Function

TrimRight

Implements

ICheckItem

IDefaultItem

IElement

Remarks

The RTRIM function removes spaces and other whitespace characters from the end of a string, leaving leading whitespace intact. This is useful for removing padding while preserving indentation or other leading formatting.

Examples

Remove trailing whitespace from product names before display:

var schema = manager.LoadSchema("catalog");
var products = schema["products"];

var query = new Query()
    .Select([ products["id"], new Expression("clean_name", new TrimRight(products["name"])) ])
    .From(products);

var results = manager.Retrieve(query);

Use the typed Column constructor when working with a pre-resolved column variable:

var schema = manager.LoadSchema("catalog");
var products = schema["products"];
Column nameColumn = products["name"];

var query = new Query()
    .Select([ products["id"], new Expression("clean_name", new TrimRight(nameColumn)) ])
    .From(products);

var results = manager.Retrieve(query);

Right-trim a hard-coded string literal to remove trailing whitespace:

var query = new Query()
    .Select([ new Expression("trimmed", new TrimRight("hello   ")) ]);

var results = manager.Retrieve(query);
