I have noticed that Drill keeps the view definition in the same directory as the data. Should this not be ignored by default instead of having to specify what files to query?
-----Original Message----- From: England, Michael (IT/UK) Sent: 22 September 2015 09:53 To: [email protected] Subject: Drill view schema returned in results set Hi, I was trying to run a SUM() function on a view but was getting the following error: ERROR [HY000] [MapR][Drill] (1040) Drill failed to execute the query: select sum(x) from `mike`.`view`.`test_view ` [30027]Query execution error. Details:[ SYSTEM ERROR: CompileException: Line 33, Column 177: Unknown variable or type "logger" Fragment 0:0 [Error Id: 68c7c5b8-8875-4834-8977-c514a08ca8b0 on x.mydomain.com:31010] ] I ran a distinct on the column to check all of the data types in the column were an integer but saw that one row contained no data. I orginally thought that it was my data causing the issue, but on further analysis I saw the view schema being returned in the first column which seems to be causing the issue: select * from `mike`.`view`.`myview` where isnumeric(x) = 0 { "name" : "test_view ", "sql" : "SELECT `columns`[0] AS `x`, `columns`[1] AS `x1`, `columns`[2] AS `x2`, `columns`[3] AS `x3`, `columns`[4] AS `x4`, `columns`[5] AS `x5`, `columns`[6] AS `severity`, `columns`[7] AS `x6`\nFROM `mike`.`view`.`.`", "fields" : [ { "name" : "x", "type" : "ANY", "isNullable" : true }, { "name" : "x1", "type" : "ANY", "isNullable" : true }, { "name" : "x2", "type" : "ANY", "isNullable" : true }, { "name" : "x3", "type" : "ANY", "isNullable" : true }, { "name" : "x4", "type" : "ANY", "isNullable" : true }, { "name" : "x5", "type" : "ANY", "isNullable" : true }, { "name" : "x6", "type" : "ANY", "isNullable" : true }, { "name" : "x7", "type" : "ANY", "isNullable" : true } ], "workspaceSchemaPath" : [ ] } Is this expected behaviour or does it look like a bug. Has anyone come across this before?
