Hi,
I am using the Jdbc Adapter to generate a sql query using a Oracle
DataSource.
The question is about this particular calcite query:
SELECT v1272.`QUESTN_LBL` `Label (Question Metrics)`,v1274.`LBL` `Label
> (Question)`,v1272.`CLICKTHRU_CNT` `Click Thru Count (Question
> Metrics)`,v1272.`CLICKTHRU_RATIO` `Click Thru Ratio (Question
> Metrics)`,v1272.`DATE` `Date (Question Metrics)`,v1272.`HAS_RESPONSES` `Has
> Responses (Question Metrics)`,v1272.`LOCALE_KEY` `Locale (Question
> Metrics)`,v1272.`QUESTN_CNT` `Question Count (Question
> Metrics)`,v1272.`QUESTN_KEY` `NAVIGATION_8_QUESTION` FROM
> DW_REPORTING.QUESTION v1272 LEFT JOIN DW_REPORTING.METRICS v1274 ON
> v1272.`QUESTN_KEY` = v1274.`QUESTN_KEY` WHERE UPPER(CAST(v1274.`LBL` AS
> VARCHAR(1000))) LIKE UPPER('% den %')
That generates the following query:
SELECT "QUESTN_LBL" "Label (Question Metrics)", "LBL" "Label (Question)",
> "CLICKTHRU_CNT" "Click Thru Count (Question Met", "CLICKTHRU_RATIO" "Click
> Thru Ratio (Question Met", "DATE" "Date (Question Metrics)",
> "HAS_RESPONSES" "Has Responses (Question Metric", "LOCALE_KEY" "Locale
> (Question Metrics)", "QUESTN_CNT" "Question Count (Question Metri",
> "QUESTN_KEY" "NAVIGATION_8_QUESTION", "ID", "QUESTN_KEY0" "QUESTN_KEY"
> FROM (SELECT "ID", "QUESTN_KEY", "LOCALE_KEY", "QUESTN_LBL", "DATE",
> "QUESTN_CNT", "CLICKTHRU_CNT", "CLICKTHRU_RATIO", "HAS_RESPONSES"
> FROM "DW_REPORTING"."QUESTION") "t"
> LEFT JOIN (SELECT "QUESTN_KEY", "LBL"
> FROM "DW_REPORTING"."METRICS") "t0" ON "t"."QUESTN_KEY" = "t0"."QUESTN_KEY"
> WHERE UPPER("t0"."LBL") LIKE UPPER('% den %')
The problem here is with the "QUESTN_KEY0" doesn't exist, Both "t" and "t0"
have the "QUESTN_KEY" field and after the JdbcFilter, the table alias "t"
and "t0" seems to disappear.
This is the generated plan:
[TABLE, #ID {PLAN=JdbcToEnumerableConverter
> JdbcProject(Label (Question Metrics)=[$3], Label (Question)=[$10],
> Click Thru Count (Question Metrics)=[$6], Click Thru Ratio (Question
> Metrics)=[$7], Date (Question Metrics)=[$4], Has Responses (Question
> Metrics)=[$8], Locale (Question Metrics)=[$2], Question Count (Question
> Metrics)=[$5], NAVIGATION_8_QUESTION=[$1], ID=[$0], QUESTN_KEY=[$9])
> JdbcFilter(condition=[LIKE(UPPER(CAST($10):VARCHAR(1000) CHARACTER
> SET "ISO-8859-1" COLLATE "ISO-8859-1$en_US$primary"), UPPER('% den %'))])
> JdbcJoin(condition=[=($1, $9)], joinType=[left])
> JdbcProject(ID=[$0], QUESTN_KEY=[$1], LOCALE_KEY=[$2],
> QUESTN_LBL=[$3], DATE=[$4], QUESTN_CNT=[$5], CLICKTHRU_CNT=[$6],
> CLICKTHRU_RATIO=[$8], HAS_RESPONSES=[$9])
> JdbcTableScan(table=[[DW_REPORTING, QUESTION]])
> JdbcProject(QUESTN_KEY=[$0], LBL=[$1])
> JdbcTableScan(table=[[DW_REPORTING, METRICS]])
> , }]
Can you tell me what is wrong with this particular query?
Best regards,
Miguel.
