Operators

With the SQL Assessment API, you can use different kinds of operators to make your assessment even more precise.

In This Section

Operator	Arguments	Description
not	(x)	Logical not.
and	(a..*)	Logical AND. Returns `false` without arguments.
or	(a..*)	Logical OR. Returns `true` without arguments.

Operator	Arguments	Description
indexof	(str_a, str_b)	Finds a zero-based index of the first str_b occurrence in the string str_a. Case-sensitive.
iindexof	(str_a, str_b)	Finds a zero-based index of the first str_b occurrence in the string str_a. Case-insensitive.
startswith	(str_a, str_b)	Returns `true` if the string str_a starts with the string str_b. Case-sensitive.
istartswith	(str_a, str_b)	Returns `true` if the string str_a starts with the string str_b. Case-insensitive.
endswith	(str_a, str_b)	Returns `true` if the string str_a ends with the string str_b. Case-sensitive.
iendswith	(str_a, str_b)	Returns `true` if the string str_a ends with the string str_b. Case-insensitive.

Operator	Arguments	Description
ceiling	x	Rounds x to the nearest greater or equal value.
floor	x	Rounds x to the nearest lower or equal value.
max	(a, b)	Returns maximum of a and b.
min	(a, b)	Returns minimum of a and b.
mul	(a..*)	Arithmetic multiplication.
div	(a, b)	Arithmetic division of a by b.
mod	(a, b)	Arithmetic remainder of a divided by b.
add	(a..*)	Arithmetic sum.
sub	(a, b)	Arithmetic difference of a and b.
bitand	(a..*)	Bitwise AND.
bitor	(a..*)	Bitwise OR.
bitxor	(a..*)	Bitwise XOR.

Operator	Arguments	Description
intersect	(a, b)	Sets intersection of a and b arguments. Case-sensitive.
in	(a, b)	Checks if the argument a was found in b. The b argument represents a collection. Case-sensitive.
iin	(a, b)	Checks if the argument a was found in b. The b argument represents a collection. Case-insensitive.

Operator	Synonyms	Arguments	Description
lt	less	(a, b)	Checks if the argument a is less than the argument b.
gt	greater	(a, b)	Checks if the argument a is greater than the argument b.
eq	equal	(a, b)	Checks if both arguments are equal. Case-sensitive.
ieq		(a, b)	Checks if both arguments are equal. Case-insensitive.
ge	greaterequal	(a, b)	Checks if the argument a is greater than or equals to the argument b.
le	lessequal	(a, b)	Checks if the argument a is less than or equals to the argument b.
ne	notequal	(a, b)	Checks if the argument a is not equal to the argument b. Case-sensitive.
ine		(a, b)	Checks if the argument a is not equal to the argument b. Case-insensitive.
match		(a, b)	Regular expression match. The second argument is treated as a regular expression. Case-sensitive.
imatch		(a, b)	Regular expression match. The second argument is treated as a regular expression. Case-insensitive.
interval		(a,v₁,t₁,...,v_n,t_n,d)	Finds the first t_i that is greater than or equal to a and returns the corresponding v_i. Returns d if all t are less than a.
