SPLICE Operator
SPLICE Operator (for Experienced)
Summary
For basic information, go through the SPLICE Operator (for Beginners)
- SPLICE operator joins specified fields together from records with the same values (duplicate values) but with different information in other areas.
- It combines specified fields from two or more records to create an output record.
- The fields to be joined can originate from different datasets.
- SPLICE operator also makes it possible to join fields from different input records to create an output record with information from two or more records.
- SPLICE operator allows up to 10 ON fields and 50 WITH fields.
Syntax -
Required Operands
FROM -
- FROM parameter specifies ddname of the input file.
- indd DD statement is mandatory if FROM operand specified.
TO -
- TO operand specifies 1 to 10 ddnames of output files.
- outdd DD statement is mandatory if TO operand specified
- Either TO, USING, or both operands can code at the same time.
ON -
- ON operator specifies the field(s) used for DISPLAY operation.
- 1 to 50 ON fields can be specified with the DISPLAY operation.
- (p,m,f) gives the position, length, and format of a numeric or character field. The field should not be beyond position 32752 or the end of the record.
- (p,m,f, formatting) gives a numeric or character field's position, length, and format. It also specifies how the data is to be formatted for printing for this field. The field should not be beyond position 32752 or the end of the record.
- VLEN is equivalent to ON(1,2, BI) for variable-length records, representing each record's record length.
Optional Operands
VSAMTYPE -
- VSAMTYPE operand specifies the record format for a VSAM input file (F or V).
WITHALL -
- WITHALL is used to splice the first duplicate with all the WITH fields from the second and subsequent duplicates.
WITHANY -
- WITHANY is used to splice the first duplicate with nonblank WITH fields from the second and subsequent duplicates.
WITHEACH -
- WITHEACH is used to splice the first duplicate with one WITH field from the second and subsequent duplicates.
- By default, non-matching records are not kept.
KEEPNODUPS -
- KEEPNODUPS is used to keep non-matching records.
- By default, the base record is not kept.
KEEPBASE -
- KEEPBASE is used to keep the base record.
UZERO -
- Causes -0 to be treated as unsigned, that is, as 0.
USING -
- USING operand specifies the first 4-characters of the ddname (xxxxCNTL) for the DFSORT control statement file.
- XXXX name is the user-defined name.
- xxxxCNTL DD statement is mandatory if USING(xxxx) is specified.
- Either TO, USING, or both operands can code at the same time.
Example -
Scenario - Create one spliced record for each match in two files.
In this example, we are joining employee details with employee salary based on employee number(columns 1-3).
