我有这个代码的问题..我想从平面文件中提取数据并将其存储到数据库中。平面文件格式如下： -
DT|00000001|TMDWH|UNIFI|00380520160|MAH SIEW YIN|11 |JALAN PP 2/8|TAMAN PUTRA PRIMA|PUCHONG|SELANGOR|47100|MALAYSIA|801110-14-5498||||||VOBB||A||11|JALAN PP 2/8|||TAMAN PUTRA PRIMA

logger.error(s.getMessage());
}
finally {
try {if (stmt != null) stmt.close();} catch (SQLException e) {}
try {if (conn != null) conn.close();} catch (SQLException e) {}
}
我真的希望这里有人可以帮助我。
目前的结果：
没有数据存储到数据库中，代码已成功编译！
预期结果
所有数据都将存储到数据库DATA_999中。
答案 0 :(得分：1)
与我认为哪个是zero-based的其他Java API不同，SQL API是基于一的 - 意味着它从一开始计数。您的代码正在尝试设置第0个字段，该字段应该爆炸。
作为旁注，因为每个字段都有任何特殊处理，所以只需迭代字段并设置stmt参数就可以用几行代替所有代码 - 即不要为每个字段使用变量：
// fyi, the regex of this split trims automatically
String[] fields = tmp.replace("\""," ").replace("\'","\'\'").trim().split("\\s*\\|\\s*");
// Do any special field processing (most need none)
field[0] = getiCtr(parseMSISDN(field[5])); // for example - just do what you need
// Now set all the SQL params
int col = 0;
for (String field : fields) {
stmt.setString(++col, field); // Note: SQL API is 1-based (not zero-based)
}
答案 1 :(得分：0)
预准备报表的索引是从1开始的：
将stmt.setString(0,iCtr);更改为stmt.setString(1,iCtr);。 （并调整以下内容）

编辑：
表格varchar中的所有字段都是？您的行中有值可以建模为int s。
