Description

Updates existing records in a table in one line using JSON.
You pass to this function table name (and optional filename).
To identify the record you pass the name of the ID field and the value for the record. The ID field must not be unique, so several records can be updated at once.
Then you pass one pair of field name and value for each field you like to set in the new record.

Please note that JSON.UpdateRecord and JSON.UpdateRecords are nearly identical. Just JSON.UpdateRecord provides the check to make sure only one record matches while JSON.UpdateRecords allows several records to be updated. So with JSON.UpdateRecords you can easily erase a lot of data if you pass wrong ID!

You can specify fields and table via IDs and the plugin will lookup them for you at runtime. Table IDs and table names must be unique across all open files for this to work correctly.

You can use GetFieldName() function to query field names and the plugin removes the table prefix with :: in the field name before passing it to SQL engine.

You can use FM.ExecuteSQL.LastSQL function to see later what SQL was created and run.
