Description
1. crate a table by the schema as below:
CREATE TABLE IF NOT EXISTS Miss_data_table(
a BIGINT NOT NULL,
b VARCHAR,
c INTEGER,
d INTEGER,
e INTEGER,
f INTEGER,
g VARCHAR,
h VARCHAR,
i INTEGER,
j VARCHAR,
k INTEGER,
l VARCHAR,
m VARCHAR,
n INTEGER,
o INTEGER,
p VARCHAR,
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')
4. execute querys...
select a,b,c,d,e,f,g,h,i,j,k,l,m,n,o,p,q,r,s,t from Miss_data_table where q = '102218';
----------------------------------------------------------------------------------------------------+
| A | B | C | D | E | F | G | H | I | J | K | L | M | N | O | P | Q | R | S | T |
----------------------------------------------------------------------------------------------------+
| 96660688 | hello/TEST-0 | NULL | NULL | NULL | NULL | NULL | NULL | NULL | NULL | NULL | NULL | NULL | NULL | NULL | NULL | 102218 | NULL | 26 | 20141201 |
----------------------------------------------------------------------------------------------------+
select a,b,c,d,e,f,g,h,i,j,k,l,m,n,o,p,q,r,s,t from Miss_data_table where a=96660688;
-------------------------------------------------------------------------------------------------------------------------------+

-------------------------------------------------------------------------------------------------------------------------------+
// execute the query plain ,it shows we fetch data by local index.
explain select a,b,c,d,e,f,g,h,i,j,k,l,m,n,o,p,q,r,s,t from Miss_data_table where q = '102218';
