lookupmoreformula(
FORMULA
,
DEFAULT
)
The lookupmoreformula( function looks up additional data based on a previous lookup.
Parameters
This function has two parameters:
formula – is the formula that will be used to extract data from the target database. The entire formula must be enclosed in quotes (see Quotes). This formula will be evaluated using the database specified by the previous lookup( or superlookup( function.
default – is the value you want this function to return if the previous lookup formula failed to find a match. The data type of the default value should match the result type of the Formula parameter. If the formula is numeric, the default should usually be zero. If the formula is text, the default should usually be "". Note: This parameter is optional. If it is omitted, the lookupmoreformula( function will return an error if the search fails.
Description
This function is designed to retrieve additional information after a lookup( function. In this example, the procedure looks up a check from a Checkbook database. It first retrieves who the check was written to, then retrieves the age of the check (in days – today’s date minus the date of the check.)
Vendor = lookup("Checkbook","Number",ckNumber,"PayTo")
Age = lookupmoreformula({today()-Date})
The lookupmoreformula( function works with any lookup function, including lookup(, lookuplast(, lookupselected(, lookuplastselected(, and superlookup(. (It does not, however, work with the table( function.)
Error Messages
lookupmoreformula( function failed because previous lookup failed. – This function should only be used immediately after a lookup function.

- formulavalue( -- calculates the result of a formula based on data in the current record of any open database. This is similar to the fieldvalue( function, but allows any formula to be used, rather than just a single field.
- globaldictionarybuild -- builds a global dictionary by scanning a database.
- join -- joins data from another database into the current database.
- joinonerecord -- joins matching data from another database into the current record.
- lastlookupdatabase( -- returns the name of the database referenced in the most recent lookup.
- lookup( -- searches a database for a value, then returns other information from the same record. For example, the *lookup(* function can look up a phone number given a customer name, or look up a price given a part number.
- lookupall( -- builds a text array containing one item for every record in the target database where the data in the keyField matches the keyData. Each item in the text array contains the value extracted from the dataField for that record. If the data field is a numeric or date field, it is converted to text using the default patterns for that field.

- lookupalltriple( -- is similar to the lookupall( function, but it returns three fields from the target database instead of just one.
- lookuplast( -- searches the selected records in a database for a value, then returns other information from the same record. For example, the *lookuplast(* function can look up a phone number given a customer name, or look up a price given a part number. Unlike the lookup( function which searches from the top of the database, the *lookuplast(* function searches backwards from the bottom.
- lookuplastselected( -- searches the selected records in a database for a value, then returns other information from the same record. For example, the *lookuplastselected(* function can look up a phone number given a customer name, or look up a price given a part number. Unlike the lookupselected( function which searches from the top of the database, the *lookuplastselected(* function searches backwards from the bottom.
- lookupmoredata( -- looks up an additional data field based on the previous lookup.
- lookupselected( -- searches the selected records in a database for a value, then returns other information from the same record. For example, the *lookupselected(* function can look up a phone number given a customer name, or look up a price given a part number.
- related( -- searches a database for a record in a related database that matches the current record in the current database based a relational specification (based on one or more key fields or formulas in each database), then uses a formula to return other information from the same record. This is similar to the lookup( function, but instead of using an individual field for the key, a relation is used (see Relational Database Management).
- relatedarray( -- builds an Text Array by scanning a database and creating an array element for every record that matches a relational specification (based on one or more key fields or formulas). This is similar to the arraybuild( function, but instead of using an individual field for the key, a relation is used (see Relational Database Management).
- relatedrecordid( -- returns the record id of a record in a related database that matches the current record in the current database based on a relational specification.

- serverlookup( -- searches a shared database for a value, then returns other information from the same record. Similar to the lookup( function, but the search is performed on the server instead in the local computer's memory.
- superlookup( -- searches a database for a record that matches a query formula, then uses a second formula to return other information from the same record. This is similar to the lookup( function, but instead of using an individual field for the key and data, any valid true/false (Boolean) formula can be used.
- table( -- searches a database for a value, then returns other information from the same record. Unlike the lookup( function, the *table(* function does not require an exact match. If it does not find an exact match the *table(* function will use the closest match. For example, the *table(* function can look up a tax rate given an income amount, or look up a shipping price given a zip code and weight.
