How can I using something like if or case..when to combine the following code into one?
if #para = 'test'
begin
select * from Table A where status='A' and id in (select id from Table B)
end
else if #para = 'others'
begin
select * from Table A where status='A' and id in (select id from Table c)
end
like select * from Table A where id in if #para = XXX then (select id from Table B)
Thanks a lot.
Try this:
select *
from Table A
where (id in (select id from Table B) and #para = 'test')
OR
(id in (select id from Table c) and #para = 'others')
As you tagged stored procedure i made it as one ... try it like this
create procedure GetData (#para nvarchar(100))
as
begin
declare #sql nvarchar(max)
set #sql = case
when #para = 'test'
then
'Select * from TableA A
join TableB B on A.id = B.ID'
else -- if #para = 'others' goes into else
'Select * from TableA A
join TableB B on A.id = B.ID'
end
execute (#sql)
end

I have this table with 22 rows as above
I am getting a converted table as above
I created following procedure in order to get result table
ALTER PROCEDURE [dbo].[proc_YS_BAB_IR_Item]
#UserId int
AS
BEGIN TRAN
DECLARE #SqlQry NVARCHAR(MAX);
SET #SqlQry = N''
DECLARE #Cnt INT = 1, #EndCnt INT = 25,
#v_UserId INT = CAST(#UserId AS VARCHAR(MAX));
CREATE TABLE #TempColumns
(
Calculate_ItemIdentifier VARCHAR(MAX),
SeqOrder INT
)
WHILE #cnt <= #EndCnt
BEGIN
INSERT INTO #TempColumns
SELECT
'IR'+ CAST(#Cnt AS VARCHAR(MAX)),
#Cnt
SET #Cnt = #Cnt + 1;
END
DECLARE #DATA VARCHAR(10), #DATA1 VARCHAR(10) = '000000'
DECLARE #zero_str VARCHAR(6) = '000000'
-- Generate table alike to yours
DECLARE #yourTable TABLE ([value] varchar(max))
-- convert array to xml
;WITH cte AS
(
SELECT
ROW_NUMBER() OVER (ORDER BY (SELECT NULL)) AS rn,

AND TestModel = 'IR'
)
-- do the stuff
SELECT
c.rn,
c.[response],
c.[item_identifier],
RIGHT(#zero_str +
CAST(SUM(CAST(STUFF(#zero_str,t.c.value('.','tinyint')+1,1,'1') AS INT)) AS VARCHAR(6)), 6) AS ans,

