ODBC escape syntax

You can use ODBC escape syntax from any ODBC application. This escape syntax allows you to call a set of common functions regardless of the database management system you are using. The general form for the escape syntax is

{ keyword parameters }

The set of keywords includes the following:

  • {d date-string}   The date string is any date value accepted by SQL Anywhere.

  • {t time-string}   The time string is any time value accepted by SQL Anywhere.

  • {ts date-string time-string}   The date/time string is any timestamp value accepted by SQL Anywhere.

  • {guid uuid-string}   The uuid-string is any valid GUID string, for example, 41dfe9ef-db91-11d2-8c43-006008d26a6f.

  • {oj outer-join-expr}   The outer-join-expr is a valid OUTER JOIN expression accepted by SQL Anywhere.

  • {? = call func(p1,...)}   The function is any valid function call accepted by SQL Anywhere.

  • {call proc(p1,...)}   The procedure is any valid stored procedure call accepted by SQL Anywhere.

  • {fn func(p1,...)}   The function is any one of the library of functions listed below.

You can use the escape syntax to access a library of functions implemented by the ODBC driver that includes number, string, time, date, and system functions.

For example, to obtain the current date in a database management system-neutral way, you would execute the following:

SELECT { FN CURDATE() }

The following tables list the functions that are supported by the SQL Anywhere ODBC driver.
