> 1. crate a table by the schema as below:
> CREATE TABLE IF NOT EXISTS Miss_data_table(

> q VARCHAR,
> r INTEGER,
> s BIGINT,
> t VARCHAR CONSTRAINT pk PRIMARY KEY(a))
> 2.create local index for the table with column: q
> create local index idx_q on Miss_data_table (q);
> 3.upsert data into table.
> upsert into Miss_data_table values(96660688,'hello/TEST-0',156,-1,-1,0,'2013-02-14 18:34:05.0','TEST-1',0,'495839182',0,'50','',0,0,'1818378','102218',0,26,'20141201')
