使用FireDac(Delphi)在Firebird中创建数据库 [英] Creating a database in Firebird using FireDac (Delphi)

问题描述

我最近从AnyDac更改为FireDac(8.0.5.3365).我们正在运行Delphi 2006.

I recently changed from AnyDac to FireDac (8.0.5.3365). We're running Delphi 2006.

当我使用此组件的AnyDac版本时，我可以通过执行以下操作来创建新数据库.

When I was using the AnyDac version of this component I could create a new database by doing the following..

设置我的连接

fConnection.LoginPrompt := false;
fConnection.ResourceOptions.SilentMode := true;

fConnection.Params.Clear;
fConnection.Params.Add(Format('DriverID=%s',          ['IB']));
fConnection.Params.Add(Format('Database=%s',          [fConnectionInfo.xDatabase]));
fConnection.Params.Add(Format('CharacterSet=%s',      ['UTF8']));
fConnection.Params.Add(Format('user_name=%s',         [fConnectionInfo.xUserName]));
fConnection.Params.Add(Format('password=%s',          [fConnectionInfo.xPassword]));
fConnection.Params.Add(Format('ExtendedMetadata=%s',  ['True']));
fConnection.Params.Add(Format('CreateDatabase=%s',    ['Yes']));
fConnection.Params.Add(Format('Protocol=%s',          ['Local']))

//database path = C:\Users\LoginName\AppData\Local\AppName\TestDB.FDB

打开和关闭连接

fConnection.Open;
fConnection.Close;

然后我可以在现有数据库上运行我的创建表sql脚本.

And then I could run my create table sql scripts on the existing database.

但是现在，当我使用FireDac版本执行此操作时，打开"命令会引发fbe_unavailable错误，就好像我没有指定CreateDatabase参数一样.

But now when I do this with the FireDac version, the Open command raises the fbe_unavailable error as if I didn't specify the CreateDatabase parameter.

我应该以不同的方式这样做吗?

Should I be doing this a different way?

感谢您的时间.

推荐答案

您在这里有完整的示例 http://docwiki.embarcadero.com/RADStudio/Rio/en/Executing_SQL_Scripts_%28FireDAC%29

You have a full example here http://docwiki.embarcadero.com/RADStudio/Rio/en/Executing_SQL_Scripts_%28FireDAC%29

例如，以下Firebird脚本创建一个数据库，并且可以使用TFDScript执行:

For example, the following Firebird script creates a database, and can be executed using TFDScript:

SET SQL DIALECT 3;
SET NAMES UTF8;
SET CLIENTLIB 'C:\fb25\bin\fbclient.dll';
CREATE DATABASE 'E:\Test2.ib'
  USER 'sysdba' PASSWORD 'masterkey'
  PAGE_SIZE 16384
  DEFAULT CHARACTER SET NONE;

SET TERM ^ ;

CREATE PROCEDURE MY_PROC RETURNS (aParam INTEGER) AS
BEGIN
  aParam = 10;
END^

您应该使用CreateDatabase = Yes连接定义参数 除其他必需参数外: http://docwiki.embarcadero.com/RADStudio/Rio/en/Connect_to_Firebird_ (FireDAC)

You should use CreateDatabase=Yes connection definition parameter additionally to other required parameters: http://docwiki.embarcadero.com/RADStudio/Rio/en/Connect_to_Firebird_(FireDAC)
