Outdated statistics can make the SQL server choose a non-optimal execution plan causing undesirable slow response times for certain queries.

*Warning: Irreparable database damage can occur. This procedure should only be performed by users familiar with SQL Server Management Studio. Databases should be backed up prior to performing this procedure.*

To identify tables within the database which have outdated statistics, the following query can be used.

SELECT OBJECT_NAME(id) AS Table ,st.[name] AS Tnaam,,
              STATS_DATE(id, indid) AS DateLastUpdate,rowmodctr rowsModifiedSinceLastUpdate
FROM sys.sysindexes AS si
INNER JOIN sys.[tables] AS st ON si.[id] = st.[object_id]
INNER JOIN sys.schemas AS ss ON st.[schema_id] = [ss].[schema_id]
AND rowmodctr>10
ORDER BY[rowmodctr] DESC

Once you have identified tables with outdated statistics, the UPDATE STATISTICS  statement can be used to
bring the statistics back up to date.
