This is one example:
Code:
$ cat sql_file.sql
sql Select /*+ use_has(a,b) */ *
    from customer a,
         customer_address b
    where a.id = b.id
    -- and a.id is not null
    and b.address is not null

$ cat sql_file.sql | tr -d '\n' | sed 's/ \{2,\}/ /g' | sed 's/-- //g'
sql Select /*+ use_has(a,b) */ * from customer a, customer_address b where a.id = b.id and a.id is not null and b.address is not null

$ cat file2
$$SQL=select count(*) from dual

$ sql='sql Select /*+ use_has(a,b) */ * from customer a, customer_address b where a.id = b.id and a.id is not null and b.address is not null'

# This just replaces the $$SQL with the contents of the variable($sql) in the file as you requested not the rest of the line.
$ sed "s#\$\$SQL#$sql#g" file2
sql Select /*+ use_has(a,b) */ * from customer a, customer_address b where a.id = b.id and a.id is not null and b.address is not null=select count(*) from dual

execute

EXECUTE(7)                                                         SQL Commands                                                         EXECUTE(7)

NAME

       EXECUTE - execute a prepared statement

SYNOPSIS

       EXECUTE name [ ( parameter [, ...] ) ]

DESCRIPTION

       EXECUTE  is  used  to execute a previously prepared statement. Since prepared statements only exist for the duration of a session, the pre-
       pared statement must have been created by a PREPARE statement executed earlier in the current session.

       If the PREPARE statement that created the statement specified some parameters, a compatible set of parameters must be passed to the EXECUTE
       statement,  or  else an error is raised. Note that (unlike functions) prepared statements are not overloaded based on the type or number of
       their parameters; the name of a prepared statement must be unique within a database session.

       For more information on the creation and usage of prepared statements, see PREPARE [prepare(7)].

PARAMETERS

       name   The name of the prepared statement to execute.

       parameter
              The actual value of a parameter to the prepared statement. This must be an expression yielding a value that is compatible  with  the
              data type of this parameter, as was determined when the prepared statement was created.

OUTPUTS

       The command tag returned by EXECUTE is that of the prepared statement, and not EXECUTE.

EXAMPLES

       Examples are given in the Examples [prepare(7)] section of the PREPARE [prepare(7)] documentation.

COMPATIBILITY

       The  SQL  standard includes an EXECUTE statement, but it is only for use in embedded SQL. This version of the EXECUTE statement also uses a
       somewhat different syntax.
