Release 10.1A: OpenEdge Development:
Progress 4GL Reference

> ## GE or >= operator

> Returns a TRUE value if the first of two expressions is greater than or equal to the second expression.

> #### Syntax

>     expression { GE | >= } expression

> ``expression``

> A constant, field name, variable name, or any combination of these. The expressions on either side of the GE or >= must be of the same data type, although one might be integer and the other decimal.

> Example

> This procedure displays item information for those items whose on-hand value is greater than or equal to 120:

> r-ge.p
>     FOR EACH item WHERE on-hand >= 120:
>       DISPLAY item.item-num item-name on-hand.
>     END.

> #### Notes

> - By default, Progress uses the collation rules you specify to compare characters and sort records. The collation rules specified with the Collation Table (`-cpcoll`) startup parameter take precedence over a collation specified for any database Progress accesses during the session, except when Progress uses or modifies pre-existing indexes. If you do not specify a collation with the -`cpcoll` startup parameter, Progress uses the language collation rules defined for the first database on the command line. If you do not specify a database on the command line, Progress uses the collation rules with the default name "`basic`" (which might or might not exist in the `convmap.cp` file).

> - If either of the expressions is the Unknown value (`?`), then the result is the Unknown value (`?`); if both expressions are the Unknown value (`?`), then the result is TRUE.

> - You can compare character strings with GE. Most character comparisons are case insensitive in Progress. That is, upper-case and lower-case characters have the same sort value. However, it is possible to define fields and variables as case sensitive (although it is not advised, unless strict ANSI SQL adherence is required). If either `expression` is a field or variable defined as case sensitive, the comparison is case sensitive and “Smith” does not equal “smith”.

> - Characters are converted to their sort code values for comparison. Using the default case-sensitive collation table, all uppercase letters sort before all lowercase letters (for example, a is greater than Z, but less than b.) Note also that in character code uppercase A is less than [ , \ , ^ , _, and ’ , but lowercase a is greater than these.

> - You can use GE to compare DATE, DATETIME, and DATETIME-TZ data. The data type that contains less information (that is, a DATE value contains less information than a DATETIME value, and a DATETIME value contains less information than a DATETIME-TZ value) is converted to the data type with more information by defaulting the time value to midnight, and the time zone value to the session's time zone (when the data type does not contain the time or time zone). Comparisons with DATETIME-TZ data are based on Coordinated Universal Time (UTC) date and time.

> - You can use GE to compare a LONGCHAR variable to another LONGCHAR or CHARACTER variable. The variable values are converted to `-cpinternal` for comparison and must convert without error, or Progress raises a run-time error.

> - You cannot use GE to compare one CLOB field to another.
