C# C.NPOCO。错误:“尝试加入时,&.”附近的语法不正确
我有一个存储过程,由NPOCO在下一个linq查询后创建:C# C.NPOCO。错误:“尝试加入时,&.”附近的语法不正确,c#,sql,sql-server,stored-procedures,npoco,C#,Sql,Sql Server,Stored Procedures,Npoco,我有一个存储过程,由NPOCO在下一个linq查询后创建: var componentVarians = _repository.Get().Include(x => x.Component) .Where(x => x.IsActive == true & x.ServingTypeId == servingType & x
var componentVarians = _repository.Get().Include(x => x.Component)
.Where(x => x.IsActive == true &
x.ServingTypeId == servingType &
x.Component.IsActive == true &
x.Component.BotanicalName.ToLower().Contains(value.ToLower())).ToList();
exec sp_executesql N'SELECT [CVD].[Id] as [Id], [CVD].[Name] as [Name], [CVD].[Sku] as [Sku], [CVD].[ServingTypeId] as [ServingTypeId], [CVD].[Price] as [Price], [CVD].[IsActive] as [IsActive], [CD].[Id] as [Component__Id], [CD].[BotanicalName] as [Component__BotanicalName], [CD].[HebrewName] as [Component__HebrewName], [CD].[PinYanName] as [Component__PinYanName], [CD].[IsActive] as [Component__IsActive], [CD].[CreatedDate] as [Component__CreatedDate] FROM [ComponentVariant] [CVD]

执行此存储过程后,我得到一个错误:
“&”附近的语法不正确
将查询更改为双精度查询&&
var componentVarians = _repository.Get().Include(x => x.Component)
.Where(x => x.IsActive == true &&
x.ServingTypeId == servingType &&
x.Component.IsActive == true &&
x.Component.BotanicalName.ToLower().Contains(value.ToLower())).ToList();
将查询更改为双精度查询&&
var componentVarians = _repository.Get().Include(x => x.Component)
.Where(x => x.IsActive == true &&
x.ServingTypeId == servingType &&
x.Component.IsActive == true &&
x.Component.BotanicalName.ToLower().Contains(value.ToLower())).ToList();
修改Linq表达式:
var componentVarians = _repository.Get().Include(x => x.Component)
.Where(x => x.IsActive &&
x.ServingTypeId == servingType &&
x.Component.IsActive &&
x.Component.BotanicalName.ToLower().Contains(value.ToLower())).ToList();
bool类型的属性不使用x.IsActive==true或x.IsActive==false。
如果要在错误时进行筛选,请使用评估!x、 i激活修改Linq表达式:
var componentVarians = _repository.Get().Include(x => x.Component)
.Where(x => x.IsActive &&
x.ServingTypeId == servingType &&
x.Component.IsActive &&
x.Component.BotanicalName.ToLower().Contains(value.ToLower())).ToList();
bool类型的属性不使用x.IsActive==true或x.IsActive==false。
如果要在错误时进行筛选,请使用评估!x、 IsActive在Linq中,其中expresion put&&而不仅仅是一个&。在T-SQL中,@LasseVågsætherKarlsen和In the Linq Where expresion put&&而不仅仅是一个&。在T-SQL中,@LasseVågsætherKarlsen和它如何对linq to objects起作用,但由于这是linq to SQL,因此无法正确解析转换,我理解。布尔操作数的&运算符在C中仍然是一个逻辑运算符,我假设实体框架仍会使用它,在生成的SQL中将其转换为&符号没有意义,但我错了。它适用于linq to对象,但由于这是linq to SQL,因此无法正确解析转换。我理解。布尔操作数的&运算符在C中仍然是一个逻辑运算符,我假设Entity Framework仍会使用它,在生成的SQL中将其转换为&符号是没有意义的,但我错了。
