Question

I am having a very strange problem inserting values into my mysql database, using php, so i was running a test, the simplest of the simple insert; the following doesnt work:

<?php
include("config.php"); // put the *FULL* path to the file.

mysql_query("INSERT INTO 'lms'.'test2' ('trn') VALUES ('17')");

?>

However the following works:(Note the difference in single quotes)

<?php
include("config.php"); // put the *FULL* path to the file.

mysql_query("INSERT INTO `lms`.`test2` (`trn`) VALUES ('17')");

?>

I really can’t see what the problem is could I get sum assistance please

Answer 1

You don’t need to encapsulate tables within a query unless they have space or they are reserved words.

INSERT INTO 'lms'.'test2' ('trn') VALUES ('17')
// This makes no real sense to the db. It should be:
INSERT INTO lms.test2 (trn) VALUES ('17')

If the column trn accepts numbers, it really should be:

INSERT INTO lms.test2 (trn) VALUES (17)

With MySQL, you can use the tilted quote character to encapsulate names, but not strings. To enter a string in the query you will have to use normal quotes like '.

You can to this:

select `someTable`.`someColumn` from `someTable`

but not this:

select someTable.someColumn from someTable where myName=`Tommy`;

The correct use would be:

select someTable.someColumn from someTable where myName='Tommy';
