Shwetha G S updated ATLAS-166:
------------------------------
Description:
"Table as t, sd, Column as c where t.name=\"sales_fact\" select c.name as
colName, c.dataType as colType"
is translated to
{noformat}
L:{_var_0 = [] as Set;g.V().has("__typeName",
"Table").fill(_var_0);g.V().has("__superTypeNames",
"Table").fill(_var_0);_var_0._().as("t").out("__Table.sd").in("__Column.sd").as("c").and(_().back("t").has("Table.name",
T.eq,
"sales_fact")).as("_src1").select(["c"]){[it."Column.name",it."Column.dataType"]}.toList()}
{noformat}
Even after fix for ATLAS-145 which fixes the back reference , select (["c"])
doesnt work and throws an error
{noformat}
L:{_var_0 = [] as Set;g.V().has("__typeName",
"Table").fill(_var_0);g.V().has("__superTypeNames",

and(_().has("Table.name", T.eq,
