--TEST--
|
|
Test for inserting encrypted data of float types with different number of bits
|
|
--DESCRIPTION--
|
|
Test implicit conversions between different number of bits
|
|
With Always Encrypted, implicit conversion works if:
|
|
1. From input of SQLSRV_SQLTYPE_FLOAT to a float(m) column where m > 24
|
|
Note: with Always Encrypted, implicit conversion should work as long as the SQLSRV_SQLTYPE has a smaller number of bits than the one defined in the column. However, the SQLSRV driver does not let the user specify the number of bits in the SQLSRV_SQLTYPE_FLOAT constant and it is default to 53. Hence when user specifies SQLSRV_SQLTYPE_FLOAT when binding parameter during insertion, only insertion into a column of > 24 is allowed.
|
|
Without Always Encrypted, implicit conversion between different number of bits works.
