powerbi - Merge multiple database snapshots into one database in SQL Server? -


i'm trying figure out how merge database snapshots 1 database. each month creating database snapshot data static , represent specific month. reason want data static because power bi report needs show data of how @ moment of taking snapshot.

because not able merge monthly database snapshots 1 database, have duplicate power bi report , change database name(of specific database snapshot) have query on extract dataset.

is possible combine multiple database snapshots(e.g. snapshot_jan17 , snapshot_feb17) 1 database can access snapshotted data single power bi report , add identifier each table representing specific snapshot month(for filtering purposes)?

enter image description here

potentially relevant problem. regarding

i have duplicate power bi report , change database name

in short, can have "empty query" variables server/database names, use these in queries, , change data source in single place, rather in every single query of report.

preventing data source string duplication

by default, when data imported powerbi desktop, each table or query stores data source details separately, if use same data source.

this makes tedious, example, change source database of entire powerbi report - requires changing each query source parameter individually.

there way simplify this, described here.

  1. import data would. example: data source type - sql server, server name - localhost, database - test1, tables - table1, table2.

  2. in query editor, add 2 blank queries: "get data" -> "blank query", servername value = "localhost", databasename value = "test1". enter image description here

  3. for each table on "queries" pane on left, select "source" in "query settings" on right, substitute server , database names parameters created in step 2. enter image description here enter image description here enter image description here

  4. now when need update connection string, change servername or databasename , refresh data.
