Microsoft.Data.SqlClient.SqlException (0x80131904)：“，”附近的语法不正确

Question

我认为这可能是语法错误，但我找不到。

这是完整的错误：

这是我怀疑的代码行

在 FincredixAppBigBrotherWebApi.Application.Sucursales.Queries.GetAllSucursales.GetAllSucursalesHandler.Handle(GetAllSucursalesQuery 请求，CancellationToken 取消令牌）在 C:\Users\alozano\source\repos\FincredixAppBigBrotherWebApi\FincredixAppBigBrotherWebApi.Application\Sucursales\Queries\GetAllSucursales\GetAllSucursalesHandler.cs:line 28

这是第 28 行：

public async Task<List<SucursalViewModel>> Handle(GetAllSucursalesQuery request, CancellationToken cancellationToken)
{
    var response = this._mapper.Map<List<SucursalViewModel>>(await this._fincredixAppDbContext.SpAppFcxSucursalSel.FromSqlRaw(
                    $@"{SpConstants.SpAppFcxSucursalSel}
                    @pnClaSucursal = { request.ClaSucursal },
                    @psDescripcion = { request.Descripcion },
                    @pnClaSucursalPadre = { request.ClaSucursalPadre },
                    @pnIncBajaLogica = { request.BajaLogica }")
                    .AsNoTracking().ToListAsync(cancellationToken));
    return response;
}

我已经看到很多与这个问题非常相似的问题，但不正确的语法是“？”或 ')' 或 'from' 或 '/' 等。我的是 ','

Answer 1

不应该是：

 $@"{SpConstants.SpAppFcxSucursalSel}
                    @pnClaSucursal = '{request.ClaSucursal}',
                    @psDescripcion = '{request.Descripcion}',
                    @pnClaSucursalPadre = '{request.ClaSucursalPadre}',
                    @pnIncBajaLogica = '{request.BajaLogica}'")
