It appears to be the blank space in DEF_WELD_ INC, which should be DEF_WELD_INC. I created a table v_biq_r8_qwb_events to match the columns expected by subquery "AQE Source Data 5.30.2018", removed the line breaks in things like
ON ("AQE Source Data 5.30.2018"."EVENT_NO" = "400
Machines"."MIN(EVENT_NO)")
which I’m assuming should be
ON ("AQE Source Data 5.30.2018"."EVENT_NO" = "400 Machines"."MIN(EVENT_NO)")
and that was the only error.
solved SQL ORA-02063 – How to fix this?
