Editor to share with you how to create partition SP and job in the database. I hope you will get something after reading this article. Let's discuss it together.

Create SP

Click (here) to collapse or open

Create procedure sp_maintain_partion_fg (

@ tableName varchar (50)

@ inputdate datetime

)

As begin

Declare

@ fileGroupName varchar (50)

@ ndfName varchar (50)

@ newNameStr varchar (50)

@ fullPath varchar (50)

@ newDay varchar (50)

@ oldDay datetime

@ partFunName varchar (50)

@ schemeName varchar (50)

@ sqlstr varchar (1000)

@ sql1 varchar (4000)

-- set @ tableName='DYDB'

Set @ newDay=CONVERT (varchar (10), DATEADD (mm, DATEDIFF (mm,0,@inputdate), 0), 23)-CONVERT (varchar (100), @ inputdate, 23)-23: by day

Set @ oldDay=cast (CONVERT (varchar (10), DATEADD (mm, DATEDIFF (mm,0,@inputdate)-1,0), 112) as datetime)

Set @ newNameStr=left (Replace (Replace (@ newDay,':','_'),'-','_'), 7)

Set @ fileGroupName=N'G'+@newNameStr

Set @ ndfName=N'F'+@newNameStr+''

Set @ fullPath=N'F:\\ SQLData\\ ecodata\'+ @ ndfName+'.ndf'

Set @ partFunName=N'pf_Time'

Set @ schemeName=N'ps_Time'

-- print @ fullPath

-- print @ fileGroupName

-- print @ ndfName

-- create filegroup

If exists (select * from sys.filegroups where name=@fileGroupName)

Begin

Print 'filegroup exists, no need to add'

End

Else

Begin

Exec ('ALTER DATABASE' + @ tableName+' ADD FILEGROUP ['+ @ fileGroupName+']')

-- print 'exec' + ('ALTER DATABASE' + @ tableName+' ADD FILEGROUP ['+ @ fileGroupName+']')

Print 'add filegroup'

If exists (select * from sys.partition_schemes where name = @ schemeName)

Begin

Exec ('alter partition scheme' + @ schemeName+' next used ['+ @ fileGroupName+']')

-- print 'exec' + ('alter partition scheme' + @ schemeName+' next used ['+ @ fileGroupName+']')

Print 'modify Partition Scheme'

End

Print 'exec' + ('alter partition scheme' + @ schemeName+' next used ['+ @ fileGroupName+']')

Print 'modify Partition Scheme'

If exists (select * from sys.partition_range_values where function_id= (select function_id from

Sys.partition_functions where name = @ partFunName) and value=@oldDay)

Begin

Exec ('alter partition function' + @ partFunName+' () split range (''+ @ newDay+''')')

-- print 'exec' + ('alter partition function' + @ partFunName+' () split range (''+ @ newDay+''')')

Print 'modify partition function'

End

End

-- create NDF file

If exists (select * from sys.database_files where [state] = 0 and (name=@ndfName or physical_name=@fullPath))

Begin

Print 'ndf file exists, no need to add'

End

Else

Begin

Exec ('ALTER DATABASE' + @ tableName+' ADD FILE (NAME ='+ @ ndfName+',FILENAME =''+ @ fullPath+''') TO FILEGROUP ['+ @ fileGroupName+']')

Print 'ALTER DATABASE' + @ tableName+' ADD FILE (NAME ='+ @ ndfName+',FILENAME =''+ @ fullPath+''') TO FILEGROUP ['+ @ fileGroupName+']'

Print 'newly created ndf File'

End

-- / *-the above filegroups and physical files that create the database-* /

End

-Partition function

-- if exists (select * from sys.partition_functions where name = @ partFunName)

-- begin

-- print 'modify here needs to be performed before modifying the partition function'

-- end

-- else

-- begin

-- exec ('CREATE PARTITION FUNCTION' + @ partFunName+' (DateTime) AS RANGE RIGHT FOR VALUES (''+ @ newDay+''')')

-print 'CREATE PARTITION FUNCTION' + @ partFunName+' (DateTime) AS RANGE RIGHT FOR VALUES (''+ @ newDay+''')'

-- print 'newly created partition function'

-- end

-Partition scheme

-- if exists (select * from sys.partition_schemes where name = @ schemeName)

-- begin

-- print 'changes here need to be performed before modifying the partition scheme'

-- end

-- else

-- begin

-- exec ('CREATE PARTITION SCHEME' + @ schemeName+' AS PARTITION'+ @ partFunName+' TO ('PRIMARY'','''+@fileGroupName+''')')

-print ('CREATE PARTITION SCHEME' + @ schemeName+' AS PARTITION'+ @ partFunName+' TO ('PRIMARY'','''+@fileGroupName+''')')

-- print 'newly created Partition Scheme'

two。 Add job

Click (here) to collapse or open

Declare @ date date

Set @ date= DATEADD (mm,1,getdate ())

Print @ date

Exec sp_maintain_partion_fg 'ecodata',@date
