simultaneous row iteration [计] 同时行迭代
When a for statement is executed, a cursor is implicitly declared such that for each iteration of the for loop, the next row is the result set if fetched.
在执行for语句时,游标被隐式声明,这样对于FOR循环的每一次迭代,取回的下一行就是结果集。
You will recall that DataTables execute an implicit loop over their rows, and the var attribute indicates the value of the current row during the iteration.
您将再次调用 DataTables 对各表行执行隐式循环,var 属性指示迭代过程中的当前行。
On each iteration, db2_result gets the value for each field within the row.
在每次迭代中,db 2 _ result将获取行内每个字段的值。
