I am trying to merge two different rules into one that should run in two databases server.
I did merged the files. but i am stuck at the this columns.
There are two columns with different names but the same data in the two databases. I want my query to check if if this column exist
First column - APE.RecProdOwner
Second Column - APE.ReconciliationOwner
I want my query to check for both these columns in the database and if one of the two exists then it should store the data into the new column name as “RecProdOwner”
You can use an EXISTS against the sys objects, and then simply use sys.sp_rename to rename the column:
USE Sandbox;
GO
CREATE TABLE dbo.YourTable ([APE.RecProdOwner] int,
ReconciliationOwner int);
GO
IF EXISTS (SELECT 1
FROM sys.schemas s
JOIN sys.tables t ON s.schema_id = t.schema_id
JOIN sys.columns c ON t.object_id = c.object_id
WHERE s.name = N'dbo'
AND t.name = N'YourTable'
AND c.name = N'APE.RecProdOwner')
EXEC sys.sp_rename N'dbo.YourTable.[APE.RecProdOwner]','RecProdOwner','COLUMN';
IF EXISTS (SELECT 1
FROM sys.schemas s
JOIN sys.tables t ON s.schema_id = t.schema_id
JOIN sys.columns c ON t.object_id = c.object_id
WHERE s.name = N'dbo'
AND t.name = N'YourTable'
AND c.name = N'APE.ReconciliationOwner')
EXEC sys.sp_rename N'dbo.YourTable.[APE.ReconciliationOwner]','ReconciliationOwner','COLUMN';
GO
SELECT *
FROM dbo.YourTable;
GO
DROP TABLE dbo.YourTable;
I have a prod database that is very large in size. I need to copy this DB to make a test environment, however there is not enough disk space.
But actually there is no need to copy rows from tables containing user-data, only those tables that describe functionality are necessary. For tables with user-data I only need to copy table "description" (columns, indexes, triggers, ...).
How (with what query) can I estimate the size of DB without data from some tables?
SET NOCOUNT ON
DBCC UPDATEUSAGE(0)

CREATE TABLE #t

SELECT
schema_qualified_table = s.name + '.' + t.name,
KB = SUM(ps.reserved_page_count) * 8192/1024.0
FROM sys.tables AS t
INNER JOIN sys.schemas AS s ON t.[schema_id] = s.[schema_id]
INNER JOIN sys.dm_db_partition_stats AS ps

