![]() ![]() This is an approximation of what I want in behaviour : SELECT * FROM foo WHERE CONCAT(bar::text, baz::text, qux::text) ~ ?īut not ideal for reasons you can guess (and requires special handling/escaping depending on the regex pattern). Each subclause provides a subquery that produces a. It's not clear to me whether Composite Type Comparisons would support "~" :Ĭomposite type comparisons are allowed when the operator is =,, or >=, or has semantics similar to one of these.īesides which, I'm even more lost as to how I'd construct multiple columns into a record on the left side, and 1 regex pattern into a record on the right of the operator "~". To specify common table expressions, use a WITH clause that has one or more comma-separated subclauses. Postgres complains that the right-hand side must be an array, when I've tried. returns TRUE if ANY of the sub query values meet the condition. The left-hand expression is evaluated and compared to each element of the array using the given operator, which must yield a Boolean result. ![]() The ANY operator: returns a Boolean value as a result. ALL (array) expression operator ALL ( array expression ) The right-hand side is a parenthesized expression, which must yield an array value. IN vs ANY operator in PostgreSQL-postgresql. Row constructor comparisons are allowed when the operator is =,, or >=.īesides which, I'd have to somehow explode 1 bound regex pattern into a row on the right-hand side. The ANY operator allows you to perform a comparison between a single column value and a range of other values. "row_constructor operator row_constructor" seems closer to what I need, but ~ is not available : All queries combined using a UNION, INTERSECT or EXCEPT operator must. how many instances in the cluster, etc.). When an application is vulnerable to SQL injection and the results of the query. I pored over Row and Array Comparisons, and Functions and Operators, and more, but docs are light on examples.įeels like I've got all the pieces, but can't connect 'em. This ensures that the PostgreSQL Operator is not a single-point of failure for the availability of any of the PostgreSQL clusters that it manages, as the PostgreSQL Operator is only maintaining the definitions of what should be in the cluster (e.g. The following illustrates the syntax of the ANY operator: expresion operator ANY (subquery) In this syntax: The subquery must return exactly one column. How can I elegantly do the opposite - pick out rows where 1+ columns match one regex ? SELECT * FROM foo WHERE ANY (bar, baz, qux) ~ ? The PostgreSQL ANY operator compares a value to a set of values returned by a subquery. This automation adds a level of complexity to the container-based architecture and stateful applications, such as a database. Where ? is an array of any 1+ regex patterns for column "bar" to match. ![]() Postgres conveniently allows : SELECT * FROM foo WHERE bar ~ ANY (?) ![]()
