--TEST--
Test for inserting and retrieving encrypted data of numeric types
Test for inserting encrypted data into decimal types columns
--DESCRIPTION--
Use PDOstatement::bindParam with all PDO::PARAM_ types
Test conversions between different decimal types
With Always Encrypted, implicit conversion works if:
1. From input of PDO::PARAM_BOOL to a any decimal column
2. From input of PDO::PARAM_INT to a any decimal column
3. From input of PDO::PARAM_STR to a any decimal column
4. From input of PDO::PARAM_LOB to a any decimal column
Without Always Encrypted, all of the above should work except for:
1. From input of PDO::PARAM_STR to a decimal column and the input has more than 14 digits to the left of the decimal
