The forum will experience an outage sometime between February 10 at 7:00pm EST and February 12 at 11:59 EST for installation of security updates. The actual time and duration of the outage are unknown but attempts will be made to minimize the downtime. We apologize for any inconvenience.

When using SQL Anywhere 12 ISQL with "Text" checked in Tools - Options - SQL Anywhere - Style, BINARY values can be truncated according to the length of the column name.

At first I thought this was expected behavior, but after being misled about a value, I no longer hold that opinion; 'tis a bug, not a feature :)

Rather than try to describe the rather funky "rules", the following example will demonstrate:

SELECT 0x30313233343536373839 AS a,
       a AS bbbbbbbbbbbbb,
       a AS cccccccccccccc,
       a AS ddddddddddddddddddddd, 
       a AS eeeeeeeeeeeeeeeeeeeeee, 
       a AS fffffffffffffffffffffffffff

a            bbbbbbbbbbbbb cccccccccccccc ddddddddddddddddddddd eeeeeeeeeeeeeeeeeeeeee fffffffffffffffffffffffffff 
------------ ------------- -------------- --------------------- ---------------------- --------------------------- 
0x3031323334 0x30313233343 0x303132333435 0x3031323334353637383 0x30313233343536373839 0x30313233343536373839

It looks like the algorithm for the output width is 2 for the 0x + sizeof(item). The size of the binary value is 10 bytes.

A work-around is to cast the hexadecimal string to a type twice as long (20 instead of default 10). Here's an example.

SELECT CAST( 0x30313233343536373839 as BINARY(20) ) AS a,
       a AS bbbbbbbbbbbbb,
       a AS cccccccccccccc,
       a AS ddddddddddddddddddddd,
       a AS eeeeeeeeeeeeeeeeeeeeee,
       a AS fffffffffffffffffffffffffff;

CAST ( 0x30313233343536373839 AS BINARY ( 10 ) ) seems to make it work as well, so perhaps there's something deeper going on here :)

Running from the command line like this?

dbisql -c dba,sql read c:\temp\bin.sql

It doesn't for me. Perhaps it depends on the build.

My mistake... ignore my comment.
