JDBC driver on Mariadb, creates empty tables when having Unicode characters in content #2922

Open hermygithub opened 4 months ago

Describe the bug using JDBC driver on Mariadb, creates empty tables and references a column 'u' that is not in the query. it just creates an empty table in mariadb and gives a java.sql.SQLException (cfr screenshot below)

It looks like Drill's JDBC writer needs to gain support for Unicode escape sequences in its input data.

To Reproduce Steps to reproduce the behavior:

Expected behavior when there are unicode characters in varchar columns written to a table via a JDBC connection, it should create the table and populate that table by supporting unicode data loading into the sql database table
