Defines a SQL Evaluate function for JavaScript.
The function will take string parameter with file name and SQL and evaluate the result in FileMaker. Result is returned as text to JavaScript. You can pass additional parameters for filling parameters in SQL.

For increased security we prefer all FileMaker developers define their own function name, so if you get some foreign JavaScript, it can't know the function name and mess with FileMaker. Be aware that users may run commands like DELETE to delete all records of a table!


Run SQL from JavaScript:

Set Variable [ $js ; Value: MBS( "JS.New" ) ]
Set Variable [ $r ; Value: MBS( "JS.AddFileMakerSQLFunction"; $js; "FMSQL") ]
Show Custom Dialog [ "Result" ; MBS( "JS.Evaluate"; $JS; " \"got SQL result: \" + FMSQL(\"JavaScript.fmp12\", \"SELECT COUNT(*) FROM JavaScript\")" ) ]
Set Variable [ $r ; Value: MBS( "JS.Release"; $JS ) ]

Create JavaScript environment with SQL function to query FileMaker tables:

Set Variable [ $$JS ; Value: MBS("JS.New") ]
Set Variable [ $r ; Value: MBS( "JS.AddFileMakerSQLFunction"; $$js; "FMSQL") ]
