Alter on Base View - Add Trim

I would like to add Trim() function to the column in the base view to remove the default spaces for CHAR data type. Can I do this by running an alter statement? I need to do this across all the coulumn in the Source, Is there any setting to do trim by default for all source columns.

Hi, In order to remove the default spaces for CHAR or TEXT data type fields, I would check the option “Ignore trailing spaces” under the “Read & Write” tab of the ODBC or JDBC data source. If this option is selected, Virtual DataPort will remove the unneeded space characters at the end of the CHAR/TEXT type values of the results obtained by the data source’s views. Using this option you don’t need to apply the trim function. You can refer to subsection [“Read & Write” tab](https://community.denodo.com/docs/html/browse/6.0/vdp/administration/creating_views/importing_data_sources_and_creating_base_views/jdbc_sources#importing-jdbc-sources) under the section ‘**Importing JDBC Sources**' of the Virtual DataPort Administration Guide to know more information. Hope this helps!!
