Syntax
InmemoryLookup(table Table, scalar|vector lookupColumnKey, scalar lookupColumnValue, scalar|vector defaultValue, vector lookupValue1, vector lookupValue2,..)
Arguments
| Argument | Description |
|---|---|
table Table | Lookup table |
| `scalar | vector lookupColumnKey` |
scalar lookupColumnValue | Value column from the lookup table |
| `scalar | vector defaultValue` |
vector LookupValue(s) | Key columns from the input table |
Examples:
InmemoryLookup([[FusionTestTable2]], "VarcharColumn", "PhoneNumCol", "", [FusionTestTable.VarcharColumn])
Looks up the VarcharColumn from the FusionTestTable with the VarcharColumn of FusionTestTable2 and returns the corresponding value of the PhoneNumCol and returns "" when the value is not found.
InmemoryLookUp([[FusionTestTable2]],array("VarcharColumn","SmallIntColumn"), "PhoneNumCol", "", [FusionTestTable.VarcharColumn],[FusionTestTable.SmallIntColumn])
Looks up the VarcharColumn and the SmallIntColumn from the FusionTestTable with the VarcharColumn and the SmallIntColumn of FusionTestTable2 and returns the corresponding value of the PhoneNumCol and returns "" when the value is not found.
