Getting "Invalid column type" excecption, while using NamedParameterJDBCTemplate for insertion

You are getting this exception because you are using JdbcTemplate instead of NamedParameterJdbcTemplate. MapSqlParameterSource works with NamedParameterJdbcTemplate.

You might want to try using strings instead of characters for your CHAR(1) Y/N fields.

Try changing your code to:

paramSource.addValue("NAME1",sponsor.getName(), Types.VARCHAR);
paramSource.addValue("INDUSTRY_TYPE", sponsor.getIndustryType(), Types.INTEGER);
paramSource.addValue("IS_NOT_SOLICITE", sponsor.getNotSoliciteFlag()?'Y':'N', Types.CHAR);
paramSource.addValue("IS_REPORTING_SPONSOR", sponsor.getReportingFlag()?'Y':'N', Types.CHAR);
