Question

I have code numbers as the following sequential:

1
1.1
1.2
1.3
.
.
.
1.1.1
1.1.2
.
.
.
2

And so..

I want a method to that parses the children based on some input. For example, if the input is 1 then it will retrieve all it’s children, and if the input is 1.1 it will retrieve all of it’s children, etc.

How can I do something like that?

Notes:

• This data is stored in one table in Informix database.
• The code numbers are strings.

Answer 1

Code

var list = new List<string>();
var children = list.Where(s => s.StartsWith(inputString));

DB

DECLARE @p1 varchar(100)
SET @p1 = '1.1%'
SELECT * FROM tbl WHERE tbl.col LIKE @p1
