Merge clause retrieves ORA-00923 FROM keyword not found where expected
Hi everyone,
Using the MERGE clause i want to be able to update/insert records each
15 minutes, so i probe each segment of this code and its working, in
fact the segment with the MERGE works perfect replacing the
vPMM_DATETIME and vEND_DATETIME variables for constants, but (and its
driving me crazy!!!) when i probe this huge query, i get the error:
Error: ORA-00923: FROM keyword not found where expected
ORA-06512: at line 63, Batch 1 Line 1 Col 1
Line 63 is the MERGE INTO OM_DB.CDRS_VALIDOS "X", so whats
happening??? because each segment of the code works if i probe one by
one!!, please some help!!!
Code:
DECLARE
vPMM_DATETIME TIMESTAMP(3);
vMAX_PMM_DATETIME TIMESTAMP(3);
vEND_DATETIME TIMESTAMP(3);
v_rows_processed INT;
count_violated INT;
BEGIN
dbms_output.enable(40000);
