数据库执行SELECT查询语句时,各子句的书写先后顺序是:()
A: HAVING,WHERE,GROUPBY
B: GROUPBY,HAVING,WHERE
C: WHERE,GROUPBY,HAVING
D: WHERE,HAVING,GROUPBY
A: HAVING,WHERE,GROUPBY
B: GROUPBY,HAVING,WHERE
C: WHERE,GROUPBY,HAVING
D: WHERE,HAVING,GROUPBY
举一反三
- where子句、groupby子句、having子句在select语句中的顺序是() A: having子句、groupby子句、where子句 B: groupby子句、having子句、where子句 C: groupby子句、where子句、having子句 D: where子句、groupby子句、having子句
- SQL语法中,用查询语句时,以下执行顺序正确的是? A: from、where、groupby、select、distinct*、having、orderby B: from、where、groupby、having、select、distinct*、orderby C: from、groupby、where、select、distinct*、having、orderby D: from、where、groupby、select、distinct*、orderby、having
- 在数据库查询语句中用于排序的子句是哪个?() A: GROUPBY B: ORDERBY C: WHERE D: HAVING
- 查询语句中用于分组子句后的语句是哪个?() A: GROUPBY B: HAVING C: WHERE D: ORDERBY
- 1聚集函数能否直接使用在SELECT子句,HAVING子句,WHERE子句,GROUPBY子句中?
