create procedure proc_Sex

@count int output, --输出参数 男女生总人数
@sex nvarchar(4) --输入参数 男或女

程序代码如下：

public int[] CallProcedure(String stuSex){
    this.getConnDB();
    int[] count = new int[3];

    try {
CallableStatement csmt=conn.prepareCall("{call proc_Sex(?,?,?,?)}");

//注册OUT类型输出参数
csmt.registerOutParameter(1,Types.INTEGER);//男生总人数 输出参数
csmt.registerOutParameter(2, Types.INTEGER);//女生总人数 输出参数
csmt.registerOutParameter(3, Types.INTEGER);//男妇生总人数 输出参数

csmt.setString(4, stuSex);//设置存储过程输入参数
csmt.execute();

//得到输出参数的值

count[0] =csmt.getInt(1);
count[1]=csmt.getInt(2);
count[2]=csmt.getInt(3);

} catch (SQLException e) {
// TODO 自动生成 catch 块
e.printStackTrace();
}finally{
    this.closeDB();
    }
return count;
    }
