duan xiong updated CALCITE-4871:
--------------------------------
Description:
In calcite. The precision and scale can't work.
1) Add judgment in decimal type precision and scale parameter(When have illegal
value need to throw an exception):
SQL EXAMPLES:
{code:java}
cast(155.36 as decimal(0,0)){code}
In Postgresql:
{noformat}
ERROR: NUMERIC precision 0 must be between 1 and 1000{noformat}
In Calcite:
{noformat}
EXPR$0=155.36{noformat}
2) To make sure return the right answer。
SQL EXAMPLES:
{code:java}
cast(155.36 as decimal(4,1)){code}
In Postgresql:
{code:java}
EXPR$0=155.4{code}
In Calcite:
{code:java}
EXPR$0=155.36{code}
The problem exists in cast different di
was:In calcite. The precision and scale can't work.
> CAST a literal to DECIMAL type return wrong result
