How to query a column of array type-CodePudding

I have a table conditions with a trigger_values column that is of type array and I want to query this table on the trigger_values and fetch the matching records. For example, suppose my conditions table has 3 rows:

<Condition id: 1, trigger_values: [1, 2, 3]>,
<Condition id: 2, trigger_values: [2, 4]>,
<Condition id: 3, trigger_values: [3, 5, 7]>

and I have the query parameter 3, I should get conditions 1 and 3 as their trigger_values columns contain 3. Basically, I want something like this:

Condition.where('trigger_values CONTAINS ?', query_value)

Any help would be appreciated. Thanks

CodePudding user response：

You should use the IN operator:

Condition.where('trigger_values IN (?)', query_value)

Found the solution:

Condition.where("'#{query_value}' = ANY(trigger_values)")

I needed to use ANY command.
