The database principal owns a schema in the database, and cannot be dropped. – Fix

If you try to drop a user that owns a schema, you will receive the following error message: [code] The database principal owns a schema in the database, and cannot be dropped. [/code] In order to drop the user, you need to find the schemas they are assigned, then transfer the ownership to another user or role [cc lang=”sql”] SELECT FROM sys.schemas s WHERE s.principal_id = USER_ID(‘joe’) — now use the names you find from the above query below in place of the SchemaName below ALTER AUTHORIZATION ON SCHEMA::SchemaName TO dbo [/cc]

SQL Server 2008 Minimally Logged Inserts

SQL Server 2008 has now introduced minimally logged inserts into tables that already contain data and a clustered index. What happens is the initial inserts may be fully logged if the data pages they are filling already contain data. However any new data pages added to the table will be minimally logged if all the requirements below are met. Trace flag 610 must be on Database recovery model must be bulk-logged or Simple Inserted data must be ordered by the clustered index To turn on the trace flag for your current session: [cc lang=”sql”] DBCC TRACEON (610) INSERT INTO dbo.MyTable SELECT * FROM ORDER BY 1 DBCC TRACEOFF (610) [/cc] This new change differs dramatically from the previous requirements for minimal logging. Previously there could be no clustered index and a table lock had to be acquired on the target table. For more information, visit: Minimal Logging Changes – MSDN Blog

Find Dependent Objects

One new feature that SQL Server 2008 offers is more reliable dependency information. SQL Server 2005 offered a DMV (dynamic management view) called sys.sql_dependencies. It is now replaced by a more reliable sys.sql_expression_dependencies. The following script will show all the procedures that reference a given table name, along with the columns the procedure references also. Please note, this does not take into account any dynamic SQL. [cc lang=”sql”] USE MYDatabase GO DECLARE @TableName varchar(100) SET @TableName = ‘mytable’ SELECT SourceSchema = OBJECT_SCHEMA_NAME(sed.referencing_id) ,SourceObject = OBJECT_NAME(sed.referencing_id) ,ReferencedDB = ISNULL(sre.referenced_database_name, DB_NAME()) ,ReferencedSchema = ISNULL(sre.referenced_schema_name, OBJECT_SCHEMA_NAME(sed.referencing_id)) ,ReferencedObject = sre.referenced_entity_name ,ReferencedColumnID = sre.referenced_minor_id ,ReferencedColumn = sre.referenced_minor_name FROM sys.sql_expression_dependencies sed CROSS APPLY sys.dm_sql_referenced_entities(OBJECT_SCHEMA_NAME(sed.referencing_id) + ‘.’ + OBJECT_NAME(sed.referencing_id), ‘OBJECT’) sre WHERE sed.referenced_entity_name = @TableName AND sre.referenced_entity_name = @TableName [/cc]

Insert Carriage Return Line Feed to String

Here is a clean and efficient way to embed carriage returns into a string. I prefer this way instead of concatenating the entire CHAR(13)+CHAR(10) to the end of every string. This replace function also comes in handy in most instances where you need to append strings. [cc lang=”sql”] declare @Note varchar (200) SET @Note = ‘Line One.[crlf];Line Two[crlf]Line Three.’ SET @Note = REPLACE(@Note,'[crlf]’,CHAR(13)+CHAR(10)) PRINT @Note [/cc] Output: [code] Line One. Line Two. Line Three. [/code]
