Question

我正在使用FirebirdSql.Data.FirebirdClient;

我有SQL查询：

"SELECT * FROM TB_CLIENTES C JOIN TB_CLIENTES_ENDERECOS E ON (E.CLIENTE_COD = C.CLIENTE_COD AND E.ENDERECO_TIPO_COD =1) WHERE C.CLIENTE_COD LIKE :filtro ORDER BY C.RAZAO_SOCIAL"

对于make选择im，使用此代码：

        string conexao = String.Format(integracao.Local, integracao.Usuario, integracao.Senha);
        DbConnection connection = null;
        DbCommand command = null;
        connection = new FbConnection(conexao);
        connection.Open();
        command = new FbCommand(@integracao.ConsultaSQL, (FbConnection)connection);
        if (integracao.TipoFiltro.Equals(TipoFiltroEnum.TEXTO)) { command.Parameters.Add(new FbParameter(":filtro", campoFiltro + "%")); }
        else { command.Parameters.Add(new FbParameter(":filtro", campoFiltro)); }
        DbDataReader dr = command.ExecuteReader();

我收到此异常：

FirebirdSql.Data.FirebirdClient.FbException: 'Dynamic SQL Error SQL error code = -206 Column unknown FILTRO At line 1, column 146' IscException: Dynamic SQL Error SQL error code = -206 Column unknown FILTRO At line 1, column 146

编辑：更改：到@filtro并解决问题

Firebird ADO.net提供程序中的参数应以infile = open("empwages.txt","r") masterList = infile.readlines() nameList = [] hourList = [] plushourList = [] for master in masterList: nameList.append(master.split()[0]) hourList.append(master.split()[1]) x = 2 while x <= 6: plushourList.append(master.split()[x]) x += 1 print(nameList) print(hourList) print(plushourList)符号而不是@开头。

只需将您的代码更改为使用:，它就可以正常工作。

SQL代码段：

C＃代码段：

... WHERE C.CLIENTE_COD LIKE @filtro ORDER BY ...
