Coonector to SQL

Good morning,
I am new with this.
I’m doing some tests and I would need to know how you make a connection to SQL and retrieve data from multiple tables.
Can I do the conection with asp ? I read that it can do, but i dont know how.
can I do this? some examples?
Thank you very much

You can use render_sql or render_complex_sql and provide any valid sql as parameter. … ral_tables
Above article is for php, but similar concept is implemented in other connectors as well.

Do you mean classic ASP?
There is a version of connector for it, but it lack many latest features.
