Example MSSQL and MySQL tables to hold logging data:

/*MSSQL*/
CREATE TABLE [dbo].[CRUSHFTP_LOG](
 [LOG_ROW_NUM] [float] NOT NULL,
 [LOG_MILLIS] [float] NOT NULL,
 [LOG_TAG] [varchar](50) NULL,
 [LOG_DATA] [varchar](2000) NULL,
CONSTRAINT [PK_CRUSHFTP_LOG] PRIMARY KEY CLUSTERED
(
 [LOG_ROW_NUM] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]



/*MYSQL*/
CREATE TABLE `CRUSHFTP_LOG` (
	  LOG_ROW_NUM DOUBLE NOT NULL PRIMARY KEY,
	  LOG_MILLIS DOUBLE NOT NULL,
	  LOG_TAG VARCHAR(50) DEFAULT NULL,
	  LOG_DATA VARCHAR(2000) DEFAULT NULL);

And a more optimized and tweaked version for MS SQL:
