When building a table, the type defined in the sid field is guid.

There is no such data type in the database. You can't even build a table. How do you insert data?

Another problem is that if the guid is put into the varchar () type before the insert statement is executed, an exception message will definitely be reported.

change

Variable length string

value

'634294078577 187500'

Integer column overflowed when. Maximum integer value exceeded.

The data type of the lastmodifiedticks you defined is int, and the data you inserted has exceeded the integer digits.

The solution is to change the data type to varchar () or char ().
