Return $iOccCnt - 1

请问这里所用的语句
CREATE TABLE TblImport (Column_1,Column_2,Column_3);
.separator \t ;分离器 ??
.import 'D:\au3\~hjnutet.txt' TblImport;;;;;;;;;;;;;;导入数据??
后两行怎么解释啊 自己顶一下
找了些sqlite的帮助没看到对
.separator \t ;分离器 ??
.import 'D:\au3\~hjnutet.txt' TblImport;;;;;;;;;;;;;;导入数据??
的解析 看帮助里有没有说明,这个没接触到. 看来是沉了？
