To set default values for these settings visit Tools->Tool Properties and the General / SQL Commander category. DbVisualizer will then report errors reported by the JDBC driver only.

With Show Error Position Markers turned on it shows markers only for databases that specifically report positions of errors in a statement. Disable Error Markers in the SQL Editorįrom DbVisualizer 10.0.5 it is possible to disable error markers in the SQL Commander->SQL Commander Options menus. In that case the complete statement is underlined in the editor. Error location information is not available for some databases.
