sql server 快照
In the last articles, we have learned Configuring Snapshot and Transactional SQL Server replication and Configuring Peer to Peer and Merge SQL replication. Now, once we configured SQL Server replication, there will be some instances where we need to modify the SQL Server replication configuration as per the project updates. In this article, we will learn a few modifications in the existing SQL Replication such as Add new article, drop an article and change the Snapshot folder path and data filter in the current SQL Server replication.
在上一篇文章中，我們學(xué)習(xí)了配置快照和事務(wù)型SQL Server復(fù)制以及配置點(diǎn)對點(diǎn)和合并SQL復(fù)制 。 現(xiàn)在，一旦我們配置了SQL Server復(fù)制，就會(huì)有一些實(shí)例需要根據(jù)項(xiàng)目更新來修改SQL Server復(fù)制配置。 在本文中，我們將學(xué)習(xí)對現(xiàn)有SQL復(fù)制的一些修改，例如添加新文章，刪除文章并更改當(dāng)前SQL Server復(fù)制中的Snapshot文件夾路徑和數(shù)據(jù)過濾器。

將新文章添加到現(xiàn)有已發(fā)布的數(shù)據(jù)庫中 (Add new Articles into the existing published database)
In this section, we will learn, Add a new article into the existing published database. Once we created the publication, the publication contains few sets of database objects like tables, views and stored procedures. As per the project requirement sometimes we need to create new tables or views or stored procedures into the existing published database for some calculations or storing specific limited data. If we also wish to replicate those tables or views or stored procedures into the current SQL replication, then we need to add new database objects into the published database. This section will help to insert new articles into the existing published database of the SQL Server replication.
在本節(jié)中，我們將學(xué)習(xí)將新文章添加到現(xiàn)有已發(fā)布的數(shù)據(jù)庫中。 創(chuàng)建發(fā)布后，發(fā)布包含幾組數(shù)據(jù)庫對象，例如表，視圖和存儲(chǔ)過程。 根據(jù)項(xiàng)目要求，有時(shí)我們需要在現(xiàn)有的已發(fā)布數(shù)據(jù)庫中創(chuàng)建新表或視圖或存儲(chǔ)過程，以進(jìn)行一些計(jì)算或存儲(chǔ)特定的有限數(shù)據(jù)。 如果我們還希望將這些表或視圖或存儲(chǔ)過程復(fù)制到當(dāng)前SQL復(fù)制中，則需要將新的數(shù)據(jù)庫對象添加到已發(fā)布的數(shù)據(jù)庫中。 本節(jié)將幫助將新文章插入到SQL Server復(fù)制的現(xiàn)有已發(fā)布數(shù)據(jù)庫中。
I have already configured the transactional SQL replication on the node SQL1 for the database AdventuresWorksLT2012 as shown in the following fig.

數(shù)據(jù)庫AdventureWorksLT_2012的 客戶表是SQL Server復(fù)制的一部分。 我們將嘗試如下刪除它； 但是，它不允許我們刪除它，因?yàn)樵赟QL復(fù)制中配置為項(xiàng)目的表會(huì)引發(fā)錯(cuò)誤，如下所示。
Before dropping a table, first, we need to remove a table from the publication. Right-click publication and Go to Publication Properties. So, we want to drop a table Customer, so Let’s uncheck it from the list of objects to publish section. Once we uncheck it, we will get a pop-up warning click Yes.

更改快照文件夾路徑 (Change Snapshot folder Path)
While configuring SQL Server Distribution database, we had given the following snapshot folder path. In this section, we will learn to change the snapshot folder path in the from the current distribution.
在配置SQL Server Distribution數(shù)據(jù)庫時(shí)，我們給出了以下快照文件夾路徑。 在本節(jié)中，我們將學(xué)習(xí)從當(dāng)前發(fā)行版更改的快照文件夾路徑。

