In other words, if I have loaded some tables in the Denodo, the transactional systems continue to fill my database (tables), as Denodo can be configured so that they reload the tables with the new data automatically and replicate at Views created Sat, 18 Jan 2020 04:20:12 GMT 2020-01-18T04:20:12Z PHP ODBC Binding issue with numbers/integers Closely related to this question: Binding any type of date, datetime, varchar or char seems to work. however when doing integer or decimal numbers, I receive the below error in PHP PDO. We are running PHP7.3, Denodo version 7 with a PostgreSQL backend. We've also tracked the server with logging enabled however the statement didn't even seem to hit the server. ``` DebugPDOStatement Object ( [queryString] => SELECT * from rds_homt_public_shipped_orders where ordernumber = :ordernumber ) SQL: [77] SELECT * from rds_homt_public_shipped_orders where ordernumber = :ordernumber Params: 1 Key: Name: [12] :ordernumber paramno=0 name=[12] ":ordernumber" is_param=1 param_type=1 Array ( [0] => [1] => 7 [2] => ERROR: Error executing query. Total time 0.285 seconds. QUERY [VIRTUAL] [ERROR] QUERY [JDBC WRAPPER] [ERROR] QUERY [JDBC ROUTE] [ERROR] Received exception with message 'ERROR: operator does not exist: in java.sql.SQLException: Error executing query. Total time 0.285 seconds. QUERY [VIRTUAL] [ERROR] QUERY [JDBC WRAPPER] [ERROR] QUERY [JDBC ROUTE] [ERROR] Received exception with message 'ERROR: operator does not exist: in; Error while executing the query (SQLExecute[7] at ext\pdo_odbc\odbc_stmt.c:258) [3] => ) ``` If I 'translate' the ordernumber column which is of type integer to text using CAST, it works: ``` SELECT * from rds_homt_public_shipped_orders where CAST(ordernumber AS TEXT) = :ordernumber ``` Seems that for some reason it is trying to translate the integer value to string. What I also find strange is that the ERROR message is cut off after X many characters. Is there anything you can do to help us?

Fri, 17 Jan 2020 02:36:24 GMT 2020-01-17T02:36:24Z Why do JDBC escape sequences give an error with the Denodo JDBC driver? We are using SAP Business Objects Xi 4.2 to consume data from Denodo 7.0 using the Denodo JDBC driver. However queries generated by Business Objects that use a filter on a date object return an error. The SQL is generated with the following syntax in the where clause (see example below): WHERE view_a.column_b IN ( {d '2020-01-06'} ) We see from the KB article: that denodo reccomend changing the date format property in the vdp.prm file. So we have set the property as follows; <Parameter Name="USER_INPUT_DATE_FORMAT">'dd-MMM-yyyy HH:mm:ss'</Parameter> 'dd-MMM-yyyy HH:mm:ss' is the same as the datepattern in the gb i18n map (which is the default i18n in the denodo server). Applying this change to the vdp.prm file stops the {d } escape sequence appearing in the SQL and looks like it does solve our problem. ....So our question is: Why do escape sequences like {d '2020-01-06'} cause an error in denodo? The {d '2020-01-06'} syntax appears to be a valid JDBC standard and we have noticed it works ok in other JDBC drivers; e.g. Postgres, Oracle etc. So we wondering why it does not work for Denodo.

The documentation given in the community does not solve my problem it just makes it more complicated. Thu, 16 Jan 2020 08:13:05 GMT 2020-01-16T08:13:05Z LIST_JDBC_DATASOURCE_TABLES - 'Error getting tables and views.' Hello, I am attempting to perform some management/automation on Denodo and calling `LIST_JDBC_DATASOURCE_TABLES ` on an mssql datasource and it is failing with 'Error getting tables and views' after getting through 971 rows of tempdb, and no other databases. I am actually interested in objects from a different database and when I run my full query filtering on catalog name, schema and table names, I get 0 results before the error hits. Any way to find out more information on what the error is? I do not currently have access to the Denodo server OS, so hopefully there is somewhere in VDP Admin where you can check, or some option you can set to get some verbose output? Thank you Wed, 15 Jan 2020 21:54:48 GMT 2020-01-15T21:54:48Z Manage outlier with Denodo Good afternoon, how can I manage the outlier in Denodo. Verify that they exist and then be able to eliminate them. It is to say from a list of quantities I have values that are exaggeratedly high or exaggeratedly low that will interfere with my data.

We have a requirement to put the last modified/update date of each of the files (coming from different sources at different time). Is there a way to capture the file modification date and add that as a column in the base view ?
