在PROC SQL查询中,若用户需要指定titles和footnotes,则须将TITLE和FOOTNOTE语句放在PROC SQL语句之前或者放在介于PROC SQL语句和SELECT语句之间。例如: 1procsql outobs=15;2title'Current Bonus Information';3title2 ‘EmployeewithSalaries>$75,000’;4selectempid label='Employee ID',5jobcode label='Job Code',...
这一特性使得我们可以将逻辑表达式嵌套在算数表达式中,更进一步地说,这其实可以看成指示函数(Indicator function)的一种形式。 💡 计算 BMI2 变量的表达式中,使用了 CASE 表达式的运算结果作为算数运算符 / 的两个操作数,不难发现 CASE 表达式的计算结果也可以作为操作数在其他表达式中使用。 SQL 表达式大部分用法...

In the second part of the HAVING expression, we are asking SQL to compute a summary function (getting the MAX value) on that column NUMRES, which is already a SUMMARY function result – hence, they are nested. So, how do we get around this to select the largest provider? One way to...

身份注册声明:openGauss 中存在一个系统表 pg_proc,这个表存放了所有函数的基本元信息,相当于函数的“户口本”,只有在其中可以查到的函数,才可以在 SQL 语句中进行调用,才有“数据库函数”的身份。常见的注册方式有:builtin、升级脚本、CREATE FUNCTION 语句、EXTENSION。