資料篩選器 (Data Filter)
SQL Server replication provides an excellent feature to filter the data using the Column data filter. In the data filter, we will able to show the column which we want to display for the reposting purpose. We can remove the column which contains sensitive information like customer name, customer email, credit card, etc.
SQL Server復(fù)制提供了一項(xiàng)出色的功能，可以使用列數(shù)據(jù)篩選器篩選數(shù)據(jù)。 在數(shù)據(jù)過濾器中，我們將能夠顯示要重新發(fā)布的列。 我們可以刪除包含敏感信息的列，例如客戶名稱，客戶電子郵件，信用卡等。
In the project environment, we build a dashboard in the tableau framework. Client vendors used to access those tableau dashboards for data analysis purposes. In that, we want to show data information of the one particular vendor to that specific vendor only. We do not want to show one vendor information to another vendor. So to limit data visibility, we will set-up SQL Server replication with data filter option.
在項(xiàng)目環(huán)境中，我們在tableau框架中構(gòu)建一個(gè)儀表板。 客戶端供應(yīng)商過去曾訪問這些Tableau儀表板以進(jìn)行數(shù)據(jù)分析。 這樣，我們只想向該特定賣方顯示一個(gè)特定賣方的數(shù)據(jù)信息。 我們不想將一個(gè)供應(yīng)商信息顯示給另一供應(yīng)商。 因此，為了限制數(shù)據(jù)可見性，我們將使用數(shù)據(jù)過濾器選項(xiàng)設(shè)置SQL Server復(fù)制。
Once the distribution database configured, we will proceed to set the publication.
配置分發(fā)數(shù)據(jù)庫后，我們將繼續(xù)設(shè)置發(fā)布。
Right-click Replication folder and select New Publication. Select the database AdventureWorksLT2012 as the following and click Next
右鍵單擊復(fù)制文件夾，然后選擇新建發(fā)布 。 選擇數(shù)據(jù)庫AdventureWorksLT2012 ，如下所示，然后單擊“下一步”。
Select the required database objects and click Next
選擇所需的數(shù)據(jù)庫對象，然后單擊“ 下一步”。
In the Filter Table Rows window, if we do not want to filter data, we can skip this step. Now we need to filter data so that we will configure this section window. Click on Add as shown in the following.
在“ 過濾表行”窗口中，如果不想過濾數(shù)據(jù)，則可以跳過此步驟。 現(xiàn)在我們需要過濾數(shù)據(jù)，以便我們配置此部分窗口。 單擊添加 ，如下所示。
Select the table we need to use for the data filter. We selected the table Customer from the SalesLT schema. Next, we need to add the column which contains sensitive information on the right-side filter statement. We will apply the condition for the specified column, and it will show the results only for the conditional statement.
選擇我們需要用于數(shù)據(jù)過濾器的表。 我們從SalesLT模式中選擇了表Customer 。 接下來，我們需要在右側(cè)的filter語句上添加包含敏感信息的列。 我們將條件應(yīng)用于指定的列，并且它將僅顯示條件語句的結(jié)果。
In this case, we added the column CompanyName for the condition; company name starts with A
在這種情況下，我們?yōu)闂l件添加了CompanyName列； 公司名稱以A開頭
Once we added the table Customer in the filter section as shown in the following fig.
一旦我們在過濾器部分中添加了表Customer ，如下圖所示。
In the Snapshot section, select a checkbox for Create a snapshot and click Next.
在“ 快照”部分中 ，選中“ 創(chuàng)建快照”復(fù)選框，然后單擊“ 下一步” 。
In the Agent Security, configure the service account for the snapshot agent and the log reader agent as the following and click Next.
在“ 代理安全性”中 ，如下配置快照代理和日志讀取器代理的服務(wù)帳戶，然后單擊“下一步”。
In the complete wizard window, provide publication name as the following and click Finish.
在完整的向?qū)Т翱谥?/span> ，提供以下發(fā)布名稱，然后單擊“ 完成” 。
Publication is configured successfully as the following.
發(fā)布成功配置如下。

訂戶上的數(shù)據(jù)驗(yàn)證 (Data Verification on the Subscriber)
In this step, we will verify the data; On the Publisher server SQL1, we will retrieve records from the table Customer. We can see, the column CompanyName shows the values for all the company name.
在這一步中，我們將驗(yàn)證數(shù)據(jù)； 在發(fā)布服務(wù)器SQL1上，我們將從表Customer中檢索記錄。 我們可以看到， CompanyName列顯示了所有公司名稱的值。
In this step, we will verify the data on the Subscriber server SQL2. When we retrieved records for the same table on the subscriber server SQL2, we will get filter data for the condition which we have specified in the filter section. We got the company name which starts with only character A as shown in the following fig.
在此步驟中，我們將驗(yàn)證訂閱服務(wù)器SQL2上的數(shù)據(jù)。 當(dāng)我們在訂閱服務(wù)器SQL2上檢索同一表的記錄時(shí)，我們將獲得在filter部分中指定的條件的過濾器數(shù)據(jù)。 我們得到的公司名稱僅以字符A開頭，如下圖所示。
