fbScript.Parse() 中的 FirebirdClient 5.7 ADO.NET UnknownStatement

Question

我使用过 FirebirdClient 2.0 ADO.NET，我正在迁移到 FirebirdClint 5.7 版 ADO.NET。

下面的代码在新版本的 firebirdClient 中不起作用

If IO.File.Exists(pathScript) Then
        txtScript.Close()

        Dim fbScript As New FbScript(pathScript)

        fbScript.Parse()
        If fbScript.Results.Count = 0 Then
            Exit Sub
        End If

        If fbScript.Results.Count > 0 Then
            If automatico = False Then
                frmImpSintegra.LblTitulo.Text = "Gravando 60I"
            End If
            Application.DoEvents()

            Dim fbConn As New FbConnection(cnEmpresa)
            fbConn.Open()

            Dim fbBatch As New FirebirdSql.Data.Isql.FbBatchExecution(fbConn)
            fbBatch.AppendSqlStatements(fbScript)
            fbBatch.Execute(True)
            fbConn.Close()
        End If

        deleteArquivoTemporario()
        txtScript = New IO.StreamWriter(pathScript)
    End If

这个错误出现在行fbScript.Parse()

我的 txt 文件是：

INSERT INTO REGISTRO_60I12 (TIPO,SUBTIPO,DATA_EMISSAO,NUMERO_SERIE,MODELO,COO,ITEM,PRODUTO_SERVICO,QUANTIDADE,VALOR_LIQUIDO,BASE_CALCULO,ALIQUOTA_SUBSTITUICAO,VALOR_ICMS,MESANO,EMPRESA)VALUES('60','I','2016.12.09','BE090910100010004937','2D',320645,'001','12036',1.000,3.99,0.00,'F',0.00,122016,0556);

有人可以帮助我吗？

Answer 1

您正在将文件名传递给 FbScript 的构造函数，但此构造函数需要实际的脚本内容。这导致文件名 c:56_16122016_081323.txt 被解析为一个语句，而 c:56_16122016_081323.txt 不是已知的 Firebird 语句。

您应该使用 FbScript.LoadFromFile(pathScript)。
