Updating partition key column

11 Jan

For example, if I have a table that has a partition key: Can I move a row from the first partition to the third partition by changing the Sample ID from 1 to (say) 500,000?Note: I'm tagging this as both sql server 20, since they both support partitioning. USE [Test] GO CREATE TABLE [IDRanges]( [ID] [int] NOT NULL ) GO CREATE PARTITION FUNCTION IDRange1 (int) AS RANGE LEFT FOR VALUES (10) ; GO --Add one record to each partition INSERT INTO IDRanges ([ID]) VALUES (17) INSERT INTO IDRanges ([ID]) VALUES (7) GO --Verify records in partition SELECT $PARTITION.In order to partition the table, you also have to create file groups and a partitioning scheme that uses the partitioning function to assign function results to file groups.All, I am updating the table based on the leading partition key and i got the error message. you're not just updating a single column and leaving the row in place, you're actually moving the row to a new block.Hi, When I am trying to execute an update statement where i am tring to update date values emp_det from 11-oct-2010 to 12-nov-2010.

See the partitioning function just tells you what the partitioning function says. You can set up a partitioning function and run it without actually partitioning a table, as has been demonstrated here already. One of the relatively newer features in Oracle concerns the moving of rows. An early use of row movement was highlighted in Oracle8i, and row movement then, as well as now, applied to moving rows in a partitioned table.Why would a row move and who or what controls that movement? With newer releases of the Oracle RDBMS, where else does row movement come into play, and are there any gotcha's with respect to row movement operations?Oracle throws an error : ORA-14402 updating partition key column would cause a partition change I think that this is because emp_det is a partitioning key of a partitioned table.Oracle documentation says that "UPDATE will fail if you change a value in the column that would move the row to a different partition or subpartition, unless you enable row movement" .IDRange1([ID]) AS Partition, COUNT(*) AS [COUNT] FROM IDRanges GROUP BY $PARTITION.IDRange1([ID]) ORDER BY Partition ; GO --Move row between partitions UPDATE IDRanges SET [ID] = 8 WHERE [ID] = 17 GO --Verify records in partition SELECT $PARTITION.Or two offices in the same city (from different groups or business units within the same company) merge into one location?You could split the default partition and add the new location name.alter table t enable row movement; I did not understand what is meant by "enable row movement".I cannot drop the partitions and recreate it after updating the table and also i don't have proper priviliges for enale row movement syntax because of the lack of privileges.
