I have some coding challenges that I'm hoping you can help me out.
I have one file#1 that contains the following sql statement that spans over multiple lines:
Code:
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
First step - Cleanup the file to remove blank lines, comments (#) and convert sql statement to span over 1 line only
Code:
cat file#1 | sed '/^$/d' | sed '/^#/d' | tr '\n\r' ' ' > tmp_file#1
echo >>tmp_file#1
tmp_file#1 now contains:
Code:
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
Challenge#1:
The condition "and b.address is not null" should not be commented out.
I'm thinking the comment part "-- and a.id is not null" should become "/* and a.id is not null */ in order to comment that condition only
How can I easily handle this?
Note: Comments can appear anywhere in the sql statement
Next, I have a second file#2 as follows which I need to replace $$SQL with the sql statement above:
Code:
Existing
...
$$SQL=select count(*) from dual
....
New
...
$$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
....
Code:
sSqlStmt="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"
sed -e "s/\$\$SQL=.*/\$\$SQL=$sSqlStmt/"
Challenge#2:
The "/" and "*" in the sql statment is not producing the desired results by the sed command
I get an error such as "sed function cannot be parsed".
Thank you for any help or insight that you can provide
Everything else seems to be working, but this isn't. Is it the "cat..." that is wrong of the condition? Thanks.

cubrid_prepare
CUBRID_PREPARE(3) 1 CUBRID_PREPARE(3)cubrid_prepare - Prepare a SQL statement for executionSYNOPSIS
resource cubrid_prepare (resource $conn_identifier, string $prepare_stmt, [int $option])
DESCRIPTION
The cubrid_prepare(3) function is a sort of API which represents SQL statements compiled previously to a given connection handle. This
pre-compiled SQL statement will be included in the cubrid_prepare(3).
Accordingly, you can use this statement effectively to execute several times repeatedly or to process long data. Only a single statement
can be used and a parameter may put a question mark (?) to appropriate area in the SQL statement. Add a parameter when you bind a value in
the VALUES clause of INSERT statement or in the WHERE clause. Note that it is allowed to bind a value to a MARK(?) by using the
cubrid_bind(3) function only.
PARAMETERS
o $conn_identifier
-Connection identifier.
o $prepare_stmt
-Prepare query.
o $option
-OID return option CUBRID_INCLUDE_OID.
RETURN VALUES
Request identifier, if process is successful;
FALSE, if process is unsuccessful.
EXAMPLES
Example #1
cubrid_prepare(3) example
<?php
$conn = cubrid_connect("localhost", 33000, "demodb");
$sql = <<<EOD
SELECT g.event_code, e.name
FROM game g
JOIN event e ON g.event_code=e.code
WHERE host_year = ? AND event_code NOT IN (SELECT event_code FROM game WHERE host_year=?) GROUP BY event_code;
EOD;
$req = cubrid_prepare($conn, $sql);
cubrid_bind($req, 1, 2004);
cubrid_bind($req, 2, 2000);
cubrid_execute($req);
$row_num = cubrid_num_rows($req);
printf("There are %d event that exits in 2004 olympic but not in 2000. For example:
", $row_num);
printf("%-15s %s
", "Event_code", "Event_name");
printf("----------------------------
");
$row = cubrid_fetch_assoc($req);
printf("%-15d %s
", $row["event_code"], $row["name"]);
$row = cubrid_fetch_assoc($req);
printf("%-15d %s
", $row["event_code"], $row["name"]);
cubrid_disconnect($conn);
?>
The above example will output:
There are 27 event that exits in 2004 olympic but not in 2000. For example:
Event_code Event_name
