Advantages of setting up automatic growth ID

Some of the advantages of setting up an automatic growth ID include:

• Simplify data insertion: Automatically grow IDs eliminate the need to manually enter IDs, thus simplifying the data insertion process.
• Ensure uniqueness: Automatically growing IDs automatically generate unique values, preventing duplicate IDs from causing data corruption.
• Optimized Performance: When using automatic growth IDs, the database can find data more efficiently because the IDs are always sorted in order.
• Easy to identify: Automatically growing IDs are easy to identify because they are usually continuous sequences of numbers.

Things to note

The following things to note when setting the automatic growth ID:

• Limit value: Ensure that the set automatic growth ID range is large enough to meet the growth needs of the table.
• Duplicate Value: Automatically increasing the ID may not prevent duplicate IDs if the "unique" constraint of the table allows duplicate values.
• Delete Data: When deleting data with an automatic growth ID, the ID will not be reused. This means that if the data is deleted and the data is inserted again, these newly inserted data will have a higher ID value.
