#3949394
I would like to know the base object that is used in the synonyms, so there is a column called base_object_name:
- The table is use is (
```
SELECT base_object_name
FROM sys.synonyms
```
)
Is there someone who is able to sepereate the value in the columns?
I would like the value [db].[dbo].
in seperate column.
Need some help?

Easy. Use PARSENAME():

SELECT base_object_name
      ,CONCAT(QUOTENAME(PARSENAME(base_object_name, 3)), '.', QUOTENAME(PARSENAME(base_object_name, 2)))
FROM sys.synonyms;

That not really the solution, but I have something but not complete:

 SELECT DISTINCT [name] AS SYN_NAME,
  LEFT (REPLACE(REPLACE(base_object_name ,'[',''),']',''),
    CHARINDEX('.', REPLACE(REPLACE(base_object_name ,'[',''),']',''))-1) AS DBNM,
  (LEFT (REPLACE(REPLACE(base_object_name ,'[',''),']',''),
    CHARINDEX('.', REPLACE(REPLACE(base_object_name ,'[',''),']',''))-1)) AS DBID,
  RIGHT (REPLACE(REPLACE(base_object_name ,'[',''),']',''),
    CHARINDEX('.', reverse(REPLACE(REPLACE(base_object_name ,'[',''),']','')))-1) AS objectname
FROM sys.synonyms

The only think that needs CHANGE is the middle part DBID must be my SCHEMANAME 🙂

Please explain why it's "not really the solution".

SELECT base_object_name
      ,DBName = PARSENAME(base_object_name, 3)
      ,SchemaName = PARSENAME(base_object_name, 2)
      ,ObjectName = PARSENAME(base_object_name, 1)
FROM sys.synonyms;
