Functions and Operators

Warning:
CockroachDB v22.1 is no longer supported. For more details, see the Release Support Policy.

CockroachDB supports the following SQL functions and operators for use in scalar expressions.

Tip:
In the built-in SQL shell, use \hf [function] to get inline help about a specific function.

Special syntax forms

The following syntax forms are recognized for compatibility with the SQL standard and PostgreSQL, but are equivalent to regular built-in functions:

CURRENT_CATALOG current_catalog()
COLLATION FOR pg_collation_for()
CURRENT_DATE current_date()
CURRENT_ROLE current_user()
CURRENT_SCHEMA current_schema()
CURRENT_TIMESTAMP current_timestamp()

Function volatility

A function's volatility is a promise to the optimizer about the behavior of the function.

Type Description Examples
Volatile The function can modify the state of the database and is not guaranteed to return the same results given the same arguments in any context. random, crdb_internal.force_error, nextval, now
Stable The function is guaranteed to return the same results given the same arguments whenever it is evaluated within the same statement. The optimizer can optimize multiple calls of the function to a single call. current_timestamp, current_date
Immutable The function does not depend on configuration settings and is guaranteed to return the same results given the same arguments in any context. The optimizer can pre-evaluate the function when a query calls it with constant arguments. log, from_json
Leakproof The function does not depend on configuration settings and is guaranteed to return the same results given the same arguments in any context. In addition, no information about the arguments is conveyed except via the return value. Any function that might throw an error depending on the values of its arguments is not leakproof. Leakproof is strictly stronger than Immutable. Integer comparison

Conditional and function-like operators

The following table lists the operators that look like built-in functions but have special evaluation rules:

Operator Description
ANNOTATE_TYPE(...) Explicitly Typed Expression
ARRAY(...) Conversion of Subquery Results to An Array
ARRAY[...] Conversion of Scalar Expressions to An Array
CAST(...) Type Cast
COALESCE(...) First non-NULL expression with Short Circuit
EXISTS(...) Existence Test on the Result of Subqueries
IF(...) Conditional Evaluation
IFNULL(...) Alias for COALESCE restricted to two operands
NULLIF(...) Return NULL conditionally
ROW(...) Tuple Constructor

Aggregate functions

For examples showing how to use aggregate functions, see the SELECT clause documentation.

Note:

Non-commutative aggregate functions are sensitive to the order in which the rows are processed in the surrounding SELECT clause. To specify the order in which input rows are processed, you can add an ORDER BY clause within the function argument list. For examples, see the SELECT clause documentation.

Operators

The following table lists all CockroachDB operators from highest to lowest precedence, i.e., the order in which they will be evaluated within a statement. Operators with the same precedence are left associative. This means that those operators are grouped together starting from the left and moving right.

3 - Unary minus unary (prefix)
~ Bitwise not unary (prefix)
4 ^ Exponentiation binary
5 * Multiplication binary
/ Division binary
// Floor division binary
% Modulo binary
6 + Addition binary
- Subtraction binary
7 << Bitwise left-shift binary
>> Bitwise right-shift binary
&& Overlaps binary
8 & Bitwise AND binary
9 # Bitwise XOR binary
10 | Bitwise OR binary
11 || Concatenation binary
< ANY, SOME, ALL Multi-valued "less than" comparison binary
> ANY, SOME, ALL Multi-valued "greater than" comparison binary
= ANY, SOME, ALL Multi-valued "equal" comparison binary

>= ANY, SOME, ALL Multi-valued "greater than or equal" comparison binary
<> ANY / != ANY, <> SOME / != SOME, <> ALL / != ALL Multi-valued "not equal" comparison binary
[NOT] LIKE ANY, [NOT] LIKE SOME, [NOT] LIKE ALL Multi-valued LIKE comparison binary

>@ Tests whether the left JSONB field is contained by the right JSONB field. binary
#> Access a JSONB field at the specified path, returning a JSONB value. binary
#>> Access a JSONB field at the specified path, returning a string. binary
? Does the key or element string exist within the JSONB value? binary
?& Do all the key or element strings exist within the JSONB value? binary
?| Do any of the key or element strings exist within the JSONB value? binary
12 [NOT] BETWEEN Value is [not] within the range specified binary
[NOT] BETWEEN SYMMETRIC Like [NOT] BETWEEN, but in non-sorted order. For example, whereas a BETWEEN b AND c means b <= a <= c, a BETWEEN SYMMETRIC b AND c means (b <= a <= c) OR (c <= a <= b). binary
[NOT] IN Value is [not] in the set of values specified binary
[NOT] LIKE Matches [or not] LIKE expression, case sensitive binary
[NOT] ILIKE Matches [or not] LIKE expression, case insensitive binary
[NOT] SIMILAR Matches [or not] SIMILAR TO regular expression binary
~ Matches regular expression, case sensitive binary

!=, <> Not equal binary
14 IS [DISTINCT FROM] Equal, considering NULL as value binary
IS NOT [DISTINCT FROM] a IS NOT b equivalent to NOT (a IS b) binary
ISNULL, IS UNKNOWN , NOTNULL, IS NOT UNKNOWN Equivalent to IS NULL / IS NOT NULL unary (postfix)
IS NAN, IS NOT NAN Comparison with the floating-point NaN value unary (postfix)
IS OF(...) Type predicate unary (postfix)
