c# SQL 查询错误，格式为 dd.MM.yyyy

Question

Using format from Norway dd.MM.yyyy in my computer I've got syntax error when I try to get data from MS Access database. Query:

query = "SELECT * FROM DateTable WHERE StartDate BETWEEN #18.03.2016# AND #19.03.2016#"

If I change to other formats (my computer settings and in query) then everything is ok.

PD: I have the same problem using INSERT. Thanks

Answer 1

I would strongly suggest using ISO date format like YYYY-MM-dd for both INSERT/UPDATE and SELECT operations. This will format be understood correctly both by database and .net. The format of date is just a cosmetic issue about displaying. When you have a correct date object you can show it as you wish.

Answer 2

不知道您的代码，但如果您坚持创建 SQL 字符串，则必须将日期值的字符串表达式格式化为如下所示：

query = "SELECT * FROM DateTable WHERE StartDate BETWEEN #2016/03/18# AND #2016/03/19#"
