initQuery

One or more SQL statements for the proxy to run when opening each new database connection. The setting is typically used with SET statements to make sure that each connection has identical settings. The query added here must be valid. For including multiple variables in a single SET statement, use a comma separator. This is an optional field.

For example: SET variable1=value1, variable2=value2

Since you can access initialization query as part of target group configuration, it is not protected by authentication or cryptographic methods. Anyone with access to view or manage your proxy target group configuration can view the initialization query. You should not add sensitive data, such as passwords or long-lived encryption keys, to this option.
