Find a specific substring using Transact-SQL

Question

I need to pull a specific substring from a string of the form:

foo=abc;bar=def;baz=ghi

For example, how would I get the value of \"bar\" from t

Answer 1

This can achieve in simple way

DECLARE  @str VARCHAR(30)

DECLARE  @start INT

SET @str='foo=abc;bar=def;baz=ghi'

SET @start=CHARINDEX('bar',@str)

PRINT SUBSTRING(@str,@start,3)
