Question

当我在C＃中使用缓存sql查询时，我收到错误：

SQLtext1 = "SELECT top 10 * FROM dbo.DAPPLICATIONSTAT where TIMESTAMP = '2015-02-01 00:00:00'"

我想使用带有日期时间过滤器的where子句。

我正在使用InterSystems.Data.CacheClient.dll来执行查询。

错误消息：

[SQLCODE: <-4>:<A term expected, beginning with one of the following: identifier, constant, aggregate, %ALPHAUP, %EXACT, %MVR, %SQLSTRING, %SQLUPPER, %STRING, %UPPER, $$, :, +, -, (, NOT, EXISTS, or FOR>] 
[Cache Error: <<SYNTAX>errdone+2^%qaqqt>] [Details: <Prepare>] 
[%msg: < SQL ERROR #4: A term expected, beginning with either of: (, NOT, EXISTS, or FOR^SELECT top :%qpar(1) * FROM dbo . DAPPLICATIONSTAT where TIMESTAMP>

Answer 1

我认为你保留了TIMESTAMP字样，所以你有这个错误尝试使用此SQL查询，其中将字段名称TIMESTAMP置于可变配额中

SELECT top 10 * FROM dbo.DAPPLICATIONSTAT where "TIMESTAMP" = '2015-02-01 00:00:00'

具有datetime的系统间缓存C＃查询