FROM
cte c
CROSS APPLY
x.nodes('/a') AS t(c)
GROUP BY
c.rn, c.[response], c.UserId, c.[Item_Identifier]
ORDER BY
c.rn
COMMIT TRAN
What changes I need to do in above procedure to get 25 records as a result instead of 22, For IR21,IR22 and IR25 I want null data in response and ans columns for that respective userId? May i need to use some other function instead of CROSS APPLY? How it will be?
You were almost there. Use OUTER APPLY instead of CROSS APPLY
create table T1
(
Name varchar(50),
Address varchar(50),
Tel varchar(50)
);
create table T2
(
ParamName varchar(50),
ParamValue Varchar(60),
TableName varchar(50)
);
insert into T2 values('Name', 'test', 'Member');
insert into T2 values('Address', 'testAdd', 'Member');
insert into T2 values('Tel', 'test', 'Member');
insert into T1(Select distinct ParamName from T2)
values(select ParamValue from T2 )
I'm looking for a way to do a insertion to T1 table by getting value and column name from T2 table.need to get column name from T2 table and Value to that particular column
You can use this:
INSERT INTO T2(Column1,Column2)
SELECT Column1, Column2 FROM T1
GROUP BY Column1;
You could try using a pivot query on T2 to get the names, addresses, and telephone numbers onto a single row for each table name. Then, just do an INSERT INTO ... SELECT as you were, except use the pivoted result.
INSERT INTO T1 (Name, Address, Tel)
SELECT
MAX(CASE WHEN ParamName = 'Name' THEN ParamValue END) AS Name,
MAX(CASE WHEN ParamName = 'Address' THEN ParamValue END) AS Address,
MAX(CASE WHEN ParamName = 'Tel' THEN ParamValue END) AS Tel
FROM T2
GROUP BY TableName
-- WHERE TableName IN ('Member', ...)
You can uncomment the WHERE clause if you want to restrict the insert to certain table names.
As a general comment, if you are doing this to get your data into a more normalized form, then I think it is good. But if you plan on storing your data like this long term, you might want to reconsider your table design.
Your table structure doesn't make much sense. There is no obvious logical relation between the tables. Is the second one just a buffer table?
In any case however, if you want to insert values from a table into another table you do it like that:
INSERT INTO [target_table] ([target_column_1], [target_column_2], ..., [target_column_n])
SELECT [source_column_1], [source_column_2], ..., [source_column_n]
FROM [source_table]
WHERE [conditon]
I think you are looking like..
INSERT INTO T1(Name)
SELECT DISTINCT ParamName FROM T2
DECLARE #TableName varchar(50) = 'T1'
DECLARE #ColumnName varchar(MAX)
SELECT #ColumnName= coalesce(#ColumnName + ', ', '') + a.COLUMN_NAME
from (SELECT COLUMN_NAME
FROM INFORMATION_SCHEMA.COLUMNS
inner join T2 on TableName = TABLE_NAME
WHERE TABLE_NAME = #TableName and ParamName = COLUMN_NAME) a;
print #ColumnName
declare #ParamName varchar(MAX)
SELECT #ParamName = coalesce(#ParamName + ', ', '') + ''''+a.ParamValue+''''
from (SELECT COLUMN_NAME,ParamValue
FROM INFORMATION_SCHEMA.COLUMNS
inner join T2 on TableName = TABLE_NAME
WHERE TABLE_NAME = #TableName and ParamName = COLUMN_NAME) a;
print #ParamName
declare #QUERY nvarchar(MAX);
SET #QUERY = 'INSERT INTO T1 ('+#ColumnName+')
VALUES ('+#ParamName+')'
EXEC sp_executesql #QUERY
this is the answer what i expect ,thanks all for your help
So I am performing a while loop on 3 stored procs and inserting the data into temp tables and then performing a union on them and when I run the query It returns 10 results but when I make a report out of it in SSRS it returns just the first result and stops! shouldn't it make multiple pages with the other results?
declare #temptable table ( id int )
while (select count(*) from customerid c left join #temptable t on c.id = t.id where t.id is null) > 0 begin
insert into #temptable select min(c.id) from customerid c left join #temptable t on c.id = t.id where t.id is null
declare #id2 varchar(50) = (select max(id) from #temptable)
-- insert into temp tables here
exec DoctorsSDJs #id = #id2
-- insert into temp table
exec LocationSDJs #id = #id2
-- insert into temp tables
exec PatientSDJs #id = #id2
-- performing my union on the 3 tables
end
I have this stored procedure:
ALTER procedure [dbo].[sp_checker2]
(#Item varchar(70), #location varchar(8))
as
declare #Query varchar(2000)
set #location = 'XXX909'
declare #Table Table (Qty int)
set #Query = 'select TOP 1 * from openquery(xxxx,''SELECT NVL(b.t$st,0) from server.XXXXXID0001 a left join
server.XXXXXID0002 b on a.t$item = b.t$item where b.t$cloc = '''''+ #location + ''''' and trim(a.t$item)='''''+ #Item + ''''''')'
insert into #Table exec (#Query)
if not exists (select * from #Table )
begin
set #Query = 'select TOP 1 * from openquery(xxxx,''SELECT NVL(b.t$st,0) from server.XXXXXID0001 a
left join server.XXXXXID0002 b on a.t$item = b.t$item where trim(a.t$item) = '''''+ #Item + ''''''' )'
insert into #Table exec (#Query)
end
select * from #Table
The thing is I am looking to a query SELECT like this:
SELECT
column1, column2, column3, column4,
(EXEC [dbo].[sp_checker2] 'param1=value of column3', 'param2=another value') AS column5
FROM
table
WHERE
column1 = 'data1'
AND column2 = 'data2'
ORDER BY
column3
I know it is not possible to execute a stored procedure in a SELECT statement in SQL Server and the alternative I have is to convert the stored procedure to a function, but inside the stored procedure I have an exec to insert data into the table variable. Is there a way I can convert this stored procedure to a function ?
P.S. I only save one row in the variable table, ie: if item exists it saves its inventory: "6500"
It is difficult. In a function it is not possible to execute dynamic SQL. I think it is only possible if the WHERE criteria are shifted. You'll be better able to evaluate what impact this has on the performance.
CREATE FUNCTION [dbo].[f_checker2] (#item varchar(70),
#location varchar(8))
RETURNS #result TABLE (
Qty int
)
AS
BEGIN
INSERT
INTO #result
select TOP(1) qty
from openquery(xxxx, 'SELECT NVL(b.t$st,0) AS qty,
b.t$cloc AS location,
trim(a.t$item) AS item
from server.XXXXXID0001 a
left join server.XXXXXID0002 b
on a.t$item = b.t$item')
where location = #location
and item = #item
if not exists (select * from #result)
INSERT
INTO #result
select TOP(1) qty
from openquery(xxxx, 'SELECT NVL(b.t$st,0) AS qty,
b.t$cloc AS location,
trim(a.t$item) AS item
from server.XXXXXID0001 a
left join server.XXXXXID0002 b
on a.t$item = b.t$item')
where item = #item
RETURN
END

I have a table where I am storing all tables name and column name, now I want to get data according to that table with different conditions.
I will use one single query column name and table name will take dynamically from this table and than I will use in select query and will get data from respective column and table.
Table name is ADE_ColumnIndexing
In this table I have all table names as TableName column, and column names as name column...
Now I want to use
select fieldname
from tablename
where Id = newdata
This query will return data of that column and table... I mean tablename = ade_log and columnname = history...
So my query will be select history from ade_log... Is it possible?
It's possible to build and execute dynamic sql, though it doesn't seem like a good aproach:
DECLARE #Sql varchar(max)
SELECT #Sql = 'SELECT '+ ColumnName +
' FROM '+ TableName +
' WHERE Id = '+ IdValue
FROM ADE_ColumnIndexing
WHERE TableName = #TableName
AND ColumnName = #ColumnName
EXEC(#Sql)
I think if you use the ID column for search, definitely not recommended as it may seem to me, the IDVal is auto-increment (correct me if i'm wrong). So why not use
exec('select [' + #column_name + '] from [' + #tablename + ']');
if you want an added validation if the table or column exists, you may query in sys.
if (
select
COUNT(*)
from sys.tables tb
left join sys.columns c
on
tb.object_id = c.object_id
where
tb.name = #tablename
and c.name = #columnname
) != 0
begin
exec('select [' + #column_name + '] from [' + #tablename + ']');
end
else
begin
select 'table or column does not exist'
end
EDIT : Seems like your table has "queries" as a row, then see my simple script below if I understand you correctly....(hopefully)
CREATE TABLE test (qry nvarchar(4000)) -- test query table
CREATE TABLE test1 (sales decimal(18,2)) -- sales table
INSERT INTO test1 (sales) -- dummy records for sales table
