Character arguments in sybase mode must be delimited in one of these ways:
The value can be enclosed in single or double quotes.
The value can be enclosed in one of the following special delimiters (passthrough or tsql0 modes only):
!
%
(
)
*
/
:
<
>
?
\
|
‘
{
}
~
The same character must be used before and after the value.
Do not enclose numeric arguments in quotes or any special
delimiter.
You can specify NULL values in sybase mode in either of these ways:
With either “NULL” or “null” used as the value
With the argument left out of the list (if the procedure contains more than one argument)
