conn.Open()

& "reqStat,location,approvalNo,evalRem,itscRem,evaltoitscRem,dateSubmit) " _

& "VALUES(:reqNo,:userID,:reqType,:projTitle,:dept,:d_section,:unit,:author,:targetDate, " _

& ":reqStat,:location,:approvalNo,:evalRem,:itscRem,:evaltoitscRem,:dateSubmit)"

reqCmd.Parameters.Add("reqNo", OracleType.Number, 5, 1)

reqCmd.Parameters.Add("userID", OracleType.VarChar, 50, "chico")

reqCmd.Parameters.Add("reqType", OracleType.Number, 1, 1)
