SPLIT

Splits a string around a java-style regular expression.

Syntax

SPLIT ( 'string', 'regexp' [, index] )  

Arguments

'string'

Is an expression of any character type (i.e. nvarchar, varchar, nchar or char).

'regexp'

Is a Java-style regular expression of any character type that is used around 'string'.

[index]

Optional index of result you want to return. If no index value is specified, regexp results are returned as a string separated by single character '|' (pipe).

Example

Splits values from column "s" using different regular expressions and returns results using result index:

select split([s], '[AB]',  0) as a
     , split([s], '[ABC]', 1) as b
     , split([s], '[ABC]', 2) as c
from 
(
  select 'abaAbbbBccC' as s union all
  select 'aaaAbbbBcCc'      union all
  select 'oneAtwoBthreeC'
) as dat

Result:

a     b     c
----- ----- ----
aba   bbb   cc
aaa   bbb   c
one   two   three
