--TEST--
|
||||
Test for retrieving encrypted data of decimal types with different precisions and scales as output parameters
|
||||
--DESCRIPTION--
|
||||
Test implicit conversions between different precisions and scales
|
||||
With Always Encrypted, no implicit conversion works for decimal datatypes, the precision and scale specified in the SQLSRV_SQLTYPE must be identical to the precision and scale defined in the column
|
||||
Without AlwaysEncrypted, implicit conversion between precisions or scales works if:
|
||||
1. From a decimal(m1, m2) column to a SQLSRV_SQLTYPE_DECIMAL(n1, n2) output parameter where n1 - n2 >= m1 - m2
