contains

I have an array of strings. I want to check if a particular string is present in the array. DECLARE TYPE v_array IS TABLE OF VARCHAR2(200); ais_array v_array; BEGIN ais_array := ('Lb1','Lb2','Lb3','Lb613'); IF 'Lb1' IN ais_array THEN dbms_output.put_line('found'); END IF; END; The IN operator is not working. I tried doing a select * on the type and then using IN but that didn't work either. Any suggestions? Egor Skriptunoff Try member of condition: IF 'Lb1' member of ais_array THEN dbms_output.put_line('found'); END IF; Oracle introduced several set operators for working with collections in

I'm constructing a linq query that will check is a string in the DB contains any of the strings in a list of strings. Something like. query = query.Where(x => x.tags .Contains(--any of the items in my list of strings--)); I'd also like to know how many of the items in the list were matched. Any help would be appreciated. Update: I should have mentioned that tags is a string not a list. And I am adding on a couple more wheres that are not related to tags before the query actually runs. This is running against entity framework. EDIT: This answer assumed that tags was a collection of strings...

Is there a reason that they decided not to add the contains method (for Path) in Android? I'm wanting to know what points I have in a Path and hoped it was easier than seen here: How can I tell if a closed path contains a given point? Would it be better for me to create an ArrayList and add the integers into the array? (I only check the points once in a control statement) Ie. if(myPath.contains(x,y) So far my options are: Using a Region Using an ArrayList Extending the Class Your suggestion I'm just looking for the most efficient way I should go about this I came up against this same problem a

Is there an xpath way to find a node that has a given attribute whose value contains a given string? For example I have an xml document and want to find a node where the address attribute contains the string Downing , so that I could find the following node: <person name="blair" address="10 Downing St. London"/> select="//*[contains(@address,'Downing')]" 来源： https://stackoverflow.com/questions/614797/xpath-find-a-node-that-has-a-given-attribute-whose-value-contains-a-string

Is there a method for checking if a table contains a value ? I have my own (naive) function, but I was wondering if something "official" exists for that ? Or something more efficient... function table.contains(table, element) for _, value in pairs(table) do if value == element then return true end end return false end By the way, the main reason I'm using this functions is to use tables as sets, ie with no duplicate elements. Is there something else I could use ? interjay You can put the values as the table's keys. For example: function addToSet(set, key) set[key] = true end function

public class PricePublicModel { public PricePublicModel() { } public int PriceGroupID { get; set; } public double Size { get; set; } public double Size2 { get; set; } public int[] PrintType { get; set; } public double[] Price { get; set; } } List<PricePublicModel> pricePublicList = new List<PricePublicModel>(); How to check if element of pricePublicList contains certain value. To be more precise, I want to check if there exists pricePublicModel.Size == 200 ? Also, if this element exists, how to know which one it is? EDIT If Dictionary is more suitable for this then I could use Dictionary, but

I am receiving a "wildcard query expansion resulted in too many terms" error when executing a query similar to the following: SELECT * FROM table_a WHERE contains(clob_field, '%a%') > 0; Does anyone know a workaround/solution to this problem? According to this , you may need to increase the wildcard_maxterms parameter, or take further steps. See the link for details (I'm not an expert in Oracle Text though). 来源： https://stackoverflow.com/questions/2554054/wildcard-query-expansion-resulted-in-too-many-terms
