Progress Function Support
Table 2–2 lists the Progress functions that are supported in ESQL. Any other Progress functions permitted in Progress/SQL are not permitted in ESQL. However, ANSI standard SQL aggregate functions (such as AVG and COUNT) are permitted in Progress/ESQL.
When you reference Progress identifiers (for example, table fields (or columns) or function names) that contain hyphens in Progress/ESQL, precede the hyphen with a backslash (\) to escape the hyphen. If you do not insert a backslash before the hyphen, the SQL preprocessor interprets the hyphen (-) as a minus sign because hyphens are not permitted in ANSI standard SQL identifiers.
