Question

After having created a temporary table and declaring the data types like so;

CREATE TABLE #TempTable(
ID int,
Date datetime,
Name char(20))

H

Answer 1

I have provided two approaches to solve the same issue,

Solution 1: This approach includes 2 steps, first create a temporary table with specified data type, next insert the value from the existing data table.

CREATE TABLE #TempStudent(tempID  int, tempName  varchar(MAX) )
INSERT INTO #TempStudent(tempID, tempName) SELECT id, studName FROM students where id =1

SELECT * FROM #TempStudent

Solution 2: This approach is simple, where you can directly insert the values to temporary table, where automatically the system take care of creating the temp table with the same data type of original table.

SELECT id, studName  INTO #TempStudent FROM students where id =1

SELECT * FROM #TempStudent
