Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

Do placeholders work in SET clause of UPDATE query for column datatype of UNSIGNED INT in ASE 15.7+?

After much time wasting I found -- with DBI 1.625, DBD::Sybase 1.14, & ASE 15.7 -- that ...

By way of crude, untested but representative code ...

# SQL. create table pqr ( x numeric(9,0) not null , y unsigned int not null ) insert into pqr values( 0 , 0 ) # Perl $n = 1; # Works. $dbh->do( q/UPDATE pqr SET x = ?/ , undef , $n ); $n = 2; # Fails; $dbh->do( q/UPDATE pqr SET y = ?/ , undef , $n ); $n = 3; # works (same as %s, this is all string in the end). $dbh->do( sprintf q/UPDATE pqr SET y = %d/ , $n );
