# RTRIM (Transact-SQL)
[!INCLUDE [sql-asdb-asdbmi-asa-pdw](../../includes/applies-to-version/sql-asdb-asdbmi-asa-pdw.md)]

  Returns a character string after truncating all trailing spaces.  
  
 ![Topic link icon](../../database-engine/configure-windows/media/topic-link.gif "Topic link icon") [Transact-SQL Syntax Conventions](../../t-sql/language-elements/transact-sql-syntax-conventions-transact-sql.md)  
  
## Syntax  
  
```syntaxsql
RTRIM ( character_expression )  
```  
  
[!INCLUDE[sql-server-tsql-previous-offline-documentation](../../includes/sql-server-tsql-previous-offline-documentation.md)]

## Arguments
 *character_expression*  
 Is an [expression](../../t-sql/language-elements/expressions-transact-sql.md) of character data. *character_expression* can be a constant, variable, or column of either character or binary data.  
  
 *character_expression* must be of a data type that is implicitly convertible to **varchar**. Otherwise, use [CAST](../../t-sql/functions/cast-and-convert-transact-sql.md) to explicitly convert *character_expression*.  
  
## Return Types  
 **varchar** or **nvarchar**  
  
## Examples  
  
### A. Simple Example  
 The following example takes a string of characters that has spaces at the end of the sentence, and returns the text without the spaces at the end of the sentence.  
  
```sql  
SELECT RTRIM('Removes trailing spaces.   ');  
```  
  
 [!INCLUDE[ssResult](../../includes/ssresult-md.md)]  
  
  `Removes trailing spaces.`  
  
### B: Simple Example  
 The following example demonstrates how to use `RTRIM` to remove trailing spaces. This time there is another string concatenated to the first string to show that the spaces are gone.  
  
```sql  
SELECT RTRIM('Four spaces are after the period in this sentence.    ') + 'Next string.';  
```  
  
 [!INCLUDE[ssResult](../../includes/ssresult-md.md)]  
  
`Four spaces are after the period in this sentence.Next string.`  

### C. Using RTRIM with a variable  
 The following example demonstrates how to use `RTRIM` to remove trailing spaces from a character variable.  
  
```sql  
DECLARE @string_to_trim VARCHAR(60);  
SET @string_to_trim = 'Four spaces are after the period in this sentence.    ';  
SELECT @string_to_trim + ' Next string.';  
SELECT RTRIM(@string_to_trim) + ' Next string.';  
GO  
```  
  
 [!INCLUDE[ssResult](../../includes/ssresult-md.md)]  
  
```
Four spaces are after the period in this sentence.     Next string.

Four spaces are after the period in this sentence. Next string.
```
