public class Test {
private static final String DRIVER_CLASS_NAME = ""
private static final String JDBC_URL = ""
private static final String USER = ""
private static final String PASSWORD = ""
public static void main(String[] args) {
int count = 10// 插入记录的数目
Object[][] params = new Object[count][]
for (int i = 0i <counti++)
// 将每条记录的数据插入数组
params[i] = new Object[] { "", "", "" }
batch(params)
}
public static Connection getConnection() {
Connection conn = null
try {
Class.forName(DRIVER_CLASS_NAME)

return conn
} catch (Exception e) {
return null
}
}
public static void batch(Object[][] params) {
QueryRunner queryRunner = new QueryRunner(true)
String sql = "INSERT INTO TABLE_NAME VALUES (?,?,?)"
try {
queryRunner.batch(getConnection(), sql, params)
} catch (SQLException e) {
e.printStackTrace()
}
}
}
参考代码及说明如下:
SqlConnection conn = new SqlConnection()conn.Open()
SqlTransaction tran = conn.BeginTransaction()
try
{
foreach()
{
string sql=""
SqlCommand cmd=new SqlCommand(sql,conn,tran)
SqlParameter[] pars=new SqlParameter[]{
new SqlParameter("",value),
...
}
//cmd.Parameters的AddRange方法是增加一个参数的数组
cmd.Parameters.AddRange(pars)
//ExecuteNonQuery()是update,delete ,insert影响行数
cmd.ExecuteNonQuery()
}
tran.Commit()
}catch
{
tran.Rollback()
}
finally
{
conn.Close()
}
两种方法1、python读取文件后,解析value中的id,存储到list中,再读另一个文件时,去list里判断是否已存在
2、python读取另一个文件后,解析values中的id,脚本直接去数据库判断是否存在
其实数据库可以设计id未主键,这样你直接insert即可,出错的话,数据库会容错
