Query with Comparing Dates in SQL

IF OBJECT_ID( 'tempdb..#Members' ) IS NOT NULL DROP TABLE #Members; 

CREATE TABLE #Members (member_name varchar(10), member_date datetime); 

INSERT INTO #Members VALUES ('Java', '2021-11-09 11:16:10.496'); 
INSERT INTO #Members VALUES ('MySQL', '2021-11-10 00:00:00.000'); 
INSERT INTO #Members VALUES ('SQL SERVER', '2021-11-10 11:26:10.193' ); 
INSERT INTO #Members VALUES ('PostgreSQL', '2021-11-10 12:36:10.393'); 
INSERT INTO #Members VALUES ('Oracle', '2021-11-11 00:00:00.000');

Now, you need to write a query to get all members which are on ‘2021-11-10’? Right query, should return 3 rows containing dates starting with ‘2021-1-07’, as shown below:

'MySQL', '2021-11-10 00:00:00.000' 
'SQL SERVER', '2021-11-10 11:26:10.193' 
'PostgreSQL', '2021-11-10 12:36:10.393'
SELECT * FROM #Members WHERE member_date = '2021-11-10' member_name member_date MySQL 2021-11-10 00:00:00.000

Comparing dates with between clause

SELECT * FROM #Members 
WHERE member_date between '2021-11-10' and '2021-11-11' member_name member_date 

MySQL 2021-11-10 00:00:00.000 
SQL SERVER 2021-11-10 11:26:10.193 
PostgreSQL 2021-11-10 12:36:10.393 
Oracle 2021-11-11 00:00:00.000

Always Use >= and < to compare dates

SELECT * FROM #Members WHERE member_date >= '2021-11-10' and member_date < '2021-11-11' member_name member_date 

MySQL 2021-11-10 00:00:00.000 
SQL SERVER 2021-11-10 11:26:10.193 
PostgreSQL 2021-11-10 12:36:10.393

Example 1: Range: date format maybe vendor dependent

SELECT memberName, memberDesc FROM members WHERE createdDate >= '2021-06-01' and createdDate < '2021-06-02' 

Example 2: SQL-92 Cast: data type maybe vendor dependent.

SELECT memberName, memberDesc FROM members WHERE CAST(createdDate AS DATE) = '2021-06-01'

Example 3: MS SQL Convert: vendor dependent but other databases

SELECT memberName, memberDesc FROM members WHERE Convert(DATE, createdDate) = '2021-06-01'

Example 4: MySQL Date: vendor dependent but other databases

SELECT memberName, memberDesc FROM members WHERE Date(createdDate) = '2021-06-01'

Example 5: Oracle/Postgres Trunc: vendor dependent

SELECT memberName, memberDesc FROM members WHERE Trunc(createdDate) = '2021-06-01'
