Delphi 执行SQL脚本/执行SQL GO 脚本语句

注意：文件的编码格式，最好要统一，ANSI编码或UNICODE编码

方法1：

var
  s: string;
  sqltext: string;
  sqlfile: TextFile;
begin
  if OpenDialog1.Execute then
  begin
    AssignFile(sqlfile, OpenDialog1.FileName);
    FileMode := 0;
    Reset(sqlfile);
    try
      ADOConnection1.BeginTrans;
      while not eof(sqlfile) do
      begin
        Readln(sqlfile, s);
        sqltext := s;
        while (not eof(sqlfile)) and (uppercase(trim(s)) <> ‘GO‘) do
        begin
          Readln(sqlfile, s);
          if (uppercase(trim(s)) <> ‘GO‘) then
            sqltext := sqltext + ‘ ‘ + s;
        end;
        adoquery1.Close;
        adoquery1.SQL.Clear;
        adoquery1.SQL.Add(sqltext);
        adoquery1.ExecSQL;
      end;
      CloseFile(sqlfile);
      ADOConnection1.CommitTrans;
      application.MessageBox(‘SQL执行完成！‘, ‘提示‘, MB_OK + MB_ICONINFORMATION);
    except
      raise exception.Create(‘SQL执行失败!‘);
      ADOConnection1.RollbackTrans;
    end;
  end;
end;

方法2：（这里要注意：脚本语句中 go 一定要换行）

var
  I: Integer;
  S: string;
begin
 with TStringList.Create do
 try
    LoadFromFile(‘test.sql‘);
    S := ‘‘;
    for I := 0 to Count - 1 do begin
      if SameText(Trim(Strings[I]), ‘GO‘) then begin  // SameText 不区分大小写  读取到GO 就执行一次代码
         with ADOQuery1 do begin
           Close;SQL.Clear;
           SQL.Text:=sSQL;
           ExecSQL;
         end;
        S := ‘‘;
      end else S := S + Strings[I] + #13#10;
    end;
    if S <> ‘‘ then
     begin
       with ADOQuery1 do begin
          Close;SQL.Clear;
          SQL.Text:=sSQL;
          ExecSQL;
       end;
     end;
 finally
     Free;
 end;
 end;
