sql - Regex pattern inside REPLACE function - 


select replace('abctemplate1', 'template\d+', ''); select replace('abc_xyztemplate21', 'template\d+', '');

i trying remove part template followed n digits string. result should be

abc abc_xyz

however replace not able read regex. using sqlserver 2008. doing wrong here? suggestions?

select substring('abctemplate1', 1, charindex('template','abctemplate1')-1)

or 

select substring('abc_xyztemplate21',1,patindex('%template[0-9]%','abc_xyztemplate21')-1)

more generally,

select substring(column_name,1,patindex('%template[0-9]%',column_name)-1) sometable patindex('%template[0-9]%',column_name) > 0

you can use substring charindex or patindex if pattern being looked fixed.
