How to insert multiple select statements into a temp table

Question

I am having three tables with different data and i need to insert into one TEMP table and return that table in StoredProcedure.

I tried as:

-- To get last 10 Days Letters count
SELECT col1,col2,1 AS Type, LettersCount
INTO #temp FROM tblData

-- To get last 4 weeks Letters count
SELECT col1,col2,2 AS Type, LettersCount
INTO #temp FROM tblData

-- To get month wise Letters count
SELECT col1,col2,3 AS Type, LettersCount
INTO #temp FROM tblData

Showing Error as

Msg 2714, Level 16, State 1, Line 16
There is already an object named '#temp ' in the database.
Msg 102, Level 15, State 1, Line 24
Incorrect syntax near 'T'.
Msg 2714, Level 16, State 1, Line 32
There is already an object named '#temp ' in the database.

Answer 1

Create the temporary table once, then insert into it for the other two SELECT statements:

SELECT col1, col2, 1 AS Type, LettersCount
  INTO #temp
  FROM tblData;

INSERT INTO #temp
    SELECT col1, col2, 2 AS Type, LettersCount
      FROM tblData;

INSERT INTO #temp
    SELECT col1, col2, 3 AS Type, LettersCount
      FROM tblData;
