SELECT * FROM sys.storage WHERE 1=1 AND "schema" = 'sapsr3' AND "table" = 'dfkkop' ; works in mclient and DBVisualizer (via JDBC) SELECT * FROM sys.storage WHERE 1=1 AND "schema" = 'sapsr3' --AND "table" = 'dfkkop' ; works in mclient, but does not work in DBVisualizer. error message: 11:23:37 [SELECT - 0 row(s), 0.000 secs] 1) [Error Code: 0, SQL State: 42000] syntax error, unexpected $end, expecting SCOLON in: "select. 2) [Error Code: 0, SQL State: 22000] *. 3) [Error Code: 0, SQL State: 22000] from. 4) [Error Code: 0, SQL State: 22000] sys.storage. 5) [Error Code: 0, SQL State: 22000] where 1=1. 6) [Error Code: 0, SQL State: 22000] and "schema" = 'sapsr3'. 7) [Error Code: 0, SQL State: 22000] --AND "table" = 'dfkkop';" ... 1 statement(s) executed, 0 row(s) affected, exec/fetch time: 0.000/0.000 sec [0 successful, 0 warnings, 1 errors] I also noticed this problem (handling comments) in other statements, especially when comments appear before the semicolon. I am not sure, if this is a problem in JDBC driver or DBVisualizer. To see, what is received by monetdb server, I would like to see log files of SQL queries. I found a directory named "/sql_logs/sql", but it consits of 2 files nearly empty. Where can I enable logging?
