sql My select statement

Hi,

I have a select statement that I want to filter out any null value but instead my query display the null value.

I just want to display the record if one of those field has a value otherwise don't.

select EditTime, AppID, AppName, MajorUpgradeCost, PlannedUpgradeYear, UpgradeStrategy, SoftwareVersion,
OldestVersionSupportedBySupplier, EmployeeName
 from EDIT_ApplicationDescription
 where MajorUpgradeCost != '' or PlannedUpgradeYear != '' or UpgradeStrategy != '' or SoftwareVersion != ''
 or OldestVersionSupportedBySupplier != '' or EmployeeName != ''
 order by EditTime desc

Open in new window



the output that I am getting is this:

EditTime	AppID	AppName	MajorUpgradeCost	PlannedUpgradeYear	UpgradeStrategy	SoftwareVersion	OldestVersionSupportedBySupplier	EmployeeName
58:43.0	52	test1 	NULL	NULL	NULL	NULL	NULL	NFOCO

Using functions on data might looks compact and neat, but it isn't great for performance as it can remove the ability to use indexes (making a query slower) see sargable

I recommend using IS NOT NULL it's easier to read in my view. Note for each field you would need your existing condition AND the IS NOT NULL condition within parentheses.
SELECT
      EditTime
    , AppID
    , AppName
    , MajorUpgradeCost
    , PlannedUpgradeYear
    , UpgradeStrategy
    , SoftwareVersion
    , OldestVersionSupportedBySupplier
    , EmployeeName
FROM EDIT_ApplicationDescription
WHERE (MajorUpgradeCost <> ''  AND MajorUpgradeCost IS NOT NULL)
OR (PlannedUpgradeYear <> ''  AND PlannedUpgradeYear IS NOT NULL)
OR (UpgradeStrategy <> '' AND UpgradeStrategy IS NOT NULL)
OR (SoftwareVersion <> ''  AND SoftwareVersion IS NOT NULL)
OR (OldestVersionSupportedBySupplier <> '' AND OldestVersionSupportedBySupplier IS NOT NULL)
OR (EmployeeName <> ''  AND EmployeeName IS NOT NULL)
ORDER BY EditTime DESC
;

I also prefer to use <> for not equal but != works of course.

use "MajorUpgradeCost is not null or ..."

or use this

coalesce(MajorUpgradeCost, '') != '' or ...

or add more code and make it ugly...

MajorUpgradeCost IS not NULL and MajorUpgradeCost != '' and...

I guess you should convert all "or" to "and" as well...

HainKurtSr. System AnalystCommented:
just read the question again :) you should use "or"

this should work

coalesce(MajorUpgradeCost, '') != '' or coalesce(PlannedUpgradeYear, '') != '' or ...

Is this about MsSql or MySQL? The former will not match nulls by default, do either you use MySQL or have unset the ANSI SQL NULL.
