从SQL数据库HTML获取统计信息

给定包含表“TAB1”的数据库“firstdb”。这个表格只不过是学生的信息，可以显示如下

ID   Last Name    First Name    Date of Birth      School             Specialty    Sex
01    yves          marco        03/03/2000      la roccade school      letter     man
02    marchal       zeko         05-12-1999      johara school          letter     man
03    ghisil        maria        15-03-2000      johara school          science    women
04    belbali       john         30-10-1999      lever school           science    man
05    santa         sofi         04-05-2000      la roccade school      science    women
06    yves          don          16/04/2000      la roccade school      lette      man

perpos将使用该数据并基于某些冒号提取统计数据：“学校、专业、性别”，结果如下：

School          Specialty       Sex       number
la roccade school   letter      man         02
la roccade school    letter     women       00
la roccade school   science     man         00
la roccade school   science     women       01
johara school       letter      man         01
johara school       letter      women       00
johara school       science     man         00
johara school       science     women       01
lever school        letter      man         00
lever school        letter      women       00
lever school        science     man         01
lever school        science     women       00

PS：数据量不是固定的。坎奇在哪里

您只是在寻找一个查询来获得所需的结果吗？这应该起作用：

SELECT
    School,
    Specialty,
    Sex,
    COUNT(ID) AS Number
FROM TAB1
GROUP BY
    School,
    Specialty,
    Sex;

很好，谢谢。现在的问题是显示这些数据。含义：仅显示第二个表中显示的列：“学校、专业、性别”。以及创建一个名为“数字”的新列来显示统计信息。非常感谢你。
