LOOKUPTABLEVALUE2_DEFAULT
Syntax
LOOKUPTABLEVALUE2_DEFAULT (table_name, expression, default_value)
Description
Takes a value in column 1 of the named lookup table to find the value in column 2.
Arguments
| table_name | The name of the lookup table. |
| expression | A value in column 1 of the named lookup table. The value can be any string expression. |
| default_value | The value to insert if no there is no matching value in column 1. |
Returns
Either:
- A string with the corresponding value in column 2 of the lookup table.
- The default value if there is no matching value in column 1.
Remarks
If the lookup value or the value being looked up is a NULL, the value is converted to its native data type, and then, if necessary, converted to a string before it is used in the lookup. Before the lookup occurs, if the source value is:
- A NULL of type int, it is converted to a 0.
- A NULL of type string, is converted to an empty string.
If the value in the expression argument is listed more than once in the lookup table, TIBCO Scribe® Online returns a row error.
