☆樱花仙子☆ 提交于 2019-12-23 10:35:22

问题 When trying to identify erroneous data (often needing manual review and removal), I'd like an easy way of seeing hidden characters, such as TAB, Space, Carriage return and Line feed. Is there a built-in way for this? In a similar question here on stackoverflow, regarding Oracle, a DUMP(fieldname) function was suggested, but I don't know if that woud make things easier even if a corresponding function would exist in SQL Server, since I need to see the Characters in their context. The best idea

How Oracle uses statistics data

问题 In previous question I got comment about Oracle statistics: Oracle doesn't know that 50M is greater than the number of rows. Sure, it has statistics, but they could be old and wrong - and Oracle would never allow itself to deliver an incorrect result only because the statistics are wrong I was pretty sure that Oracle relies on statistics when preparing query execution plan. Before version 10 it was recommended to refresh statistics from time to time and from 10g Oracle gathers statistics

Export to excel from SQL Server 2000 using Query Analyzer code

What's the easiest way to export data to excel from SQL Server 2000. I want to do this from commands I can type into query analyzer. I want the column names to appear in row 1. Manual copy and paste is the only way to do exactly what you're asking. Query Analyzer can include the column names when you copy the results, but I think you may have to enable that somewhere in the options first (it's been a while since I used it). Other alternatives are: Write your own script or program to convert a result set into a .CSV or .XLS file Use a DTS package to export to Excel Use bcp.exe (but it doesn't

问题 This question already has answers here : Closed 7 years ago .
