Compatibility of Constants

This table describes the compatibility of constants between Adaptive Server Enterprise (ASE) and Sybase IQ.

This table is a guide only, and a marking of Both may not mean that the expression performs in an identical manner for all purposes under all circumstances. For detailed descriptions, see the Adaptive Server Enterprise documentation and the Sybase IQ documentation on the individual expression.

Default Interpretation of Delimited Strings
By default, Adaptive Server Enterprise and Sybase IQ give different meanings to delimited strings: that is, strings enclosed in apostrophes (single quotes) and in quotation marks (double quotes).
The quoted_identifier Option
Both Adaptive Server Enterprise and Sybase IQ provide a quoted_identifier option that allows the interpretation of delimited strings to be changed. By default, the quoted_identifier option is set to OFF in Adaptive Server Enterprise, and to ON in Sybase IQ.
