Syntax
CEILING
If the expression evaluates to NULL, the result of the function is null. Specifying NULL with the
CAST function is useful for set operations, such as UNION, that require two tables to have the same
structure. CAST NULL allows you to specify a column of the correct data type, so a table with a
similar structure to another, but with fewer columns, can be in a union operation with the other
table.
The CAST function provides a data-type-conversion mechanism compatible with the SQL
standard.
Use the CONVERT function, enclosed in the ODBC escape clause { fn }, to specify
ODBC-compliant syntax for data type conversion. See “CONVERT (ODBC compatible)” section
on page 86 for more information.
Example The following SQL example uses CAST to convert an integer field from a catalog table to a
CHARACTER data type:
CEILING
Syntax
CAST ( { expression | NULL } AS data_type [ ( length )] )
SELECT CAST(fld AS CHAR(25)), fld FROM sysprogress.syscalctable;
CONVERT(CHARACTER(25),FLD) FLD
-------------------------- ---
100 100

Returns the smallest integer greater than or equal to expression.
CEILING ( expression )
Example This example illustrates the CEILING function:
SELECT CEILING (32.5) 'Ceiling'
FROM SYSPROGRESS.SYSCALCTABLE;
Note The expression must evaluate to a numeric data type.
