In the above example, the IF function is used to check if the age is less than 18 OR the grade is less than 60. If any of these conditions is true, the result will be set as “fail”; otherwise, it will be set as “pass”. Using Multiple Conditions with AND Similarly, you can ...

MySQL IF() with Multiple Conditions Suppose you have the following problem – Check if 5 is greater than 2 and 2 is greater than 1. If both conditions are true, display “Yes!”, else display “No.” Now we have two conditions here. To join two conditions, we can use the keywordsAND...
in both cases those are ranges, but in the case when it is A in (0,1) – list, MySQL realizes that it is not range and replaces it by multiple equality conditions. In this case, MySQL will use the index. So one needs to make a right decision – either to ...
. Then it can be used multiple conditions. Here some options: Working with two conditions Using AND with two or more conditions the query can be narrowed to meet your needs. SELECT*FROMtableWHEREcolumn1='var1'ANDcolumn2='var2'; Only when the two conditions are met the row is stracted ...

Condition information, such as the error code and message. If a statement raises multiple conditions, this part of the diagnostics area has a condition area for each one. If a statement raises no conditions, this part of the diagnostics area is empty. ...

An object can be saved using multiple # contiguous pages, but pages can't be shared between different objects. # So if your page is too big, small objects swapped out on disk will waste # a lot of space. If you page is too small, there is less space in the swap # file (assuming...
