It turned out that many entries in the table 1 and table 2 had string_field column with NULL values. I thought that JOIN would keep records with NULL values because NULL is equal to NULL, isn’t it? Then I tried: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 SELECTNULL=NULL It ...
When you compare nonnull expressions, the result is TRUE if the left operand is not equal to the right operand; otherwise, the result is FALSE. If either or both operands are NULL, see the topic SET ANSI_NULLS (Transact-SQL). Transact-SQL syntax conventions Syntax syntaxsql Copy ...
We can use the NOT EQUAL operator with the GROUP BY clause to group the results by the values that are not equal to the specified text value.The aggregate functions such as COUNT(), MAX(), MIN(), SUM(), and AVG() are frequently used with the GROUP BY statement.Example...

DSL 脚本与 SQL 相比可以更加的「柔软」。DSL 中声明 DIVIDE(SUM(spent), COUNT(spent)) 表达式可以被正确的转换为 SUM(spent) / COUNT(spent)而不是直接报错;判断值相当的操作声明 EQUAL 还是 EQUALS 也都是被允许的。基于 SQL 想要达成一样的效果就要困难很多。(**Misunderstanding Knowledge Evidence**) ...
