![]() The result is count column with number as single. If you are displaying records of a table then at the same time you can display number of records. To get the total number of rows present in MySQL table, run the query SELECT COUNT() FROM tablename. Here are the sql dump of product tables Showing Number of records while displaying records using select query and PHP MySQLI SELECT product, count(product_sale.product_id) as no FROM `product` left Join product_sale on product_sale.product_id=product.product_id group by product.product_id In above case there is no information about the products for which there is no record available in our sales table.īy Left join of tables. We will get the number of records by linking these two tables.īy using where condition SELECT product, count(product_sale.product_id) as no FROM `product`, product_sale where product_sale.product_id=product.product_id group by product.product_id We have two tables, one is storing products (table name product) and other one is storing sales record ( table name sale). We will use if condition checking to create a grid view.ĬOUNT(if(class='Three',1,NULL)) as THREE,ĬOUNT(if(class='Seven',1,NULL)) as SEVEN,ĬOUNT(if(class='Eight',1,NULL)) as EIGHT, WHERE DATE_PL BETWEEN '$dt1' AND '$dt2' Download the SQL dump of the above student table Creating grid view by showing rows as columns SELECT COUNT(S_NO) AS no_tickets FROM main_table This query will return the number of records found between two date ranges. Here is the code to change the date format and the query. ![]() We will keep two variables as $dt1 and $dt2 with two dates. Records between two date ranges ( PHP Script ) SELECT COUNT(id) AS total_records FROM student Counting number of distinct ( unique ) records SELECT COUNT( DISTINCT class ) FROM student tables: The tables that you wish to retrieve records from. So if we apply count to this id filed then it will more efficient. This is the column or expression whose non-null values will be counted. In our student table we have id field which is unique and auto incremented. Is there any way to get the exact row count of all tables in Postgres in fast way Count () seems to run very slowly for larger tables. In above query we have used all the columns to find out the total number of records ( by using count(*) ). Using BETWEEN SELECT count(*) FROM `student` WHERE class='Four' SELECT count(*) FROM `student` WHERE class='Four' and mark >60 We can count the records in different combinations like finding out the number of students of class four who has got more than 60 mark. ![]() GROUP BY clause to display totals of each class. Require to display total of each class in a table so here we have to use Here since we areĭisplaying only one count for a fixed class so we can use this way. This will return the count of students in class four only. Related Tutorial GROUP BY count Number of rows mysql table
