Javascript array contains. >>> df4. This system function will benefit from a range index. If it evaluates to 'true' and if the specified search value is an object, the command checks for a partial match (the search object is a subset of one of the objects). In string_to_array, if the delimiter parameter is NULL, each character in the input string will become a separate element in the resulting array.If the delimiter is an empty string, then the entire input string is returned as a one-element array. Array comparisons compare the array contents element-by-element, using the default B-tree comparison function for the element data type. If there are more than one element in the same row of an array column, the first element is at position 1. Each element in the output ARRAY is the value of the single column of a row in the table.. The syntax goes like this: Where expression is the JSON string expression, and pathis the property you want to extract from that expression.
