SQL Server 2008 R2: Cursor with condition - sql-server

Question

I have the table which contains the table's id and name.
Now I want to retrieve the table names by passing table ID to the stored procedure.
Example:
create procedure spGetAllTables
#TableIDs varchar(max)
AS
DECLARE #Tables varchar(max)
DECLARE Cur1 CURSOR FAST_FORWARD FOR
SELECT TableName FROM TablesContainer
WHERE TableID IN (#TableIDs)
OPEN Cur1
FETCH NEXT FROM Cur1 INTO #Tables
WHILE(##FETCH_STATUS=0)
BEGIN
PRINT(#Tables)
FETCH NEXT FROM Cur1 INTO #Tables
END
CLOSE Cur1;
DEALLOCATE Cur1;
GO
Explanation: The table TablesContainer contains all table's ID's and table's names. I just want to print all those table names which I have passed their table ID's to the stored procedure.
The procedure working fine if I pass single value to the variable #TableIDs. But If I pass multiple values like 1,2,3 to #TableIDs then its not getting entered into the cursor.

Answer 1

i think you don't need cursor, there is multiple way to separate string you can pass table value parameter and split the string but as per the Q requirement Reference
DECLARE #temp TABLE (Id INT)
INSERT INTO #temp VALUES (1),(2),(6)
DECLARE #TableIDs varchar(max),
#xml xml
SELECT #TableIDs = '1,2,3,4,5'
SELECT #xml = CONVERT(xml,' <root> <x>' + REPLACE(#TableIDs,',','</x> <x>') + '</x> </root> ')
SELECT id FROM #temp
WHERE id IN (
SELECT T.c.value('.','INT')
FROM #xml.nodes('/root/x') T(c)
)

You don't neet to pass the IDs as a CSV list. SQL Server has table-valued parameters since the SQL Server 2008 version at least. A TVP is a table parameter to which you insert data with plain INSERT statements in SQL, or as an collection (a DataTable or DataReader) in ADO.NET.
You can JOIN with the TVP as you would with any table or table variable.
First, you need to define the TVP type in the database:
CREATE TYPE IdTableType AS TABLE ( ID uniqueidentifier);
Then you can write a stored procedure to use it:
create procedure spGetAllTables(#TableIDs IdTableType READONLY)
AS
SELECT TableName
FROM TablesContainer
inner join #TableIDs on #TableIDs.ID=TablesContainer.TableID
To call the stored procedure from T-SQL you can create a table parameter and fill it:
declare #tableIds IdTableType;
insert into #tableIds
VALUES
('....'),
('....');
exec #spGetAllTables(#tableIds);
