ORACLE IIF Statement
(3 answers)
Closed 2 years ago.
How do we write IIF condition in Oracle.
IIF(ItemType = '-1' , (Select CAST(CAST(ConfigXml as XML).query('data(/configurations/config/itemtypeid)') as nvarchar (64)) from EmailCaptureConfig where OwnerID = 142 and ConfigID = 1), ActionObjecttype) as ActionObject
I need to convert the above IIF into ORACLE but am unable to do so. How do we go forward with this.
Similar to this:
decode(ItemType, '-1' , (Select CAST(CAST(ConfigXml as XML).query('data(/configurations/config/itemtypeid)') as nvarchar (64)) from EmailCaptureConfig where OwnerID = 142 and ConfigID = 1), ActionObjecttype) as ActionObject
Obviously the xml datatype works differently in Oracle than Microsoft.

I'm trying to write a query, that selects a number of values. I only want it to select one of the values if it isn't null.
I'm trying to use a case when but it is erroring.
SELECT pick_no,
pd.product,
from_warehouse,
to_warehouse,
qty_pick,
qty_check,
qty_picked,
qty_checked,
long_description,
ROUND(qty_pick / stk.pallet_unit_qty, 2) as [PalletQty],
ph.date_picking,
stk.bin_no,
CASE WHEN qty_picked <> null
THEN ROUND(qty_picked / stk.pallet_unit_qty, 2) as [pltCheck]
ELSE '0' END
FROM
Null is a tricky beast, you can't use equality operands on it. Also your else clause was returning a CHAR when the first clause returns a FLOAT :
CASE WHEN qty_picked IS NOT NULL
THEN ROUND(qty_picked / stk.pallet_unit_qty, 2) as [pltCheck]
ELSE 0 END
A simpler way to achieve your goal is to use COALESCE :
COALESCE(ROUND(qty_picked / stk.pallet_unit_qty, 2),0) as [pltCheck]

Using simple query , I can do something like

shopping
fishing
coding

shopping, fishing, coding
for ref-- Can I concatenate multiple MySQL rows into one field?
I want to do this in sql server ??
SQL Server doesn't have great support for aggregate string concatenation. But you can do:
select stuff((select ', ' + hobbies
from peoples_hobbies
where person_id = 5
for xml path ('')
), 1, 2, '') as hobbies;

I get this from a table John Doe.
What is the best way to split this to have into two variable this :
lastName = 'Doe';
firstName = 'John';
I guess this should work :
SELECT SUBSTR(NameColumn, 1, INSTR(NameColumn,' ',1)) AS firstName,
SUBSTR(NameColumn, INSTR(NameColumn,' ',1)+1) FROM tablName

xmldescr.value('/Descr[1]/desc[1]','varchar(100)') AS Descr1,
xmldescr.value('/Descr[1]/desc[2]','varchar(100)') AS Descr2,
xmldescr.value('/Descr[1]/desc[3]','varchar(100)') AS Descr3
