Hello I have the stored procedure that I need to run on several databases. It is stored in the master database.
The issue is when the following queries are run it only returns tables from the master database. Is there a way to do something like a "USE" database in the stored proc? I know you can not actually use the the "USE" command. I basically need to be able to run this sp on any given database and have the below queries return tables and indexes from that database, not master.
SELECT TABLE_CATALOG + '.' + TABLE_SCHEMA + '.' + TABLE_NAME
FROM INFORMATION_SCHEMA.TABLES
WHERE TABLE_TYPE = 'BASE TABLE'
SELECT table_catalog + '.' + table_schema + '.' + ObjectName, ObjectId, IndexName, IndexId, LogicalFrag
FROM #fraglist, INFORMATION_SCHEMA.TABLES
WHERE #fraglist.ObjectName = INFORMATION_SCHEMA.TABLES.TABLE_NAME
AND LogicalFrag >= @maxfrag
AND INDEXPROPERTY (ObjectId, IndexName, 'IndexDepth') > 0
CREATE PROCEDURE [dbo].[sp_RebuildIndxs]
AS
SET NOCOUNT ON
DECLARE @tablename VARCHAR (128)
DECLARE @execstr VARCHAR (255)
DECLARE @objectid INT
DECLARE @indexid INT
DECLARE @indexname VARCHAR (255)
DECLARE @frag DECIMAL
DECLARE @maxfrag DECIMAL
DECLARE @fillfactor INT
-- Decide on the maximum fragmentation to allow
SELECT @maxfrag = 1.0
SELECT @fillfactor = 70
-- Declare cursor
DECLARE tables CURSOR FOR
SELECT TABLE_CATALOG + '.' + TABLE_SCHEMA + '.' + TABLE_NAME
FROM INFORMATION_SCHEMA.TABLES
WHERE TABLE_TYPE = 'BASE TABLE'
-- Create the table
CREATE TABLE #fraglist (
ObjectName CHAR (255),
ObjectId INT,
IndexName CHAR (255),
IndexId INT,
Lvl INT,
CountPages INT,
CountRows INT,
MinRecSize INT,
MaxRecSize INT,
AvgRecSize INT,
ForRecCount INT,
Extents INT,
ExtentSwitches INT,
AvgFreeBytes INT,
AvgPageDensity INT,
ScanDensity DECIMAL,
BestCount INT,
ActualCount INT,
LogicalFrag DECIMAL,
ExtentFrag DECIMAL)
-- Open the cursor
OPEN tables
-- Loop through all the tables in the database
FETCH NEXT
FROM tables
INTO @tablename
PRINT RTRIM(@tablename)
WHILE @@FETCH_STATUS = 0
BEGIN
-- Do the showcontig of all indexes of the table
INSERT INTO #fraglist
EXEC ('DBCC SHOWCONTIG (''' + @tablename + ''')
WITH FAST, TABLERESULTS, ALL_INDEXES, NO_INFOMSGS')
FETCH NEXT
FROM tables
INTO @tablename
END
-- Close and deallocate the cursor
CLOSE tables
DEALLOCATE tables
-- Declare cursor for list of indexes to be defragged
DECLARE indexes CURSOR FOR
SELECT table_catalog + '.' + table_schema + '.' + ObjectName, ObjectId, IndexName, IndexId, LogicalFrag
FROM #fraglist, INFORMATION_SCHEMA.TABLES
WHERE #fraglist.ObjectName = INFORMATION_SCHEMA.TABLES.TABLE_NAME
AND LogicalFrag >= @maxfrag
AND INDEXPROPERTY (ObjectId, IndexName, 'IndexDepth') > 0
-- Open the cursor
OPEN indexes
-- loop through the indexes
FETCH NEXT
FROM indexes
INTO @tablename, @objectid, @indexname, @indexid, @frag
WHILE @@FETCH_STATUS = 0
BEGIN
PRINT 'Executing ALTER INDEX ' + RTRIM(@indexname) + ' ON ' + RTRIM(@tablename) + ' REBUILD WITH (FILLFACTOR = ' + CAST(@fillfactor AS CHAR(3)) + ')'
SELECT @execstr = 'ALTER INDEX ' + RTRIM(@indexname) + ' ON ' + RTRIM(@tablename) + ' REBUILD WITH (FILLFACTOR = ' + CAST(@fillfactor AS CHAR(3)) + ')'
EXEC (@execstr)
FETCH NEXT
FROM indexes
INTO @tablename, @objectid, @indexname, @indexid, @frag
END
-- Close and deallocate the cursor
CLOSE indexes
DEALLOCATE indexes
-- Delete the temporary table
DROP TABLE #fraglist
Any comments are greatly appreciated.
Thank you

'Use MyDatabase' should accomplish this
Since you asked specifically about "Use" I assume you have tried it and it didnt work?

You can not use a "USE " statement within a stored procedure. I am not sure what you are suggesting here. Could you please clarify?
Thank you

The best way to do that might be to set it up to be able to run from Master, but using the current DB's context.
Take a look at the following:

Your lack of planning does not constitute an emergency on my part...unless you're my manager...or a director and above...or a really loud-spoken end-user..All right - what was my emergency again?

This is perfect. It works! Thank you very much.
