Hi , I am using a JDBC multitble to fetch data from SQLserver, then insert these records into the Mysql DB with same table structures, but when doing boolean type data, I got below error:

JDBC_23 - Can't coerce 'false' of type 'BOOLEAN' to column 'xxxxx'

Anyone can help me? Thank you!

The problem is that, technically, a BOOLEAN field is not a numeric type, but a BIT column in MySQL is. You can use Expression Evaluator to turn the BOOLEAN into an integer, and it will work. Just set your output field /xxxxx to an expression like:

${record:value('/xxxxx') ? 1 : 0}

For example:

mysql> select name, bin(value) from bit_table;
| name | bin(value) |
| Jim  | 1          |
| Bob  | 0          |
2 rows in set (0.00 sec)

Thanks a lot, it is working. I figure out a way with Field replacer and field type converter, but apparently, the solution you provided is easier and better. Thanks again.
