             Summary: Support data insertion in a different order if you wish or even omit some columns in spark sql also like postgresql
                 Key: SPARK-29591
                 URL: https://issues.apache.org/jira/browse/SPARK-29591
             Project: Spark
          Issue Type: Sub-task
          Components: SQL
    Affects Versions: 2.4.4
            Reporter: jobit mathew


Support data insertion in a different order if you wish or even omit some columns in spark sql also like postgre sql.

*In postgre sql*

CREATE TABLE weather (
 city varchar(80),
 temp_lo int, -- low temperature
 temp_hi int, -- high temperature
 prcp real, -- precipitation
 date date
);

*You can list the columns in a different order if you wish or even omit some columns,*

INSERT INTO weather (date, city, temp_hi, temp_lo)
 VALUES ('1994-11-29', 'Hayward', 54, 37);

*But in spark sql i*s not allowing to insert data in different order or omit any column.Better to support this as it can save time if we can not predict any specific column value or if some value is fixed always.

create table jobit(id int,name string);

> insert into jobit values(1,"Ankit");
Time taken: 0.548 seconds
spark-sql> *insert into jobit (id) values(1);*
*Error in query:*
mismatched input 'id' expecting \{'(', 'SELECT', 'FROM', 'VALUES', 'TABLE', 'INSERT', 'MAP', 'REDUCE'}(line 1, pos 19)

== SQL ==
insert into jobit (id) values(1)
-------------------^^^

spark-sql> insert into jobit (name,id) values("Ankit",1);
Error in query:
mismatched input 'name' expecting \{'(', 'SELECT', 'FROM', 'VALUES', 'TABLE', 'INSERT', 'MAP', 'REDUCE'}(line 1, pos 19)

== SQL ==
insert into jobit (name,id) values("Ankit",1)
-------------------^^^
