Numbers

This collection of SQL artefacts can be used to randomly generate integer values, either singularly or in batches of up to 10000 values.

Reference data.

Bulk procedures described below generate values based on the values in [Reference].[Number]. This table can be populated by executing the procedure [Reference].[usp_Populate_Number].

Procedures and functions

[SingleValue].[ufn_Get_number]

This function will return a random integer value. As a function; this method can be used to easily assign a value to an variable, or to update a field on a table.

This function has the following input parameters:

Parameter	Data Type	Default Value
@MinValue	int	None
@MaxValue	int	None

Example usages:

Declare	@Number int 
Select	@Number = [SingleValue].[ufn_Get_number]( 1, 100 )
Select	@Number

[SingleValue].[usp_Get_number]

This procedure will return a random integer value. The generated value is returned via the output parameter @Number, and so can be captured in a variable or passed back to a calling application.

Parameter	Data Type	Default Value	Direction
@MinValue	int	1	Input
@MaxValue	int	9	Input
@Number	int	None	Output

Example usages:

Declare @Number int
exec	SingleValue.usp_Get_Number @MinValue = 95, @MaxValue = 100, @Number = @Number out
Select	@Number

[BulkValue].[usp_Get_number]

This procedure will return up to 10000 random integer values. This procedure has the following input parameter:

Parameter	Data Type	Default Value
@MinValue	int	1
@MaxValue	int	9
@QuantityRequired	smallint	None

A recordset with the following structure is returned:

Field Name	Data Type
Number	int

This method is useful for inserting bulk data directly in to a table, or as an ETL source.

Example Usage:

exec [BulkValue].[usp_Get_Number] 95, 100, 1000
