+# String_PadRight
+
+`String_PadRight` returns a new string that left-aligns the characters in the `source` string by padding them on the right with a specified `paddingChar` Unicode character, for a specified total length.
+
+```csharp
+String_PadRight (
+	@source NVARCHAR (MAX),
+	@totalWidth INT, 
+	@paddingChar NVARCHAR (1)
+	)
+RETURNS INT
+```
+
+## Parameters
+
+  - **source**: The source string.
+  - **totalWidth**: The number of characters in the resulting string, equal to the number of original characters plus any additional padding characters.
+  - **paddingChar**: A Unicode padding character.
+
+## Returns
+
+ - A new string that is equivalent to the `source` string, but right-aligned and padded on the left with as many paddingChar characters as needed to create a length of `totalWidth`. 
+ - If `totalWidth` is less than the length of the `source` string, the method returns a reference to the existing instance. 
+ - If `totalWidth` is equal to the length of the `source` string, the method returns a new string that is identical to the `source` string.
+
+## Example
+
+```csharp
+SELECT SQLNET::String_PadRight('This is a String.', 20, '.')
+SELECT SQLNET::String_PadRight('This is a String.', 10, '.')
+```
+
+# String_PadRight4k
+
+It is equivalent to `String_PadRight` except no NVARCHAR(MAX) parameters; it can be used when input data will never be over 4000 characters as this function offers better performance.
+
+```csharp
+String_PadRight4k (
+	@source NVARCHAR (4000),
+	@totalWidth INT, 
+	@paddingChar NVARCHAR (1)
+	)
+RETURNS INT
+```
+
+## Example
+
+```csharp
+SELECT SQLNET::String_PadRight4k('This is a String.', 20, '.')
+SELECT SQLNET::String_PadRight4k('This is a String.', 10, '.')
+```
