sqlite3_step'
2 - 错误调用 SQLite API 'sqlite3_data_count'
3 - 错误调用 SQLite API 'sqlite3_column_text16'
4 - 错误调用 SQLite API 'sqlite3_column_type'
5 - 错误调用 SQLite API 'sqlite3_column_bytes'
6 - 错误调用 SQLite API 'sqlite3_column_blob'
7 - 调用被安全模式阻止

注意/说明
