Operators

Scalars

All of the scalar types generated by PostGraphile (BigFloat, BigInt, BitString, Boolean, CidrAddress, Date, Datetime, Float, Int, InternetAddress, Interval, JSON, KeyValueHash, MacAddress, MacAddress8, String, Time, UUID) have the following operators:

SQL GraphQL Description
IS [NOT] NULL isNull: Boolean Is null (if true is specified) or is not null (if false is specified).
= equalTo: T Equal to the specified value.
<> notEqualTo: T Not equal to the specified value.
IS DISTINCT FROM distinctFrom: T Not equal to the specified value, treating null like an ordinary value.
IS NOT DISTINCT FROM notDistinctFrom: T Equal to the specified value, treating null like an ordinary value.
IN (...) in: [T] Included in the specified list.
NOT IN (...) notIn: [T] Not included in the specified list.
< lessThan: T Less than the specified value.
<= lessThanOrEqualTo: T Less than or equal to the specified value.
> greaterThan: T Greater than the specified value.
>= greaterThanOrEqualTo: T Greater than or equal to the specified value.

where T is the type of the field being filtered.

The only exception is KeyValueHash (hstore) fields, for which no sort operators (<, <=, >, >=) are available.

The following types have additional operators:

InternetAddress (inet) / CidrAddress (cidr)

SQL GraphQL Description
>> contains: InternetAddress Contains the specified internet address.
>>= containsOrEqualTo: InternetAddress Contains or equal to the specified internet address.
<< containedBy: InternetAddress Contained by the specified internet address.
<<= containedByOrEqualTo: InternetAddress Contained by or equal to the specified internet address.
&& containsOrContainedBy: InternetAddress Contains or contained by the specified internet address.

JSON (jsonb)

SQL GraphQL Description
@> contains: JSON Contains the specified JSON.
? containsKey: String Contains the specified key.
?& containsAllKeys [String] Contains all of the specified keys.
?| containsAnyKeys: [String] Contains any of the specified keys.
<@ containedBy: JSON Contained by the specified JSON.

KeyValueHash (hstore)

SQL GraphQL Description
@> contains: KeyValueHash Contains the specified KeyValueHash.
? containsKey: String Contains the specified key.
?& containsAllKeys [String] Contains all of the specified keys.
?| containsAnyKeys: [String] Contains any of the specified keys.
<@ containedBy: KeyValueHash Contained by the specified KeyValueHash.

String

SQL GraphQL Description
LIKE '%...%' includes: String Contains the specified string (case-sensitive).
NOT LIKE '%...%' notIncludes: String Does not contain the specified string (case-sensitive).
ILIKE '%...%' includesInsensitive: String Contains the specified string (case-insensitive).
NOT ILIKE '%...%' notIncludesInsensitive: String Does not contain the specified string (case-insensitive).
LIKE '...%' startsWith: String Starts with the specified string (case-sensitive).
NOT LIKE '...%' notStartsWith: String Does not start with the specified string (case-sensitive).
ILIKE '...%' startsWithInsensitive: String Starts with the specified string (case-insensitive).
NOT ILIKE '...%' notStartsWithInsensitive: String Does not start with the specified string (case-insensitive).
LIKE '%...' endsWith: String Ends with the specified string (case-sensitive).
NOT LIKE '%...' notEndsWith: String Does not end with the specified string (case-sensitive).
ILIKE '%...' endsWithInsensitive: String Ends with the specified string (case-insensitive).
NOT ILIKE '%...' notEndsWithInsensitive: String Does not end with the specified string (case-insensitive).
LIKE '...' like: String Matches the specified pattern (case-sensitive). An underscore (_) matches any single character; a percent sign (%) matches any sequence of zero or more characters.
NOT LIKE '...' notLike: String Does not match the specified pattern (case-sensitive). An underscore (_) matches any single character; a percent sign (%) matches any sequence of zero or more characters.
ILIKE '...' likeInsensitive: String Matches the specified pattern (case-insensitive). An underscore (_) matches any single character; a percent sign (%) matches any sequence of zero or more characters.
NOT ILIKE '...' notLikeInsensitive: String Does not match the specified pattern (case-insensitive). An underscore (_) matches any single character; a percent sign (%) matches any sequence of zero or more characters.

