Function signature
Reports signature issues for built-in functions.
The inspection will report a wrong number of arguments, invalid keywords, wrong data types, and other issues.
Example (MySQL):
CREATE TABLE foo (a INT, b INT, c INT)
SELECT IFNULL() FROM foo; -- error
SELECT IFNULL(a) FROM foo; -- error
SELECT IFNULL(a, b) FROM foo; -- OK
SELECT IFNULL(a, b, c) FROM foo; -- error
In MySQL, the IFNULL()
function accepts strictly two arguments. So, only the SELECT IFNULL(a, b) FROM foo;
query is correct.
- By ID
Can be used to locate inspection in e.g. Qodana configuration files, where you can quickly enable or disable it, or adjust its settings.
