| Hi there, I am building a simple trigger that is creating a future task when a current task is complete.All is good but I am having diffuclty with the primary key. The primary key (taskid) starts with _2 and then is 20 extra random number charaters. Any help with the SQL insert for a record to have random charaters is appreciated.thanks |

| SELECT REPLACE(STR(CAST(1000000000*RAND() AS INT), 12), ' ', '0') But still it is not recommended as Primary Key as though its random number, still could be duplicate.--------------------------http://connectsql.blogspot.com/ |

| SELECT REPLACE(STR(CAST(1000000000*RAND() AS INT), 12), ' ', '0') I have tried to use the above code in the insert command but it does not work.Basically the trigger is looking for a record that has been completed and re create it with a new start and due date and a new task ID. Can the above be modified? |