The following operators are also available, but the mapping to SQL is more complex:

GraphQL Description
distinctFromInsensitive Not equal to the specified value, treating null like an ordinary value (case-insensitive).
equalToInsensitive Equal to the specified value (case-insensitive).
greaterThanInsensitive Greater than the specified value (case-insensitive).
greaterThanOrEqualToInsensitive Greater than or equal to the specified value (case-insensitive).
inInsensitive Included in the specified list (case-insensitive).
lessThanInsensitive Less than the specified value (case-insensitive).
lessThanOrEqualToInsensitive Less than or equal to the specified value (case-insensitive).
notDistinctFromInsensitive Equal to the specified value, treating null like an ordinary value (case-insensitive).
notEqualToInsensitive Not equal to the specified value (case-insensitive).
notInInsensitive Not included in the specified list (case-insensitive).

The compiled SQL depends on the underlying PostgreSQL column type. Using case-insensitive operators with text/varchar/char columns will result in calling lower() on the operands. Using case-sensitive operators with citext columns will result in casting the operands to text.

For example, here is how the equalTo/equalToInsensitive operators compile to SQL:

GraphQL operator PostgreSQL column type Compiled SQL
equalTo text/varchar/char <col> = $1
equalTo citext <col>::text = $1::text
equalToInsensitive text/varchar/char lower(<col>) = lower($1)
equalToInsensitive citext <col> = $1

Domains

Domain fields have the same operators as the domain's base type. For example, a domain type declared with create domain ... as text check (...); would have all of the String operators.

Enums

Enum fields have the same operators as scalar fields.

Ranges

Range fields have the same operators as scalar fields, plus the following range operators:

SQL GraphQL Description
@> contains: T Contains the specified range.
@> containsElement: E Contains the specified value.
<@ containedBy: T Contained by the specified range.
&& overlaps T Overlaps the specified range.
<< strictlyLeftOf: T Strictly left of the specified range.
>> strictlyRightOf: T Strictly right of the specified range.
&< notExtendsRightOf: T Does not extend right of the specified range.
&> notExtendsLeftOf: T Does not extend left of the specified range.
-|- adjacentTo: T Adjacent to the specified range.

where T is the type of the range field being filtered and E is the element type of the range.

Arrays

Array fields have the following operators:

SQL GraphQL Description
IS [NOT] NULL isNull: Boolean Is null (if true is specified) or is not null (if false is specified).
= equalTo: [T] Equal to the specified value.
<> notEqualTo: [T] Not equal to the specified value.
IS DISTINCT FROM distinctFrom: [T] Not equal to the specified value, treating null like an ordinary value.
IS NOT DISTINCT FROM notDistinctFrom: [T] Equal to the specified value, treating null like an ordinary value.
< lessThan: [T] Less than the specified value.
<= lessThanOrEqualTo: [T] Less than or equal to the specified value.
> greaterThan: [T] Greater than the specified value.
>= greaterThanOrEqualTo: [T] Greater than or equal to the specified value.
@> contains: [T] Contains the specified list of values.
<@ containedBy: [T] Contained by the specified list of values.
&& overlaps: [T] Overlaps the specified list of values.
= ANY(...) anyEqualTo: T Any array item is equal to the specified value.
<> ANY(...) anyNotEqualTo: T Any array item is not equal to the specified value.
> ANY(...) anyLessThan: T Any array item is less than the specified value.
>= ANY(...) anyLessThanOrEqualTo: T Any array item is less than or equal to the specified value.
< ANY(...) anyGreaterThan: T Any array item is greater than the specified value.
<= ANY(...) anyGreaterThanOrEqualTo: T Any array item is greater than or equal to the specified value.

where T is the item type of the array field being filtered.

Logic

Complex logic can be expressed using the following logical operators:

SQL GraphQL Description
AND and: [T] Checks for all expressions in this list.
OR or: [T] Checks for any expressions in this list.
NOT not: T Negates the expression.
