I'm using Backand as my backend as a service and I'm trying to find a way to add MySQL full-text search in my App.
Can anyone help me how to do it?
Thanks.
In Backand query you can use any MySQL syntax, so just add input parameter (MyText) as the text to be searched on and use this query:
SELECT * FROM articles
WHERE MATCH (title,body)
AGAINST ('{{MyText}}' WITH QUERY EXPANSION);

I have millions of data in my database table customer. In that, I have the id_token attribute which has value like cus00001 format now I want to change it to ank00001.
What will be the query in rails or mysql to do it for all the data in the database?
You can use simple update query using REPLACE function:
UPDATE `table_name` SET `id_token` = REPLACE(`id_token`, 'ank', 'cus');

I need to display the list of staffs who check into work late in a week. For example the staff checks in at 8.10 when the supposed check in time is at 8.00 AM. I am using datetime for the datetimein and datetimeout field. Can anyone suggest how should I do it?
Well, with no sample tables to work from, it's hard to give a clear answer. But I think what you're looking for is the TIME() function.
This should get you started in the right direction:
SELECT * FROM timeclock_records where TIME(datetimein) > "08:00:00";

how to load mysql table to memorystream with delphi? If possible; making select * from table where ?=? will be very fast. but how?
If you have FireDAC, you could use LocalSQL to write a SQL query against any TDataSet descendent, including an in memory TClientDataSet or FDMemTable.
It's explained in the documentation, and there is a webinar from the author of FireDAC demonstrating how to do it.

Can anyone help me to find out Where does TABLE_LIST structure exist in mysql?
And what are the elements it has?
you are totally right, TABLE_LIST is a structure in MySQL source code. its definition is in "mysql-..*\sql\table.h". i think it is used for parsing and optimizing a query. Actually, i want to learn from it very badly. but it is too complicated for me :)
Are you looking for TABLES in the information_schema database?
