--TEST--
|
|
Test for inserting encrypted data of datetime2, datetimeoffset and time datatypes with different precisions
|
|
--DESCRIPTION--
|
|
Test implicit conversions between different precisions
|
|
With Always Encrypted, implicit conversion works if:
|
|
1. From input of SQLSRV_SQLTYPE_DATETIME2 to a dateteim2(7) column
|
|
2. From input of SQLSRV_SQLTYPE_DATETIMEOFFSET to a datetimeoffset(7) column
|
|
3. From input of SQLSRV_SQLTYPE_TIME to a time(7) column
|
|
Note: with Always Encrypted, implicit converion should work as long as the SQLSRV_SQLTYPE has a smaller precision than the one defined in the column. However, the SQLSRV driver does not let the user specify the precision in these SQLSRV_SQLTYPE_* constants and they are all default to a precision of 7. Hence when user specifies SQLSRV_SQLTYPE_DATETIME2, SQLSRV_SQLTYPE_DATETIMEOFFSET or SQLSRV_SQLTYPE_TIME when binding parameter during insertion, only insertion into a column of precision 7 is allowed.

|
Without AlwaysEncrypted, implicit conversion between different precisions works
