--TEST--
|
|
Test for inserting encrypted data into decimal types columns
|
|
--DESCRIPTION--
|
|
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
