What is 1 = 1 in oracle? For example:

1 = 1 is true, which is used in the where condition or loop statement,
Select * from table where 1 = 1: Query all data that meets 1 = 1. In this case, the where condition is equivalent
To put it bluntly, this statement is useless, but it is generally used for statement concatenation,
After where 1 = 1, you can concatenate and A = 'A' directly.
This eliminates the need to determine whether the where keyword exists and whether or not the and keyword needs to be added.