WHERE s.name + '.' + t.name IN (N'dbo.table1', N'dbo.table2', ...)
-- list of tables you do care about ^^^^^^^^^^ ^^^^^^^^^^
GROUP BY s.name + '.' + t.name;
A little tidier might be:
;WITH x AS
(
SELECT o = t.[object_id], n = s.name + '.' + t.name
FROM sys.tables AS t
INNER JOIN sys.schemas AS s
ON t.[schema_id] = s.[schema_id]
)
SELECT
schema_qualified_table = x.n,
KB = SUM(ps.reserved_page_count) * 8192/1024.0
FROM x INNER JOIN sys.dm_db_partition_stats AS ps
ON x.o = ps.[object_id]
WHERE x.n IN (N'dbo.table1', N'dbo.table2', ...);
Posting my expansion to Aaron Bertrand's answer, just for readability. Only difference is adding the join to the SCHEMAS table, and including schema name in the output and group by.
SELECT
s.name,
t.name,
KB = SUM(ps.reserved_page_count) * 8192/1024.0
FROM sys.tables AS t
INNER JOIN sys.dm_db_partition_stats AS ps
ON t.[object_id] = ps.[object_id]
INNER JOIN sys.schemas S
ON t.schema_id = s.schema_id
WHERE t.name IN (<YOUR TABLES GO HERE) -- list of tables you do care about
GROUP BY t.name,
s.name;
As Aaron has rightly pointed out, trying to filter on a combination of tables and schemas could get ugly very fast. You could easily end up with a huge collection of ORs:
(S.SCHEMA = 'SCHEMA1' and T.NAME = 'FOO')
OR
(S.SCHEMA = 'SCHEMA2' and T.NAME = 'FOO')
OR
(S.SCHEMA = 'SCHEMA1' and T.name = 'BAR')
...
Is there a query that returns the names of all the stored procedures in a SQL Server database that some or all his parameter has varchar datatype, and we can change it because we change all database table from varchar to nvarchar and there are a lot of stored procedures to change then maybe it takes a whole day so please help me
Information_Schema has always helped me with these problems:
SELECT r.ROUTINE_NAME, p.PARAMETER_NAME
FROM
INFORMATION_SCHEMA.ROUTINES r INNER JOIN INFORMATION_SCHEMA.PARAMETERS p
ON r.SPECIFIC_CATALOG = p.SPECIFIC_CATALOG
AND r.SPECIFIC_SCHEMA = p.SPECIFIC_SCHEMA
AND r.SPECIFIC_NAME = p.SPECIFIC_NAME
WHERE
p.DATA_TYPE = 'varchar'
Sure - try this:
SELECT
ProcedureName = pr.Name,
ParameterName = p.Name,
TypeName = t.Name
FROM
sys.procedures pr
INNER JOIN
sys.parameters p ON p.object_id = pr.object_id
INNER JOIN
sys.types t ON p.system_type_id = t.system_type_id
WHERE
t.Name = 'varchar'
You might also want to search for parameters of type char (which need to be converted to nchar) and text (convert to ntext - or better yet: nvarchar(max) since text and ntext are deprecated and should not be used anymore)
Try this one -
SELECT
[procedure_name] = SCHEMA_NAME(o.[schema_id]) + '.' + o.name
, parameter_name = p.name
FROM sys.objects o WITH(NOWAIT)
JOIN sys.parameters p WITH(NOWAIT) ON p.[object_id] = o.[object_id]
WHERE TYPE_NAME(p.user_type_id) = 'varchar'
AND o.[type] IN ('P ', 'X ', 'PC', 'RF')
I have a complex query with several tables, views and functions within it. The functions and views split off into more views and functions that potentially split off into more views and functions within them.
This query is having performance issues so I want to get a clear and concise list of all the objects that are being referenced within my query so I have a basis for my investigation. How do I get this list of objects?
DESCRIPTION
Wrote this Stored Procedure below which RECURSIVELY lists all the dependent child objects and child's dependent objects and child's child...etc. The input parameter can be Stored Proc, User Function, View.
Can easily be altered to get a Unique List of Column 5, regardless of what Level the Object was called and how deep and by which object.
COLUMNS
UsedByObjectId - The parent object that uses the dependent object
UsedByObjectName - The name of the parent object
UsedByObjectType - Type of the parent object (P,V,FN)
DependentObjectId - The child object the parent uses
DependentObjectName - Name of the child object
DependentObjectType - Type of the dependent child object (P,V,FN, U)
Level - How deep, the nested recursive level which the object is used

I saw this post to identify all the objects that reference a particular synonym and used the base logic in the answer in a recursive CTE to identify all the objects related to a comma-delimited list of the objects within the top level query being executed.

Set #SQL = 'Select ss.name As SchemaName,
so.name As TableName,
so.id,
so.xtype
From sysobjects so
Join sys.schemas ss
On so.uid = ss.schema_id
Where so.id In (Object_ID(''' + Replace(#baseObjects,',','''),Object_ID(''') + '''))';

Check This one, You will get all recursive objects.

