I must generate a database and all database objects.
For that I have some sql files and a .bat file (Windows).
In Oracle I use the commands define and prompt and take from the .bat the input parameters. In SQL Server I use the system database master where I create a table and write there the parameters (database name for example).
Is it possible in a db2sql file to receive an input parameter?
For example in the .bat i have something like that

set Database_Name=%1

How can I use this information in a db2 sql file?
I cannot use the sql server solutions because I don't have system databases.
Thanks for your help.

Sounds like a job for db2look.

Unfortunately db2 doesn't have anything like that for the sql file. Although for DBNAME you can use db2set DB2DBDFT=MYDB and just do CONNECT with no options.

Finally I used two .bat files.
I have the parameters user, server, password and database name.
I connect to the idle instance (force to use connect reset because either I ewas connected to a database, I don't know which one?)
In the second .bat file I create the database and then I run the sql files with the other objects (tablespaces, tables etc)
The only solution is to create the database in the bat and not in the sql file.
Thanks.
