The ON DUPLICATE KEY UPDATE clause is used andīe performed instead, the statement requires theīe updated. See Section 13.2.5.3, “INSERT DELAYED Statement”, Rows to be updated if a row to be inserted would cause a duplicate ON DUPLICATE KEY UPDATE clause enables existing SELECT form inserts rows selected from another table INSERT įorms of the statement insert rows based on explicitly specified ON DUPLICATE KEY UPDATE Statement 13.2.5.3 INSERT DELAYED Statement INSERT Here in the example above, we have inserted the values in table ‘dummy1’, having the same structure as table ‘dummy’, with a condition to insert only that row where ‘id = 1’.13.2.5.1 INSERT. mysql> Insert into dummy1(id,name)select id, name from dummy Where id =1

how we can use WHERE clause with INSERT INTO statement. If we want to insert in a table whose structure is same as another table then in the following example it has been demonstrated that how we can have conditional insert i.e. If the condition is true MySQL insert the row into table otherwise not. In the example above, we have created a table ‘testing’ and for inserting rows into it we have used dummy table dual with a condition. Mysql> Insert into testing (id,item_name)Select 1,'Book' From Dual Where 1=1 The syntax can be as follows − INSERT INTO table_name(column1,column2,column3,…) Select value1,value2,value3,… From dual WHERE Example mysql> Create table testing(id int, item_name varchar(10)) In this case, we insert the value from dummy table along with some conditions. It can be done with following ways − With the help of dummy table WHERE clause with INSERT INTO command in the case of new row insertion.
