Hi
Maybe something like:
UPDATE Mytable
Set URL = STUFF(url, charindex('\SQLSafe\',url),LEN('\SQLSafe\'),CASE WHEN
CHARINDEX('_Diff_',url) > 0 THEN '\SQLSafe\Diff\' ELSE '\SQLSafe\Full\'
END )
You may want to try this out with (this may wrap!):
SELECT STUFF(url, charindex('\SQLSafe\',url),LEN('\SQLSafe\'),CASE WHEN
CHARINDEX('_Diff_',url) > 0 THEN '\SQLSafe\Diff\' ELSE '\SQLSafe\Full\'
END )
FROM ( SELECT
'\\10.0.12.110\SQLSafe\COGNOS-DEV\2005-08-29_2017m_51s_Diff_COGNOS-DEV_cm.safe'
AS url
UNION ALL SELECT
'\\10.0.12.110\SQLSafe\TLS-D-AN001\2005-08-29_2041m_11s_Diff_TLS-D-AN001_Northwind.safe'
UNION ALL SELECT
'\\10.0.12.110\SQLSafe\TLS-D-AN001\2005-08-29_2041m_11s_Full_TLS-D-AN001_Northwind.safe'
