Component Version macOS Windows Server FileMaker Cloud FileMaker iOS SDK
SQL 2.6 Yes Yes Yes Yes Yes
MBS( "SQL.Connect"; Connection; DBString { ; Username; Password; Client } )   More

Parameters

Parameter Description Example value
Connection The connection reference number gained with SQL.NewConnection. $Connection
DBString Database connection string.
Please specify port with comma after IP, not double colon.		 "/test/database.db"
Username Optional
The user name to use when establishing the connection.		 ""
Password Optional
The password to use when establishing the connection.		 ""
Client Optional
Optional, one of the following client values: CubeSQL, SQLAnywhere, ODBC, Oracle, SQLServer, Firebird, InterBase, SQLBase, DB2, Informix, Sybase, MySQL, PostgreSQL or SQLite.		 "SQLite"

Result

Returns "OK" or error message.

Description

Opens the connection to a data source.
Be aware that for most database servers, you need to specify client library with SQL.SetConnectionOption.

For server scripting, please use one connection for each script running on server, so multiple scripts running at the same data don't access the same connection or command objects in memory. And each connection has its own transaction and error state.

If you get a crash here on MacOS, please check if crash report says Code Signature Invalid. Then you may need to code sign the dylib yourself to match the code signature of your runtime application.
