Well, you do, if you want to compare it more than once, since $? is overwritten every time you execute a program or statement.

This is an ideal place to use a case statement though:

Code:
case "$?" in
0) # statement zero code
   # statement zero code
   ;;
1) # statement one code
   # statement one code
   ;;
2) # statement two code
   # statement two code
   ;;
*) # All other cases
   # All other cases
   ;;
esac

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)
