Ask a question about WINFORM, the database is mysql,
1 For example, a picture in the picturebox control in my program
I want to insert the product name, product model, and product quantity into a record in the database
Can it be achieved with a sql statement? I heard that it is not possible,
Is there any source code that can be referred to? This is the problem of writing the picture to the database

1. Yes, as long as you save Bytes, note that the header must have 0x pointer

2. Reading is easier, many controls can be directly bound
