They convert dates between a string format and the internal DATE format. Customer Support HCLSoftware U Community Forums Customer Idea Portal. I need to be able to split the event durations into thirty minute intervals. Convert strings to time spans using TO_DATEPERIOD, TO_TIMEDURATION, or the cast operators ::DATE_PERIOD, ::TIME_DURATION. The interval of time to use to calculate the difference between date1 and date2. The DATEADD() function returns the data type that is the same as the data type of the date argument. (When you make a call to a CURRENT_ datetime function, the value that is returned is identical to the value returned to another call in the same node. Any subset of contiguous fields is also valid: for example, MINUTE TO FRACTION. CAST is a complex function that transforms one or more values from one data type into another. ; The interval data type, which encodes a span of time. Related reference: ESQL DATE data type. ; ESQL/C Guide The HCL OneDB™ ESQL/C Programmer's Manual explains how to use , the HCL OneDB™ implementation of Embedded Structured Query Language (SQL) for C (ESQL/C), to create client applications SQLSTATE is a database state function that returns a 5 character data type of CHARACTER with a you can access and update an external database resource using the available ESQL database functions in the Compute, Database, and An operation whose result is of type INTERVAL resulted in a value beyond the range supported by the INTERVAL data You must use the following HCL OneDB™ ESQL/C library functions for the datetime and interval data types to perform all operations on those types of values. The DAY TO FRACTION class has the format: DD HH:MM:SS. In earlier releases of WebSphere® Message Broker Version 8, the number of inputs wired to a transform and required to implement a transformation in a legacy message map was not enforced. The callback function provides a method for the application to regain control when the database server is processing an SQL request. A timeout interval is the amount of time (in milliseconds) for which the database server can process an SQL request before the application regains control. For example, commands that show how to specify a valid ESQL interval subtype ESQL DATE data type; ESQL TIME data type; ESQL GMTTIME data type; ESQL TIMESTAMP data type; ESQL GMTTIMESTAMP data type; ESQL INTERVAL data type; For information about datetime functions see ESQL datetime functions. For example, you can use the - (minus) operator to calculate the difference between two dates as an interval, or you can add an interval to a timestamp.
