… nested decimal precision (apache#48964) before this pr , we deduce the precision of the function named_struct containing the decimal type is same with the precision of the decimal type in select . In this case we can not make right named_struct for multiple decimal value like : ``` mysql> create table t01 (a decimal(6,3), d struct<col:bigint, col1:decimal(7,2)>) properties ("replication_num"="1"); Query OK, 0 rows affected (0.14 sec) mysql> insert into t01 values (123.321, named_struct('col', 1, 'col1', 345.24)); Query OK, 1 row affected (0.26 sec) {'label':'label_a2dc895ee7834701_841639ad6d93923f', 'status':'VISIBLE', 'txnId':'9010'} mysql> select named_struct("col_11", a, "col_12", d) from t01; +--------------------------------------------------------+ | named_struct("col_11", a, "col_12", d) | +--------------------------------------------------------+ | {"col_11":123.321, "col_12":{"col":1, "col1":345.240}} | +--------------------------------------------------------+ 1 row in set (0.17 sec) mysql> insert into t01 values (123.321, named_struct('col', 1, 'col1', 12345.24)); Query OK, 1 row affected (0.17 sec) {'label':'label_77ed6047f6a6494d_810c26becfd0535c', 'status':'VISIBLE', 'txnId':'9011'} mysql> select named_struct("col_11", a, "col_12", d) from t01; ERROR 1105 (HY000): errCode = 2, detailMessage = (10.16.10.6)[E-255]Arithmetic overflow when converting value 12345.24 from type Decimal(7, 2) to type Decimal(6, 3) mysql> desc verbose select named_struct("col_11", a, "col_12", d) from t01; +----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ | Explain String(Nereids Planner) | +----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ | PLAN FRAGMENT 0 | | OUTPUT EXPRS: | | named_struct("col_11", a, "col_12", d)[apache#2] | | PARTITION: RANDOM | | | | HAS_COLO_PLAN_NODE: false | | | | VRESULT SINK | | MYSQL_PROTOCAL | | | | 0:VOlapScanNode(50) | | TABLE: tt.t01(t01), PREAGGREGATION: ON | | partitions=1/1 (t01) | | tablets=10/10, tabletList=1741751856342,1741751856344,1741751856346 ... | | cardinality=2, avgRowSize=2955.0, numNodes=1 | | pushAggOp=NONE | | final projections: named_struct('col_11', a[#0], 'col_12', CAST(d[#1] AS struct<col:bigint,col1:decimalv3(6,3)>)) | | final project output tuple id: 1 | | tuple ids: 0 | | | | Tuples: | | TupleDescriptor{id=0, tbl=t01} | | SlotDescriptor{id=0, col=a, colUniqueId=0, type=decimalv3(6,3), nullable=true, isAutoIncrement=false, subColPath=null} | | SlotDescriptor{id=1, col=d, colUniqueId=1, type=struct<col:bigint,col1:decimalv3(7,2)>, nullable=true, isAutoIncrement=false, subColPath=null} | | | | TupleDescriptor{id=1, tbl=t01} | | SlotDescriptor{id=2, col=null, colUniqueId=null, type=struct<col_11:decimalv3(6,3),col_12:struct<col:bigint,col1:decimalv3(6,3)>>, nullable=false, isAutoIncrement=false, subColPath=null} | | | | | | ```
