How do I get the current date in DataStage?
You can use IConv to convert a string into a datastage internal date format. Then you can perform addition/subtraction on the date. Then use OConv to convert the variable back to string format. Hope this helps.
How do I add months to a date in DataStage?
‘Oconv(Iconv(date,”D”),DM) + counter’ to add up the month.
What is CDC stage in DataStage?
The Change Capture stage takes two input data sets, denoted before and after, and outputs a single data set whose records represent the changes made to the before data set to obtain the after data set.
What are active and passive stages in DataStage?
Actives stages, such as the Transformer and Aggregator, perform processing tasks, while passive stages, such as the Sequential File stage and Hashed File stage, are reading or writing data sources and provide services to the active stages.
What is Iconv and Oconv functions in DataStage?
ICONV and OCONV functions are quite often used to handle data in Datastage. ICONV converts a string to an internal storage format and OCONV converts an expression to an output format.
How do you pass a date as a parameter in DataStage?
following steps below:
- Using the ‘Execute Command Activity’ stage, execute a tail -1 on the. file (providing either the file has one row or the info is in the last row).

How do I remove duplicates in DataStage?
The Remove Duplicates stage is a processing stage. It can have a single input link and a single output link. The Remove Duplicates stage takes a single sorted data set as input, removes all duplicate rows, and writes the results to an output data set.
What is CDC transaction?
A CDC Transaction stage that specifies details about accessing your installation of InfoSphere CDC. The following output links from the CDC Transaction stage: An output link for each table in the subscription. These output links transfer change data from InfoSphere CDC to another stage or to a target database.
What is active stage in DataStage?
Actives stages, such as the Transformer and Aggregator, perform processing tasks, while passive stages, such as the Sequential File stage and Hashed File stage, are reading or writing data sources and provide services to the active stages. At its simplest, active stages become processes.
What is funnel stage in DataStage?
The Funnel stage is a processing stage that copies multiple input data sets to a single output data set. You can use this operation for combining separate data sets into a single large data set. The Funnel stage is a processing stage. It copies multiple input data sets to a single output data set.
How do I add a parameter set in DataStage?
Create a parameter set.
- From the Designer client menu, click Edit > Job Properties.
- In the Job Properties window, click the Parameters tab.
- Hold the Ctrl key, then click each of the parameters that you created in the previous lesson.
- Click Create Parameter Set.
What are job parameters in DataStage?
Datastage 8 implements also job parameters sets which let users group the DataStage and QualityStage job parameters and store default values in files. Job parameters are defined in job properties windows. Parameters can be used in directory and file names, to specify property values and in constraints and derivations.
Why are date functions important in Excel?
The Excel DATE function creates a valid date from individual year, month, and day components. The DATE function is useful for assembling dates that need to change dynamically based on other values in a worksheet.
Can duplicates be removed using copy stage?
The data set input to the Remove Duplicates stage must be sorted so that all records with identical key values are adjacent. You can either achieve this using the in-stage sort facilities available on the Input page Partitioning tab, or have an explicit Sort stage feeding the Remove Duplicates stage.
How do I find unique and duplicate records in DataStage?
Solution:
- Here I enable ‘Row Number Column’ property in sequential stage in order to generate unique number(this will be used in next stage) for each input record.
- In next step, take a copy stage to pass the input into two output links.
- Compile job and run the job.
- You can see the duplicate records in the output.
What is an example of a time stamp function?
Examples. If mylink.basetime contains 14:05:29.30 and mylink.secos contains the value 2.5, then the two following functions are equivalent, and return the time 14:05:31.80. Returns a time stamp from the given date and time.
How do you use date and time in a transformer?
You can use the date and time functions to perform various operations on dates and times in the Transformer stage. Functions that have the days of week in the argument take a string that specifies the day of the week. The day is specified as a three-letter abbreviation, or the full name.
How are offset values applied to a date?
Returns the given date, with offsets applied from the given year offset, month offset, and day of month offset, given as three separate values. The offset values can each be positive, zero, or negative.
How do I add time to the output data?
Use this function to add a new column that contains the time to the output data by the Transformer stage. You must set the Extended field in the column metadata to Microseconds to contain the full time. Returns a time stamp that gives the date and time that the job runs.
