A few days ago to write a program need to use the database, downloaded a use, there have been a lot of small problems (blame my 32bit do not make up the notebook), there are problems do not fear, at least prove that we are thinking about solutions.

When IDENTITY_INSERT is set to OFF, you cannot insert an explicit value into the identity column in table ' #TT '.I was in SQL Server to write the stored procedure encountered this error, then thought: how the temporary table has a primary key, I also did not set the primary key.Then I worked with my colleagues to debug, and finally found out. The reason is that

In SQL Server, the identity column is often used. This self-increasing field operation is indeed more convenient. But it sometimes brings some trouble. When all the records in the table are deleted, but the value of the ID column is getting bigger and bigger, if it is not reset, it will continue to grow endlessly. A

So, I mean to want to get the self-increment domain value of a, the result is the self-increment domain value of B, a BUG with the birth, do not have to affect the whole system of data confusion.Therefore, for this situation, we recommend that you use the @ @

The Identity identity column is often used in SQL Server, and this growing field is indeed convenient to operate. But sometimes it can bring some trouble. Example one: When some data is deleted from the table, the number from the growth column is no longer a line sequence. This time we can use the following solutions

Some records may be deleted when we use the database. Therefore, the identifiers in the data table may not start from 1 or intermittently. How can we reset and arrange it? SQL Server IDs are often used to increase by itself, that is, the identification column to act as the primary key of a table. There are two concepts to be clarified: 1. ID column:Use the
