Needing help understanding SQL logic re query from work


I'm someone who uses a system that uses SQL, but I'm not a programmer, but would like to learn more about the language at some stage.

We use a 3rd party income management system and it uses SQL, the term stored procedure is used quite a lot by the config consultants and I would just like to learn the logic behind some of the rules within their system.

I do have an example of the query I have and it's in relation to reference numbers re barcoding...

Would someone be able to help, if so, what category should I post too, thanks.

Hi Lewis, the best way to learn SQL like any other language is practice, practice and more practice... Otherwise, it is really hard to remember...

For a start, it helps to understand the JOINS:

SQL statements are used for the purpose of generating queries from the client based program to the database in the database system. It helps the users to perform wide variety of fast data manipulation. So, in general SQL is the most important language that perform function of database server to store and also for editing the data.
When it comes to SQL it is not difficult to learn it. It is not a programming language but a query language. The main objective of creating SQL was to give possibilities to the people to make interesting data from the database. So at the time, someone starts learning SQL it is related to the work across any relational databases.

Hi BabyAqua

It really depends on different people's style of learning @harishgg1. Practice might be what @BabyAqua prefers and you might prefer what described. It's about preference not about correct or incorrect
