out of the 4 potential hazards that you have listed
since the query is executed only on a table with 0.25 million records, I just encounter the 4th hazard which is taking real long time.
When it initially took such a long time, I though I might be receiving ' Long transaction aborted '. But didn't.
Considering the alternative of programmatically deleting is a fine idea without filling the logs.

cubrid_num_rows
CUBRID_NUM_ROWS(3) 1 CUBRID_NUM_ROWS(3)
cubrid_num_rows - Get the number of rows in the result set
SYNOPSIS
int cubrid_num_rows (resource $result)
DESCRIPTION
The cubrid_num_rows(3) function is used to get the number of rows from the query result. You can use it only when the query executed is a
select statement. When you want to know such value for INSERT, UPDATE, or DELETE query, you have to use the cubrid_affected_rows(3) func-
tion.
Note: The cubrid_num_rows(3) function can only be used for synchronous query; it returns 0 when it is used for asynchronous query.
PARAMETERS
o $result
-$result comes from a call to cubrid_execute(3), cubrid_query(3) and cubrid_prepare(3)
RETURN VALUES
Number of rows, when process is successful.
0 when the query was done in async mode.
-1, if SQL statement is not SELECT.
FALSE when process is unsuccessful.
EXAMPLES
Example #1
cubrid_num_rows(3) example
<?php
$conn = cubrid_connect("localhost", 33000, "demodb", "dba");
$req = cubrid_execute($conn, "SELECT * FROM code");
$row_num = cubrid_num_rows($req);
$col_num = cubrid_num_cols($req);
printf("Row Num: %d
Column Num: %d
", $row_num, $col_num);
cubrid_disconnect($conn);
?>
The above example will output:
Row Num: 6
Column Num: 2
