Question

I have a sql table and I have a column which includes data such as: B757-34-11-00-I-1, A300-223100-0503-1 etc.

A300-223100-0503-1 -> 223100-0503-1
B757-34-11-00-I-1 -> 34-11-00-I-1

How can i do that with regex? I need two kinds of solutions: sql and C#. how can I do that with sql query in SQL and C#

i need drop charater as far as “-” may be dropping more than 5 characters or less than? i need also drop “-“

Answer 1

In SQL:

SUBSTRING(col, PATINDEX('%-%', col) + 1)

in C#:

val.Substring(val.IndexOf('-') + 1)

This requirement is so simple, there is no need for regexes (and SQL Server does not natively support them anyway if you do not add this via a stored procedure implemented in .net).
