MySQL: Trying a "simple" INSERT INTO with BLOB Data

I'm trying to just insert an XLSX file into a MySQL large blob field.

However, it all seems to depend on the LOAD_FILE command which isn't working either in MySQL 8.



This command just gives me a null.

So, then I guess it's not unexpected that the INSERT statement that uses this LOAD_FILE() would also fail with null.



The INSERT statement says "1 Row(s) affected." but nothing was inserted. Still Null (0 bytes).

I've tried with other files like zips and such with the same result.

So, how the heck to you get simple BLOB data into a BLOB field?

Thanks!

I took a quick look at MySQL's LOAD_FILE and LOAD DATA features and everything I read (on the web) mentioned that you'd use it for text files. So they aren't going to work for XLSX files anyway. Although that still doesn't clearly explain why you get nothing.

I was just trying to easily load a blob file into MySQL to do a sanity check with Connection Pooling in SpringBoot that wasn't working as expected with another DB vendor.
I finally (just) got the blob inserted by using a prepared statement in code.
I was just hoping I could drag the XLSX to a field and have it paste. Nope!

Thanks again! Appreciate your reply.
