Single sql query to select a record from parent table only if all it's records in child table has valuesReplacement for Nested SELECT statements for every row in SELECT clauseTroubleshooting extremely long running query (SQL Server 2012)split a row into multiple rows in sql server according to a specific columnReplacing isnull condition in where clauseSorting a Date Column in Microsoft SQL Server Management StudioReplacing NULL values in LEFT JOIN with MAX functionUpdate columns with different values depending upon different condition of rows from scd2 type tableStrange query plan when using OR in JOIN clause - Constant scan for every row in tableExclusionary Left Joins
I use a UNION ALL query and it outputs 2 rows for the same date. I want to output only 1 row like the second picture.
Do i have to use IIF, CASE or else command?
The date, time_in, time_out fields are output from other table (main_table) and then i use a left join with the following UNION ALL query.
(select date, time_in, time_out,leave_start,leave_end,leave_type_id, leave_type_descr
from table1
union all
select date, time_in, time_out,null,null,leave_type_id, leave_type_descr
from table2)
