ABP入门教程(六)ABP支持DataTable

首先要添加一个辅助类MsSqlHelper 百度一下就有, 在 .netCore3.1以上需要用Microsoft.Data.SqlClient替代Systemt.Data.SqlClient
然后在RepositoryBase里面添加常用的查询方法, 如下

using Abp.Domain.Entities;
using Abp.Domain.Repositories;
using Abp.EntityFrameworkCore;
using Abp.EntityFrameworkCore.Repositories;
using Microsoft.Data.SqlClient;
using System.Data;

namespace Xxxxx.EntityFrameworkCore.Repositories
{
    /// 

    /// Base class for custom repositories of the application.
    /// 
    /// Entity type
    /// Primary key type of the entity
    public abstract class XxxxxRepositoryBase : EfCoreRepositoryBase
        where TEntity : class, IEntity
    {
        protected XxxxxRepositoryBase(IDbContextProvider dbContextProvider)
            : base(dbContextProvider)
        {
        }

        // Add your common methods for all repositories

        // Add your common methods for all repositories
        public int ExecuteNonQuery(string sql)
        {
            return MsSqlHelper.ExecuteNonQuery(GetTransaction() as SqlTransaction, CommandType.Text, sql);
        }

        public string ExecuteQueryString(string sql)
        {
            return (string)MsSqlHelper.ExecuteScalar(GetTransaction() as SqlTransaction, CommandType.Text, sql);
        }

        public DataTable ExecuteQuery(string sql)
        {
            var ds = ExecuteQueryDataSet(sql);
            if (null == ds)
            {
                return null;
            }

            return ds.Tables[0];
        }

        public DataTable ExecuteQuery(string sql, IDbDataParameter[] dbParameters)
        {
            DataSet ds = MsSqlHelper.ExecuteDataset(GetTransaction() as SqlTransaction, sql, dbParameters);
            if (null != ds && ds.Tables.Count > 0)
            {
                return ds.Tables[0];
            }
            else
            {
                return null;
            }
        }

        public DataSet ExecuteQueryDataSet(string sql)
        {
            return MsSqlHelper.ExecuteDataset(GetTransaction() as SqlTransaction, CommandType.Text, sql);
        }

        public DataTable RunProcTable(string procName, params SqlParameter[] dbParameters)
        {
            DataSet ds = RunProc(procName, dbParameters);
            if (null != ds && ds.Tables.Count > 0)
            {
                return ds.Tables[0];
            }
            else
            {
                return null;
            }
        }

        public DataSet RunProc(string procName, SqlParameter[] dbParameters)
        {
            var ds = MsSqlHelper.ExecuteDataset(GetTransaction() as SqlTransaction, CommandType.StoredProcedure, procName, dbParameters);
            return ds;
        }

        public int RunProc(string procName)
        {
            return MsSqlHelper.ExecuteNonQuery(GetTransaction() as SqlTransaction, CommandType.StoredProcedure, procName);
        }
    }

    /// 

    /// Base class for custom repositories of the application.
    /// This is a shortcut of  for  primary key.
    /// 
    /// Entity type
    public abstract class XxxxxRepositoryBase : XxxxxRepositoryBase, IRepository
        where TEntity : class, IEntity
    {
        protected XxxxxRepositoryBase(IDbContextProvider dbContextProvider)
            : base(dbContextProvider)
        {
        }

        // Do not add any method here, add to the class above (since this inherits it)!!!
    }
}
