The syntax for using readpast locking is:
{select | update | delete} ...
from tablename [holdlock | noholdlock]
[readpast] [shared]
...
readtext [[database.]owner.]table_name.column_name text_pointer offset size [holdlock | noholdlock] [shared] [readpast] ...
writetext [[database.]owner.]table_name.column_name text_pointer [readpast] [with log] data
