I need some help, in the databse, my first column (the primary key) I have a name, so it's set to VARCHAR(45) and the rest of my columns are numbers, wich is also set to VARCHAR(45).
When i translate the data from my c# to MySQL, i Reads:
"System.Windows.Forms.TextBox, Text: 58.8"
This is what is says in the columns, insted of just 58.8, it says: "System.Windows.Forms.TextBox, Text:" in front of it.
Why is that?
nothing esle to say . all is into this video .
think you
even if u choose eld = 1000 they will show you that the data r changed !!
I get : data type mismatch in critieria expresson. Any tips? Don't understand the error, when it works fine for adding (saving) users.
Very useful information! Thank you for your effort and hard work!
1 question: What if I want to update just 1 field from DB, for example only the First Name and leave everything the same ?
How to connect Database ?
thank for the video
This kind of tables contain a column that is marked as "Primary Key". Primary Key means that same data cannot repeat and null data cannot be inserted. In this table, I think "Eid" is primary key. Therefore, it is logical to depend to this column. However, if the column you use is not Primary Key or Unique Key, then you must add "AND tablename = ' " + tablenameValue + " ' " after "this.Eid_txt.Text +" code.
Any idea how instead of not just depending on if it's the same eid but on another column as well at the same time?
