Filter by Dates in SQL

Filter by Dates in SQL

If your dates column does not contain time information, you could get away with:

WHERE dates BETWEEN '20121211' and '20121213'

However, given your dates column is actually datetime, you want this

WHERE dates >= '20121211'
  AND dates < '20121214'  -- i.e. 00:00 of the next day

Another option for SQL Server 2008 onwards that retains SARGability (ability to use index for good performance) is:

WHERE CAST(dates as date) BETWEEN '20121211' and '20121213'

Note: always use ISO-8601 format YYYYMMDD with SQL Server for unambiguous date literals.

Filter data based on date in sql

Since you have not mentioned about any errors, if START_DATE and END_DATE are DATETIME data type, there is nothing wrong with your query. If you are not getting the correct records, Please check the data.

However your date format may trouble you in a different server. There are some good practices you could adhere to avoid such issues.

-Whenever date is used as a string, try to use it in ISO or ISO8601
format (ie 'yyyymmdd' or 'yyyy-mm-ddThh:mi:ss.mmm')

-Also avoid joining tables with WHERE Table1, Table2 which is old and
obsolete. JOINs are much better performed, neat and tidy.

You can change your query as follows;

SELECT DISTINCT T1.column1, T1.column2, T2.START_DATE, T2.END_DATE
FROM Table1 T1 JOIN Table2 T2 ON T1.column1 = T2.column2
WHERE (T2.START_DATE >= '20130115 10:58:58' AND 
       T2.END_DATE <= '20130118 10:58:58') 
ORDER BY T2.START_DATE DESC

How can I filter on date values?

80 years old or older.

This means that they were born earlier than current-date - 80 years. Your comparison is in the wrong direction:

sqlQuery(con, "SELECT *
              FROM People
              WHERE BirthDT <= '1941-02-11'")

Date filtering from past two weeks

You can compare the created_on column with an expression that calculates "two weeks before today":

un.created_on >= current_date - interval '2 weeks'

alternatively you can also subtract 14 days

un.created_on >= current_date - 14

How to filter date range from date - 2 weeks and date + 2 weeks

Try using the add_days() function:

WHERE t.VALID_FROM >= add_days('2020-11-26', -14) AND
      t.VALID_TO <= add_days('2020-11-26', -14)

properly filtering Dates in SQL

If touchedwhen is a date/time, then use something like this:

(CV3OrderTaskOccurrence.TouchedWhen >= '2020-01-01' and
 CV3OrderTaskOccurrence.TouchedWhen < '2021-01-01' 
)

Actually, this will also work if the value is stored as a string, but I strongly recommend that you store values using correct data types.

How do I filter by date in SQL?

You must use single quotes in where clause, double quotes are used in column identifier or reserved words.

select *
from table_name
where date_col = '2015-04-02'
limit 5
