Hi all,
I have a 3 table  explained in below
 
table1 contains below columns 
 
     
         
             | id | Currency Symbol | Currency Name | 
         
             | 1 | $ | dollor | 
     
 
 
Table 2 contains below columns
     
         
             | id | Project | CurrencyId | 
         
             | 1 | Project#1 | 1 | 
     
 
 
Table 3 contains below columns
     
         
             | id | Item details | projectId | Currencyid | 
         
             | 1 | CPU | 1 | 1 | 
     
 
 
table 1 refers currency master 
Table 2 refers project details
table 3 refers Item related for projects
i need to write a trigger when project table currency id changes(update) that reflects Item related for project table 
 
Example:
If project table currency ID updates to 2 at that time trigger need to be generated and update the Itemrelated projects table currency id column
