DATABASE 90 schema sequence Specifies the schema that contains the sequence. To refer to the current value of a sequence in the schema of another user, you must have SELECT object privilege on the sequence. Specifies the name of the sequence whose current value you want. Use CURRVAL in: • The SELECT list of a SELECT statement not contained in a subquery or view • The SELECT list of a subquery in an INSERT statement • The VALUES clause of an INSERT statement • The SET clause of an UPDATE statement CURRVAL cannot be used in: • A query of a view • A SELECT statement with a GROUP BY clause that references a sequence • A SELECT statement with an ORDER BY clause that references a sequence • A SELECT statement that is combined with another SELECT statement with the UNION, INTERSECT, or MINUS set operator • The WHERE clause of a SELECT or UPDATE statement • The DEFAULT value of a column in a CREATE TABLE or ALTER TABLE statement • The condition of a CHECK constraint Example In the following example, the OpenEdge <strong>SQL</strong> sequence generator returns the current value of the customer sequence: DATABASE Syntax SELECT customer_sequence.CURRVAL FROM pub.customer; Returns the name of the database corresponding to the current connection name. This function takes no arguments, and the trailing parentheses are optional. DATABASE [ ( ) ] Example The following example shows how to use the DATABASE function:
DAYNAME Syntax Compatibility ODBC compatible DAYNAME Returns a character string containing the name of the day (for example, Sunday through Saturday) for the day portion of date_expression. The argument date_expression can be the name of a column, the result of another scalar function, or a date or timestamp literal. Example This example illustrates the DAYNAME function: DAYOFMONTH Syntax select database() from t2; DATABASE -------steel 1 record selected DAYNAME ( date_expression ) SELECT * FROM orders WHERE order_no = 342 and DAYNAME(order_date)= 'SATURDAY'; ORDER_NO ORDER_DATE REFERENCE CUST_NO -------- ----------- ---------- -------- 342 08/10 tdfg/101 10001 1 record selected Compatibility ODBC compatible Returns the day of the month in the argument as a short integer value in the range of 1–31. The argument date_expression can be the name of a column, the result of another scalar function, or a date or timestamp literal. DAYOFMONTH ( date_expression ) Example This example illustrates the DAYOFMONTH function: 91
