Should I Replace My FOR XML PATH String Merges with String_agg?

By Jeffry Schwartz | Function , Performance Tuning , Query Tuning , SQL Development , SQL Server

Overview If you are looking for major performance gains, the answer is no.  However, if you are using SQL Server 2017 and developing new code, you should consider using the new String_agg function that is available on SQL Server 2017 because code that uses this function is so much more readable and easier to write […]

Finding Table Defaults, Primary and Unique Keys and Foreign Keys with sp_helpconstraint

By Lori Brown | Dependencies , Object Information , SQL Administration , SQL Development , SQL Server

A little while back I wrote a post going over sp_help in a beginning effort to find table dependency information.  https://www.sqlrx.com/using-sp_help-to-find-object-dependencies/.  That expanded to reviewing sys.dm_sql_referenced_entities & sys.dm_sql_referenced_entities  (https://www.sqlrx.com/finding_things_sql_that_reference_a_table/ & https://www.sqlrx.com/how-to-find-the-objects-and-columns-a-stored-procedure-or-view-uses/ ) and sys.sql_expression_dependencies (https://www.sqlrx.com/using-sys-sql_expression_dependencies-as-a-single-source-to-find-referenced-and-referencing-objects/  ) Now I want to loop back just a bit and expand on more information that is found in sp_help […]

Using sys.sql_expression_dependencies as a Single Source to Find Referenced and Referencing Objects

I thought I would continue to expand on ways to view dependencies.  This post will give you an alternate way to find things referencing tables and finding things that are referenced by a stored procedure or view after my previous posts on the subject.  See these (https://www.sqlrx.com/finding_things_sql_that_reference_a_table/ & https://www.sqlrx.com/how-to-find-the-objects-and-columns-a-stored-procedure-or-view-uses/ ) A different way to find […]

How To Find the Objects and Columns a Stored Procedure or View Uses

By Lori Brown | Dependencies , Object Information , SQL Administration , SQL Development , SQL Server

In my last post I covered finding objects that reference another object using the dmf, sys.dm_sql_referencing_entities.  (https://www.sqlrx.com/finding_things_sql_that_reference_a_table/ )  Now let’s reverse that and find what objects are referenced in stored procedures or views.  When updates are needed to business logic often that happens in these objects.  If the stored procedures or views are large with […]
