I need to Create a stored procedure to insert 1 million entries into my table tbl_student and execute it.

Columns:

int_enrollment_no(int),
pk_int_roll_no(int primarykey),
vchr_name(varchar),
vchr_city(varchar),
vchr_mobileno(varchar),
dat_dob(date)

Open in new window


These are the attributes, but the entries shouldn't be equal. I must insert random values. I need code for this.

Use this as an example:
CREATE TABLE #TEST
(
	int_enrollment_no int,
	pk_int_roll_no int,
	vchr_name varchar(255),
	vchr_city varchar(255),
	vchr_mobileno varchar(10),
	dat_dob date
)

CREATE PROCEDURE INSERT_PROC
AS
BEGIN
	DECLARE @lnMIN INT,
			@lnMAX INT
	SELECT @lnMIN = 0		
			
	WHILE (@lnMIN < 100)
	BEGIN
		INSERT INTO #TEST
		SELECT
			CEILING(RAND() * 1000000),
			CEILING(RAND() * 10000000),
			CONVERT(varchar(255), NEWID()),
			CONVERT(varchar(255), NEWID()),
			CONVERT(VARCHAR(10),CEILING(RAND() * 1000000)),
			dateadd(second,(rand()*60+1),DATEADD(minute,(rand()*60+1) ,DATEADD(day,(rand()*365+1),DATEADD(year,-1,getdate()))) )
		SELECT @lnMIN = @lnMIN + 1
	END
END
GO
