如何使用MS SQL Server Management Studio删除SQL数据库表中的前导空白空间

Question

I imported an Excel sheet with countries into a database table. 我将带有国家/地区的Excel工作表导入到数据库表中。

Unfortunately all rows have some leading empty space. 不幸的是，所有行都有一些空的空间。

So, how can I delete these empty spaces? 那么，我该如何删除这些空格呢？

Answer 1

This will remove leading and trailing spaces 这将删除前导和尾随空格

Update tablename set fieldName = ltrim(rtrim(fieldName));

some versions of SQL Support 某些版本的SQL支持

Update tablename set fieldName = trim(fieldName);

If you just want to remove leading 如果你只是想删除领先

update tablename set fieldName = LTRIM(fieldName);
