Fetching table names from sql queries

  • We have several hundreds of tables in a database (OLTP system). Only few tables are being used by reports. We were planning to replicate only tables that are being used by reports to a different server. Is there a way to go through all queries used by SSRS reports and return tables names?

    I found below query online but it just gives me reports queries. I'm not sure how to retrieve table/view names. Any help would be greatly appreciated. Thank you.

    here is the query:

    WITH XMLNAMESPACES ( DEFAULT 'http://schemas.microsoft.com/sqlserver/reporting/2010/01/reportdefinition', 'http://schemas.microsoft.com/SQLServer/reporting/reportdesigner' AS rd )

    SELECT ReportName= name

    ,DataSetName= x.value('(@Name)[1]', 'VARCHAR(250)')

    ,DataSourceName= x.value('(Query/DataSourceName)[1]','VARCHAR(250)')

    ,CommandText= x.value('(Query/CommandText)[1]','VARCHAR(max)')

    ,Fields= df.value('(@Name)[1]','VARCHAR(250)')

    ,DataField= df.value('(DataField)[1]','VARCHAR(250)')

    ,DataType= df.value('(rd:TypeName)[1]','VARCHAR(250)')

    --,ConnectionString = x.value('(ConnectionProperties/ConnectString)[1]','VARCHAR(250)')

    FROM ( SELECT C.Name,CONVERT(XML,CONVERT(VARBINARY(MAX),C.Content)) AS reportXML

    FROM ReportServer.dbo.Catalog C

    WHERE C.Content is not null

    AND C.Type = 2

    ) a

    CROSS APPLY reportXML.nodes('/Report/DataSets/DataSet') r ( x )

    CROSS APPLY x.nodes('Fields/Field') f(df)

    ORDER BY name

  • There is no easy way to do this. Each report can be an ad hoc T-SQL statement, a stored procedure or a view. You can at least document the dependencies of the view in a straight forward manner. You can do this for stored procedures too, if they're not dynamic T-SQL under the covers. Ad hoc queries within reports have to be parsed.
