How to fetch the row count for all tables in a SQL SERVER database

I am searching for a SQL Script that can be used to determine if there is any data (i.e. row count) in any of the tables of a given database.

The idea is to re-incarnate the database in case there are any rows existing (in any of the database).

The database being spoken of is Microsoft SQL SERVER.

Could someone suggest a sample script?

Answer

The following SQL will get you the row count of all tables in a database:

CREATE TABLE #counts
(
    table_name varchar(255),
    row_count int
)

EXEC sp_MSForEachTable @command1='INSERT #counts (table_name, row_count) SELECT ''?'', COUNT(*) FROM ?'
SELECT table_name, row_count FROM #counts ORDER BY table_name, row_count DESC
DROP TABLE #counts

The output will be a list of tables and their row counts.

If you just want the total row count across the whole database, appending:

SELECT SUM(row_count) AS total_row_count FROM #counts

will get you a single value for the total number of rows in the whole database.
