We can write a stored procedure for identifying duplicate rows/XML nodes and delete them and execute that stored procedure The reference table/reference field with a valid key and then go for delete.

If it is used as a reference key thenĪ referential integrity error will be raised and delete operation becomes complex. If you face that situation then first you need to update If it is late then that duplicate row might be used as a reference row (foreign key). When to Delete?ĭuplicate rows try to identify and delete as early as possible. XML node in the data field (XML type) in the table.

To accurately visualize the problem and solution we create a sample table named MyTestTable2 withĬopy Code select id, data from MyTestTable2 It is equally importantĪs identifying and cleaning-up duplicate rows from the table, duplicate nodes from an XML field should be identified and cleaned-up for dataĪccuracy and to have methods to handle various exceptions. The XML field duplicate nodes might be created for various reasons. Data need to validate against any fixed schema.Dynamic data with schema is defined at runtime.Store multiple fields value to a single field.There are many reasons we should use the XML type field That means each group only keepsĪ row whose id is 1, the remaining ones will be deleted.ĭuplicate XML node Identification and Delete The generated rowid starts from 1 for each group. The The virtual field Rowid is generated group wise using the row_number function with id, name, DateOfBith fields treated as a group. Select row_number() over ( partition by id,Name,ĭateOfBirth order by id asc) as rowid, Id, Name, DateOfBirth Two duplicate rows are found then, what will happen? The query will delete So the delete query simply deletes the next row.

In our sample, rows 2Īnd 4 each have two rows. Please wait! The story is not finished yet. We use CTE for executing the delete statement based on the virtual field and clean up duplicate rows from So we will not execute the delete statement directly from the table based on that field. The rowid field is actually virtual and no physical existence So we create a dynamic unique field using The table has no unique field like a primary key by which we can identify each row. Group by id, Name, DateOfBirth having count(*) > 1) Īfter execution of the above query, the output is: Select row_number() over( order by id asc) as rowid, Id, Name, DateOfBirthĭELETE FROM cte WHERE rowid in ( select max(rowid) from cte My table structure consists of three fields:

The database table I create a sample table and rows, insert those rows to that table, and execute Identifying unique and duplicate rows from Data-entry operation enters duplicate rows.Re-structure/reorganize database, and time duplicate rows may created.Importing data from other databases, the source database contains duplicate rows.Besides that there areĪ few scenarios that cause creating duplicate rows:

Duplicate rowsĪre created easily when tables have no primary/unique key, no proper data validation,Īnd when business logic changes but data correction of existing data is not properly completed.

Nobody creates duplicate rows intentionally in a database. Try to understand the basic part of duplicate rows/XML-node issues and solutions so that in different scenarios It is difficult to cover all the scenarios in a single article and provide solutions. In real life, there are various unique scenarios that raise and handle all those with various techniques. I also cover duplicate XML nodes inside XML type fields with In this article I explain how can we identify duplicate rows from the database table and clean-up them. Everyone knows duplicate rows create so many problems: documents, such as PDF, DOC, DOCX, DOCM, XLS, XLSX, XLSM, RTF, TXT, HTML, HTM and any type of images files JPG, JPEG, BMP, GIF, TIFF, TIF, PNG, JP2, J2K, PCX.
