I have persons in my database with their attended trainings but as time goes by, each of them will add some trainings again so i need to add it after that name.
I have table with columns id, firstname and training but that's my problem, inserting after a selected name
Sample
Insert into table (firstname, training) values ("Zarie", "Technical Writing Course") after a selected row where id = (select id where firstname="Zarie");
Thank you.
When you adding row to mysql table it goes to the end of table or on free primary key id. You can't change this when you inserting data. You can change order only when you selecting data:
SELECT * FROM table WHERE name = 'name' ORDER BY id DESC, firstname ASC
SELECT id, firstname FROM table WHERE name != 'Zimbo' ORDER BY firstname ASC

I'm wanting to create a sql select statement that will grab rows if a given value is in a comma separated list in one of the columns of the database table.
Example Table...
id | courses
1 | 5, 8, 15, 19
I want to do something like this
$course_num = 5;
$sql = "SELECT * FROM courses WHERE $course_num IS IN courses";
1.) I don't think the "IS IN courses" part is legit. How can I do this?
2.) For my code above, I would want to return the row because of the "5" in courses, not because of the "15". So, if $course_num = 9 no rows should be returned.
Thanks for your help.
By adding comma in searched occurrence
SELECT *
FROM courses
WHERE concat(', ',course,',') like '%, 5,%'

I have a database which has a field containing some comma separated values like 1,8,3,54,5,19,9..... I want to select only those rows where 2 doesn't exists.
The query below is used for finding all fields containing the number 2 in the attachedCompanyIDs column. However, I want to find all rows where that number doesn't exist, but I don't know how to use find_in_set in this case. Can any one please help me?
SELECT name FROM company
WHERE orderID = 1 AND FIND_IN_SET(2, attachedCompanyIDs);
SELECT name FROM company
WHERE orderID = 1 AND NOT FIND_IN_SET(2, attachedCompanyIDs);
or
SELECT name FROM company
WHERE orderID = 1 AND FIND_IN_SET(2, attachedCompanyIDs) = 0;

I want to add a common column in all tables in a database
For example:
I want to insert the column TENANT_ID in all tables in database
How can i do that.
You use the ALTER TABLE SQL command as in:
ALTER TABLE table_name
ADD column_name datatype
If you have multiple tables you'll need to apply this to each table in succession.
More here: http://www.w3schools.com/sql/sql_alter.asp
yes you can add it
if you have list of table in array
$column_name = 'TENANT_ID';
$size = '';
foreach($all_table_name as $each_table_name) {
mysql_query("ALTER TABLE {$each_table_name} ADD {$column_name} VARBINARY({$size})");
}
above code i just skilton you have to set accourding to your code.
