问题 In Visual Studio 2010 do you have the ability to compare the data of a database between 2 databases. I wanted to use this to copy data from one database to another. These databases have the exact same structure. But when I do a compare I see only 65 tables showing up in de DataCompare view in VS2010 but I have 66 tables in the database. The next step was to find out which table not was showing up. The name of this table is 'CMS_PluginInstanceRouteParams'. This table is also present in both

问题 I'm attempting to compare two arrays of hashes with very similar hash structure (identical and always-present keys) and return the deltas between the two--specifically, I'd like to capture the folllowing: Hashes part of array1 that do not exist in array2 Hashes part of array2 that do not exist in array1 Hashes which appear in both data sets This typically can be achieved by simply doing the following: deltas_old_new = (array1-array2) deltas_new_old = (array2-array1) The problem for me (which

Best way to compare contents of two tables in Teradata?

问题 When you need to compare two tables to see what the differences are, are there any tools or shortcuts you use, or do you handcode the SQL to compare the two tables? Basically the core features of a product like Red Gate SQL Data Compare (schemas for my tables typically always match). Background: In my SQL Server environment, I created a stored procedure which inspects the metadata of the two tables/views, creates a query (as dynamic sql) which joins the two tables on the specified key columns

问题 I have 2 columns of data that I need to compare with each other - Column A and Column B.

I need to find out which of the values in column B are also in column A.

Visual Studio SSDT Data Compare how to compare two tables in a single database

由 不羁的心 提交于 2019-12-04 21:53:22
问题 Trying to do something simple Data Compare in SSDT but proving a bit hard. In one database, I have two tables I want to compare. These tables have the same schema, just different table names. And I just want to see if this tool will give me a nice way to compare the data in both. I.e. tblOutput tblOutput_210314 But this picking of two tables to compare against each other in a single database I can't see how to achieve. Seems like you can only pick a table name which exists in both source and
