At times, while working with SQL Server database, users may encounter sql server error 2570 which indicates the below error message:
The above error message can occur due to certain reasons. In this article we will discuss what is SQL Server error 2570 and also determine the various reasons for its occurrence.
SQL Server 2005 offers a new option i.e. data purity to the DBCC CHECKDB and DBCC CHECKTABLE commands. While executing certain DBCC commands with an enabled option, this command will execute "data purity" validations on every column of the table or tables in a database. These new check features must ensure that all values stored in the column is valid it means the value is not out of range with the data type of that column. The nature of validation test is generally depends upon the column's type.
In an earlier SQL server version, invalid or out-of-range data might be stored in it. There are following reasons which are responsible for generating 2570 error:
While running DBCC command (DBCC CHECKDB or DBCC CHECKTABLE) with this DATA_PURITY option is enabled (or the data purity checks were run automatically), and invalid data already exists in a single table checked by these DBCC commands. However, DBCC output contains the additional messages, which indicate reals problems with the database.
The SQL server error 2570 cannot be fixed by using any of the repair options. It will be impossible for DBCC to obtain what possible value should used to change the invalid value of the column. Thus, the column value must be updated manually.
Performing the manual updates, fisrt, users must have to find the row that has the following problems. There are two different ways to accomplish this:
Once users will find the correct row, a decision should be made on a new value that can be used to replace an existing invalid data value. To do the same, follow below points as such:
Note: You can also use T-SQL (Transact-SQL) Queries to find the Rows that have invalid Values.
SQL Server Error 2570 occurs due to the presence of invalid data within it. Along with this, all possible reasons of this error can be discussed by running such DBCC commands. In addition, we have already mentioned a manual solution to resolve this problem.
