PERL: Cant use variables in Sybase SQL Driver to MS SQL Server -


i'm trying use dynamically constructed query data ms sql server(2008) in perl.

the sql-string looks this:

$sql = (q/select count(distinct columna) tablea columnb = '$var'/);

when try execute following error message:

dbd::sybase::st execute failed:   server message number=245 severity=16 state=1 line=1 server=hostname   text=conversion failed when converting varchar value '$var' data type tinyint.   @ ./scriptname.pl line 32.

q() literal. need qq() if want $var interpolated.

$sql = qq/select count(distinct columna) tablea columnb = '$var'/;

also, agree comment on sql injection. should use bind variable instead.
