I'm getting an error that my array value must start with "{". My array I'm trying to create is from a view v_data_type the view consist of only one column with a varchar type.
Can anyone please direct me where the issue in my code is?
Thank you in advance

Answer 1

I don't think you've given us enough information to know for certain what's going wrong. Notably, I have no idea what the tables should look like, either in schema or content. Without that, I can't build a test case in my own DB to debug.
That said, I noticed a couple things, specifically around the lTranstype variable:
You're assigning lTranstype twice. First you SELECT INTO it, and then you immediately assign it to a value unpacked from the p_transtype argument. It's not clear to me what you want in that variable.
When constructing your query later, you include and dt.type = any(' || quote_literall(p_transtype) || '). The problem is that p_transtype is a varchar argument, and you're trying to access it like an array. I suspect you want that to read and dt.type = any(' || quote_literall(lTranstype) || '), but I could be mistaken.
I'm guessing that your type error is coming from that second problem, but it seems like you need to reassess what the different variables in this function are intended for. Good luck.
