I am trying to deploy a table called "employee" to different database.
I have create a reload.sql file that contans the structure for this table.

% File:  C:\reload.sql
% Usage:     isql read C:\RELOAD.SQL
% This command file reloads a database that was unloaded using "dbunload".
%CREATE TABLE "DBA"."employee"
(
     "empnum"                  char(15) NOT NULL,
     "empfirstname"            varchar(30) NOT NULL DEFAULT ' ',
     "emplastname"             varchar(30) NOT NULL,
     "address"                 varchar(50) NULL,
     "city"                 char(20) NULL,
     "stateprovcode"           char(2) NULL,
     "phonenum"                char(10) NULL,
     "ssid"                 integer NOT NULL,
     "zippcode"                char(10) NULL,
     PRIMARY KEY ("empnum", "storenum")
)
go
%%%%%%%%%%%%%%%%%       --END of Reload.sql--       %%%%%%%%%%%%%%%%%%
Now when this table doesn't exist in the database and someone executes the following command at the DOS prompt,
isql read c:\reload.sql -c "uid=dba;pwd=xyz;dbn=empdb"
This table gets created without a problem. But if this table already exists then error message that says "item 'employee' already exists"
I want to supress this error message, so that if the table already exists no errors are shown. Can someone help please? Thank you.

If you're running ASA, you'd put the following around your code:

IF (select count(*) from sysobjects where name = 'employee' and type = 'U' ) THEN

CREATE TABLE ... (and the rest of your stuff)

END IF;

If you're running ASE, it's pretty much the same although the syntax will be a little different.  There's no END IF in ASE, I recall.

I am very new to Sybase. Can you please tell me how do I find out whether I am running ASA, or ASE?
Also I need to say, If the table does NOT exist then create table...
Thank you for your help!

ASA is adaptive server anywhere, a small-footprint mobile database.  If you run the query "select @@version" from ISQL in an ASA database it should return a number between 5 and 8.

ASE is adaptive server enterprise, a large-scale RDBMS running on a dedicated database server.  If you run "select @@version" from ISQL in ASE, you should get a number back between 11 and 12.5.

The answer to your second question depends on the answer above.
