insert records from one table to another - php

Question

Hi I am trying to add records from one table to another, once i have added a 'user' record, the table that is being selected contains rows of available security options, and the table that is being inserted to is the child table for the user, detailing security options.
I cam across this code in an earlier post, which i am sure works nicely, however i am trying to modify it so that the values from statement, includes two parts, one from the select query and one which is the key from the master record.#
This is the original code I found from this site:
INSERT INTO def (catid, title, page, publish)
SELECT catid, title, 'page','yes' from `abc`
And this is what I am trying to do with it:
$sql = "INSERT INTO Link_UserSecurity (UserFk, ModuleFk) values ('".$keys["UserPk"]."', SELECT ModulePk from Global_Modules)";
CustomQuery($sql);
And this is the error I am getting:
INSERT INTO Link_UserSecurity (UserFk, ModuleFk) values ('4', SELECT
ModulePk from Global_Modules)
See screenshot for further detail
Obviously I am not concating the from statement properly, but would appreciate any help?

Answer 1

You can insert the $keys["UserPk"] variable as if it were a constant in the SQL:
$sql = "INSERT INTO Link_UserSecurity (UserFk, ModuleFk) SELECT '{$keys["UserPk"]}', ModulePk from Global_Modules";
Do note that $keys["UserPk"] must be escaped before adding it into the query. In PDO, it would look like this:
$keys["UserPk"] = $pdo->quote($keys["UserPk"]);
$sql = "INSERT INTO Link_UserSecurity (UserFk, ModuleFk) SELECT '{$keys["UserPk"]}', ModulePk from Global_Modules";

Answer 2

Could be a problem related to the double quotes sequence
"INSERT INTO Link_UserSecurity (UserFk, ModuleFk)
values ('". $keys['UserPk']. "', SELECT ModulePk from Global_Modules)";
but you could use also a select insert
"INSERT INTO Link_UserSecurity (UserFk, ModuleFk)
SELECT '" . $keys['UserPk']. "' , ModulePk from Global_Modules)";

Adding only new and unique records from one table to another. Limiting is a good idea to prevent it from timeout. It can be run several times until all the records copied.
First, select the latest record ID from the table to be copied:
SET #lastcopied =
(SELECT
IF(MAX(a.exp_inotech_id)>0, MAX(a.exp_inotech_id), 0) AS lastcopied
FROM
kll_export_to a
WHERE exp_tezgah = 'A2015-0056');
Then, select and add the records to the destination table:
INSERT INTO kll_export_to
(SELECT * FROM
kll_export_from f
GROUP BY f.exp_inotech_id
HAVING COUNT(f.exp_inotech_id) = 1 AND exp_tezgah = 'A2015-0056' AND f.exp_inotech_id > #lastcopied
ORDER BY exp_inotech_id
LIMIT 1000);
