可以使用exec函数执行SQL语句来实现: % 定义SQL插入语句sql=sprintf('INSERT INTO your_table (column1, column2, ...) VALUES (%s, %s, ...)',...'?','?',...);% 准备SQL语句curs=exec(conn,sql);% 遍历表格数据forrow=1:size(T,1)% 将数据写入数据库fetch(curs,[T{row,1},T{row,2},....
Unicode text, specified as a character vector, string scalar, M-element cell array of character vectors, or M-element string array. M is the number of specified text positions in position. The function overwrites pixels with the value of text. If you specify a single string or character vec...
从 数据库中读取数据到matlab有三种数据类型(默认为元胞类型cellarray),分别为元胞类型(cellarray),数字型 (numeric),结构型(structure)。可以在链接数据库之前通过setdbprefs函数来进行设置。如果数据库文件中全部是数值型数据时 最好采用numeric型的数据,这样可以使得读取速度大幅提高,特别是在大型数据读取时非常明显。
