SQL Server 2008 : Multiple Queries in One Stored Procedure

Question

I have 2 stored procedures that retrieve data from a table called Places. The procedures are called by C# code one at a time. These are the table columns.

Answer 1

Give this a try:

CREATE procedure GetNearbyPlaces
  @Id int
AS
BEGIN
  Declare @Min_Lat decimal(18, 3)
  Declare @Min_Lng decimal(18, 3)
  Declare @Max_Lat decimal(18, 3)
  Declare @Max_Lng decimal(18, 3)

  SELECT @Min_Lat=Latitude - 0.005,
    @Min_Lng=Longitude - 0.005,
    @Max_Lat=Latitude + 0.005,
    @Max_Lng=Longitude + 0.005
  FROM Places
  WHERE Id = @Id

  SELECT *
  FROM Places 
  WHERE Latitude BETWEEN @Min_Lat AND @Max_Lat
  AND   Longitude BETWEEN @Min_Lng AND @Max_Lng
  ORDER By ID ASC

END
GO

After relooking this over, another issue you could potentially be having is with DECIMAL(18,2) -- I think this needs to be DECIMAL(18,3) since you're offsetting with .005.

Here is a simpler version with a single sql statement:

SELECT P.*
  FROM Places P
    JOIN (
      SELECT Latitude - 0.005 Min_Lat,
        Longitude - 0.005 Min_Lng,
        Latitude + 0.005 Max_Lat,
        Longitude + 0.005 Max_Lng
      FROM Places
      WHERE Id = @Id
      ) P2 ON P.Latitude BETWEEN P2.Min_Lat AND P2.Max_Lat
          AND P.Longitude BETWEEN P2.Min_Lng AND P2.Max_Lng
  ORDER By ID ASC
