Hello guys,

can someone give an advice what is the proper way how to write into mysql DB?

I have two columns (already created manually in mysql DB)

If i try to write some data in these two columns in the first round it is fine

i have no problem. But if I try to write another data into these columns (where is already written data from the first round) it doesn’t work? Why? Should I use another node? Like insert etc.

Can you give me a hint please?

Thank you

Jiri

You may violate some table constraints. What the error did you get?
