TRUNCATE_TIMESTAMP_VALUES option [database]

Function  

Limits the resolution of timestamp values.

Allowed values  

ON, OFF

Scope  

Can be set for the PUBLIC group. This option should not be enabled for databases already containing timestamp data.

Default  

OFF

Description  

A TIMESTAMP value is precise to six decimal places in Adaptive Server Anywhere. However, to maintain compatibility with other software, which may truncate the TIMESTAMP value to three decimal places, you can set the TRUNCATE_TIMESTAMP_VALUES option to ON to limit the number of decimal places Adaptive Server Anywhere stores. The DEFAULT_TIMESTAMP_INCREMENT option determines the number of decimal places to which the TIMESTAMP value is truncated.

Example 

Setting the DEFAULT_TIMESTAMP_INCREMENT option to 100 000 causes truncation after the first decimal place in the seconds component, allowing a value such as '2000/12/05 10:50:53:700' to be stored.
