More details, please. Like script behaviour, execution logs, undesired results, error messages, what have you. It's difficult to base an analysis on thin air... and we have nothing.



Might be worthwhile to clarify some wording in your request: You're using "export" in various contexts which may become quite confusing if not sharply discriminated. "[Ee]xport" is
- a keyword in bash (and other shells) for the "export" attribute to variables and functions "marking it for export to child processes" (man bash).
- a term in ORACLE (and other DB) context to create a backup / copy of a database and/or its tables and meta data. Fortunately, the respective SQL command is "exp".
- a variable in your code snippet above.
- used in your description for an action that doesn't necessarily comply with what you're showing in your snippet.


Now to your script. You don't show it, but I guess you should have received an SQL error message telling you it doesn't understand the "export" command. Well, it doesn't as that is a shell command that sql can't interpret and thus ignores or, worse, crashes on. The latter may be the reason why there is only one table in the spool file. The second table should be in the file if the wrong command were simply ignored.

You'd need to define the various file variables upfront, and then switch the SPOOLing from one to the next in sql.
BTW, the Export variable will be empty in above script as the space after the = will assign it such, and then bash will try to interpret / run the result of the sqlplus "command substitution", and error out on that (presumably).

asadmin-export(1AS)						   User Commands					       asadmin-export(1AS)

NAME
asadmin-export, export - marks a variable name for automatic export to the environment of subsequent commands in multimode SYNOPSIS
export [ name=value [ name=value]*] Marks a variable name for automatic export to the environment of subsequent commands. All subsequent commands use the variable name values as specified; unless you unset them or exit multimode. If only the variable name is specified, the current value of that variable name is displayed. If the export command is used without any arguments, a list of all the exported variables and their values is displayed. Exported shell environment variables set prior to invoking the asadmin utility are imported automatically and set as exported variables within asadmin. Unexported environment variables cannot be read by the asadmin utility. OPERANDS
name=value variable name and value for automatic export to the environment to be used by subsequent commands. Example 1: Using export to list the environment variables asadmin> export AS_ADMIN_HOST=bluestar AS_ADMIN_PORT=8000 AS_ADMIN_USER=admin AS_ADMIN_PASSWORD=password asadmin> export AS_ADMIN_PREFIX=server1.jms-service asadmin> export //to list the environment variables that are set AS_ADMIN_HOST=bluestar AS_ADMIN_PORT=8000 AS_ADMIN_USER=admin AS_ADMIN_PASSWORD=******** AS_ADMIN_PREFIX=server1.jms-service Where: the export command lists the environment variables that are set. In this case, the environment variables have been set to: the host is bluestar, the port is 8000, the administrator user is admin with an associated password, and the prefix is server1.jms-service. EXIT STATUS
0 command executed successfully 1 error in executing the command asadmin-unset(1AS), asadmin-multimode(1AS) J2EE 1.4 SDK March 2004 asadmin-export(1AS)
