某一日发现这么如下这么一个错误  --> maximum number of expressions in a list is 1000 原因:因为SQL语句中用到了IN字句,而IN中的元素个数超过了1000个而导致. 方法: 1.在程序中将一个IN改成多个IN: 2.把IN List 改成一个SELECT语句,把IN List中的元素放到一个Nested Table中 3.控制in中的查询数量为1000个(使用top 1000配合order by createDate desc可省不少麻烦)…

使用POI导出xls文件,由于数据过多,导致导出xls报错如下: The maximum number of cell styles was exceeded. You can define up to 4000 styles in a .xls workbook 原因: 代码中创建 HSSFCellStyle cellStyle = hssfWorkbook.createCellStyle(); 次数过多,导致报错. 解决方法: 把创建HSSFCellStyle对象放在循环之外,或者放在全局,…
