Read MoreHow to use user variables in MySQL LIKE clause?
Using the CONCAT() function, we can work with user variables in LIKE clause. The syntax is as follows.set @anyVariableName='anyValue'; select yourColumnName1, yourColumnName2, yourColumnName3, ...N from yourTableName whereyourColumnName like CONCAT('%', @anyVariableName, '%');To understand the above syntax, let us first create a table. The query to create a table is as follows.mysql> create table UserVariableInLike -> ( -> id int, -> Name varchar(100), -> Age int -> ); Query OK, 0 rows affected (0.83 sec)Insert records in the table using insert command. The query is as follows.mysql> insert into UserVariableInLike values(101, 'John', 23); Query OK, 1 row affected (0.23 sec) mysql> ...

Read MoreArchitecture of 8259
8259 Microprocessor is architected in a unique style. It can program by means of some interrupts conditions by means of level or interrupt level often called edge-triggered interrupt level. Masking is done to individual interrupt bits. As the number of 8259 increases interrupt pins up to 64 can be obtained. There are 3 registers 8259 contains along with one priority resolver(PR). They are as follows −Interrupt Request Register(IIR) − It stores the bits who requests the interrupt.Interrupt service register(ISR) − It stores the currently interrupt levels.Interrupt Mask Register(IMR) − Stores the interrupt levels to be masked.PriorityResolver(PR) − Set the priority of ...
Read MoreInstruction to complement Accumulator in 8085 Microprocessor
In 8085 Instruction set, logical type there is one complement instruction with the mnemonic CMA. It actually stands for “CoMplement the Accumulator”. It performs1's complement operation on the current contents of Accumulator, and the result is stored back in the Accumulator replacing its previous contents. It is to be noted that, there are no other instructions tocomplement any other register’s contents. Though it is a logicaltype of instruction, Flag bits are not affected by the execution of this instruction. It occupies only 1 Byte in memory. Mnemonics, OperandOpcode(in HEX)BytesCMA2F1Let us suppose that example, the initial content of Accumulator is AAH i.e. ...
Read MoreConditional call instructions in 8085 Microprocessor
In 8085 Instruction set, depending upon one of the flag bit values (excluding AC flag bit), the conditional call instructions will branch to a subroutine. The branch takes place based on the value of Cy flag, Z flag, P flag, or S flag. There is no call instruction based on the value of AC(Auxiliary Carry) flag bit. This is because generally, no one is interested in branching to a subroutine based on this flag bit value. The conditional call instructions are 3 Bytes in length, 1 Byte for the opcode, and another 2 Bytes for the subroutine address i.e.low-order Byte ...
