This function search a word in all the sysobjects and return the result with the source (storedprocedure, table, ...).

Thanks to my colleague Nicolas Pecqueux for this script, I've juste adapted it.

CREATE Function [dbo].[udf_Find] (@string varchar(100))
RETURNS @retTable TABLE 
(
    NameObject nvarchar(128) NULL,
    ObjectType nvarchar(100) NULL,
    NameParent nvarchar(128) NULL,

RETURN
END

Example and result :

SELECT * FROM dbo.udf_Find('Theme')

This function return a varchar with the date and time from a datetime parameter.

The string returned is in french but can be adapted in other language.

CREATE FUNCTION [dbo].[ConvertDateToVarchar]
(	
	@Date DateTime
)
RETURNS TABLE 
AS
RETURN 
(
	SELECT	DateStr =	CASE	WHEN @Date Is Null THEN 'Jamais' 
								WHEN (DatePart(hour, @Date) = 0 AND DatePart(Minute, @date) = 0) THEN CONVERT(VARCHAR, @Date, 105)
						ELSE	CONVERT(VARCHAR, @Date, 105) + ' à ' + 
								REPLACE(CONVERT(VARCHAR(5), @Date, 108),':', 'h')
						END
