How can I get row count values in MySQL as @@ROWCOUNT
does in mssql?
To get the count of all the records in MySQL tables, we can use TABLE_ROWS with aggregate function SUM. The syntax is as follows. mysql> SELECT SUM(TABLE_ROWS) ->FROM INFORMATION_SCHEMA.
Row_NUMBER() included from MySQL version 8.0. It is a type of window function. This can be used to assign a sequence number for rows. To understand, create a table with the help of CREATE pcommand −
SQL Server @@ROWCOUNT is a system variable that is used to return the number of rows that are affected by the last executed statement in the batch.
The SQL COUNT() function returns the number of rows in a table satisfying the criteria specified in the WHERE clause. It sets the number of rows or non NULL column values. COUNT() returns 0 if there were no matching rows. The above syntax is the general SQL 2003 ANSI standard syntax.
For SELECTs you can use the FOUND_ROWS
construct (documented here):
SELECT SQL_CALC_FOUND_ROWS something FROM your_table WHERE whatever; SELECT FOUND_ROWS( ) ;
which will return the number of rows in the last SELECT
query (or if the first query has a LIMIT
clause, it returns the number of rows there would've been without the LIMIT
).
For UPDATE
/DELETE
/INSERT
, it's the ROW_COUNT construct
INSERT INTO your_table VALUES (1,2,3); SELECT ROW_COUNT();
which will return the number of affected rows.
mysql> SELECT SQL_CALC_FOUND_ROWS * FROM tbl_name -> WHERE id > 100 LIMIT 10; mysql> SELECT FOUND_ROWS();
