Hi, I have problems with the parameter transfer to a zsql-method: With the Test - Tab of the ZMI the following ZSQL-method works fine without passing any parameters (i.e. with the default values) But if I call it with "return db.sql.device_list()", with "db.sql.device_list(['col1','col2'])" or with "db.sql.device_list(columns=['col1','col2'])" from a script I get the given errors. Can anybody enlight my understandig of how to pass parameters (e.g. lists, dictionaries) to zsql-methods especially so that they will work in an dtml-in construct? That would be very helpfull. --Thanks, Elena my ZSQL-Method: <params>columns:list:string=* where:string="" sort_col:string="" sort_reverse:int=0</params> SELECT <dtml-in columns prefix=column> <dtml-var column_item fmt=sql-quote><dtml-unless column_end>, </dtml-unless> </dtml-in> FROM device_list the error details: Error Type: InError Error Value: Strings are not allowed as input to the in tag.
