Escape characters

What should one pass as a field value into a table in the insert
statement if the value contained a percentage symbol (%) or the
asterisk symbol (*), since both of these have special wildcard
meanings. What if I want to pass the special meanings and pass them as
literals? Is there any escape character that I must use? I am using
ADO.NET v1.1 of the framework with VB.NET. The database is Microsoft
SQL Server 2000.
Hi
In as search condition there is the ESCAPE clause that allows you to specify
the escape character, you can also specify a literal character by using
square brackets.
See the topic "Pattern Matching in Search Conditions" in Books online.
When you are inserting the characters there should not be a need to escape
them e.g
CREATE TABLE #fred ( col1 varchar(10) )
INSERT INTO #fred values ( '%_*' )
INSERT INTO #fred select '%_*'
select * from #fred
col1
%_*
%_*

quotes. % has a meaning in the context of LIKE, not in INSERT.
