execute

问题 I want to keep a piece of code in a txt file and execute it from my Python script. For example in the txt file there is print("ok") I want my programme to print ok and not print print("ok ") . How can I do this? 回答1: Doing what you want usually is a security risk, but not necessarily so. You'll definitely have to notify the user about potential risk. There is more than one program using execfile() or compile() and exec statement to provide plug-ins system. There is nothing so ugly about it,

问题 I use PDO to connect to my database and I don't know which method is better than the other one for UPDATE, DELETE and INSERT, PDO::exec or PDO::excute. Which should I use? 回答1: Although both methods have a similar naming (exec,execute) they're meant to be used in different scenarios: exec is used to get the number of affected rows. /** * (PHP 5 >= 5.1.0, PECL pdo >= 0.1.0)<br/> * Execute an SQL statement and return the number of affected rows * @link http://php.net/manual/en/pdo.exec.php *

问题 I'm trying to set up a 'master' SSIS Package in SQL Server 2008 to run other 'child' packages. When developing the 'child' packages we have all the packages sitting on disk so we can easily debug them, so we use file connectors during development and can monitor the progress nicely. When we deploy, we deploy the child packages to SSIS on SQL Server and then go through and change all the Execute Package Task's to use a location value of 'SQL Server' and set the PackageName. Once done, we

问题 Is it possible with SQL Server 2008 to execute sql from a variabele in a user defined function? Or is using a stored procedure the only solution? I have an sql statement saved in a variabele @mySqlStatement = "select * from someTable" I want to execute the above statement from within a user defined function, is that possible? 回答1: Yes it is possible, with restrictions. Please read this. Also, be very careful about queries you write that are to be executed in a UDF. Query optimization can be a

问题 I want to further use in the procedure the values I get from a select into execution but can't figure out how to do it. As a test I wrote the following but cannot use the v_1, v_2 or v_3 variables for further logic as they don't take the values 1,2 & 3 as i expected... DROP PROCEDURE IF EXISTS MPT_testing; DELIMITER // CREATE PROCEDURE MPT_testing() READS SQL DATA BEGIN DECLARE v_1 INT; DECLARE v_2 INT; DECLARE v_3 INT; SET @sql=CONCAT('SELECT 1,2 into v_1, v_2'); PREPARE s1 FROM @sql;

问题 This question already has answers here : How to write self-modifying code in x86 assembly (7 answers) Closed 3 years ago . Is there any way to put processor instructions into array, make its memory segment executable and run it as a simple function: int main() { char myarr[13] = {0x90, 0xc3}; (void (*)()) myfunc = (void (*)()) myarr; myfunc(); return 0; } 回答1: On Unix (these days, that means "everything except Windows and some embedded and mainframe stuff you've probably never heard of") you

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 6 years ago . I need to execute a method on a specific date of every year, how could I do this in java? Thanks, Chris. 回答1: In order of preference: The Quartz library (highly recommended). java.util.Timer . Not as powerful as Quartz, but good for simple jobs. The EJB timer service. It's poorly documented, it requires a full
