--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.
