The name of a table
A filter expression that evaluates to a logical value and selects a record from the table.
A CR-LF delimited list of the field values to write into the selected record. The data can be presented in two different formats as defined by the Style argument.
Default = 1. An optional style selector. See explanation below for more information.
.T. = the record was modified. .F. = the record was not modified.
Updates a record in a table. Data is CRLF delimited list. Style 1 - data is fieldname=fieldvalue pairs, Style 2 data is just fieldvalues in same order as fieldnames
RECORD_UPDATE() modifies a record in table Table_Name. The record is selected using Record_Filter and updated with the field values specified by Data_List.Note : If more than one record matches the filter, the function only modifies the first record found in record number order.
The following example changes the values of the firstname and lastname fields in the first record of the salespeople table.
dim str as C str = <<%dat% firstname = george lastname = white %dat% ? record_update("salespeople", ".t.", str) = .T.
Setting the Style
The Style selector defines the format of the data. There are two options available:
Style = 1
The default style used, data is listed using a CR-LF delimited list of <field_name> = <value> pairs. For example:
Fieldname1 = Value1 Fieldname2 = Value2 FieldnameN = ValueN
If data must be included for auto-increment fields, you must use Style 1. You can specify the auto-increment field with a blank value as follows:
Style = 2
Data only includes the values. For example:
Value1 Value2 ValueN
