CHAPTER 14
When Adaptive Server IQ is serving applications over TDS, it automatically
sets relevant database options to values that are compatible with Adaptive
Server Enterprise default behavior. These options are set temporarily, for the
duration of the connection only. They can be overridden by the client
application at any time.
The database options that are set on connection using TDS are as follows:
Option
ALLOW_NULLS_BY_DEFAULT
ANSINULL
AUTOMATIC_TIMESTAMP
CHAINED
CONTINUE_AFTER_RAISERROR
DATE_FORMAT
DATE_ORDER
ESCAPE_CHARACTER
ISOLATION_LEVEL
FLOAT_AS_DOUBLE
QUOTED_IDENTIFIER
TIME_FORMAT
TIMESTAMP_FORMAT
TSQL_HEX_CONSTANT
TSQL_VARIABLES
The default database options are set for TDS connections using a system
procedure named
sp_tsql_environment
options:
SET TEMPORARY OPTION TSQL_VARIABLES='ON';
SET TEMPORARY OPTION ANSI_BLANKS='ON';
SET TEMPORARY OPTION TSQL_HEX_CONSTANT='ON';
SET TEMPORARY OPTION CHAINED='OFF';
SET TEMPORARY OPTION QUOTED_IDENTIFIER='OFF';
SET TEMPORARY OPTION ALLOW_NULLS_BY_DEFAULT='OFF';
SET TEMPORARY OPTION AUTOMATIC_TIMESTAMP='ON';
SET TEMPORARY OPTION ANSINULL='OFF';
SET TEMPORARY OPTION CONTINUE_AFTER_RAISERROR='ON';
SET TEMPORARY OPTION FLOAT_AS_DOUBLE='ON';
SET TEMPORARY OPTION ISOLATION_LEVEL='1';
