+# ALTER EXTERNAL STREAM (Transact-SQL)
+
+Modifies the definition of an External Stream. Modifying an External Stream that is used by a streaming job in a *Running* state is not allowed. 
+
+
+
+## Syntax
+
+```sql
+  ALTER EXTERNAL STREAM external_stream_name 
+  SET 
+    [DATA_SOURCE] = <data_source_name> 
+    , LOCATION = <location_name> 
+    , EXTERNAL_FILE_FORMAT = <external_file_format_name> 
+    , INPUT_OPTIONS = <input_options> 
+    , OUTPUT_OPTIONS = <output_options> 
+```
+
+
+## Return code values
+
+ALTER EXTERNAL STREAM returns 0 if successful. A non-zero return value indicates failure.
