--TEST--
|
|
Test for inserting encrypted data of decimal types with different precisions and scales
|
|
--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 input of SQLSRV_SQLTYPE_DECIMAL(n1, n2) to a decimal(m1, m2) column where n1 - n2 > m1 - m2 and
|
|
2. where n2 != 0 && m1 != m2
