Implementing date_sub() function with intervals with jOOQ
java, jooq, mysql, sql
Solution
The solution:
Being slightly biased towards the Oracle database, jOOQ implements adding / subtracting day intervals simply by using:
// Java
DSL.currentTimestamp().sub(1);
The above renders:
-- Oracle
sysdate - 1
-- MySQL
date_add(current_timestamp(), interval -1 day)
Of course, you can also access the `date_add()` function directly, if you prefer that:
// Java
DSL.dateAdd(DSL.currentTimestamp(), -1);
Some documentation:
- The manual's section about date time arithmetic
- The manual's section about interval data types
- `Field.add()` Javadoc
- `DSL.dateAdd()` Javadoc
Problem
I've been dealing with this since yestertay. The thing is I am migrating my queries to jOOQ and I got stuck when I tried to implement this part: ``` select * from table where condition1 and date1 >= date_sub(now(), interval 1 days) ``` Specifically this part of the condition: date_sub(now(), interval 1 days) with jOOQ. So my questions are: Which functions should I use from jOOQ to represent date_sub? How do I implement interval X days with jOOQ? To clarify, the dates are of the type Timestamp Thanks in advance!
