我在 postgres 函数中使用这些语句。
Select count(*) into V_check
from employee
where employee_name like 'Raj%';
if V_check == 0
then
update exception set exception_found = 'Raj';
end if;
我收到这个错误:
ERROR: operator does not exist: integer == integer LINE 1: SELECT V_check == 0
最佳答案
您应该使用 = 而不是 ==。
以下是您可以使用的不同比较运算符的列表:
Operator Description
= Equal
<> Not equal. Note: In some versions of SQL this operator may be written as !=
> Greater than
< Less than
>= Greater than or equal
<= Less than or equal
BETWEEN Between an inclusive range
LIKE Search for a pattern
IN To specify multiple possible values for a column
