If You want to execute multiple query same time then create sring with all statement and execute it.
Like:

string strQuery = " Insert into tbl values(1,1);Update tbl set fld=value where id=id;update tbl2 set fld=value where id=id;";

Yes, it can be; Microsoft Access supports Transactions [^]and they work quite well.

Even so, if possible, use SQL Server Express. It's much more powerful than Access.

Solution 1

Yes, the queries need to seperated by semi-colon ";"

eg:

C#

string query = "insert into table1(x,y,z); update table2 set a = 23;"
OledbCommand cmd = new OledbCommand(query, connection);
.
.
.
cmd.ExecuteNonQuery();
