当我尝试将表名作为这样的参数时出现语法错误:
[WebGet]
public List<callersW> GetCallersByCallerIdF(string callerid)
{
testCDREntities1 context = this.CurrentDataSource;
List<callersW> result = context.Database.SqlQuery<callersW>("SELECT CallerId,CalledID,Created, " +
" Answered,Destroyed,DisconnectionCode,RTP_Caller_G107MOS,RTP_Caller_LostPackets, " +
" RTP_Caller_MaxRfc3550Jitter,RTP_Caller_MeanRfc3550Jitter,RTP_Called_G107MOS, " +
" RTP_Called_LostPackets,RTP_Called_MaxRfc3550Jitter,RTP_Called_MeanRfc3550Jitter FROM TestTable where CallerId = '"+ callerid +"'").ToList();
return result;
}
但如果我将其内联,那么它可以正常工作:
An exception of type 'System.Data.SqlClient.SqlException' occurred in System.Data.Entity.dll but was not handled in user code
Additional information: Incorrect syntax near 'TestTable'.
这是错误:
photo = PhotoImage(...)
label = Label(image=photo)
label.image = photo # keep a reference!
label.pack()
答案 0 :(得分:0)
您不必引用表名 - 在您的示例中,表名在第二个示例中指定为TestTable
,但在第一个示例中它出现在'TestTable'
。表名不应该用引号括起来。
如果您使用保留关键字作为表名,则应使用反引号括起表名,例如:
`TestTable`
请注意,单引号字符不。
