Collection: if it represents a type, it is written as array. If it is a collection, it is written as list

Item: is a variable name. You can name it yourself

2. In this way, multiple SQL statements can be executed at one time

3. Overall batch update

1. Prefix, suffix means adding content before or after the part of the trim label package 2 If there are prefixoverrides at the same time, suffixoverrides means that the content in overrides will be overwritten with prefix and suffix. 3. If there are only prefixoverrides, suffixoverrides means to delete the content specified by the beginning or end of xxxoverrides.
