尝试使用以下代码:
Integer[][] myarray ={ {1}, {1,2}, {1,2,3,4,5} }; String test = "Insert Arrays"; stopWatch.start(test); myDBconn.setAutoCommit(false); Statement stmt = myDBconn.createStatement(); stmt = myDBconn.createStatement(); stmt.execute("TRUNCATE TABLE Schema.Table1"); //在我们的数组数组上运行循环 for (int i = 0 ; i < (myarray.length); i++) { int curr_length = myarray[i].length; String arrayFunction = "ARRAY ("; for (int j = 0; j < (curr_length); j++){ arrayFunction = arrayFunction.concat(myarr[i][j].toString()) ; //如果不是最后一个元素,请添加逗号 if (j < (curr_length - 1)){ arrayFunction = arrayFunction.concat(", ") ; } } arrayFunction = arrayFunction + ")" ; //您可以看到arrayFunction,如下所示 //数组(...,....,,) String insCMD = "INSERT INTO Table1 (id, Value) " + " VALUES (" + i + ", " + arrayFunction + " ) "; System.out.println(insCMD); int affectedRows = stmt.executeUpdate(insCMD); System.out.println("Loop round " + i + ", last affected row count " + affectedRows); } myDBconn.commit(); stmt.close(); stmt = null;
输出结果
运行Select语句时上述程序的输出:
ID Value 0 1 1 1, 2 2 1, 2, 3, 4, 5