In SQL Server 2008 there are two new Dynamic Management Functions introduced to keep track of object dependencies: sys.dm_sql_referenced_entities and sys.dm_sql_referencing_entities:
1/ Returning the entities that refer to a given entity:
SELECT
referencing_schema_name, referencing_entity_name,
referencing_class_desc, is_caller_dependent
FROM sys.dm_sql_referencing_entities ('<TableName>', 'OBJECT')
2/ Returning entities that are referenced by an object:
SELECT
referenced_schema_name, referenced_entity_name, referenced_minor_name,
referenced_class_desc, is_caller_dependent, is_ambiguous
FROM sys.dm_sql_referenced_entities ('<StoredProcedureName>', 'OBJECT');
Another option is to use a pretty useful tool called SQL Dependency Tracker from Red Gate.
Based on #Raju Chavan's answer above, which works great. However...
I've added support for schemas, as well as returning (and ordering by) the recursion level, so one can easily turn it into a script to refresh referencing objects in the correct order, using sp_refreshsqlmodule (see point 3 below).
WITH
cRefobjects AS (
SELECT o.name, s.name AS sch, o.type_desc, 1 AS level
FROM sys.sql_expression_dependencies sed
INNER JOIN sys.objects o ON o.object_id = sed.referencing_id
INNER JOIN sys.schemas AS s ON s.schema_id = o.schema_id
WHERE (sed.referenced_schema_name = '<your schema>' OR sed.referenced_schema_name IS NULL)
AND sed.referenced_entity_name = '<your object name>'
UNION ALL
SELECT o.name, s.name AS sch, o.type_desc, cRefobjects.level + 1 AS level
FROM
sys.sql_expression_dependencies AS sed
INNER JOIN sys.objects o ON o.object_id = sed.referencing_id
INNER JOIN sys.schemas AS s ON s.schema_id = o.schema_id
INNER JOIN cRefobjects ON sed.referenced_entity_name = cRefobjects.name
AND sed.referenced_schema_name = cRefobjects.sch
)
SELECT DISTINCT name, sch, type_desc, level
FROM cRefobjects
ORDER BY level, type_desc DESC, name;
A few things to consider:
Replace <your schema> and <your object> with with what you require.
When the referenced object does not have a schema prefix in the referencing object, the schema is actually unknown, hence the predicate above OR sed.referenced_schema_name IS NULL. This may get the wrong referencing object if you're not following best practices in your database objects.
My goal in seeking and finding this answer was to write a script to refresh referenced objects in the database automatically after editing a view, using sp_refreshsqlmodule. To do this, just wrap the CTE shown above as follows. This prints the required SQL for refreshing the referencing objects in the correct order:
DECLARE #SQL NVARCHAR(4000); SET #SQL = '';
WITH
cRefobjects AS (
...
)
--SELECT DISTINCT name, sch, type_desc, level
SELECT #SQL = #SQL + 'EXEC sys.sp_refreshsqlmodule ''' + sch + '.' + name + '''' + CHAR(13)+CHAR(10)
FROM cRefobjects
ORDER BY level, type_desc DESC, name;
PRINT #SQL
I have improved above answers as none was working for me.
I needed a way to refresh complex nested objects by type sp_refreshsqlmodule.
You need to update and <TYPE_NAME> to your own.
Following method work for me:
WITH cRefobjects AS (
SELECT o.name, s.name AS sch, o.type, 1 AS level
FROM sys.sql_expression_dependencies sed
INNER JOIN sys.objects o ON o.object_id = sed.referencing_id
INNER JOIN sys.schemas AS s ON s.schema_id = o.schema_id
WHERE (sed.referenced_schema_name = '<SCHEMA>' OR sed.referenced_schema_name IS NULL)
AND sed.referenced_entity_name = '<TYPE_NAME>'
UNION ALL
SELECT o.name, s.name AS sch, o.type, cRefobjects.level + 1 AS level
FROM
sys.sql_expression_dependencies AS sed
INNER JOIN sys.objects o ON o.object_id = sed.referencing_id
INNER JOIN sys.schemas AS s ON s.schema_id = o.schema_id
INNER JOIN cRefobjects ON sed.referenced_entity_name = cRefobjects.name
AND sed.referenced_schema_name = cRefobjects.sch
)
SELECT name, MAX(level) as level, 'EXEC sys.sp_refreshsqlmodule #name = ''' + sch + '.' + name + '''', type
FROM cRefobjects
GROUP BY name, sch, type
ORDER BY level, type, name;
I need to modify a column definition, but I would like to check if the column is full text enabled first. Is there a way to do such a check in a TSQL script?
I'm using SQL Server 2005.
You could try using the COLUMNPROPERTY() function.
DECLARE #value INT;
SELECT #value = COLUMNPROPERTY(OBJECT_ID('schema.table'), 'column_name', 'IsFulltextIndexed')
IF (#value = 1)
PRINT 'Fulltext column'
ELSE
PRINT 'No Fulltext column'
You can try something like this:
SELECT *
FROM sys.columns c
INNER JOIN sys.fulltext_index_columns fic ON c.object_id = fic.object_id
AND c.column_id = fic.column_id
If you need to limit it to a given table, use this:
SELECT *
FROM sys.columns c
INNER JOIN sys.fulltext_index_columns fic ON c.object_id = fic.object_id
AND c.column_id = fic.column_id
WHERE c.object_id = OBJECT_ID('YourTableNameHere')
