Pinal Dave is a SQL Server Performance Tuning Expert and an independent consultant. This is an iterative approach which captures the row count for each of the individual tables, puts them together and displays the results for all the tables. You can declare sql cursor using DECLARE cursorname CURSOR syntax.. Infact the 2nd approach presented above is on these lines with a couple additional filters. VIEW SERVER STATE or VIEW DATABASE STATE permissions, http://msdn.microsoft.com/en-us/library/ms190283.aspx, http://msdn.microsoft.com/en-us/library/ms187997.aspx, Run same command on all SQL Server databases without cursors, Searching and finding a string value in all columns in a SQL Server table, List columns and attributes for every table in a SQL Server database, Fix SQL Server CTE Maximum Recursion Exhausted Error, SQL Server Common Table Expressions (CTE) usage and examples. Row count at SQL execution time: The "real" current row count, which requires that you actually issue SQL to count the rows in all of the tables (time consuming). The T-SQL query below uses the sys.partitions Catalog View to capture the row counts for all tables in a database. The below query simply fetches the record count per table irrespective of volume. He has authored 12 SQL Server database books, 35 Pluralsight courses and has written over 5200 articles on the database technology on his blog at a https://blog.sqlauthority.com. select s.schema_id,s.name schema_name,o.object_id,o.name object_name,c.column_id,c.name column_name, fk.name FK_name, i.name index_name, SUM(p.rows) row_count, GROUP BY s.schema_id,s.name ,o.object_id,o.name ,c.column_id,c.name , fk.name , i.name, select s.schema_id,s.name schema_name,o.object_id,o.name object_name,c.column_id,c.name column_name,i.object_id,i.index_id,i.name index_name, ic.index_column_id, fk.name FK_name, INNER JOIN sys.indexes i on i.object_id = o.object_id, INNER JOIN sys.index_columns ic on o.object_id = ic.object_id and i.index_id = ic.Index_id and c.column_id = ic.column_id, LEFT JOIN sys.foreign_key_columns fkc on fkc.parent_object_id = o.object_id and fkc.parent_column_id = c.column_id, LEFT JOIN sys.foreign_keys fk on fk.object_id = fkc.constraint_object_id, LEFT JOIN sys.key_constraints kc on kc.parent_object_id = o.object_id and i.index_id = kc.unique_index_id, order by s.name,o.name,c.column_id,i.name. Additional approach: use column rowcnt in sysindexes: select sum(rowcnt) from sysindexes where indid < 2. if you want to eliminate system tables, use this query: select sum(a.rowcnt) from sysindexes a join sys.tables b on a.id = b.object_id where a.indid < 2 and b.is_ms_shipped = 0. Below is sample output from AdventureWorksDW database. All tables and indexes in SQL Server contain at least one partition, whether or not they are explicitly partitioned. But what about tables where its not partitioned ? [object_id] = [Partitions]. Favorites Add to favorites. Count Rows In All Views: Unlike for tables, there is no way to query any DMV to get the row count. Your approach works well too! Based on your preferences mentioned above, I would suggest you use Approach# 4 mentioned above (ofcourse you need to change type = 'U' to type = 'V') with the following considerations in mind: what if I want to capture row counts off of SQL Views? Now we need to add the row totals together. We should avoid using this as this feature will be removed in future versions of SQL Server. ALL serves as the default. The T-SQL query below uses the sp_MSforeachtable system stored procedure to iterate through each of the tables to capture the row count for all the tables in a database. COUNT will always return an INT. There's a quick way to get row counts using SQL Server metadata. In this type of scenario, I don't see any much performance impact and Approach# 4 can be used here as well. Do I need to have a specific node selected in the Object Explorer? I modified sp_spaceused to return correct schema name. USE Northwind; SELECT TableName = o. name, Rows = max (i. rows) FROM sysobjects o ⦠+ ta.name TableName, SUM(pa.rows) RowCnt FROM sys.tables ta INNER JOIN sys.partitions pa ON pa.OBJECT_ID = ta.OBJECT_ID INNER JOIN sys.schemas sc ON ta.schema_id = sc.schema_id WHERE ta.is_ms_shipped = 0 AND pa.index_id IN (1,0) GROUP BY sc.name, ta.name ORDER BY SUM(pa.rows) DESC Thanks to this article suggestions? In general, querying the Dynamic Management Views (DMVs), requires VIEW SERVER STATE or VIEW DATABASE STATE permissions based on the Dynamic Management View/Function which is being queried. To count all of the rows in real time, a simple SQL*Plus script will suffice: Try 'Import-Module SQLPS' if you get "A drive with the name 'SQLSERVER' does not exist" ). Download. sp_MSforeachtable is an undocumented system stored procedure which can be used to iterate through each of the tables in a database. To find the equivalent system view or views, see Mapping SQL Server 2000 System Tables to SQL Server 2005 System Views. What are the different approaches to get this information? Thanks for the help.