Openedge Data Management: SQL Reference - Product ...

column_name data_type
COLLATE
CREATE TABLE
Names a column and associates a data type with it. The column names specified must
be different from other column names in the table definition. The data_type must be
supported by OpenEdge. For more information on supported datatypes, see the
“OpenEdge SQL Language Elements” section on page 189.
When a table contains more than one column, a comma separator is required after
each column_definition except for the final column_definition.
Indicates the column’s case sensitivity. Note the default is case_sensitive.
case_insensitive
Indicates the column will be case insensitive. The word case_insensitive itself
cannot be used as a valid input. The value for the case_insensitive clause here can
only be _I, I, or the default database collation with the suffix _I (for example:
COLLATE_I, COLLATE I, or COLLATE BASIC_I).
case_sensitive
DEFAULT
Indicates the column will be case sensitive. The word case_sensitive itself cannot
be used as a valid input. The value for the case_sensitive clause here can only be
_S, S, or the default database collation with the suffix _S (for example: COLLATE_S,
COLLATE S, or COLLATE BASIC_S).
Specifies an explicit default value for a column. The column takes on the value if an
INSERT statement does not include a value for the column. If a column definition
omits the DEFAULT clause, the default value is NULL.
The DEFAULT clause accepts the arguments shown in the following table:
literal An integer, numeric, or string constant.
NULL A null value.
SYSDATE The current date. Valid only for columns defined with DATE
data types. SYSDATE is equivalent to the Progress default
keyword TODAY.
SYSTIME The current time. A TIME value.
SYSTIMESTAMP The current date and time. A TIMESTAMP value.
column_constraint
Specifies a constraint that will be applied while inserting or updating a value in the
associated column.
