cmd.CommandText = "CREATE TABLE custmast (" +
"cm_custnumb CHAR(4)," +
"cm_custzipc CHAR(9)," +
"cm_custstat CHAR(2)," +
"cm_custrtng CHAR(1)," +
"cm_custname VARCHAR(47)," +
"cm_custaddr VARCHAR(47)," +
"cm_custcity VARCHAR(47))";
cmd.ExecuteNonQuery();
}
catch (CtreeSqlException e)
{
Handle_Exception(e);
}
