Postgresql any example

You want to use ALL, not ANY. From the fine manual: 9. 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 result of ANY is true if any true result is obtained. PostgreSQL wildcard LIKE for any of a list. Aside from building aggregate functions, it has some other common day uses.

A protip by cs3b about performance and postgresql. ALL (subquery) the expression evaluates to true if a value is not equal to any value returned by the subquery. In case the subquery returns no row, then the ALL operator always evaluates to true.

Let’s use the film table from the sample database for the demonstration. Also, if the right-hand array contains any null elements and no true comparison result is obtaine the result of ANY will be null, not false (again, assuming a strict comparison operator).

The FOR NO KEY UPDATE, FOR SHARE and FOR KEY SHARE variants, as well as the NOWAIT and SKIP LOCKED options, do not appear in the standard. I have a simple list of ~words. I want to find any row in my table that has any of those words.

LIKE pattern matching always covers the entire string. Functions allow database reuse as other applications can interact directly with your stored procedures instead of a middle-tier or duplicating code. While creating table, for each column, you specify a data type, i. What is an example of a sequence which.
