Each imported CSV would be imported into its own table. We are not concerned about data-type inferencing. The CSV vary in structure and layout, and all of them have many many columns, yet we are only concerned with a few of them: street addresses and zipcodes.

Find index of last occurrence of a sub-string using T-SQL

阅读更多关于 Find index of last occurrence of a sub-string using T-SQL

Is there a straightforward way of finding the index of the last occurrence of a string using SQL? I am using SQL Server 2000 right now.

A little googling revealed this - Function To Retrieve Last Index - but that does not work if you pass in a "text" column expression. Other solutions found elsewhere work only so long as the text you are searching for is 1 character long. I will probably have to cook a function up. If I do so, I will post it here so you folks can look at it and maybe make use of. gbn

阅读更多关于 Regular Expressions in SQL Server servers?

问题 Is it possible to make efficient queries that use the complete regular expression feature set. If not Microsoft really should consider that feature. 回答1: For SQL Server 2000 (and any other 32 bit edition of SQL Server), there is xp_pcre, which introduces Perl compatible regular expressions as a set of extended stored procedures.
