Hello!
I use next way for call sp:
$sp=mssql_init("sp");
mssql_bind($sp,"stringdata",'',SQL_VARCHAR);
mssql_execute...

when param 'stringdata' passed to stored procedure, we
got null instead empty string.
I don't specify is_null paramether for mssql_bind function.
by default this paramether is false.

This bug is still present in PHP5.1 and in WinXP.

All empty strings are always converted to NULL by "mssql_bind", although $is_null argument is set to false.

This bug is very annoying, as empty string is normal and valid value, and is different from NULL value. I have non-NULL-able columns, and I cannot insert empty strings because of this stupid bug.
