Greetings,
i want to know, if its better to specify the columns in selecting in a table rather than using a select * in a table, will i have faster searching or retrieval of records if i will specify the columns i need in a query?
what is the disadvantage of using select * in a table and advantage of selecting the specified columns in a table,
Please help me on this, I really need an concrete answer to my question, it will help me a lot in constructing my code, also i want my query to have good retrieval and connection to my database,
Thank you..
