I am trying to find a way to insert multiple rows into MySQL at one time - I was reading about something like
 INSERT INTO table (a,b) VALUES (1,2), (2,3), (3,4);
but can anyone give me an example of how to write the code, for example I have a memorylog array
(public MemoryLog memorylog;) and I have the number of entries that it will have to return
(for (int i = 0; (i < Program.MainForm.myBus.numberofsurveys); i++))
then I assign values. but I am not sure how to  build the query and fill it

Does anyone know?

fill string variable with sequentially added insert command and pass variable for executing:

String sSQL;

sSQL = "";
for (int i = 0; (i < Program.MainForm.myBus.numberofsurveys); i++)
{
   sSQL = sSQL + "INSERT INTO table (a,b) VALUES (" + valueAasStr+ ", " + valueBasStr + ");";
}
//execute sSQL - same as one INSERT

Open in new window

1. You should use a stringbuilder class object instead of regular string concatenation.
2. Your posted syntax is correct.  Your loop would append a series of comma-separated data tuples, each enclosed within a parenthesis pair, "(" and ")"

The  "INSERT INTO table (a,b) VALUES" string is only needed once, so it should not appear within the loop.
