Use COUNT() for this. Let us first create a table −mysql> create table DemoTable ( StudentFirstName varchar(20) ); Query OK, 0 rows affected (0.53 sec)Insert records in the table using insert command −mysql> insert into DemoTable values('Larry'); Query OK, 1 row affected (0.13 sec) mysql> insert into DemoTable values('John'); Query OK, 1 row affected (0.13 sec) mysql> insert into DemoTable values('Larry'); Query OK, 1 row affected (0.10 sec) mysql> insert into DemoTable values('David'); Query OK, 1 row affected (0.16 sec) mysql> insert into DemoTable values('Bob'); Query OK, 1 row affected (0.12 sec) mysql> insert into DemoTable values('Larry'); ...
Read More8085 program to print the table of input integer
In this program we will see how to generate table of an integer.Problem StatementWrite 8085 Assembly language program to generate a table of input integer. The number is stored at F050, and the table will be stored at F051 onwards.DiscussionTable generation is basically the multiplication table creation. We are taking the number and storing it to B. And initialize the counter as 0A (10 in decimal). In each step we are adding B with A and store value of A into memory, and decrease the counter by 1. These steps will repeat until the counter become 0.InputAddressData……F0504…… Flow Diagram ProgramAddressHEX CodesLabelsMnemonicsCommentsF00021, 50 ...

Here we will see how to find sum of two array elements and store result into memory.Problem StatementWrite 8086 Assembly language program to find summation of two arrays stored at 501 onwards and 601 onwards. The size of array is stored at location 500. After calculating the sum results are store result at 501 onwards.DiscussionTo solve this problem, we are taking elements from first array using source register SI, and second array using destination register DI. Repeatedly take elements from SI to AL, then add with the content of DI, and store again into SI address. Thus it is solved.InputAddressData……500055012C5020B5037D5042550521……601BA6024560369604CA60595…… Flow ...

Read More8259 PIC Microprocessor
The 8259 is known as the Programmable Interrupt Controller (PIC) microprocessor. In 8085 and 8086 there are five hardware interrupts and two hardware interrupts respectively. Bu adding 8259, we can increase the interrupt handling capability. This chip combines the multi-interrupt input source to single interrupt output. This provides 8-interrupts from IR0 to IR7. Let us see some features of this microprocessor.This chip is designed for 8085 and 8086.It can be programmed either in edge triggered, or in level triggered modeWe can mask individual bits of Interrupt Request Register.By cascading 8259 chips, we can increase interrupts up to 64 interrupt linesClock ...
