Question Run SQL queries in DB2 and output to file

Hi,

I new to Unix and scripting. Following is my requirement. Can someone tell me whether its possible or not. Also please let me know how to proceed further if this is possible.

List of queries are stored in a file. For example, I have to run a query like this:
Select * from &XYZ where field1=&ABC

where &XYZ is the file name that needs to be taken from another file TEMP1. And &XYZ is the DB2 file name. We need to connect to DB2 database from Unix system.
where &ABC is the entry parameter which needs to be given

Finally the result needs to be stored in a temporary file.

Is is possible to execute a query with these conditions.

Database used is DB2
and System is AIX UNIX

db2_stmt_error - Returns a string containing the SQLSTATE returned by an SQL statement

SYNOPSIS
string db2_stmt_error ([resource $stmt]) DESCRIPTION
Returns a string containing the SQLSTATE value returned by an SQL statement. If you do not pass a statement resource as an argument to db2_stmt_error(3), the driver returns the SQLSTATE value associated with the last attempt to return a statement resource, for example, from db2_prepare(3) or db2_exec(3). To learn what the SQLSTATE value means, you can issue the following command at a DB2 Command Line Processor prompt: db2 '? $sqlstate- value'. You can also call db2_stmt_errormsg(3) to retrieve an explicit error message and the associated SQLCODE value. PARAMETERS
o $stmt - A valid statement resource. RETURN VALUES
Returns a string containing an SQLSTATE value. SEE ALSO
db2_conn_error(3), db2_conn_errormsg(3), db2_stmt_errormsg(3). PHP Documentation Group DB2_STMT_ERROR(3)
