Cheng Lian updated SPARK-13772:
-------------------------------
Description:
Code snippet to reproduce this issue using 1.6.0:
{code}
select if(1=1, cast(1 as double), cast(1.1 as decimal) as a from test
{code}
It will throw exceptions like this：
{noformat}
Error in query: cannot resolve 'if ((1 = 1)) cast(1 as double) else cast(1.1 as
decimal(10,0))' due to data type mismatch: differing types in 'if ((1 = 1))
cast(1 as double) else cast(1.1 as decimal(10,0))' (double and decimal(10,0)).;
line 1 pos 37
{noformat}
I also tested:
{code}
select if(1=1,cast(1 as decimal),cast(1 as decimal(19,6))) from test;
{code}
{noformat}
Error in query: cannot resolve 'if ((1 = 1)) cast(1 as decimal(10,0)) else
cast(1 as decimal(19,6))' due to data type mismatch: differing types in 'if ((1
= 1)) cast(1 as decimal(10,0)) else cast(1 as decimal(19,6))' (decimal(10,0)
and decimal(19,6)).; line 1 pos 38
{noformat}

I found a bug：
select if(1=1, cast(1 as double), cast(1.1 as decimal) as a from test
It will throw exceptions like this：

decimal(10,0))' due to data type mismatch: differing types in 'if ((1 = 1))
cast(1 as double) else cast(1.1 as decimal(10,0))' (double and decimal(10,0)).;

I also test：
select if(1=1,cast(1 as decimal),cast(1 as decimal(19,6))) from test;
Error in query: cannot resolve 'if ((1 = 1)) cast(1 as decimal(10,0)) else

and decimal(19,6)).; line 1 pos 38
