使用SQL Server CE插入到数据库中

Question

我重新设计了我的项目3次，最后想到在我的应用程序变得太过失控之前我会问。我正在构建一个复杂的系统监控和报告生成应用程序。我一直在努力弄清楚哪种数据库方法最适合我的情况，我认为它是SQL Server CE，因为我在一台工作笔记本电脑上，可能需要长达一周的时间才能安装它。如果有更友好的应用程序，我应该使用，我愿意提供建议。

假设我坚持使用SQL Server CE，将记录插入到具有许多列的.sdf文件中的最佳方法是什么？例如，DB中的表格可以包含100列。它现在可以正常工作，但似乎每插入一行都需要大约1秒。该代码看起来是这样的（最终将有更多列）：

con.Open(); 

SqlCeTransaction trans = con.BeginTransaction(); 

String insertRecord = "INSERT INTO AS400_Objects(projectName, obBuildObjectName, " + 
        "obBuildLibrary, obBuildType, obBuildExtendedAttribute, obBuildFormatLevel, " + 
        "obBuildUserAttribute, obBuildChangeDate, obBuildCreationDate, " + 
        "obBuildCreatorSystem, obBuildCreatorUserProfile, obBuildJournal, " + 
        "obBuildJournalStatus, obBuildLastUsedDate, obBuildObjectSize, obBuildOwner, " + 
        "obBuildRestoreDate, obBuildSaveDate, obBuildSourceFile, " + 
        "obBuildSourceFileUpdatedDate, obBuildTextDescription, obBuildSystemVersion)" + 
        "VALUES(@projectName, @obBuildObjectName, @obBuildLibrary, @obBuildType, " + 
        "@obBuildExtendedAttribute, @obBuildFormatLevel, @obBuildUserAttribute, " + 
        "@obBuildChangeDate, @obBuildCreationDate, @obBuildCreatorSystem, " + 
        "@obBuildCreatorUserProfile, @obBuildJournal, @obBuildJournalStatus, " + 
        "@obBuildLastUsedDate, @obBuildObjectSize, @obBuildOwner, @obBuildRestoreDate, " + 
        "@obBuildSaveDate, @obBuildSourceFile, @obBuildSourceFileUpdatedDate, " + 
        "@obBuildTextDescription, @obBuildSystemVersion)"; 

SqlCeCommand cmd = new SqlCeCommand(insertRecord, con); 
cmd.Transaction = trans; 

cmd.Parameters.Clear(); 
cmd.Parameters.AddWithValue("@projectName", packageName); 
cmd.Parameters.AddWithValue("@obBuildObjectName", od[i].getValue(ObjectDescription.NAME).ToString()); 
cmd.Parameters.AddWithValue("@obBuildLibrary", od[i].getValue(ObjectDescription.LIBRARY).ToString()); 
cmd.Parameters.AddWithValue("@obBuildType", od[i].getValue(ObjectDescription.TYPE).ToString()); 
cmd.Parameters.AddWithValue("@obBuildExtendedAttribute", od[i].getValue(ObjectDescription.EXTENDED_ATTRIBUTE).ToString()); 
cmd.Parameters.AddWithValue("@obBuildFormatLevel", ""); 
cmd.Parameters.AddWithValue("@obBuildUserAttribute", od[i].getValue(ObjectDescription.USER_DEFINED_ATTRIBUTE).ToString()); 
cmd.Parameters.AddWithValue("@obBuildChangeDate", changeDate); 
cmd.Parameters.AddWithValue("@obBuildCreationDate", creationDate); 
cmd.Parameters.AddWithValue("@obBuildCreatorSystem", od[i].getValue(ObjectDescription.CREATOR_SYSTEM).ToString()); 
cmd.Parameters.AddWithValue("@obBuildCreatorUserProfile", od[i].getValue(ObjectDescription.CREATOR_USER_PROFILE).ToString()); 
cmd.Parameters.AddWithValue("@obBuildJournal", od[i].getValue(ObjectDescription.JOURNAL).ToString()); 
cmd.Parameters.AddWithValue("@obBuildJournalStatus", journalStatus); 
cmd.Parameters.AddWithValue("@obBuildLastUsedDate", lastUsedDate); 
cmd.Parameters.AddWithValue("@obBuildObjectSize", od[i].getValue(ObjectDescription.OBJECT_SIZE).ToString()); 
cmd.Parameters.AddWithValue("@obBuildOwner", od[i].getValue(ObjectDescription.OWNER).ToString()); 
cmd.Parameters.AddWithValue("@obBuildRestoreDate", restoreDate); 
cmd.Parameters.AddWithValue("@obBuildSaveDate", saveDate); 
cmd.Parameters.AddWithValue("@obBuildSourcefile", od[i].getValue(ObjectDescription.SOURCE_FILE).ToString()); 
cmd.Parameters.AddWithValue("@obBuildSourceFileUpdatedDate", sourceFileUpdatedDate); 
cmd.Parameters.AddWithValue("@obBuildTextDescription", od[i].getValue(ObjectDescription.TEXT_DESCRIPTION).ToString()); 
cmd.Parameters.AddWithValue("@obBuildSystemVersion", od[i].getValue(ObjectDescription.SYSTEM_LEVEL).ToString()); 

cmd.ExecuteNonQuery(); 
trans.Commit(CommitMode.Immediate); 

cmd.Dispose(); 

con.Close(); 
con.Dispose(); 

基于这种情况，是有什么我可以做以提高查询的性能？我来自AS400大型机世界，其中1秒钟会给你数百甚至数千行。该应用程序的最终结果是它将创建一个输出文件发送到某处，然后双击该文件将所有这些数据加载到远程机器上。我已经看过SqlCEAdapter，但一直没有找到一个很好的解释如何使用它来适应我的情况。

在此先感谢！

您是否听说过数据库规范化？这避免了数据的重复，并减少了每个INSERT所需的列数。如果没有CommitMode，这个过程也会运行得更快。最后，您可以使用SqlCeUpdateRecord和TableDirect绕过查询处理程序进行快速插入。
