SQL SERVER example with checkbox - sql

Question

Need your help with checkboxes.
Here is my code:
CREATE PROCEDURE stad_list
#inp_location_code numeric (3,0) = -1
#inp_item_code_bgn numeric (5,0) = -1
#inp_item_code_end numeric (5,0) = -1
#inp_shipped numeric (2,0) = 0, --checkbox, if it is checked then returns the items in table which were shipped (value in table is 1)
#inp_check numeric (2,0) = 0, --checkbox, if it is checked then returns data which is still in process of checking for availability in warehouse (value in table is 0)
#inp_not_ship numeric(2,0) = 0 --checkbox, if it is checked then returns data which had not been shipped during some problems (valuein table is 2)
AS
BEGIN
SET NOCOUNT ON;
DECLARE #SELECT as varchar (3000) = ''
DECLARE #WHERE as varchar (1000) = ''
IF (#inp_location_code != -1)
SET #WHERE = #WHERE + ' WHERE [dbo].item.location =' + CONVERT(varchar,#inp_location_code)
IF (#inp_item_code_bgn != -1)
SET #WHERE = #WHERE + ' AND [dbo].item.code>=' + CONVERT(varchar, #inp_item_code_bgn)
IF (#inp_item_code_end != -1)
SET #WHERE = #WHERE + ' AND [dbo].item.code<=' + CONVERT(varchar, #inp_item_code_end)
IF (#inp_shipped = 1)
SET #WHERE = #WHERE + ' AND [dbo].item.ship = 1'
IF (#inp_check = 1)
SET #WHERE = #WHERE + ' AND [dbo].item.ship = 0'
IF (#inp_not_ship = 1)
SET #WHERE = #WHERE + ' AND [dbo].item.ship = 2'
SET #SELECT = #SELECT + '
SELECT
[dbo].item.name as ''NAME'',
[dbo].item.location as ''LOCATION'',
[dbo].item.code as ''CODE'',
[dbo].item.ship as ''STATUS''
FROM [dbo].item '
+ #WHERE
EXEC (#SELECT)
RETURN ##ROWCOUNT
END
It works fine when i am checking only one check box, but cant get any data while 2 of it are checked. So what to do in case when i want to check two check boxes? Any suggestions?
here is my table
Id Item_code Item_name Item_location Item_ship
1 14789 Juice Tokyo 0
2 14785 Boots Tokyo 2
3 98744 Hat Osaka 0
4 36987 Socks Kyoto 1
And there is three checkboxes
Shipped
Checking
Not shipped
If i check shipped then output will be like this:
Id Item_code Item_name Item_location Item_ship
4 36987 Socks Kyoto 1
but i want to do so for ex. when i check Shipped and Checking then the output will be:
Id Item_code Item_name Item_location Item_ship
1 14789 Juice Tokyo 0
3 98744 Hat Osaka 0
4 36987 Socks Kyoto 1

Answer 1

Use temp table as table of parameters
IF (#inp_shipped = 1) OR (#inp_check = 1) OR (#inp_not_ship = 1)
BEGIN
IF OBJECT_ID('tempdb.dbo.#Parameters') IS NOT NULL DROP TABLE dbo.#Parameters
SELECT *
INTO #Parameters
FROM (
SELECT CASE WHEN #inp_shipped = 1 THEN 1 END AS Ship
UNION ALL
SELECT CASE WHEN #inp_check = 1 THEN 0 END
UNION ALL
SELECT CASE WHEN #inp_not_ship = 1 THEN 2 END
) p
WHERE p.Ship IS NOT NULL
SET #WHERE = #WHERE + ' AND [dbo].item.ship IN (SELECT ship FROM #Parameters)'
END
For better performance(made ​​to use index seek operation) if you have an index on the ship column, need to create an index on a temporary table:
CREATE INDEX x ON #Parameters(ship)

You could combine you options into this kind of construction:
declare #orcheck varchar(255)
set #orcheck = 'AND 1=2 ('
IF (#inp_shipped = 1)
SET #orcheck = #orcheck + ' OR [dbo].item.ship = 1'
IF (#inp_check = 1)
SET #orcheck = #orcheck + ' OR [dbo].item.ship = 0'
IF (#inp_not_ship = 1)
SET #orcheck = #orcheck + ' OR [dbo].item.ship = 2'
set #orcheck = #orcheck + ')'
This way, when you have all 3 checkboxes selected, the WHERE clause would look like this:
AND (1=2
OR [dbo].item.ship = 1
OR [dbo].item.ship = 0
OR [dbo].item.ship = 2
)
And when nothing is select, it would be:
AND (1=2
)
Which is what you expect, I believe.
