 ## Arguments   
 
-inputString   
-Is an [expression](../../t-sql/language-elements/expressions-transact-sql.md) of any character type (nvarchar, varchar, nchar, char).
+ *inputString*   
+ Is the string [expression](../../t-sql/language-elements/expressions-transact-sql.md) to be searched. *inputString* can be any character data type (nvarchar, varchar, nchar, char).

+*translations*   
+ Is a string [expression](../../t-sql/language-elements/expressions-transact-sql.md) containing the replacment characters. *translations* must be the same data type and length as *characters*.

 ## Remarks   
 
-`TRANSLATE` function will return an error if characters and translations have different lengths. `TRANSLATE` function should return unchanged input if null vales are provided as characters or replacement arguments. The behavior of the `TRANSLATE` function should be identical to the [REPLACE](../../t-sql/functions/replace-transact-sql.md) function.   
+`TRANSLATE` will return an error if *characters* and *translations* expressions have different lengths. `TRANSLATE` will return NULL if any of the arguements are NULL.  
 
-The behavior of the `TRANSLATE` function is equivalent to using multiple `REPLACE` functions.
