ABL Reference
ABL Syntax Reference : GE or >= operator

GE or >= operator

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


expression { GE | >= } 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.


This procedure displays item information for those items whose OnHand value is greater than or equal to 120:
FOR EACH Item NO-LOCK WHERE Item.OnHand >= 120:
DISPLAY Item.ItemNum Item.ItemName Item.OnHand.


*By default, the AVM 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 the AVM accesses during the session, except when the AVM uses or modifies pre-existing indexes. If you do not specify a collation with the -cpcoll startup parameter, the AVM 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, the AVM 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 ABL. 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 cannot compare data of different DATE, DATETIME, and DATETIME-TZ data types to each other using GE. You must first convert different date and datetime data types to the same data type before doing a comparison between them.
*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 the AVM raises a run-time error.
*You cannot use GE to compare any of the LOB data types, including BLOB or CLOB.
*You can use GE to compare two enums, including both ABL and .NET enums, as long as they are the same enum type. GE compares the underlying numerical values of the enumerators.