� I found that this and other examples returned records where the column was in a compound index so I wrote this to only show FK columns that were not part of any index.� Also wrapped in foreachDB.� Comment the WHERE clause and HAVING to see all records. That provides row count, space used including index etc. In this post, we will learn about how to get all tables records count from the selected database. Along with 17+ years of hands-on experience, he holds a Masters of Science degree and a number of database certifications. [schema_id], INNER JOIN sys.partitions p ON p.object_id = o.object_id, INNER JOIN sys.indexes ip ON ip.object_id=o.object_id and p.index_id = ip.index_id and ip.is_primary_key=1, INNER JOIN sys.columns c on c.object_id = o.object_id, INNER JOIN sys.foreign_key_columns fkc on fkc.parent_object_id = o.object_id and fkc.parent_column_id = c.column_id, INNER JOIN sys.foreign_keys fk on fk.object_id = fkc.constraint_object_id, LEFT JOIN sys.index_columns ic on o.object_id = ic.object_id and c.column_id = ic.column_id, LEFT JOIN sys.indexes i on i.index_id = ic.Index_id and i.object_id = ic.object_id, order by s.name,o.name,c.column_id,fk.name'. It works flawlessly in my Python script that uses pyodbc module to query table record counts from SQL Server. See the below result screenshot that returns the above query. sp_MSforeachtable is an undocumented system stored procedure. SELECT sc.name + '.' In fact, it is a user stored procedure that was created by Jarlath OâGrady (https://www.linkedin.com/in/jarlathogrady/) back in the SQL Server 6.5 days. [rows]) AS [TotalRowCount] FROM sys.tables AS [Tables] JOIN sys.partitions AS [Partitions] ON [Tables]. Here we are using sys.objects and sys.partitions for getting the record count. The differences I see are storing the results in Temp Table instead of Table Variable, and use of sp_spaceused system stored procedure. Every table in SQL Server contains at least one partition (default partition) even if the table is not explicitly partitioned. In this tip we will see four different approaches to get the row counts from all the tables in a SQL Server database. (if you really want do to it the hard way - aka the not performant way - in SSIS, use a for each loop container and loop over the tables. Some names and products listed are the registered trademarks of their respective owners. Scope of rows: all tables in a database including tables without rows Ordered by number of rows descending, from largest to smallest (in terms of number of rows) Can i select all the record inserted/updated by last hour from all table from particular database. Along with 17+ years of hands-on experience, he holds a Masters of Science degree and a number of database certifications. SELECT DISTINCT OBJECT_NAME(ID),ID,ROWCNT FROM SYSINDEXES WHERE INDID < 2. By: Dattatrey Sindol | Updated: 2011-11-11 | Comments (31) | Related: More > Scripts. Here are a few ways of listing all the tables that exist in a database together with the number of rows they contain. In this post, we will learn how to get all table record counts from the selected database. You could add this into your query in @SQL: SELECT [Rows] = SUM(row_count) FROM sys.dm_db_partition_stats WHERE object_id=@YourObjectId AND (index_id=0 or index_id=1); I believe that would make the ⦠COUNT () returns 0 if there were no matching rows. *FIXED*, Row count was wrong, now I pull the value the primary key index only, select DB_NAME(),s.name schema_name,o.name object_name,c.name column_name, fk.name FK_name, i.name index_name, p.rows, INNER JOIN sys.objects o ON s.[schema_id] = o. I Reckon, the below query would do the trick. Thank you both for your feedback and additional information. The above options might all works well in case of tables partitioned / columns indexed. To get the number of rows in a single table we usually use SELECT COUNT(*) or SELECT COUNT_BIG(*). I found count(*) could really take a long time so I used: IF OBJECT_ID('tempdb..#sizeo') IS NOT NULL. For this example, set the top 10 rows to get only 10 table names and record counts. a column defined as SMALLINT â and SQL Server will use this index.
